I am a 30 years old male and since last 3 months I was having pain in right leg whenever I used to walk. My doctor advised me Lumbosacral MRI and my findings are as under: 1. Lumbar lordosis is mildly straightened. 2. Disc desiccation noted at L5-S1 noted. 3. Posterior disco osteophytes complex seen at L5-S1 level causing canal stenosis measuring 7mm and bilateral lateral recess stenosis, causing compression upon traversing S1 nerve roots and mild foramina narrowing with abutting bilateral L5 nerve roots. 4. Mild diffuse disc bulge at L4-5 level causing indentation of thecal sac with early lateral recess stenosis, however no significant neural compression seen.
Different methods to treat Disc problems
I am a 25 years old male, I have been suffering from bulging disk at l5-s1. I have been resting for 2 months, now my neck has started paining too and left pelvic joint is making popping sound everytime it is bend. So I got my blood acid checked. And its been 8 for last two months, I have been drinking like 6 lts water everyday. Is uric acid main reason of pain? And how can I get it down as I don't want to start the medicine so early in life and drinking water is not working. Please suggest, my career is suffering a lot.
My age is 22 I have slip disk my disk dislocated into 6 mm back so I have heavy pain when I bend or doing any work and long time sitting any home remedies to cure fast.
In case you have a diseased uterus, which makes you infertile, you can undergo a procedure known as uterus transplant or uterine transplant to get pregnant. In the process of sexual reproduction, a diseased uterus does not allow embryonic implantation. This factor is referred to as uterine factor infertility or UFI. As a result, you will not be able to get pregnant. Learn more about having healthy pregnancy.
Who requires a uterus transplant?
This procedure involves women who have UFI and women who had their uterus removed by hysterectomy. Women who have a damaged uterus on account of an injury or infection, which does not function anymore, can also undergo a uterus transplant procedure. Women from the age of 21 to 45 are eligible for this procedure. Many women are born without having a uterus. This condition is called Mayer-Rokitansky-Küster-Hauser syndrome.
Uterus transplantation begins with undertaking a uterus retrieval surgery on the uterus donor. The uterus, which is recovered has to be stored and transported to the location of the patient undergoing the transplant. An ischemic tolerance may last over 24 hours. Three major surgeries have to be carried out with the recipient. Firstly, a transplantation surgery is required in which the donor’s uterus gets transplanted. In case pregnancy develops, a caesarean section surgery has to be performed. The patient is given immune suppressive therapy. After childbirth, a hysterectomy is done in order to terminate the immune suppressive therapy.
Will the women be able to get pregnant after having sex?
Women receiving a uterus transplant will not be capable of becoming pregnant without undergoing fertility treatments. The transplanted uterus is not connected with the fallopian tubes, which is the location of the normal fertilisation process. The women will require to carry out IVF or in vitro fertilisation to become pregnant after a uterus transplant. IVF is a process in which the eggs are removed from the ovaries and get fertilised in a laboratory. Then, they are implanted in the uterus. After undergoing the uterus transplant procedure, a woman has to wait for a period of one year. The uterus requires time for healing and after recovery, the embryo may be implanted for pregnancy. After giving birth successfully, a woman will be able to keep the transplanted uterus. This is a reason why IVF is a popular procedure.
She has the option to get pregnant again. However, after giving birth twice, a hysterectomy must be carried out for the removal of the uterus. This is done so that the woman can stop using the immune suppressant drugs, which are associated with major risks. Uterus transplant is a relatively new technology. In October 2014, the first healthy baby was born to a woman who had undergone a uterus transplant. This surgery is kind of experimental in nature and is usually the last option for getting pregnant.
I have been suffering from disk problem since 7 months. I have consulted a doctor. I took x-Ray as per his advice. He said disk has been narrowed. He prescribed some painkillers and vitamin tablets. Could anyone please prescribe some medicine for me. I am really unable to sit without any support.
Are you experiencing excessive uterine bleeding? Excessive uterine bleeding may occur between a woman’s periods or before the periods, after having sex, or due to the development of spotting or bleeding after attaining menopause. Any menstrual cycle, which lasts longer than 21–35 days is called excessive, and this is an abnormal form of uterine bleeding.
Causes of Excessive Uterine Bleeding:
The various causes of excessive uterine bleeding are as follows:
One of the main causes is hormonal imbalance, as the balance between estrogen and progesterone gets disrupted. This balance is required for the regulation and development of the lining of endometrium or uterus lining. Because of the hormonal imbalance, the endometrium develops excessively causing heavy bleeding.
Uterine fibroids, which are non cancerous tumours, may lead to prolonged and excessive uterine bleeding.
Polyps are small benign developments on the uterus lining which cause heavy bleeding. They occur because of high levels of hormones.
Adenomyosis is a condition which develops when the endometrium glands get embedded in the uterine muscle, leading to excessive uterine bleeding.
Using intrauterine devices or IUDs may cause side effects as well.
Several uterine cancers, ovarian cancers and cervical conditions may be responsible as well. Inherited bleeding disorders such as von Willebrand’s disease is another likely cause.
Several medicines and drugs, including NSAIDs and anticoagulants are a common cause.
There are different ways of treating excessive uterine bleeding, depending upon the cause of bleeding and the patient’s age.
Medications: Several medicines are used for the treatment of abnormal uterine bleeding. Hormonal medicines and birth control pills are used to improve the regularity of periods. Non steroidal anti-inflammatory drugs are also used to manage excessive uterine bleeding. Several antibiotics are also used.
Surgery: In many cases, a woman has to undergo a surgery for the removal of polyps and fibroids, which cause excessive bleeding. Certain fibroids are removed via hysteroscopy and other techniques for treatment are used as well. Endometrial ablation can be carried out to manage the bleeding. This treatment aims at permanent reduction of the excess bleeding. Hysterectomy has to be carried out when other treatments are unsuccessful. This is a serious surgery and after it, a woman will no longer have periods, and she will not be able to conceive a child.
In case of excessive uterine bleeding, you must consult a doctor as soon as possible. This will enable early treatment and prevent the development of further complications.
I have a herniated disk (bulged disk/slip disk) at c7 and the c7 nerve is compressed for last 2 months. Do you have treatment in ayurveda ?
I have disc bulge and getting pain in my left leg. I have MRI report my nerve is compressed of left leg.
I have diagnosed with infiltrating ductal carcinoma, NOS, in right breast (in biopsy report. Please suggest me what is my treatment option.
Breast cancer begins when cells in the breast(s) start to grow out of control. It is understood as being the most common cancer, seen predominantly in females, globally. It is reasonably treatable and often curable.
1. Type: Adenocarcinomas constitute more than 95% of breast cancers with infiltrating ductal carcinoma (IDC) being the most common form of invasive breast cancer.
Frequently occurring breast cancers present as one of the following types mainly
1. Ductal Carcinoma In Situ (DCIS): Is the most common type of non-invasive breast cancer and is confined to the milk ducts of the breast. There is no invasion in the basement membrane. Pure DCIS metastasizes rarely. Non comedo cribrioform carcinoma is the most common DCIS found which, when compared to the comedo type, is mostly non-aggressive.
2. Infiltrating Ductal Carcinoma (IDC): Represents majority (about 3/4th) of the breast cancers, and is known to metastasize commonly to bones, lungs and liver.
3. Lobular Carcinoma In Situ (LCIS): Develops in multiple lobules of the breast (bilaterally). LCIS is less commonly seen, compared to DCIS.
4. Infiltrating Lobular Carcinoma (ILC): Represent about a tenth of all breast cancers and tends to metastasize to other regions of the body.
Less commonly occurring breast cancers such as
5. Inflammatory Breast Cancer: Is relatively uncommon and are caused probably owing to viral infections. The breast is warm, red and swollen.
6. Paget’s disease of the nipple: Is a rare form of breast cancer. It begins in the milk ducts and spreads to the nipple and areola.
7. Medullary Carcinoma
8. Mutinous Carcinoma
9. Tubular Carcinoma
10. Phylloides tumor etc all.
2. Gender: Affects the female populace predominantly. However, a small percentage of breast cancer is attributable to the male populace as well.
3. Etiology: No definite cause is known. However, diet, lifestyle, environment, hormonal/ reproductive factors, personal or family history of breast cancer especially in first degree relatives and also any benign breast disease history etc all are known to increase the risk of breast cancers. Specifically, excessive fatty diet, obesity, type 2 diabetes mellitus, benign breast disease, heredity/ inheritance of mutated breast cancer genes 1 (BRCA1) and 2 (BRCA2), smoking, alcohol intake, infertility, estrogen therapy/ hormone replacement therapy (long term) in post menopausal women, delayed age at first pregnancy, nulliparity (not having child), early menstruation, delayed onset of menopause, lactating mothers not breast feeding, exposure to ionizing radiation, sedentary lifestyle, depression, exposure to MMTV virus etc all can potentially increase the risk for breast cancer.
4. Features: Signs & symptoms, of breast cancer, manifest majorly in the following ways
Lump/ nodule in the breast that gets attached to the skin of the breast over time. The lump / nodule could be hard and painless with irregular edges or it could also be soft, rounded, tender and painful.
Enlarged lymph nodes in the axilla which are palpable.
Swelling of whole or a part of a breast. This is even if there is no distinct lump felt.
Retraction or thickening of the nipple(s).
Pain in the breast or nipple.
Discharge from nipple other than breast milk.
Irritation/ scaliness of skin over the breast.
Redness of nipples
Rarely, red, swollen and tender breast.
5. Screening: Is generally recommended for asymptomatic populations goal of which, as usual, is to be able to detect & diagnose breast cancer at an early stage which is potentially curable. It is mostly radiologic with mammography/ USG being instrumental in raising suspicions for further diagnostics (i.e. biopsy) that help detect breast cancer, if any, early.
6. Diagnosis: A self-examination/ clinical exam of the breast(s)/ axilla that reveals a palpable mass prompts the following diagnostics. Abnormal blood test results may be indicative of malignancy, but a follow up imaging/ biopsy is always the gold standard for accurate diagnosis.
- Blood: ER/ PR/ HER2/neu, uPA, PAI-1, CA15-3, CA27.29 etc all tumor markers are helpful.
- Imaging: Mammography/ USG Scan usually, as relevant. Again, CT Scan of abdomen & pelvis and chest, PET CT scan, bone scan etc all help detect metastasis, if any, for cancers in stage III & above.
- Biopsy: either excisional, incisional, fine needle aspiration (FNA) or core biopsy technique, as contextually appropriate, is frequently employed and a histopathological examination (HPE) thereof clinches the diagnosis and the nature of the disease.
7. Treatment: Conventional treatment includes surgery, radiotherapy, hormone therapy/ chemotherapy as deems appropriate. Simultaneously, an adjunctive or integrative naturopathic treatment with suitable complementary & alternative medicines (CAM) too can help improve clinical outcomes and facilitate recovery as would be feasible contextually.
8. Prognosis: Preventive measures, earlier diagnosis and right early treatment is key for an effective therapeutic management & better prognosis. Like most other cancers, the chances of cure for an early stage breast cancer are more. The cure/ recovery chances are influenced by the type, grade, stage of cancer, recurrence and the patient’s general health & vitality etc all. Above-mentioned apart, age, menopause status, lymph node status, ER/ PR/ HER-2/ neu status, size & extent of breast cancer etc all also influence the treatment outlook in breast cancer. The five year survival rate is strongly correlated with the stage of breast cancer.
9. Prevention: Rightly said, prevention is always a better choice. Although genetic risks are difficult to modify, still an increased focus on protective factors and avoidance of the risk factors can be of help. An adherence to a Mediterranean diet, maintaining an ideal body weight and an active lifestyle with due emphasis on regular exercising (for at least 30 minutes daily), de-stressing and relaxation is highly recommended for reducing the risks of breast cancer. A healthy eating plate comprises essentially a low fat diet, fibre rich foods including whole grain cereals, green leafy vegetables cooked using healthy vegetable oils, fresh fruits of all colours as seasonally available and healthy proteins/ fats including fresh fish, poultry, beans, nuts etc all. It is advisable to limit milk/ dairy, preferably of low fat content, to 1 to 2 servings max daily. Although alcohol is optional and is not for everyone, the consumption of the same, if any, has to be strictly in moderation, and is best avoided. Smoking is to be avoided as well. Again, red meat, butter, refined grains, sweets, sugary drinks including carbonated beverages and other high calorie foods etc all, if any, are to be taken sparingly or are best avoided too. Limiting dosage/ duration of hormone therapy, if any, especially to counteract post menopausal symptoms and also avoiding exposure to radiation and environmental pollution can help reduce the risks of breast cancer. Apart from the above-mentioned, for high risk cases, a prophylactic oophorectomy, prophylactic radical mastectomy, long term hormone therapy etc all can help reduce the chances/ risks of developing breast cancer significantly. Breastfeeding is known to confer protection against breast cancer risk too.
What are the alternatives to avoid surgery for my brother aged 47 identified with Listhesis with foot drop and disc extrusion. In fact I had disc bulge (L3 L4 L5) at the age of 41 in 2013 and took oil massage in Kerala for 15 days and I am doing good now.
The symptoms caused due to herniated disc can be very severe and can also cause a bit of disability. The disc of the spine is like a cushion and separates the set of bones on the backside. The discs are shock absorbers of the spine and are mainly composed of 2 parts, a soft jelly-like centre called the nucleus and a tough outer covering called the annulus.
Effects of Herniated Disk
A herniated or cracked disc is a severe condition and it seems to happen most commonly in the lower back or neck. It happens when a fraction of the soft centre gets pushed through the destabilized area due to degeneration, trauma or by putting pressure on the spinal column.
Nerves located at the back of every disc are responsible for transmitting pain, motor impulse, bladder control etc. in our body. While a disc gets herniated, the external covering of the disc tears and creates a bulge. The soft jelly gets shifted from the centre of the disk to the region where the damage has occurred on the disc. Most commonly, the bulge occurs in areas where the nerve is located and it causes strain and irritation of the affected nerve. It has been observed that individuals may or may not feel any painful sensations even if their disc gets damaged. Other symptoms may be weakness of muscle groups or difficulty in controlling the bladder.
When is surgery recommended for herniated disc?
Surgery for herniated disc is recommended only after options like rest and pain relievers do not work. If the pain persists even after these options, then it becomes important to go for surgery. Surgery is also considered early if there is weakness of muscle groups or acute problem in bladder control. At times, emergency surgery is also required to avoid paralysis in a patient.
However, there are certain risks involved in this surgery like infection, bleeding or nerve damage. There are chances that the leftover disc may bulge out again. If you are a patient suffering from degenerative disc disease, then there are chances that problem occurs in other discs. It is very important that a patient maintains healthy weight to prevent any further complications.
The main factor that increases the risk of herniated disc is excess body weight, which causes a lot of stress on the lower back. A few people become heir to a tendency of developing this condition. Even individuals with physically demanding jobs are prone to this condition.
Activities like bending sideways, pushing, twisting, repetitive lifting can increase the risk of a herniated disk. If you wish to discuss about any specific problem, you can consult a Neurosurgeon.
The uterus is a muscular structure held in place inside your pelvis with the help of muscles, ligaments, and tissues. These muscles weaken in women due to pregnancy, childbirth or delivery complications and can lead to severe complications. One such complication is a uterine prolapse. Uterine prolapse occurs when the uterus sags or slips from its normal position into the vaginal canal.
The causes of uterine prolapse are varied and include:
- Delivering a large baby
- Difficulty in labor and delivery
- Reduction in estrogen levels post menopause
- Traumatic childbirth
- Loss or weakening of the pelvic muscle
- Conditions which lead to increased pressure in the abdominal area such as a chronic cough, straining, pelvic tumors or accumulation of fluid in the abdomen
- Loss of external support due to major surgery in pelvic area
Uterine prolapse can be complete or incomplete depending on how far the uterus sags into the vagina. Women who have minor uterine prolapse may not have any visible symptoms. However, if the condition worsens, it manifests itself in visible signs.
Symptoms of moderate or severe prolapse are:
1. A feeling of fullness or pressure in your pelvis when you sit
2. Seeing the uterus or cervix coming out of the vagina
3. Vaginal bleeding or increased discharge
4. Painful sexual intercourse
5. Recurrent bladder infections
6. Continuing back pain with difficulty in walking, urinating and moving your bowels
Without proper attention, the condition can cause impairments in the bowel, and can also affect bladder and sexual function. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
Most commonly known as a military neck a straight or forward curve of the neck is abnormal and may cause an unkind progression of symptoms leading ultimately to cervical disk degeneration.
Reversal of cervical lordosis explained
The anatomy of the neck features a lordotic curvature in its typical and healthy state. This means that the cervical region has a gentle curvature with the open end of that curve facing the rear of the body. The base and top of the curve will be further posterior than the mid point, which will be further anterior.
When the lordosis is straightened, the neck becomes more upright and linear. This is more common than the next progression of atypical curvature, which is the subject of this article.
Actual reversal of curvature means that part or all of the cervical spine develops a kyphotic profile, with the open end of the curve facing anteriorly. Usually, this reversal is extremely mild, but is still very abnormal. What we now see is the middle of the curve being positioned posterior to the top and bottom.
In essence, picture the letter c and now turn it backwards: This is the shape of a reversed cervical lordosis.
Reversal of cervical lordosis causes
The spinal curvature in the neck is constantly in flux to some degree.
Congenital conditions and developmental conditions can have lasting effects on the natural degree of curvature typically demonstrated from patient to patient. These circumstances may be explainable due to injury or degeneration, or may be idiopathic:
Scoliosis can affect the normal lordotic curvature in the neck.
Cervical spondylolisthesis is a major source of reversed lordotic curvature.
Severe disc pathologies can facilitate a gradual loss or reversal of cervical lordosis.
Vertebral irregularities, such as wedging, can definitely contribute to lordotic alteration.
Traumatic injury, including vertebral fracture, can create the ideal circumstances for a reversal of lordosis to take place.
Severe neck muscle spasms can actually reshape the spinal curves, although these are usually temporary expressions and not actual structural conditions.
Effects of reversal of cervical lordosis
The neck is designed to curve in order to balance the spine, absorb stress, distribute force and provide proper movement of the head. When this curvature is diminished or reversed, symptoms may result, although this is not an inherent part of any altered lordotic condition.
Patients may experience stiffness and tension in the neck. Pain may be present and may even be severe in rare cases. Neurological dysfunction is possible in extreme cases, since the neuroforamen might not align properly, thereby causing a cervical pinched nerve.
In the worst circumstances, central spinal stenosis in the neck might affect the viability of the spinal cord, possible enacting the most dire of symptoms throughout the body.
Patients will also be more prone to injury, since the normal shock absorption qualities of the typical curvature have been lost.
While all these effects are certainly possible, they are not usual. In fact, a great majority of patients have minor symptoms or even no symptoms at all from mild reversed lordotic curvatures.
The pathology leading to a neck curve reversal (cervical kyphosis shown below right) may be inspired by a multitude of conditions as follows:
Post head injury
Poor sitting/working postures
Congenital spinal curvatures
Degenerative cervical discs (a form of osteoarthritis that can either be the cause of or the result of a cervical kyphosis)
Compression fracture of vertebral body
Infection of the cervical spine
Anatomy: straight vs. Curved
I've always heard that it was good to stand up straight.
stand upright, stick your chest out and hold your shoulders back! otherwise you're going get widows hump.
Are these expressions as familiar to you as they are to me? one might think that having a curved neck goes against what we heard from parents and teachers as we were growing up, but the reality is that there is a little bit a truth in both. Maintaining good posture throughout our lives is crucial to both the health of our spine and vital organs. On the contrary, a special type of curve called a lordosis is a good thing, both in the neck and lower back.
When we look at a person from the back their spine should be truly straight, so that the left and right sides of one's body is symmetrical. However, when we view a person from the side, the front and back of their body is different and this is reflected in a coinciding curvature of the spine. Both the lower back and neck are hollowed out (concave) and the mid or thoracic spine is protrudes (convex). Thus there is an alternation of curves functioning to provide stability, shock absorption and aid in propulsion. A straight spine would be very stiff and not flexible. Imagine the plight of a pole vaulter with an inflexible pole.
Nature's design of our spine and rib cage facilitates breathing and offers protective and supportive framework for vital organs. Spinal disks are shock absorbers and because they are in the front of the spine, lordotic curvatures keep them from having to bear weight. Kyphosis or loss of such curvatures bears weight upon the disks, leading to their ultimate degeneration. This process of deterioration is a form of osteoarthritis and in the spine is known as degenerative spondylosis.
Although most physiotherapists or conservative orthopedists can recognize a cervical curve reversal upon viewing the patient's posture, a definitive diagnosis may be obtained via a standing lateral (side view) x-ray of the neck. Cause can often be determined by corroborating a comprehensive history, a thorough examination, x-rays and questions about sleep, work and lifestyle.
In my professional career I found that the majority of young adults presenting with cervical kyphosis either had a whiplash or were stomach sleepers from an early age. For desk jockeys 40-60 years of age, many hours of sitting with their head flexed forward almost dictates the fate of developing kyphosis. In prior years I considered cervical kyphosis a job hazard for the careers of accountants, attorneys and often teachers because of years spent with their head in a book or paperwork. However, the digital age offers some relief in that respect. A well-planned, ergonomically-friendly office can do wonders for protecting the spine in the sedentary worker.
Treatment for cervical curve reversal (kyphosis)
During my chiropractic practice I had the opportunity to note a good percentage of correction toward a more normal lordosis (noted on x-ray) for 70% of patients under my care. This was almost always consistent with those patients that followed all recommendations and were model participants in their own care. Here is the recommended treat plan:
Spinal manipulation of stiff and fixated spinal segments by a qualified physio
Flexibility exercises for flexion and extension of cervical spine
Resistance exercises for flexors and extensors of the neck
Learn the Alexander technique for maintaining good posture (hint: the basic philosophy is to sit and stand like you were hanging by a string from the vertex of your skull. Liken it to a puppet on a string).
Elimination of stomach sleeping
Avoid standing on your head, although some yoga postures may be beneficial
Use of orthopedic neck pillow while sleeping.

Lung cancer occurs at slightly younger age in women than in men. Adenocarcinoma is the commonest type of lung cancer in women. It warrants testing for some molecular markers which form the basis of targeted therapies. Thus lung cancer in women behaves biologically and clinically different from that in men

Sir I am suffering from. L4-5 problem since 2 years there is any treatment with out operation please help me.
The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.
Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? it’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
The brain operates on the same amount of power as 10-watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
The human brain cell can hold 5 times as much information as the encyclopedia britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1, 000 terabytes. The national archives of britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.
The brain is much more active at night than during the day. Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
Scientists say the higher your i. q. The more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register.
Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn’t grow or regenerate. While it doesn’t act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.
The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. That doesn’t mean your head can’t hurt. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain and can give you a pounding headache.
80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on tv. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue. So the next time you’re feeling dehydrated get a drink to keep your brain hydrated.
