T3 Reverse Test

T3 Reverse Test

also known as: T3, Reverse

T3 Reverse test is an automated blood test to measure the level of T3 Reverse in blood. It is performed to confirm whether Hyperthyroidism and Hypothyroidism are present. This test is also helpful during and after the treatment of Hyperthyroidism and Hypothyroidism. Also commonly known as Reverse Triiodithyroinine Blood or Reverse Triiodithyroinine. Generally, increased levels of T3-R have been found in the cases of starvation, anorexia- nervosa, severe trauma and hemorrhagic or shock, hepatic dysfunction, postoperative states, severe infection, and in burn patients.

Make sure to wear a short-sleeved shirt or a shirt with sleeves that you can easily roll up.No special preparation needed for the T - 3 reverse blood test. There’s no need to adjust your diet. You can both eat and drink normally.However, your doctor may require that you fast for a specific amount of time before the test. That’s common if the blood sample is required for additional testing. Your doctor will give you specific instructions.

The normal result obtained for T3 Reverse is T3 Reverse found between 10 - 24 ng/dL for unisex gender and for all the age groups. The T3 Reverse is seen high in patients on the following medications: propylthiouracil, ipodate, propranolol, amiodarone, dexamethasone, and the anesthetic agent halothane. Dilantin decreases T3 Reverse due to the displacement from thyroxine-binding globulin, which leads to an increase in T3 Reverse clearance. In hospitalized or sick patients with low triiodothyronine (T3) values, increased reverse triiodothyronine (rT3) values are seen normally with "sick euthyroid" syndrome.

During this test, a lab technician will draw blood from a vein, generally
from the inside of your elbow.
The lab assistant will:
1.clean your skin with an antiseptic wipe. an elastic band around your upper arm to help the vein swell
with blood.
3.insert a needle in the your and collects the required amount of blood.

5.label your sample and send it to a lab for analysis.

Dear user. I understand. The higher rates according my opinion is fatty liver. Because nowadays people are less to do sport and like to eat fastfood, while on fastfood there were high cholesterol and if body difficult to convert it. The cholesterol will circulate around your body through the blood. So on the lab test the lipid profile show high level (high LDL, trygliseride, and total cholesterol. But low HDL). LDL was bad cholesterol, while HDL is a good cholesterol. If the cholesterol to much in our body it can be deposit through all your body but if the lipid deposit in your liver it can cause fatty liver. Fatty liver is a condition where the surface and inside your liver cover by lipid. Sometimes lipid can kill the healthy liver cell, so that makes lab test for SGOT and SGPT increased. Exercises and food control can reverse the fatty liver condition. Talk to your doctor. Take care.

Know The Ayurvedic Approach To Reversing Diabetes!!

Know The Ayurvedic Approach To Reversing Diabetes!!

Glucose is the primary ingredient within the body which is turned into an energy source. This is what we use when we move, walk or make the slightest movements. To metabolize glucose into energy, your body needs insulin, which is a hormone produced within the pancreas. However, if the body doesn't react to the insulin or the pancreas is unable to produce enough, glucose cannot be converted into energy and thus results in type 2 diabetes.

Symptoms of type 2 diabetes

  1. Sudden or gradual weight loss despite increased hunger - Many people complain that they feel hungry and eat more, but despite this, tend to lose weight. This occurs as the body cannot metabolize glucose and uses energy reserves from fat or muscles leading to weight loss.
  2. Frequent infections and slow healing - If you are afflicted with Type 2 diabetes, then it might affect your immune system and you may be prone to infections. Also, any cuts or bruises on your body will take much longer to heal than normal.
  3. Irritability and fatigue - Another common symptom of type 2 diabetes along with the other symptoms mentioned here is quick irritability and fatigue. This is because most of the body is deprived of sugar and thus lacks the energy needed to function normally. 
  4. Constant thirst and increased urination - If you feel constantly thirsty despite drinking ample water and urinating frequently, this may be a tell tale sign of type 2 diabetes.
  5. Skin darkening in folds and creases of the body - Also known as acanthosis nigricans; this is a darkening of the skin where it also becomes velvety to the touch. It usually develops in the folds on skin in areas such as the neck and armpits and is a direct result of insulin resistance.

Causes of Type 2 diabetes

Some of the most common causes of Type 2 diabetes could be:

  1. Being overweight
  2. Lack of physical activity
  3. Genetic predisposition or family history 
  4. If you are more than 45 years of age
  5. Hormonal problems such as Polycystic ovarian syndrome

Reverse Diabetes

There three major factors that can help you prevent and reverse pre- and type II diabetes: proper diet and appropriate nutritional and herbal supplementation, exercise, and weight management.

  1. Diet: Proper diet is critical for both preventing and treating pre-and type II diabetes. One of the most important dietary precautions you can take is to eliminate all refined sugars and sugar products from your diet. Also reduce or eliminate your intake of alcohol and caffeine; avoid fast, processed "junk" foods and soda, altogether; and eat protein snacks between meals.
  2. Eating According to the Glycemic Index: Another important dietary tip is eat meals that contains an abundance of low-glycemic (low-sugar) foods. By doing so you can significantly improve your body's ability to maintain low insulin and blood sugar levels. Low-glycemic foods include raw, organic leafy green vegetables, fruits that contain pits, sweet potatoes, yams, organic whole-grain breads and cereals, most legumes and nuts, skim and buttermilk, poultry, white fish, shellfish, and lean cuts of beef and veal.
  3. Nutritional and Herbal Supplements: In addition to a healthy diet, many people at risk for or who already have pre- or type II diabetes will also benefit from various nutritional and herbal supplements.
  4. Exercise: Regular exercise should be part of every diabetic's daily routine. Exercise in combination with a weight loss program has been proven to reduce the odds of developing diabetes by 58 percent among people who are at risk for the disease. If you wish to discuss about any specific problem, you can consult with the doctor for diabetes ayurvedic treatment.

How To Deal With Phobia Of Genetic Sexual Attraction?

In the realm of sexual relations, Incest is one of the longing social taboos. In order to curb this social taboo, many governments have introduced law banning incest. Basically, this is a sexual relationship between those who are blood-related, which is also called as Consanguineous relationship. This is also called as Genetic Sexual Attraction (GSA) which can be between siblings, half siblings, donor children, adoptees, biological mother and father, nephew and so on. This is a social evil, and experts have some remedies so that you can deal with genetic sexual attraction.


According to an article published in Spanish Magazine AFIN in July 2013, separation of siblings for quite a long time is one of the known causes for genetic sexual attraction. At the same time, the magazine points out that there are instances that even those who are not separated have this mania of genetic sexual attraction. Some of the other interesting aspects of GSA can be explained as follows:

  1. It is said that children who grow in close proximity since their childhood develop reverse sexual attitude or imprinting with their siblings, parents and with other consanguineous relationships. This reverse sexual attitude actually suppresses sexual desire with consanguineous relationship. This theory is also called as Westermarck Effect. This can be the pointer to the question How to deal with Genetic Sexual Attraction because consanguineous relationship separated for years may not have the Westermarck Effect.

  2. It is pointed out that when siblings who are separated for long duration of time are sexually mature when they meet each other. In other words, they were not members of the nuclear family, and this long absence can attract each other for a closer relationship. In addition to this, the siblings are biologically and mentally so grown up that they have made their own hard imprint of their character, taste and so on. It is a combination of these factors that makes them an exception to the Westermarck effect.

Symptoms of GSA:

Extreme awareness about the other person, hard desire to stay or talk, distractible behavior, unnecessary talking, holding hands or touching or making use of every opportunity to have some kind of physical contact, daydreaming are some of the known symptoms of GSA.

Remedy Available:

One of the ideal remedies for those suffering from GSA is to seek help of appropriate medical fraternity in the earliest possible time. This is one of the most ideal approaches to deal with genetic sexual attraction. It is also suggested that you should ensure that the siblings meet at regular intervals. This can help the siblings to have Westermarck Effect. If you wish to discuss about any specific problem, you can consult a Sexologist.

Can Heart Attack Damage Be Reversed?

DM - Cardiology, MD - General Medicine, MBBS

Can Heart Attack Damage Be Reversed?

A heart attack occurs when the flow of blood to the heart is blocked, often by a buildup of fat, cholesterol, and other substances, forming a plaque in the arteries. If blood flow is not restored quickly, the section of heart muscle begins to die, starving for oxygen. This causes a heart attack. A heart attack can also be caused by the rupture of the coronary artery. During a coronary rupture, the coronary arteries get restricted, reducing blood supply to the heart muscle.

Each coronary artery supplies blood to a region of the heart muscle.

Extent of damage to the heart muscle depends on the area supplied by the blocked artery and time between injury and treatment. Making some changes in your diet; how consistently you exercise; how much you weigh and how you manage stress can help you to recover from a heart disease quickly.

You can undo some, but probably not all of the damage, if you're willing to make big and lasting changes to your lifestyle. To reverse the impairments caused by a heart attack/disease you can become a vegetarian. Filling your platter with fruits and vegetables, whole grains, soy products, non-fat dairy and egg whites while avoiding fat, refined sugar and processed carbs is a sure-shot way of keeping your heart healthy and preventing future attacks. If you wish to discuss about any specific problem, you can consult a Cardiologist.
