2019 Blood test results - more kidney function degradation :(

I have been suffering on and off from intestinal inflammation over the last four months, causing abdominal pain and discomfort. The initial attacks seem to have been triggered from eating a peanut and dried fruit trail mix (on four occasions after eating said trail mix I had symptoms within a few hours / next morning) but it's not clear whats causing the symptoms to remain three months later. An ultrasound shows no other problems except the inflammed small intestine. A specialist ordered lab tests (which I was overdue for anyway), antiparasite medication (which had no effect), and an anti-inflamation medicine, which also has had little effect. Unfortunately the lab tests show a ~10% degradation of kidney function compared to tests a year ago: I feel this degradation of kidney function may be related to the the intestinal inflammation (maybe whatever is causing this is also causing kidney inflammation) and so hope to get this resolved as soon as possible and start a renewed effort to improve my overall health with daily exercise and more careful attention to diet! Will test again after a few months of dedicated wellness activies and see if it shows any improvement.
