Excessive Uterine Bleeding - 9 Causes of It!

Excessive Uterine Bleeding - 9 Causes of It!

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:

  1. 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.

  2. Uterine fibroids, which are non cancerous tumours, may lead to prolonged and excessive uterine bleeding.

  3. Polyps are small benign developments on the uterus lining which cause heavy bleeding. They occur because of high levels of hormones.

  4. Adenomyosis is a condition which develops when the endometrium glands get embedded in the uterine muscle, leading to excessive uterine bleeding.

  5. Using intrauterine devices or IUDs may cause side effects as well.

  6. Several pregnancy complications may also lead to excess bleeding. Ectopic pregnancy is a common cause.

  7. 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.

  8. Several medicines and drugs, including NSAIDs and anticoagulants are a common cause.

  9. Medical conditions such as pelvic inflammatory disease, endometriosis, liver and kidney disease or thyroid problems can also cause excessive uterine bleeding.

Treatment:

There are different ways of treating excessive uterine bleeding, depending upon the cause of bleeding and the patient’s age.

  1. 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.

  2. 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.

Brahmi For Brain

Brahmi For Brain

Stress reduction

If the effects of daily stressors are getting the best of you, brahmi supplementation may be something to explore. Stress reduction is perhaps brahmi’s most well known, traditional use. A study evaluating brahmi supplementation reported significant mood improvement among participants, as well as decreased levels of cortisol, the stress hormone. This suggests that brahmi counteracts the effects of stress by regulating hormones involved with the stress response.

Alzheimer’s therapy?

Alzheimer’s disease is a debilitating and heartbreaking disease, usually caused by a plethora of physiological, genetic, and environmental factors. Amyloid formation in neurons can cause significant brain damage and influence the development of alzheimer’s disease. It’s important to understand that, to date, no herb, plant, drug, or anything — including brahmi — has been found to be the magic bullet against alzheimer’s. Based on its history as an herbal therapy to promote neurological function, some have suggested that brahmi may be a promising therapy for alzheimer’s.

Natural Ways to Treat Swollen Legs, Ankles and Feet

MBBS, MS - Orthopaedics

Natural Ways to Treat Swollen Legs, Ankles and Feet

You know that feeling after a long day when your feet are so sore or swollen that you can’t bear the thought of standing on them for any longer? once you take off your shoes and sit down, or even soak them in a warm bath, it’s still an unpleasant experience. Luckily, I’ve collected 10 natural remedies for such an occasion and I want to share them with you.
 
Important: regular swelling vs potential health risks
When experiencing swelling in the feet and legs, apply pressure to the area with a finger. If the dimple created by the finger remains for more than a couple of seconds, it may indicate oedema, which can be the result of heart, liver, or kidney problems. When this occurs, see a doctor at the first possible opportunity.
If you experience swelling in one leg but not the other, you should also see a doctor as this may be an indication of deep venous thrombosis (a blood clot blocking the blood vessels).
If the swelling is accompanied by shortness of breath, fever, bluish skin, and chest pains, get immediate medical attention.
 
10 natural remedies:

1. Soak your feet in epsom salts
Pour 250g of epsom salt into a hot bath, and take a nice long soak. You can also add essential oils to the mix for enhanced relaxation. Your feet will thank you, your body will thank you, and you’ll emerge from that bath a happier person.
2. Massage the area
Massaging the painful area increases blood flow and moves the fluids that accumulate and cause the swelling. If you want to indulge, get someone to massage your feet for you, preferably with hot essential oils.
3. Stop smoking
If you smoke tobacco (cigarettes, cigars, etc.), you should know that one of the many negative effects of nicotine is constriction of blood vessels, which can lead to sore feet.
4. Stay hydrated
When the caffeine and sodium we consume accumulate in the body, they can cause swelling and pain in the limbs. The best way to dilute them and flush them out is by drinking water. If you want to maximize the efficiency of hydration, squeeze a lemon or lime into the glass of water for a boost of vitamins and antioxidants.
5. Eat healthy, avoid excess salt
While we need salt for our body to function well, when we overdo it, it can have adverse effects. Reduce the amount of salt you consume every day, and consider cutting down on caffeine as well.
6. Elevate the legs
If you’re suffering from chronically sore legs/feet, try keep your legs elevated for 30 minutes, three times a day. You will notice a difference within a couple of days. Also, when you’re in bed, use a couple of pillows to prop up your feet. Elevating the legs helps to drain the excess fluids that causes the swelling and pain.
7. Avoid sitting for prolonged periods
Whether you’re flying, taking the bus, or just sitting in an office all day, keeping your legs stationary can lead to pain and swelling. If you know you’re going to sit for a long period of time, make sure to stand up, stretch, and walk around every 20 minutes or so.
8. Use compression socks when traveling
If you’re going to fly overseas, another excellent solution is to use compression socks. These socks apply pressure to your feet, preventing fluid from building up – the main cause of swelling and pain in the feet.
 9. Exercise
Exercise will help boost your cardiovascular system, which in turn will reduce the possibility of swelling in the limbs. Exercise increases blood-flow in the body and reduces weight. 
10. Take magnesium supplements
Magnesium is essential for our body’s function. That said, many people suffer from a magnesium deficiency. By adding magnesium to your system, you will improve your overall health, reduce hangover symptoms and suffer less pain in your extremities

I am having slip disc. I want to know to cure it with exercises and what are the precautions to took for this?

Till you have pain, exercises would have little help. Initially you have to take bed rest. Avoid forward bending & cross-legged sitting on ground. Sit with a straight back. You can wear l. S. Belt temporarily. When pain subsides you can start exercises as guided by your doctor to prevent future disc problems.

ECMO New Era of Medicicne

Homeopath,
ECMO New Era of Medicicne

What is ECMO?
Like dialysis for unfunctional kidney, Ecmo for unfunctional lung.

Ecmo stands for extracorporeal membrane oxygenation. It is a method of giving oxygen for the body when icu pateint lungs and/or heart are not able to supply oxygen on their own. 

Why ICU pateint put on ECMO?

Doctors place ICU patients on ECMO when patients are not able to supply oxygen to the body.

ICU patients’ lungs fail for a number of reasons including pneumonia, lung cancer, pulmonary edema, pulmonary embolism and COPD.

 When a patient’s lungs fail, he/she first is intubated (breathing tube) and hooked up to a ventilator (breathing machine).
 However, sometimes lungs are so damaged that providing oxygen through intubation is not enough.

This is when doctors turn to v-v ecmo.
A heart can fail for many reasons including heart attack, pulmonary embolism, bad valve disease, or worsening heart failure. When a heart fails, doctors try to fix the underlying problem. They may also start medications (called ionotropes) to help improve the pump function of the heart. If medications are not enough, doctors will turn to v-a ecmo.

How long can someone stay on ecmo?

That is a complicated question. Due to the risks of ecmo discussed above, doctors try to keep patients on ecmo for as short a time as possible. Often patient will be on ecmo for several days up to 1-2 weeks. Every day, several blood and imaging tests are done to determine if a patient is ready to come off ecmo. As the technology of ecmo improves, hopefully side effects will decrease and patients can remain on ecmo for longer periods of time.

What is the difference between ecmo and a ventilator (breathing machine)?

Both ecmo and a ventilator aim to provide oxygen to the body when the patient’s own lungs and breathing are failing. The ventilator assists the patient’s own lungs by pushing oxygen with pressure into the lungs. Ecmo instead provides oxygen directly via a catheter placed in a patient’s vein or artery. We almost always try oxygenating a patient with a ventilator first. However, when a patient’s lungs are too sick for this, we turn to ecmo to assist in providing oxygen to the body. V-v ecmo provides oxygen through a vein. This blood then has to travel to the heart and be pumped around the rest of the body through arteries. Therefore, with v-v ecmo or with a ventilator, a patient must have a well-functioning heart to get the oxygen pumped throughout the body. V-a ecmo has the additional advantage of pumping blood directly to arteries. This “by-passes” the heart and is therefore the method of ecmo we use when a patient’s heart is failing.

How Is Breast Cancer Diagnosed?

MBBS, MD - Obstetrtics & Gynaecology
Gynaecologist, Delhi
How Is Breast Cancer Diagnosed?

Breast cancer is a form of cancer which develops from the breast tissue. Breast cancer is indicated by signs such as a lump in the breast, changes in breast shape, fluid flowing from the nipple, dimpling of skin, or the development of red scaly patches. Breast cancer is a fatal form of cancer in women and immediate diagnosis is required on observing the symptoms.

Diagnosis of breast cancer
Other than the regular breast screening, the diagnosis of breast cancer involves the following steps and methods:

  1. Seeing your general practitioner (GP): It is very important to visit your GP soon after noticing the symptoms of breast cancer. Your GP will examine you properly and in case your symptoms need more assessment, he/she will refer you to a breast cancer clinic.
  2. Mammogram and breast ultrasound: You will be required to have a mammogram, as recommended by a specialist breast unit. This is an X-ray of the breasts. An ultrasound scan may also be required. Breast ultrasound should be undertaken only if you are less than 35 years of age. This is because, young women have denser breasts and a mammogram is not as effective as ultrasound in the diagnosis of breast cancer. In ultrasound, high frequency sound waves are used for obtaining an image of your breasts. It is observed to notice any abnormality or lumps. A breast ultrasound is also important for determining whether a lump is solid or contains liquid.
  3. Biopsy: In this diagnosis process, a sample of the tissue cells is taken from the breasts and tested under a microscope to find out if it is cancerous. A scan and needle test for the lymph nodes present in your armpit is also done to check whether they have also been affected. A biopsy is undertaken in several ways, depending upon the condition and severity. A needle aspiration biopsy is used for testing a sample of your breast cells without the removal of the tissues. This is the most common form of biopsy and it is also used for draining a small fluid-filled lump or benign cyst. During the process, you will be given a local anesthetic. Usually, a needle biopsy is carried out guided by an X-ray, ultrasound and an MRI scan as well. This helps in distinguishing it from non-invasive changes such as ductal carcinoma in situ.

Another form of biopsy used for the diagnosis of breast cancer is called vacuum assisted biopsy or mammotome biopsy. In this process, a needle gets attached to a suction tube, which helps in obtaining the sample and for clearing the bleeding. If you wish to discuss about any specific problem, you can consult a general-surgeon.

Causes and Symptoms of Ewing's Sarcoma

European Society for Medical Oncology certification, DM - Oncology, MD - General Medicine, MBBS
Oncologist, Faridabad
Causes and Symptoms of Ewing's Sarcoma

Collectively grouped under the Ewing sarcoma family of tumors, Ewing's sarcoma is the second most common form of bone cancer, which is commonly seen in children and adolescents. Very rarely is it experienced in adults above the age of 30.

Typically forming in the bones of the chest, pelvis, head, back or trunk and in the long bones of the arms and legs, Ewing's sarcoma is believed to originate in certain kinds of primitive cells. When it begins to affect similar kind of cells found outside the bone, it is usually called an extraosseous Ewing's sarcoma.

Causes
1. Similar to all types of Ewing tumors, Ewing's sarcoma is generally caused by an alteration in a certain cell compelling a gene named EWS found on chromosome no. 22 to move over to a DNA section on any one of the surrounding chromosomes resulting in the activation of the EWS gene.
2. While it is not a hereditary condition, it usually occurs after childbirth, but no substantial evidence has been found as to why it happens so.

Symptoms
Symptoms of Ewing's sarcoma may include:
1. Swelling and pain especially in the arms, legs, back, chest or pelvis
2. Swelling accompanied by joint immobility
3. A bone breaks having no apparent cause
4. Swelling which may or may not be accompanied by a warm, tingling sensation
5. Fever resulting from unknown causes
6. Lumps or bumps which do not subside over time
7. Abnormal weight loss
8. High levels of fatigue
9. Tumors which have spread over to the lungs may cause shortness of breath
10.Tumors spread over to the spine may cause weakness or even paralysis.

Because the symptoms of Ewing's sarcoma can hardly be distinguished from symptoms caused by other infections or injuries, an early diagnosis is absolutely necessary for a successive treatment. If you wish to discuss about any specific problem, you can consult an oncologist and ask a free question.
