Abdominal Pain and Bloating: When to See a GI Doctor

Abdominal pain and bloating are among the most common reasons people see a gastroenterologist. Most causes are not dangerous, but some need prompt treatment. Where the pain is and what makes it better or worse help point to the cause.

Common causes by location

• Upper middle: reflux, gastritis, ulcers, pancreatitis
• Upper right: gallstones and liver conditions
• Lower left: constipation, diverticulitis
• Lower right: appendicitis, Crohn's disease
• All over or changing: IBS, gas, infections

Bloating

Bloating often comes from constipation, IBS, gas-producing foods, artificial sweeteners, lactose intolerance, SIBO, or a slow-emptying stomach (gastroparesis). Keeping a food and symptom diary helps find patterns.

Red flags

• Sudden, severe pain, or pain with fever: seek emergency care
• Unplanned weight loss
• Black or bloody stools, or anemia
• Vomiting or trouble swallowing
• New symptoms after age 50
• A family history of colon or stomach cancer

Evaluation and treatment

We take a careful history and examine you, then choose tests that fit your symptoms, such as blood and stool tests, an ultrasound or CT, an upper endoscopy, or a colonoscopy. Treatment depends on the cause. Many people improve with diet changes, treating constipation, or medicines that calm the gut.
