Endocrinology-Diabetes Questions Diabetes

If I have diabetes, do I have higher chances of having an overactive thyroid?

I have been diagnosed with diabetes recently. I am worried that It could cause other problems in my body too. Can diabetes also lead to an overactive thyroid?

It depends on the type of diabetes. Type 1 diabetics who have an autoimmune condition (antibodies attack the islet cells that damages them and thus there is a serious decrease in insulin, or even no insulin production), do have increased thyroid problems. Thyroid problems however is very common in the population at large.

Dear patient,

If you have type 1 (insulin dependent diabetes which is due to auto immunity) you do have a higher chance of developing auto immune hyperthyroidism as well as other autoimmune disorders. In type 2 diabetes, there is no connection with hyperthyroidism except that it can worsen diabetes if the hyperthyroid condition develops. Hypothyroidism due to its effect on metabolism, e.g., weight gain, effect on insulin secretion can lead to diabetes.

Yes, and you also have the possibility of presenting with low thyroid- hypothyroidism. Have your doctor check your thyroid function tests once yearly.
Rarely. Thyroid disease can be a part of a syndrome of endocrine organs that are attacked by the immune system. This can include loss of adrenal gland, celiac disease, loss of hair, loss of skin pigment, etc. This problem is due to autoimmunity and results in a loss of function of the glands due to destruction. So, the result is usually loss of function, not an increase. Hypothyroidism is the usual problem with diabetes, not hyper or overactive, though this can occur. In any case, get the overactive thyroid problem taken care of, because it may make the diabetes hard to control as well as its effect on other organs, such as the heart.
