Introduction
Under normal circumstances, it is not recommended to eat durian before undergoing thyroid function tests. The secretion of thyroid hormones is closely related to the body's energy metabolism. Consuming durian may cause fluctuations in thyroid hormone levels, leading to test results that do not accurately reflect the baseline function of the thyroid. If the thyroid function test requires fasting, durian should also be avoided prior to the examination.

Generally, it is not recommended to eat durian before a thyroid function test. The detailed explanation is as follows:

Durian is a tropical fruit rich in nutrients such as sugars, proteins, and fats. After consumption, the body's metabolic state may change, potentially affecting the synthesis, secretion, and metabolism of thyroid hormones. Thyroid hormone secretion is closely related to energy metabolism; eating durian may cause fluctuations in thyroid hormone levels in the body, leading to test results that do not accurately reflect the baseline function of the thyroid gland.

If the thyroid function test requires fasting, durian should be avoided for 8–12 hours before the test. Additionally, durian contains a certain amount of iodine. If a patient has a thyroid disorder, such as hyperthyroidism or hypothyroidism, doctors may recommend limiting iodine intake for a period before the test to avoid affecting the test results.

It is advisable to maintain healthy lifestyle habits and avoid excessive intake of iodine-rich foods before a thyroid function test, which can help improve the accuracy of the test.
