Having GP and diabetes you have to be on a strict diet. It will suck at times because their will be days and sometimes weeks where you cant eat ANYTHING due to the nausea. When this happens it gets hard to ignore the hunger, unfortunately this becomes normal and you get used to it. Even if you chew on an ice cube it will come up. Vomiting causes the pain to get worse so you basically will do anything to aviod vomiting.
At first when living with GP and diabetes you have to figure out what foods work best for you. I've found out that food becomes "trial and error" until you figure out what makes you sick, real sick, and feeling good! The stomach is sensitive to everything so for awhile meals and snacks will consist of clear fluids and full fluid diets.Then I slowly add in soft easy to digest foods like soups, yogurts, puddings, crackers. There's two things I can usually keep down, even if I'm in the hospital, and they are pretzels and candies, usually mike'n Ikes! so good! lol I slowly add in eggs, white bread, white rice, and white pasta, I have to stay away from whole wheat because its harder to digest. Then I add cooked vegetables and blended fruits, I can usually eat all melons whole at this time. Next I add chicken, turkey and all fish, cooked any way. No red meat just poultry in my diet. Red meat takes too long to digest and causes a flare up. Going from a clear fluid diet to a solid food diet takes a couple weeks to accomplish and it is hard but I'll do anything to feel better and if that means I have to live on a strict diet then so be it:) When I'm at my healthiest, I can eat raw fruits and vegetables, which is a big deal to me because I love fruits and veggies. The only limitations I have at my best are no red meat, no whole wheat, very little fat, and very little fiber. So it's not too bad...when health is good:)
From the Mayo Clinic
STEP 1 DIET consists of liquids, which usually leave the stomach quickly by gravity alone. Liquids prevent dehydration and keep the body supplied with vital salts and minerals.
STEP 2 DIET provides additional calories by adding a small amount of dietary fat -- less than 40 gm each day. For patients with gastroparesis, fatty foods and oils should be restricted, because they delay stomach emptying. However, patients at the Step 2 level are usually able to tolerate this amount.
STEP 3 DIET is designed for long-term maintenance. Fat is limited to 50 gm per day, and fibrous foods are restricted, because many plant fibers cannot be digested.
The STEP 1 Gastroparesis Diet is inadequate in all nutrients except sodium and potassium. It should not be continued for more than three days without additional nutritional support. STEP 2 and STEP 3 Gastroparesis Diets may be inadequate in Vitamins A and C, and the mineral iron. A multi-vitamin supplement is usually prescribed.
