Gastrointestinal complaints (abdominal pain, GI issues)
Your doctor will ask detailed questions about your symptoms — where the pain is located, when it started, what makes it better or worse, and whether you also have nausea, vomiting, changes in bowel habits, fever or weight loss. They’ll ask about your diet, travel, medications, and past surgeries. A gentle exam of your abdomen helps identify tenderness, swelling or masses. Depending on the suspected cause, the doctor may order blood tests (to check red and white blood cell counts, electrolytes, liver and kidney function, pancreatic enzymes and inflammation markers), a urine test, pregnancy test or stool tests for blood or infection to narrow down the diagnosis. If pain is severe or persistent, imaging such as ultrasound or CT scan may be used, and endoscopy or colonoscopy may be recommended for chronic digestive symptoms.
Treatment depends on the cause. Over‑the‑counter acid reducers (antacids, histamine‑2 blockers or proton pump inhibitors) relieve heartburn and ulcers. Anti‑diarrheal medicines like loperamide and bismuth subsalicylate control loose stools, while fiber supplements, stool softeners or osmotic laxatives help constipation. Anti‑spasmodic medicines (e.g., dicyclomine) and probiotics may ease irritable bowel symptoms. Anti‑nausea drugs such as ondansetron or meclizine reduce vomiting. For infections, your doctor may prescribe antibiotics or antiparasitic medications when appropriate. Pain relievers such as acetaminophen can be used, but avoid high‑dose NSAIDs, which may irritate the stomach.
A complete blood count looks for anemia or elevated white blood cells suggesting infection or inflammation. A metabolic panel checks electrolytes, liver enzymes, kidney function and blood sugar. Inflammatory markers like C‑reactive protein or erythrocyte sedimentation rate help determine if there is acute inflammation. Pancreatic enzymes (amylase and lipase) may be measured for suspected pancreatitis. Pregnancy testing is done in people of child‑bearing age. Stool tests can detect blood, pathogens (bacteria, viruses or parasites), fat malabsorption or signs of colon cancerhttps://my.clevelandclinic.org/health/diagnostics/25210-stool-test#:~:text=A%20stool%20test%20looks%20for,issues%2C%20including%20infections%20and%20cancers. Breath tests may be used to diagnose Helicobacter pylori infection, lactose intolerance or small‑intestinal bacterial overgrowth.
Imaging is chosen based on the suspected condition. Abdominal ultrasound is used to evaluate the gallbladder, liver, pancreas and kidneys. Computed tomography (CT) scans provide detailed images of the entire abdomen and are commonly ordered for severe or unclear abdominal pain, appendicitis or diverticulitis. Upper GI series, barium swallow or small bowel follow‑through can show structural problems, ulcers or tumors. Endoscopy (EGD) allows the doctor to look at your esophagus, stomach and first part of the small intestine; colonoscopy examines the large intestine. For chronic constipation or motility disorders, tests such as a colorectal transit study or defecography may be ordered.
Seek urgent care for severe, sudden or worsening abdominal pain; pain with fever, persistent vomiting or inability to keep fluids down; bloody or black tarry stools; vomiting blood or coffee‑ground material; abdominal swelling or severe tenderness; jaundice; or unintentional weight loss. Call your doctor if you have ongoing heartburn, difficulty swallowing, persistent changes in bowel habits, unexplained diarrhea, constipation, bloating, gas or nausea that does not improve after a few dayshttps://share.upmc.com/2020/09/when-should-you-see-a-gi-doctor/#:~:text=A%20problem%20anywhere%20in%20your,body%20needs%20to%20stay%20healthyhttps://www.mayoclinic.org/symptoms/abdominal-pain/basics/when-to-see-doctor/sym-20050728#:~:text=Seek%20help%20if%20your%20abdominal,severe%20and%20is%20associated%20with.
Follow‑up depends on the diagnosis. For uncomplicated heartburn or stomach upset, see your doctor if symptoms persist beyond two weeks. People with irritable bowel syndrome or inflammatory bowel disease may need visits every 3–6 months. After starting new medications or after an acute episode of diverticulitis or pancreatitis, your provider may recheck you within a few weeks. Screening colonoscopy is typically repeated every 5–10 years, or sooner if polyps are found or you have inflammatory bowel disease.
Maintain a balanced diet rich in fiber (fruits, vegetables, whole grains and legumes) and avoid trigger foods such as fatty, fried or very spicy dishes and large amounts of caffeine, chocolate, citrus, tomatoes and alcoholhttps://www.hopkinsmedicine.org/health/wellness-and-prevention/gerd-diet-foods-that-help-with-acid-reflux-heartburn#:~:text=Foods%20That%20May%20Cause%20Heartburn. Eat smaller meals and avoid lying down for at least two hours after eating. Stay hydrated by drinking plenty of water. Don’t smoke and limit alcohol intake. Exercise regularly and maintain a healthy weight. Wash hands and prepare food safely to prevent infections. Manage stress with relaxation techniques, as stress can worsen digestive symptoms.
Primary care doctors manage most GI complaints, but may refer you to a gastroenterologist for persistent symptoms, abnormal tests or specialized procedures such as endoscopy or colonoscopy. Nutritionists can help you develop a diet that avoids triggers and supports gut health. If tests reveal gallstones, ulcers or inflammatory bowel disease, surgeons or hepatobiliary specialists may be involved. Mental health providers may assist with stress‑related GI disorders. Communication among your care team ensures that lab results, imaging and treatment plans are coordinated.
