Question

Non-toxic goiter is seen in the case of
(a)Hypothyroidism
(b)Hyperthyroidism
(c)Both A and B
(d)None of these

Answer 1

Hint: Nontoxic nodular goiter is the enlargement of the thyroid gland associated with reduced production of the T3 and T4 hormones. It often appears years before a toxic nodular goiter occurs.

Complete answer:
Non-toxic goiter is a common condition seen in the case of hypothyroidism and is related to a deficiency in iodine intake. Other than that, some factors like genetic susceptibility, female gender, age, and consumption of narcotics may cause this disease. In the case of hypothyroidism, the thyroid is unable to produce T3 and T4 and continues to grow to form a non-toxic goiter.

Additional Information:
 Let us know about both the conditions mentioned in the question:
Hypothyroidism is the condition where the thyroid gland of our body doesn't produce enough T3 or T4 hormones. It is not very noticeable at an early stage but over time it may cause symptoms like obesity, joint pain, infertility, etc. It causes non-toxic goiter which is the enlargement of the thyroid gland.
On the other hand, hyperthyroidism is the condition where the thyroid gland produces excessive thyroxine and results in unintentional weight gain and a rapid or irregular heartbeat. Antithyroid medications and radioactive iodine can cure this condition however sometimes even the requirement of surgery can be seen.
Therefore, the correct answer is “Hypothyroidism”.

Note: Non-toxic goiter is the enlargement of the thyroid due to its inability to produce T3 and T4. This condition appears without hyperthyroidism but in hypothyroidism. Before the toxic goiter appears which is associated with hyperthyroidism, often a non-toxic one already stays there for years.
