Overview

Treatment of gastroparesis depends on the severity of the symptoms. In most cases, treatment does not cure gastroparesis—it is usually a chronic condition. Treatment helps you manage the condition so you can be as healthy and comfortable as possible.

Medical Therapy

The medical therapy of gastroparesis is as follows:

Initial management

The first line management of gastroparesis consists of the following steps:[1][2][3][4]

  • Dietary modification
  • Hydration and nutrition
  • Optimize glycemic control
  • Pharmacotherapy

Dietary modification

Patients with gastroparesis should be advised the following dietary regimen.

Dietary modification in gastroparesis
  • Small, frequent meals five to six times a day
  • Low fat diet
  • Meals should be homogenized
  • Avoid carbonated drinks
  • High fibre diet
  • Cessation of alcohol and smoking

Hydration and nutrition

Optimize glycemic control

Pharmacotherapy

Prokinetics

Anti-emetics

Antibiotics

Gastric electrical stimulation

It is the preferred modality of treatment in the following patients:

  • Patients with symptoms refractory to medical therapy for at least one year.
  • It is beneficial for diabetics as it improves symptom serverity.

Medication

Several medications are used to treat gastroparesis. Your doctor may try different medications or combinations to find the most effective treatment. Discussing the risk of side effects of any medication with your doctor is important.

  • Metoclopramide (Reglan): This drug stimulates stomach muscle contractions to help emptying. Metoclopramide also helps reduce nausea and vomiting. Metoclopramide is taken 20 to 30 minutes before meals and at bedtime. Side effects of this drug include fatigue, sleepiness, depression, anxiety, and problems with physical movement.
  • Erythromycin: This antibiotic also improves stomach emptying. It works by increasing the contractions that move food through the stomach. Side effects include nausea, vomiting, and abdominal cramps.
  • Domperidone: This drug works like metoclopramide to improve stomach emptying and decrease nausea and vomiting. The FDA is reviewing domperidone, which has been used elsewhere in the world to treat gastroparesis. Use of the drug is restricted in the United States.
  • Other medications: Other medications may be used to treat symptoms and problems related to gastroparesis. For example, an antiemetic can help with nausea and vomiting. Antibiotics will clear up a bacterial infection. If you have a bezoar in the stomach, the doctor may use an endoscope to inject medication into it to dissolve it.
  • Viagra: Viagra which increases blood flow to the genital area, is also being used by some practitioners to stimulate the GI tract in diabetic gastroparesis.
  • Antidepressant: Mirtazapine has also proven effective in the treatment of gastroparesis unresponsive to conventional treatment. This is due to its anti-emetic and appetite stimulant properties. Mirtazapine acts on the same serotonin receptor as the popular anti-emetic Ondansetron[5].

Dietary Changes

Changing your eating habits can help control gastroparesis. Your doctor or dietitian may prescribe 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. In more severe cases, a liquid or pureed diet may be prescribed.

The doctor may 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

If a liquid or pureed diet does not work, you may need surgery to insert a feeding tube. The tube, called a jejunostomy, is inserted through the skin on your abdomen into the small intestine. The feeding tube bypasses the stomach and places nutrients and medication directly into the small intestine. These products are then digested and delivered to your bloodstream quickly. You will receive special liquid food to use with the tube. The jejunostomy is used only when gastroparesis is severe or the tube is necessary to stabilize blood glucose levels in people with diabetes.

Parenteral Nutrition

Parenteral 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 period with gastroparesis. Parenteral nutrition is used only when gastroparesis is severe and is not helped by other methods.

Gastric Electrical Stimulation

A gastric neurostimulator is a surgically implanted battery-operated device that releases mild electrical pulses to help control nausea and vomiting associated with gastroparesis. This option is available to people whose nausea and vomiting do not improve with medications. Further studies will help determine who will benefit most from this procedure, which is available in a few centers across the United States.

Botulinum Toxin

The use of botulinum toxin has been associated with improvement in symptoms of gastroparesis in some patients; however, further research on this form of therapy is needed.
