Meal and Food Changes for Treating GastroparesisChanging your eating habits can help control gastroparesis. Your doctor or dietitian will give you specific instructions, but you may be asked to eat six small meals a day instead of three large ones. If less food enters the stomach each time you eat, it may not become overly full. Or the doctor or dietitian may suggest that you try several liquid meals a day until your blood glucose levels are stable and the gastroparesis is corrected. Liquid meals provide all the nutrients found in solid foods, but can pass through the stomach more easily and quickly.
The doctor may also recommend that you avoid high-fat and high-fiber foods. Fat naturally slows digestion--a problem you do not need if you have gastroparesis--and fiber is difficult to digest. Some high-fiber foods like oranges and broccoli contain material that cannot be digested. Avoid these foods because the indigestible part will remain in the stomach too long and possibly form bezoars.
Feeding Tube for Gastroparesis SufferersIf other approaches do not work, you may need surgery to insert a feeding tube. The tube, called a jejunostomy tube, is inserted through the skin on your abdomen into the small intestine. The feeding tube allows you to put nutrients directly into the small intestine, bypassing the stomach altogether. You will receive special liquid food to use with the tube. A jejunostomy is particularly useful when gastroparesis prevents the nutrients and medication necessary to regulate blood glucose levels from reaching the bloodstream. By avoiding the source of the problem--the stomach--and putting nutrients and medication directly into the small intestine, you ensure that these products are digested and delivered to your bloodstream quickly. A jejunostomy tube can be temporary and is used only if necessary when gastroparesis is severe.
Parenteral Nutrition for GastroparesisParenteral nutrition refers to delivering nutrients directly into the bloodstream, bypassing the digestive system. The doctor places a thin tube called a catheter in a chest vein, leaving an opening to it outside the skin. For feeding, you attach a bag containing liquid nutrients or medication to the catheter. The fluid enters your bloodstream through the vein. Your doctor will tell you what type of liquid nutrition to use.
This approach is an alternative to the jejunostomy tube and is usually a temporary method to get you through a difficult spell of gastroparesis. Parenteral nutrition is used only when gastroparesis is severe and is not helped by other methods.
New Treatments for GastroparesisA gastric neurostimulator ("pacemaker") has been developed to assist people with gastroparesis. The pacemaker is a battery-operated, electronic device that is surgically implanted. It emits mild electrical pulses that stimulate stomach contractions so food is digested and moved from the stomach into the intestines. The electrical stimulation also helps control nausea and vomiting associated with gastroparesis.
The use of botulinum toxin has been shown to improve stomach emptying and the symptoms of gastroparesis by decreasing the prolonged contractions of the muscle between the stomach and the small intestine (pyloric sphincter). The toxin is injected into the pyloric sphincter.
