Thyroid Disease – Causes, Symptoms & Diagnosis

The Thyroid is a gland which is a part of the endocrine system. This gland is in the shape of a butterfly which is situated in the front of the neck with two lobes on either side of the windpipe.

It is connected by a sheat called isthmus which is about 2 inches long. It releases hormones which are used in metabolism.

These hormones regulate the heartbeat, breathing, nervous system, menstrual cycle, body temperature, and many more functions.

The thyroid is a gland which produces, stores and releases hormones into the bloodstream to reach all the cells of the body.

The main produce of the gland is Triiodothyronine(T3) and Thyroxine(T4).

It uses Iodine from the food we take to make these hormones. Hypothalamus and Pituitary gland coordinate to maintain the levels of T3 and T4.

The Hypothalamus produces TSH Releasing Hormone(TRH) to prompt Pituitary to advise Thyroid to release more or less of T3 & T4 when there is an irregularity.

The causes of the Hypo or Hyperthyroidism may be due to

1.Iodine deficiency

2.Defective functioning of the Thyroid gland regulating glands either Pituitary or Hypothalamus or both lumps on the Thyroid gland

3.Medication and so on.

Symptoms of Hypothyroidism


Confusion in the thought process

Feeling cold

Dry skin

Prolonged and excessive bleeding during menstruation



Symptoms of Hyperthyroidism

Intolerance to heat

Sweating profusely

Tremor in the limbs

Increased bowel movement

Increased heart rate

Problems of concentration

Irregular menstrual cycle and so on


To diagnose the disease blood test is performed to check the levels of T3 ,T4, and TSH. If the levels are high it is Hyperthyroidism and if the levels are low it is Hypothyroidism.

In either case, the first line of treatment is oral medication. In hypothyroidism, the hormone is given daily to substitute the deficiency orally. Yoga is also suggested to keep Hypo or Hyperthyroidism under control.
