The first probability I consider is the anesthesia for the appendectomy.
The trauma of anesthesia and surgery sets off a whole host of endocrine actions, reactions, and interactions.
It is probable that your body is still trying to find the set points of all the interacting systems that keep it in balance.
The six week point, where you are now, is still relatively early in the recovery. You may feel fine, but your metabolism may well still be in the balancing process.
Decades ago, when medical students were simply put under anesthesia, Dr. Francis Moore documented that it took several months for full metabolic recovery.
Let me know if you need further information.
