My grandpa has gastroparesis, due to diabetes. I want to move in with him for a while and take care of him- watch his diet and help check his insulin level, and sort out medications with him (make sure he takes the right ones at the right time)- and just monitor his health overall. I need advice from gastroenterologists out there who can tell me what I need to do if I am to help my grandpa affectively make it better.

Gastroparesis is a condition in which the muscles in your stomach don't function normally.

Ordinarily, strong muscular contractions propel food through your digestive tract. But in gastroparesis, the muscles in the wall of your stomach work poorly or not at all, preventing your stomach from emptying properly. This can interfere with digestion, cause nausea and vomiting, and play havoc with blood sugar levels and nutrition.

No available treatment can cure gastroparesis. Dietary changes and certain medications sometimes help control symptoms of gastroparesis, but they're not effective in every case. And the available gastroparesis drugs can cause serious side effects. Researchers are investigating other types of therapies for gastroparesis.

Information on treatment can be found here that should be very helpful.
