Hi there! Unfortunately, AI diseases seem to be like potato chips or cookies. You may think you can have just one, but soon enough, you have a few more.
Welcome to the forum!
Sorry i can't help too much - I have fibromyalgia, and not Lupus- but with the diarrhea - the thing you should look out for is if it's green. If you keep having green feces, it means that your body isn't properly digesting the nutrients in your food because it's going through your body too quickly. Of course, green feces can also be caused by green food coloring as well, just so you know. But if you keep having this you might want to ask a doctor. In the mean time, you should just try to make sure you stay hydrated, and possibly eating foods easy on your stomach, such as yogurt (especially greek), or some light fruits and nuts.
Sorry I couldn't be of more help - just wanted to pop by and make sure you were welcomed to the forum! I'm glad you've found us It's a great place to talk to people who know what you're going through, especially nice when it comes to rants, hehe.
