Hi Customer (name blocked for privacy),
I can understand the mental and the physical trauma that you have undergone over the past few months. I will try to answer your queries as best as possible.
First of all, pancreatitis can occur after a major surgery, specially if there is sepsis or infection postoperatively. In your case, since you had a severe scar infection, pancreatitis might be related to the surgery and subsequent infection. On the other hand pancreatitis being an episode not related to any precipitating cause can also be not ruled out.
In acute pancreatitis one of the signs seen is acute fall in blood pressure. After two weeks if the fall in BP is persisting, it can be due to pancreatitis. On the other hand reviewing your other symptoms of weight loss, fatique, low BP, I think you might be haiving Addison's disease. This results from decreased production of cortisol hormone. This hormone is secreted from adrenal glands situated above the kidney. In your case the reason for this could be the high level of stress your body has undergone (due to major surgery, infection, repeated hospitalisation). To diagnose it you need to undergo blood tests to determine the level of cortisol and maybe also a CT scan of the abdomen. The treatment is to regulate the normal levels of the hormone in the blood by supplementing it.

I would advise you to discuss the possibility of Addison's disease with your doctor.
