What causes stomach and abdominal pain?
Abdominal pain is pain anywhere between your chest and your groin. Most of the time it comes from a common, short-term problem, such as a stomach bug, gas, constipation, indigestion or acid reflux. Less often it is a sign of something that needs fast treatment, such as appendicitis or a gallbladder problem.
Where the pain is, how it started and what comes with it, such as fever, vomiting or changes in your bowel movements, help your provider find the cause. At Texas Primary Care Associates, most stomach problems are diagnosed and treated in the office, with imaging or a specialist arranged when needed.
- Exam of your abdomen and vital signs
- Urine or blood tests when they will guide treatment
- Medicine, diet and fluid advice to help you recover
- Referral for imaging or a specialist if needed

What can pain in different parts of the belly mean?
The location of your pain is one clue to its cause. It is not a diagnosis, so get checked if pain is strong, lasting or comes with other symptoms.
| Common causes | Usually fine for a clinic visit | Get emergency care if | |
|---|---|---|---|
| Upper middle | Indigestion, heartburn, acid reflux, gastritis or an ulcer | Burning or aching pain that comes and goes | Pain spreads to your chest, jaw or arm, or you vomit blood |
| Upper right | Gallbladder or liver problems | Mild pain after fatty meals | Severe pain with fever, or yellow skin or eyes |
| Lower right | Appendicitis, constipation or gas | Mild pain that is easing | Pain that gets worse, especially with fever or vomiting |
| Lower left | Constipation, gas or diverticulitis | Mild to moderate pain | Severe pain with fever or a hard, swollen belly |
| All over or crampy | Stomach bug, food poisoning or gas | Cramping with diarrhea when you can keep fluids down | You cannot keep fluids down or have signs of dehydration |
When stomach pain needs a doctor
Mild stomach pain from gas or a passing stomach bug often improves with rest, fluids and bland food. Pain that is severe, lasts more than a day or two, keeps coming back or comes with fever, vomiting or blood needs a medical exam. At Texas Primary Care Associates, stomach pain visits are handled by the same team that provides ongoing primary care.
Signs you should come in
- Pain that lasts more than a day or keeps coming back
- Vomiting that keeps you from holding down fluids
- Diarrhea that lasts more than two days
- Fever with stomach pain
- Heartburn more than twice a week, or heartburn that medicine does not help
- Weight loss you cannot explain
Staying hydrated with a stomach bug
Vomiting and diarrhea cause your body to lose water and salts. Take small, frequent sips of water or an oral rehydration drink, then add bland foods as you feel better. Signs of dehydration include very dark urine or little urine, dizziness when standing and a very dry mouth. Young children and older adults become dehydrated faster.
What to tell your provider
- Where the pain is and whether it moves
- When it started and whether it comes and goes
- What you have eaten and any recent travel or sick contacts
- Your bowel movements, including any blood or black stool
- Medicines you take, including pain relievers like ibuprofen
