Endocronologist (Pediatric) Questions Low carb diet

Can a low carb diet help in controlling an overactive thyroid?

My daughter has an overactive thyroid that is leading to weight gain and irregular periods. Will a low-carb diet help in controlling an overactive thyroid?

The question is a bit confusing since overactive thyroid problems, called hyperthyroidism or Grave's Disease, are associated with unexplained weight loss as the entire hormone system is in overdrive. Both hypothyroidism and hyperthyroidism can be associated with irregular periods, however. Low-carb eating isn't directly related to either over- or under-active thyroid problems. But, with any weight excess, cutting back carbs allows the body to use less insulin and that combination can be associated with easier and significant weight loss for many people.

I'd also advise going back to your physician and medical team to review whether you are talking about hypothyroidism or hyperthyroidism.

There is no published research that a low-carb diet will control an overactive thyroid. However, there are medications to treat an overactive thyroid.

Overactive thyroid ( hyperthyroidism) leads to weight loss and frequent menses. In the other hand, underactive thyroid ( hypothyroidism) leads to weight gain and skipping periods. Low carb diet is very healthy but it will not affect her thyroid status.
