About Gastroparesis

A. Gastroparesis is a chronic digestive condition where the stomach muscles do not function properly, leading to delayed or absent stomach emptying without a physical blockage. As defined by the Mayo Clinic, gastroparesis “affects the normal spontaneous movement of the muscles (motility) in your stomach.” This impaired motility can interfere with digestion, nutrient absorption, and overall quality of life. In short, gastroparesis is a form of stomach paralysis.

A. Symptoms can range in severity and may come and go. Common signs include:

• Nausea
• Vomiting (especially undigested food hours after eating)
• Feeling full quickly after beginning a meal
• Early satiety (feeling full after just a few bites)
• Bloating
• Abdominal pain or discomfort
• Acid reflux or heartburn
• Loss of appetite
• Weight loss and signs of malnutrition

A. Gastroparesis can be challenging to diagnose due to symptom overlap with other GI disorders. Diagnosis typically involves ruling out structural problems and then confirming delayed stomach emptying.

The most common tests include:

• Gastric Emptying Study (GES): The gold standard test, involving a small meal (often eggs with a tiny amount of radioactive material) tracked by a scanner to measure how quickly the stomach empties.
• Upper GI Endoscopy: Used to examine the stomach lining and rule out blockages or ulcers.
• Upper GI Series (Barium Swallow): X-ray imaging to observe the movement of food through the stomach and small intestine.
• SmartPill (Wireless Motility Capsule): A newer, capsule-based test that records pH, temperature, and pressure as it travels through the digestive tract.

A. The causes of gastroparesis can vary and may remain unknown in many patients.

The most common identified causes include:

• Idiopathic (unknown cause): This accounts for a large number of cases.
• Diabetes (Type 1 or Type 2): High blood sugar can damage the vagus nerve, which helps regulate stomach muscles.
• Post-surgical complications (e.g., vagus nerve injury)
• Viral infections
• Neurological conditions (e.g., Parkinson’s, multiple sclerosis)
• Autoimmune diseases
• Medications that slow digestion (such as opioids, anticholinergics, or some antidepressants)

A. Gastroparesis is considered a rare disease, though awareness and diagnoses have increased. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), it is estimated that up to 5 million people in the United States may be affected. However, because the condition is under-diagnosed and often misdiagnosed, the true number may be higher. The Mayo Clinic classifies it as a condition that affects fewer than 200,000 Americans annually in terms of formal diagnosis.

A. While there is no cure, a combination of treatments can help manage symptoms and improve quality of life.

Treatment options include:

• Dietary Changes: Eating smaller, more frequent meals; avoiding high-fat and high-fiber foods; and focusing on easily digestible, low-residue meals.
• Medications
• Prokinetics (e.g., Metoclopramide, Erythromycin) to stimulate stomach contractions
• Antiemetics (e.g., Ondansetron/Zofran, Promethazine) to reduce nausea and vomiting
• Feeding Tubes: For severe cases where oral intake is not possible, jejunostomy tubes (J-tubes) may be placed to provide nutrition.
• Gastric Electrical Stimulation (GES): A surgically implanted device similar to a pacemaker that delivers mild electrical pulses to help move food. Success varies between individuals.
• Parenteral Nutrition: In rare cases, intravenous nutrition (TPN) is used when the gut cannot be used for feeding.
• Supportive care such as pain management, hydration, psychological support, and treatment of coexisting conditions is also important.

A. Unfortunately, there is currently no cure for gastroparesis. Management focuses on symptom relief, nutritional support, and improving quality of life. Research is ongoing to better understand the condition and develop more effective treatments.
