Abdomen Pain: Causes, Symptoms, and Treatment

What kind of doctor treats Abdomen Pain?
Your primary care doctor or family doctor often checks belly pain first. You may also see a gastroenterologist (a doctor who treats the digestive system). You may also see a surgeon (a doctor who does operations). A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is abdomen pain?
Abdomen pain is pain you feel anywhere between your chest and groin. Belly pain that is not from an injury and lasts fewer than seven days is called acute belly pain. Almost everyone has belly pain at some point. Most of the time it is not serious.
How bad your pain is does not always show how serious the cause is. Gas cramps can cause very bad pain. Colon cancer or early appendicitis may cause only mild pain or no pain. Appendicitis is swelling of a small pouch near the start of the large bowel.
Symptoms
The way your pain feels gives clues about the cause:
- Generalized pain: you feel it in more than half of your belly, often from a stomach virus, indigestion, or gas.
- Localized pain: it stays in one spot and may mean a problem in an organ.
- Cramp-like pain: gas and bloating often cause it, and diarrhea often follows.
- Colicky pain: it comes in waves and is often severe. Kidney stones and gallstones often cause this kind.
Nausea (feeling sick to your stomach) and vomiting (throwing up) often come with belly pain.
Causes and who gets it
Some less serious causes of belly pain are constipation, irritable bowel syndrome (IBS, a long-term gut problem), food intolerance (such as trouble digesting milk sugar), food poisoning, and stomach flu.
Other causes include:
- Appendicitis.
- Gallbladder inflammation with or without gallstones (hard pieces that form in the gallbladder).
- Diverticulitis (inflammation and infection of the colon).
- Kidney stones and urinary tract infections (UTIs).
- Ulcers, and heartburn or gastroesophageal reflux (GERD), when stomach acid backs up into the food pipe.
- Inflammatory bowel disease (such as Crohn disease or ulcerative colitis), bowel blockage, and pancreatitis (swelling or infection of the pancreas).
- A hernia in which the intestine is stuck or twisted.
Left lower belly pain with fever and nausea (but no vomiting) can point to diverticulitis.
How doctors diagnose it
Your doctor starts with a physical exam and questions about your symptoms, history, and where and when the pain happens. Pain when the doctor presses and lets go, or belly muscles that tighten on their own, can suggest peritonitis (irritation of the lining inside your belly).
Tests may include blood, urine, and stool tests and a pregnancy test. Scans depend on where the pain is. Ultrasound is a test that uses sound waves to make pictures. It is the first choice for right upper belly pain. A CT scan is a special x-ray with detailed pictures. It is often used for pain that is spread out or low in the belly. In pregnancy, if ultrasound is not clear, doctors prefer MRI (a magnet scan) over CT when it is available.
Treatment
You can try home care steps to ease mild belly pain. Sip water or other clear fluids, and avoid solid food for the first few hours. If you have been vomiting, you can eat small amounts of mild foods, such as rice, applesauce, or crackers.
Do not take any medicine without talking to your provider first. Doctors can give pain relief when needed, and pain medicine does not make the exam less accurate. People with peritonitis often need urgent treatment or surgery.
When to see a doctor
Call 911 or go to the emergency room if you have sudden, sharp belly pain, or if your belly is rigid and hard to the touch. Also call if you have trouble breathing, faint, or feel confused or very hard to wake up, if you cannot pass stool and are vomiting, or if you are vomiting blood or have blood in your stool (especially bright red, maroon, or black and tarry). Also call if you have chest, neck, or shoulder pain with the belly pain, if you had a recent injury to your belly, or if you are pregnant or could be pregnant and have belly pain.
Call your provider if the discomfort lasts a week or longer, or if the pain does not improve in 24 to 48 hours. Also call for a fever with the pain, or if you cannot keep down food or liquid.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. This kind of doctor can do the first exam, order tests, watch mild symptoms over time, and refer you to a specialist if needed.
Common questions
How do I know if my belly pain is serious?
How bad it hurts does not tell you. Mild pain can still be serious, and gas cramps can hurt a lot. Call 911 or go to the emergency room for sudden sharp pain, a hard and rigid belly, trouble breathing, fainting, vomiting blood, or blood in your stool.
What causes cramp-like belly pain?
Gas and bloating often cause it. Diarrhea often follows. Watch for pain that lasts more than 24 hours or comes with a fever.
What tests might I get for belly pain?
You may give blood, urine, or stool samples and have a pregnancy test. Common scans are ultrasound and CT. Ultrasound is the first choice for right upper belly pain.
