Is iodine good for underactive thyroid?

My endocrinologist explained that while iodine is needed to make thyroid hormones, an underactive thyroid (hypothyroidism) in urban areas is rarely caused by iodine deficiency anymore due to iodized salt. In fact, excessive iodine can cause a sudden flare-up. He strictly advised me to only take the prescribed thyroxine sodium tablets.

Haan na, thyroid issues are so tricky and exhausting to manage. People think iodine means just eating more salt, but it doesn't work like that. It is better to avoid taking any step without asking your doctor, ho na.

If you are vegetarian, you can get normal iodine levels from milk, curd, and iodized salt. You don't need external pills which can disturb your hormone balance. Focus on a balanced diet with proper selenium and zinc, but always let your doctor guide your thyroid therapy.

I have an underactive thyroid too, and I used to think taking extra iodine would cure it. But my doc explained that in India, most cases are actually Hashimoto's, where extra iodine doesn't help and can even harm. Just stick to your daily thyroid medication and get regular checkups.
