In the morning, the thyroid examination is recommended to do fasting. What does fasting mean and how to do this fast, is it okay to eat 1 tablespoon or drink water ???
Thank you for asking the HealthReplies.com Community
The thyroid is a gland located at the front of the neck and is shaped like a butterfly. This gland belongs to the important endocrine system in the body. Because the thyroid will produce important hormones, namely T3 and T4, which function to regulate our body's metabolism.
Thyroid hormone examination aims to see the balance of hormones produced, whether normal, hypothyroid, or hyperthyroid. This examination usually checks for 3 main hormones namely Thyroid Stimulating Hormone (TSH), FT (Free Thyroid) 3 and 4. This examination is not actually required by fasting because it is not influenced by food. It is different if besides checking your thyroid hormone it is also recommended to check your glucose, cholesterol, triglycerides or uric acid levels, etc. If you are checking other than thyroid function, you are required to fast for at least 10 hours before taking blood, except for a minimum of 8 hours of fasting glucose. To check triglycerides, the patient should fast for 12 hours. During fasting, the patient is not allowed to eat and drink, except plain water.
This is the information we can convey, thank you, hope it helps.
