Probably were caused by lupus because I didn't have them before getting lupus and haven't had them for years. I believe it was general inflammation and caused problems absorbing nutrients and meds. No further GI issues.
I was very, very ill with lupus and polymyositis and almost died in 2005. Lost 40 lbs of muscle in a week which left me fighting for my life, quadriplegic and with a feeding tube. Lupus attacked my GI tract, kidneys, blood and all my joints. Also some cognitive impairment. PM has been in remission for 12 years but lupus came back attacking my liver and blood. Still dealing with extremely low platelets now. Guys who get lupus at an old age (mid 60s) tend to have different issues and much more severe than younger patients.
Lupus can attack any part of our body and every case is different. General treatment for lupus usually helps but not always. Many try diet changes but I am skeptical of much of that but some claim it helps. Worth a try particularly if your diet is not good anyway.
