Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Gastrointestinal bleeding
Bleeding in the digestive tract, often from peptic ulcers, which may appear as blood in vomit or black, tarry stools.
Seek immediate emergency care if you experience vomiting blood, bloody stools, or signs of blood loss such as dizziness or fainting.
Severe persistent pain
Intense, unrelenting abdominal pain that may indicate complications such as ulcer perforation or pancreatic involvement.
Seek immediate emergency care for sudden, severe abdominal pain that does not improve.
Recurrent abdominal pain
(gastrointestinal)Persistent pain in the upper abdomen, often occurring after meals, due to excess stomach acid production irritating the stomach lining.
Frequency: 70-80% of patients
Heartburn and acid reflux
(gastrointestinal)Burning sensation in the chest and throat caused by stomach acid flowing back into the esophagus due to increased gastric acid secretion.
Frequency: 75-85% of patients
Chronic diarrhea
(gastrointestinal)Loose, watery stools occurring frequently throughout the day, resulting from excess gastric acid stimulating intestinal motility.
Frequency: 60-70% of patients
Nausea with vomiting
(gastrointestinal)Feeling of sickness with an urge to vomit, often triggered by stomach acid irritation and delayed gastric emptying.
Frequency: 50-60% of patients
Peptic ulcers
(gastrointestinal)Open sores in the stomach or duodenal lining caused by excessive acid production eroding the protective mucosal layer.
Frequency: 40-50% of patients
Unintentional weight loss
(constitutional)Gradual loss of body weight without trying, often due to reduced appetite, malabsorption, and chronic diarrhea associated with high gastrin levels.
Frequency: 35-45% of patients
Bloating and early satiety
(gastrointestinal)Feeling of fullness and abdominal distension even after eating small amounts, caused by delayed stomach emptying from acid overproduction.
Frequency: 40-50% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
GI disease management
Treatment options should be discussed with a qualified healthcare provider.
Proton pump inhibitor therapy
Acid-suppression medication to reduce gastric acid production when elevated gastrin is contributing to esophageal or gastric irritation. Long-term use requires evaluation of underlying cause.
H. pylori testing and eradication
Testing for Helicobacter pylori infection, which can cause hypergastrinemia, followed by appropriate antibiotic eradication therapy if positive.
Additional treatment options
Gastric-friendly dietary modifications
Avoidance of known gastric irritants including spicy foods, caffeine, alcohol, and acidic beverages. Emphasis on smaller, more frequent meals and adequate hydration.
dietaryEndoscopy and gastrin monitoring
Upper endoscopy to evaluate gastric mucosa and serial gastrin level measurements to assess treatment response and identify persistent abnormalities.
monitoringH2 receptor antagonist therapy
Alternative acid-suppression therapy using H2 blockers for patients who do not tolerate proton pump inhibitors or need step-down therapy.
