Gastroparesis
Videos
Overview
Gastroparesis is a chronic disorder in which the stomach empties food into the small intestine more slowly than normal. This delayed gastric emptying occurs without a physical blockage and leads to symptoms such as nausea, vomiting, bloating, early satiety, and abdominal discomfort. Gastroparesis can significantly impact nutrition, hydration, and quality of life.
Causes
Common causes include diabetes, vagus nerve injury (often after surgery), viral infections, autoimmune disorders, medications that slow gastric motility, and idiopathic factors. Diabetes is the most frequent cause due to nerve damage affecting stomach function.
Risk Factors
Risk factors include long‑standing diabetes, prior abdominal or esophageal surgery, autoimmune disease, neurological disorders, viral infections, and medications such as opioids or anticholinergics.
How Gastroparesis Affects the Body
Delayed gastric emptying leads to food remaining in the stomach for prolonged periods, causing nausea, vomiting, bloating, malnutrition, dehydration, and unstable blood sugar levels. Severe cases may result in bezoars (hardened masses of undigested food).
Complications
Complications include malnutrition, dehydration, erratic glucose control, bezoar formation, weight loss, and repeated hospitalizations for nausea and vomiting.
Symptoms & Signs
Symptoms include nausea, vomiting, early fullness, bloating, abdominal discomfort, loss of appetite, weight loss, and fluctuating blood sugar levels. Some patients experience reflux or regurgitation.
Diagnosis
Diagnosis is made through gastric emptying studies (gold standard), endoscopy, imaging, and breath tests. Endoscopy rules out mechanical obstruction.
Differential Diagnosis
Conditions that mimic gastroparesis include gastric outlet obstruction, functional dyspepsia, GERD, peptic ulcer disease, biliary disease, and small bowel disorders.
Lifestyle Modifications
Lifestyle changes include eating small frequent meals, choosing low‑fat and low‑fiber foods, avoiding carbonated beverages, staying hydrated, and optimizing blood sugar control in diabetic patients.
Treatment Options
Treatment includes dietary modification, prokinetic medications, anti‑nausea medications, gastric electrical stimulation, endoscopic therapies, and in severe cases, surgical interventions. Managing underlying conditions such as diabetes is essential.
When to See a Doctor
Seek medical evaluation if you experience persistent nausea, vomiting, early fullness, unexplained weight loss, dehydration, or difficulty maintaining nutrition.
When to Seek Treatment
Treatment is recommended when symptoms interfere with eating, hydration, or blood sugar control, or when complications such as weight loss or malnutrition occur.
Long-Term Outlook
Long‑term management focuses on symptom control, nutritional support, and treatment of underlying conditions. Ongoing follow‑up is important to prevent complications.
Prognosis
Gastroparesis is chronic but manageable. Many patients improve with dietary changes, medications, and targeted therapies. Severe cases may require advanced interventions.
