How to eat, drink and take medicine after total thyroidectomy?

After total thyroidectomy, the body no longer has an organ that produces hormones that regulate metabolism. To maintain normal life activities, you need to use hormone replacement every day. Nutrition at this time plays a role in supporting the body’s recovery, while ensuring optimal drug absorption to maintain stable hormonal concentrations. Some things to note are as follows:

Take medicine 3-4 hours before meals

Synthetic thyroid hormones are often sensitive to the gastric environment. For the drug to be best absorbed into the blood, you should take the drug in the morning as soon as you wake up, on an empty stomach, at least 30-60 minutes before breakfast. If you are busy with work and can’t drink it in the morning, you can drink it before going to bed, but make sure there is at least 3-4 hours between your last meal so your stomach can fully digest the food.

Pay attention to the distance between taking medicine

Some food groups have the ability to reduce the bioavailability of hormone replacement drugs, typically soybeans and soy products. Compounds in soybeans can prevent hormone absorption through the intestinal lining. You do not need to completely stop eating this food, but you should eat it at least 4 hours before taking the medicine.

Calcium and iron are the two minerals that cause the strongest interactions with drugs. Milk, yogurt or foods fortified with these nutrients may reduce drug levels in the blood. Therefore, you should not take thyroid hormone with milk or take it at the same time as bone and joint supplements or blood supplements. Instead, you should keep a safe distance of 2-4 hours.

Prioritize foods rich in zinc, magnesium and B vitamins

Foods rich in zinc and magnesium found in nuts (almonds, cashews, whole grains)… support energy metabolism. B vitamins reduce the feeling of fatigue, help the body recover quickly, and support the endocrine system. Patients after thyroidectomy should cook cruciferous vegetables (cabbage, cauliflower) to reduce goitrogens – substances that inhibit the thyroid.

If after surgery, you are prescribed adjuvant treatment with radioactive iodine (I131), your doctor will require a strict iodine diet (avoid iodized salt, seafood, egg yolks) for about 2 weeks before taking the radioactive drug. However, after completing this treatment, you can return to your normal iodized salt diet to support other organs in the body.

You need to be cautious when using functional foods or herbs of unknown origin. Some ingredients can distort TSH (thyroid-stimulating hormone) test results, causing doctors to adjust the medication dose incorrectly, causing prolonged hormone excess or deficiency.
