Hi Rebecca, adrenal exhaustion often follows hypothyroid disease. If you read the information that comes with the thyroid medication, it warns against taking it when you have adrenal problems. My experience has been that the adrenal issues are completely ignored, and in fact no doctor has ever requested adrenal testing for me.
However, I know that as thyroid disease advances and continues iunfreated, you will have adrenal problems. The adrenals, thyroid and pancrease work together to regulate energy and metabolism in your body, along with the rest of your endocrine system. So when one part is down, the others are affected.
There are a bunch of problems that tend to accompany thyroid disease: adrenal exhaustion, gut and digestion problems (ibs), heart disease, anxiety, migraines, pre diabetes, and autoimmune disease. For this reason, a holistic approach is most effective.
The other issue you could be dealing with is that levothyroxin is T4 only, so you could have low T3. Your body produces both T4 and T3. And in fact the idea with the levo is to provide the body with T4 and let the body convert to T3. This works ok at low doses, or if your gut is healthy. The T3 is a much more active form of thyroxin and seems to be closely related to adrenal responses, as fluctuations in T3 can result in anxiety. Also, if your T4/T3 ratio is out of whack, it can result in anxiety, which further stresses the adrenals.
My guess is your doc is just trying to figure out what's going on.
The good news is that your doc actually checked your adrenals. Most don't. 0
