Professionals now think that even short-term hyperglycemia may cause problems of the GI tract. So now let's look at how gastroparesis can present itself. If you have this problem the grinding function of the stomach is greatly reduced or lost. Food can't be broken up into smaller pieces and doesn't move on to the intestines and bowel normally. Food stays in the stomach much longer than normal.
Dehydration is difficult for diabetics.
It can lead to diabetic ketoacidosis. Persistent vomiting can also make the lining of your stomach bleed. Because the food you eat remains in your stomach too long, vomiting may bring up food from a just eaten meal as well as food eaten up to 24 hours before. Some people with this condition vomit even when their stomach is empty as when they wake in the morning. The scary thing about gastroparesis is that a person with the condition may be perfectly fine for days or weeks at a time but then have hours or days of vomiting that will lead to hospitalization.
