Question 1

What is the thyroid gland?

Accepted Answer

The thyroid is a butterfly-shaped gland in the neck that produces thyroid hormones T3 (triiodothyronine) and T4 (thyroxine). These hormones regulate metabolism, energy, heart rate, temperature, and many other body functions.

Question 2

What is hypothyroidism?

Accepted Answer

Hypothyroidism occurs when the thyroid gland produces less T3 and T4 than the body needs. As a result, the pituitary gland releases more TSH (Thyroid Stimulating Hormone) to signal the thyroid to work harder. A high TSH with low T3/T4 confirms hypothyroidism.

Question 3

What is hyperthyroidism?

Accepted Answer

Hyperthyroidism occurs when the thyroid gland produces excess T3 and T4. The pituitary gland responds by reducing TSH production. A low TSH with high T3/T4 confirms hyperthyroidism.

Question 4

What are the symptoms of hypothyroidism?

Accepted Answer

Common symptoms include dry skin, persistent fatigue and lethargy, mood swings, menstrual irregularities, constipation, weight gain, excessive sleepiness, and significant hair fall.

Question 5

What are the symptoms of hyperthyroidism?

Accepted Answer

Common symptoms include excessive sweating, palpitations (fast heart rate), unexplained weight loss, frequent loose stools, irritability, restlessness, menstrual irregularities, and difficulty sleeping.

Question 6

What causes thyroid disorders?

Accepted Answer

Most thyroid disorders are autoimmune in origin — the body's immune system attacks the thyroid gland. This results from a complex interplay of genetic predisposition and environmental triggers. Women are significantly more likely to develop thyroid disorders than men.

Question 7

Does food intake affect thyroid?

Accepted Answer

No specific food causes autoimmune thyroid disorders. Severe iodine deficiency can cause goiter. Very large amounts of raw cruciferous vegetables (cabbage, broccoli, cauliflower) may slightly interfere with thyroid hormone production in susceptible individuals.

Question 8

Is thyroid disorder curable?

Accepted Answer

In the majority of cases, thyroid disorder is a permanent condition requiring lifelong medication. In rare cases (such as thyroiditis during pregnancy or postpartum), the condition may be transient.

Question 9

Why is it important to treat thyroid disorders?

Accepted Answer

Untreated hypothyroidism can lead to heart disease, high blood pressure, elevated cholesterol, persistent mood disturbances, and significantly reduced quality of life. Untreated hyperthyroidism can cause heart rhythm problems and bone loss.

Question 10

How is hypothyroidism treated?

Accepted Answer

With synthetic levothyroxine (T4 tablet). The dose is titrated based on TSH levels checked every 6–8 weeks until stable. The tablet must be taken on an empty stomach, at least one hour before breakfast or tea.

Question 11

How is hyperthyroidism treated?

Accepted Answer

Hyperthyroidism is treated with antithyroid medications (carbimazole or propylthiouracil), radioiodine therapy, or surgery — depending on the cause and severity. Regular monitoring of thyroid hormone levels is essential.
