@khauert - Thanks for your detailed answer! First of all- you will eventually find out what’s happening to you when you see the Mayo doctors. Your story sounds similar to my daughter’s story. She was healthy enough through high school - competitive swimmer too. In college she first got very sick with mono -2 nd time. She started to put on a lot of weight- she was eating a lot and no exercise. In her teens she was diagnosed with fibromyalgia. It got much worse in college. Had to stop swimming, received lidocaine infusions. At the end of high school she was diagnosed with depression. After college she moved to FL for work. Dx bipolar disorder. Big weight gain, hypothyroid, diabetes, infections. Finally, her psychiatrist (!) diagnosed her with Cushing’s disease. The same week she had seen her endocrinologist for diabetes who yelled at her for being fat, she saw her internist and cardiologist- she had tachycardia and cardiologist just put her on medication without wondering why.
Anyway, we helped find a superb endocrinologist- diagnosed pituitary adenoma- Cushing’s disease- with excessive cortisol production. She was then referred to a dedicated pituitary center at a major university hospital. Tumor removed.
This shows how our bodies can fool us and why many people don’t get diagnosed for years. It is great that you will go to Mayo!!
