When should you see a doctor for abdominal pain?
See a doctor, such as Dr. Khan, for abdominal pain that lasts more than a few days, keeps coming back, interferes with eating, sleep or work, or comes with changes in bowel habits, unexplained weight loss, ongoing nausea or heartburn that needs regular medicine. Go to the emergency room for sudden severe pain, a hard or swollen belly, fever with pain, vomiting blood, black or bloody stools, fainting, or pain during pregnancy.

When can abdominal pain wait for an appointment?
Abdominal pain can usually wait for a scheduled appointment when it is mild to moderate, you can eat and drink, you have no fever or bleeding, and it has been coming and going over days to weeks rather than suddenly getting worse. Examples include recurring bloating and cramps, pain linked to bowel movements, indigestion after meals and heartburn. Book a visit rather than waiting months.
| Situation | Where to go |
|---|---|
| Severe, sudden or worsening pain, or with fever or bleeding | Emergency room |
| Pain with vomiting or diarrhea lasting more than a day or two | Primary care or urgent care soon |
| Pain that keeps returning for weeks | Gastroenterologist |
| Pain with bowel changes, weight loss or anemia | Gastroenterologist promptly |
| Heartburn or indigestion needing medicine often | Gastroenterologist |
What should I tell the doctor about my pain?
Tell the doctor where the pain is, when it started, whether it is constant or comes and goes, what it feels like (burning, cramping, sharp, dull), what makes it better or worse, its relation to meals and bowel movements, and any other symptoms such as fever, vomiting, diarrhea, constipation, bleeding or weight loss. List your medicines, especially pain relievers.
- Location, and whether it moves
- Start date and how often it happens
- Type of pain and severity from 0 to 10
- Link to meals, bowel movements or periods
- Other symptoms and all medicines
Tip: Use a simple pain diary
For one to two weeks, note the time, location, severity and what you ate. A short diary often helps your doctor find the cause faster than any single test.
What does a gastroenterologist do for abdominal pain?
A gastroenterologist reviews your history and medicines, examines your abdomen, and orders tests based on the pattern, which may include blood and stool tests, H. pylori testing, an abdominal ultrasound or CT scan, and an upper endoscopy or colonoscopy. Common causes found include gastritis, ulcers, gallbladder disease, IBS, constipation, food intolerances and inflammatory bowel disease.

Frequently asked questions
How long is too long for stomach pain?
See a doctor if pain lasts more than a few days, keeps returning, or is severe at any point.
Should I go to urgent care or the ER for stomach pain?
Go to the ER for severe pain, a hard belly, fever, bleeding, fainting or pain in pregnancy. Urgent care can help with milder pain that is not improving.
Can I take pain medicine for abdominal pain?
Avoid ibuprofen, naproxen and aspirin until the cause is known, as they can irritate the stomach. Ask a doctor before taking any pain reliever for ongoing pain.
What kind of doctor treats stomach pain?
Primary care doctors handle many cases first. A gastroenterologist treats ongoing or complex stomach and bowel problems.
Do I need a referral to see a gastroenterologist in Katy or Cypress?
It depends on your insurance plan. Many PPO plans let you book a specialist directly, while some HMO plans require a referral from your primary care doctor. Call (346) 340-4414 and the team can help you check.
