AV or arterio-venous fistulas are unusual linkages between arteries and veins. In general, pure blood passes from the arteries to the capillaries to the veins and becomes devoid of nutrients and oxygen (becomes  impure ) by the time it reaches the veins. The capillaries in between absorb the nutrients, to supply them to the tissues and organs lying beneath them. In the case of AV fistulas, the capillaries are bypassed and blood passes directly between the arteries and the veins. Thus, organs are deprived of nutrients.

This can be a severe condition, leading even to heart failure.

AV fistulas and dialysis

Sometimes, AV fistulas have to be deliberately created on the body, to treat for severe kidney ailments requiring dialysis.

What is the surgical procedure for creation of AV fistulas for dialysis?

Following are the steps-

  A vascular specialist checks your arteries and veins to make sure they are sturdy enough to be able to support an AV fistula.
  Then, with the help of wave techniques or an angiogram, the depth of your blood vessels is recorded.
  Anaesthesia is then used on the spot, which is chosen for your AV fistula. Local anaesthesia (anaesthesia of only that spot) is preferred over central anaesthesia (anaesthesia of the whole body).
  With the help of a small cut on the skin surface, the surgeon accesses your blood vessels and makes a connection between arteries and veins.

After this process is completed, dialysis takes usually some weeks to begin.

Why should you go for AV fistula?

Following are the advantages-

  Foreign chemicals or devices, which may cause invasion and damage to vital internal organs, are not introduced in your body.
  As only local anaesthesia is administered, you have to spend significantly less recovery time or  downtime  after surgery.
  There is less chance of the wound becoming infected.
  There is a reduced danger of clotting.

AV fistulas are in essence an unusual connection between your arteries and veins, leading to undernourished organs due to capillaries being bypassed. In some cases like dialysis, AV fistulas need to be created and closely monitored. There are several advantages to this, but you will also need recovery time after the procedure is over.

AV Fistula - Its Surgery & Creation Of AV Fistula For Dialysis!

 Thyroid is a small gland situated in front of the neck and secretes hormones like thyroxine (T4) and tri-iodothyronine (T3). These hormones control various functions of our body like heart, blood pressure, digestion, metabolism, growth, blood formation, brain function etc. Any fluctuation in the functioning of the thyroid gland can have a great impact on health. The thyroid gland is primarily responsible for energy and metabolism. This gland triggers the genes that make all the cells in the body conduct their specific jobs. But over a period of time, the optimum functioning of the thyroid may reduce because of specific reasons. The gland may start to under-produce or overproduce the thyroid hormone, which may lead to conditions known as hypothyroidism or hyperthyroidism, respectively. 

Patients with hypothyroidism may feel extreme tiredness and fatigue even though they may be sleeping more than before. An unexplained gain in weight, constipation, inability to stand cold temperatures, and constant pain in muscles and joints are some of the other symptoms of hypothyroidism. 
Hyperthyroidism, or overactive thyroid, is an endocrine disorder. Patients with this disorder may experience excessive sweating, fatigue, and intolerance to heat. They may even experience restlessness, puffy or protruded eyes, hair loss, and muscle weakness. Such patients may lose weight and are unable to sleep properly at night. In some cases, palpitations or abnormal heart rhythm may also be experienced. 
Complications of Thyroid Disorder 

Hypothyroid and hyperthyroid can cause a number of complications if patients don t take medications. It is important for you to not to ignore any of the aforementioned symptoms and speak to your doctor as soon as possible. 

Hypothyroid complications

Myxedema: This condition is characterized by slowed thinking, swelling of tissues, and accumulation of fluid around major organs like brain, lungs and/or heart. This condition may prove life-threatening if not treated on time. 
Enlarged goiter: This is characterized by enlargement of the thyroid gland because of a constant increase in the TSH levels. High cholesterol and triglycerides: This may eventually pave way for heart disease and stroke. 
Sleep apnea: Sleep apnea is a disorder that affects nighttime breathing where the brain that temporarily stops sending signals to the muscles that control breathing, or by an obstruction in the airway. This may prove fatal if left untreated. 
Low blood pressure: This means not enough blood is getting to capillaries and tissues, particularly in your hands, feet, and brain. You may have chronic nail fungal infections and cold hands and feet if so. 
Hyperthyroid complications 

Heart disorders (cardiac arrest): If left untreated, excess thyroid hormones can lead to congestive heart failure and heart rhythm disorders. 
Osteoporosis: Too much thyroid hormones interfere with the body s ability to use calcium to build bone. This may lead to brittle bones and osteoporosis. 
Thyrotoxic crisis: This is a rare yet life-threatening complication characterized by high fever, vomiting, irregular heartbeat, and agitation. 
Hypertension or high blood pressure: It is a condition in which a patient has high blood force striking the walls of the artery An early diagnosis can help make the treatment of this disorder easier. 
Depending on the condition of the thyroid condition, it requires different ways to manage it. The conventional TSH (thyroid-stimulating hormone) and T-4 (thyroxine) blood tests will be advised and the results should provide a reasonable confirmation of the condition. If doubts still persist an ultrasound or scan can also be ordered. In case you have a concern or query you can always consult an expert & get answers to your questions!

Is Your Thyroid Gland Working Against Your Body? 

What you eat plays an important role while you are udergoing thyroid disorders. Certain nutrients can influence the functionalities of the thyroid gland, while some foods can prevent the body s ability to absorb the hormones to a substantial extent. As with a lot of health conditions, some factors are not in our hands which include family history and the environmental factors around you. However, the factor that you can control, is diet.

You can empower yourself to choose a healthier lifestyle through the right diet. It is advisable that you choose your foods wisely. Some of the following foods are known to be beneficial in managing thyroid:

1. Yoghurt
You will be happy to know that dairy products can contribute to fulfilling the much-needed iodine requirement of your body. Since livestock are generally given copious amounts of iodine supplements and the process of milking incorporates iodine-based cleaners, you can get plenty of iodine from dairy products, particularly, yoghurt. Greek yoghurt is one of the prime sources of iodine and can make up to about 50 percent of the daily intake of the nutrient.

2. Seaweed
When suffering from thyroid, you need iodine to function properly. Producing adequate levels of the thyroid hormone is important to fulfil the needs of the body. Though taking iodized salt can help a lot in your daily iodine intake, you can take additional aid from seaweed. It is important to understand that taking too much iodine can trigger the symptoms of hypothyroidism and the trick here is to balance out how much your body needs.

3. Milk
Much of the iodine in one s diet comes from dairy products. When you drink about 1 cupful of low-fat milk, you can effortlessly consume around 1/3rd of the daily iodine requirement. It would be better if you take milk rich in Vitamin D. If you are neither a fan of milk nor yoghurt, you may also resort to cheddar cheese, as a single slice can give you around 12 micrograms of the much-needed iodine.

4. Chicken
While all the hype is about iodine, zinc also plays an important role in controlling thyroid symptoms. When you take too little amount of zinc, you can get hypothyroidism and in case you already have this condition, your body will need it more since the thyroid hormones help in the absorption of the minerals. Meat, particularly chicken is an amazing source of zinc when you have it roasted.

5. Fish
Fish is yet another source of iodine since it is found in sea water as well as in soil. Taking 3 ounces per serving of baked cod fish can give you around 99 micrograms of iodine. Moreover, shellfish, lobster, and shrimp are good sources of iodine as well.

By adding these foods, you can definitely control your thyroid symptoms to a considerable extent. Controlling your diet is the key to managing your thyroid condition, and therefore you must pay special attention to it.

Diet Tips For Managing Thyroid!

The gallbladder can be found under the liver and is a pear shaped organ. This four inch organ is responsible for storing bile, which is a combination of the various fluids as well as fat and cholesterol. These are essential for the body and its metabolism, as the bile helps in breaking down the food that enters the digestive system. With the help of the gallbladder, this bile divides the food into smaller parts within the intestine. This ensures that the energy released by the food is more easily absorbed into the bloodstream. There are a host of problems that can attack the gall bladder including stones, infection and more.

Let us find out the symptoms of a gallbladder attack and the various ways in which it may be successfully treated.

    Pain: One of the most common symptoms of a gallbladder attack includes pain. This can be felt in the section that lies in the middle and the upper right portion of the abdomen. The patient may initially experience mild pain that comes and goes intermittently. Eventually, if the pain is not treated, it can start to radiate on a constant basis and hold the patient in its grip.
    Nausea: Nausea and vomiting are also common symptoms of any gallbladder related problem. Chronic cases usually end up experiencing these symptoms. Nausea and vomiting in such conditions are a result of digestive problems like acid reflux which can be caused due to the gall bladder condition.
    Fever: If there is an infection in the gall bladder, then the patient may also experience fever and chills. This will require immediate treatment and the prescription of antibiotics. If it is not treated on time, the problem can become serious and dangerous.
    Loose Motions: Diarrhoea is a problem faced by many patients suffering from this condition along with jaundice and lighter coloured stools.

Treatment: Mostly, doctors will recommend surgical methods to deal with gall bladder attacks and conditions. A laparoscopic surgery may be conducted to remove the gallbladder. Also, medication will be prescribed to dissolve the gallstones that may have been caused by cholesterol. The patient will also have to undertake many lifestyle changes in order to successfully treat this condition over a period of time.

One will have to avoid greasy and oily food. Also, the fat intake of the patient will have to be reduced so that the cholesterol build up does not affect the gallbladder again. The patient will also have to add fibre to his or her daily diet, in the form of fruit and oats. This will help in improving the bowel movements as well.

The Symptoms and Treatment of Gallbladder Attack

There are glands inside the anus that secrete fluids. Sometimes these glands can get clogged. Pus builds up in the blocked clogs, which get infected. This is called an abscess. Unless the abscess is treated right away, it will keep growing. It eventually punches a hole through the skin near your anus to drain the infected tissues and pus. This tunnel that leads from the gland to the hole is called a fistula.

Usually, it is an abscess that causes a fistula. But sometimes a fistula can be caused by tuberculosis, a bowel illness or sexually transmitted diseases.

What are the symptoms of anal fistula?

The symptoms of anal fistula are-

  Pain while sitting down
  Soreness around the anus
  Swelling and redness
  Bleeding
  Painful defecation
  Fever
  Foul secretion from a hole near your anus

How is fistula diagnosed?

If you complain of any of the above symptoms, a doctor will perform a physical examination on you.

Sometimes a physical examination does not reveal a fistula because the fistula can close for a while and then open up again. So then your doctor might ask you to get the following tests done-

  A blue dye test
  Computerized tomography (CT Scan)
  Anorectal ultrasound
  Colonoscopy.

Treatment for anal fistula

Unfortunately, there are no medicines that can treat fistula. If you are diagnosed with fistula, you will require surgery. However, it is a minimally invasive surgery with no risks involved.

The surgery is performed under general anaesthesia. A fistula surgery can be done in the following ways-

  If the fistula is located beneath the sphincter muscles, the surgeon cuts the fistula open so that it can heal and new healthy tissues can develop there.
  If the fistula passes through the upper part of the sphincter muscles, then the surgeon runs a special stitch through the fistula (seton stitch) so that the fistula can drain properly and heal. It takes 6 weeks for the pus to drain and the wound to heal
  Sometimes, a doctor will simply plug the fistula so it does not seep pus.

General and specific complications of a fistula surgery

Though it is a safe surgery, some complications may arise, but rarely. These may be general or specific.

General complications-

  Bleeding and pain
  Scarring around the region of the surgery

Specific complications-

  Pain while urinating
  The involuntary passing of wind or lose faeces

An anal fistula is a painful condition that refuses to go away and the only way to cure it is surgery.

Can Medication Treat Anal Fistula? Find Out!

Do you feel extremely tired many times in a day? Are you experiencing sudden weight gain, chills at night and hair loss? Is your neck a bit bloated up? If you are experiencing any of the mentioned symptoms, it might be that your body regulator- Thyroid- is unbalanced. Quick 3 tests can help you detect any abnormality - TSH, T3 and T4. Women were three times more likely to be affected by thyroid dysfunction than men. 1 in 10 adults in India suffers from hypothyroidism, with 50 per cent being women.

What is the thyroid gland?
The thyroid is a butterfly shaped gland in the front of the neck. It produces hormones that control the speed of your metabolism - the system that helps the body use energy. Thyroid disorders can slow down or rev up your metabolism by disrupting the production of thyroid hormones. When hormone levels become too low or too high, you may experience a wide range of symptoms.

What are the Symptoms?
Thyroid can be of 2 types - Hyper (Overactive) and Hypo (Underactive) Thyroid.
Low and Underactive Thyroid High and Overactive Thyroid
Fatigue Nervousness
Dry Skin & Hair Tremors - Hand Shaking
Brittle Hair Hair loss or thinning hair
Constipation Diarrhea
Low Pulse High Pulse
Weight Gain Weight loss without trying
Intolerance to cold temperature Intolerance to hot temperature
Depression Sweatiness
Swelling in lower part of neck Swelling in lower part of neck

The swelling in the neck is a major and most significant feature. Hence one should always do the Self Neck Test.

Who should be tested?
Women aged 35 and above or those with symptoms/risk factors/family history are the right candidates for screening. It has been estimated that 75% of the people suffering from thyroid are undiagnosed.

Diagnosing thyroid disorders - A simple blood test can provide an answer. TSH (Thyroid Stimulating Hormone) levels determine thyroid hypo and hyper function as it regulates the work of thyroid gland. Rarely an imaging study or biopsy is needed. Two additional tests may be required - T3 and T4.

What happens if Thyroid remains undetected?
As Thyroid disorders are hormonal imbalances, undetection can lead to a number of secondary complications:
Obesity
High Cholesterol and Hypertension
Hair Fall
Heart Disease
Complications in pregnancy
