Are You Gaining Too Much Weight? It Could Be Thyroid Deficiency!


What Is Thyroid Deficiency?

-Thyroid Disorders are very common worldwide and in most of the cases, the problem is an underactive thyroid gland or hypothyroidism. This condition is much more common in women as compared to men.

-Thyroid, a butterfly shaped organ sitting at the base of the throat, produces hormones that regulate the basal metabolic rate which can affect the weight, body temperature and the heart beat.

-Thyroid gets its directions from the hypothalamus and when it receives the signals, the pituitary gland release a hormone TSH into the bloodstream. This hormone acts on thyroid, and causes the release of two hormones, T3 and T4.

How Can Thyroid Deficiency Cause Weight Gain?

-In a person with hypothyroidism, the thyroid gland does not respond to TSH fully leading to decrease in the levels of T3 and T4.

-The most common causes of hypothyroidism are autoimmune disorders like Hashimoto’s Thyroiditis, radiation therapy to the neck, thyroid surgery, too little iodine in the diet etc.

-Patients with underactive thyroid gland have a low basal metabolic rate which leads to a common symptom; weight gain along with difficulty in loosing excess weight.

-Patients with hypothyroidism, may also experience fatigue, increased sensitivity to cold, constipation, dry skin, menstrual irregularities, thinning of hair etc.

How Is It Detected?

The first thing to do if you are experiencing stubborn weight gain is to talk to your doctor regarding the same. He or she may then ask you to perform Thyroid Tests to see the altering levels of hormones such as:

-TSH, that increases in case of hypothyroidism

-T3 or Triiodothyronine, whose levels decrease in case of thyroid deficiency

-T4 or Thyroxine, whose levels also decrease in case of thyroid deficiency
