Abdominal pain that lasts for weeks or keeps returning is a different problem from a 24-hour stomach bug. It can be dull, sharp, crampy, or burning. It may sit just under your ribs, wrap around one side, or settle low in the pelvis. Doctors don’t treat belly pain as a single condition because the abdomen holds organs from several systems: the gut, liver, gallbladder, kidneys, and reproductive organs. The top 7 causes of persistent abdominal pain below account for many of the patterns seen in clinics, along with clues that help separate a temporary upset from something that needs a proper workup.
1. Irritable Bowel Syndrome (IBS)
Irritable bowel syndrome, or IBS, is one of the most common reasons for recurring belly pain. The classic pattern is cramping that eases after a bowel movement, often with bloating, gas, diarrhea, constipation, or both. Symptoms may follow meals or stress. They can flare for a few days, settle, then return. Standard tests usually show no visible inflammation or damage, which is why IBS is called a functional disorder. It still deserves attention because pain and urgency can disrupt work, travel, and sleep. A useful first step is tracking foods, stress, and bowel habits for two to four weeks. A doctor can check whether your symptoms fit IBS or overlap with another problem, such as common digestive disorders with symptoms you shouldn’t ignore.
2. Gastritis and Peptic Ulcers
Gastritis is inflammation of the stomach lining. A peptic ulcer is an open sore in the stomach or the first part of the small intestine. Both can cause a burning or gnawing pain in the upper middle abdomen, sometimes worse when you are hungry or a couple of hours after eating. Some people wake at night with pain. Causes include Helicobacter pylori infection, regular use of NSAIDs like ibuprofen or naproxen, heavy alcohol use, and severe stress from illness. If pain comes with black stools, vomiting blood, or sudden severe pain, get urgent help. For milder recurring symptoms, gastritis treatment strategies to soothe your stomach can explain acid suppression, testing for H. pylori, and food triggers worth reviewing.
3. Gallstones and Biliary Pain
Gallstones are hard deposits in the gallbladder. They often cause pain in the upper right abdomen, sometimes spreading to the right shoulder or between the shoulder blades. The pain may build after a fatty meal such as fried chicken, pizza, or a creamy dessert, then fade over a few hours. A stone that blocks a duct can trigger more serious problems: steady severe pain, fever, nausea, yellowing of the eyes or skin, or tea-colored urine. Those signs need same-day medical care. Many people have silent gallstones and never need surgery. The decision depends on symptoms, test results, and risk factors such as rapid weight loss, pregnancy, or a family history of gallstones.
4. Chronic Constipation and Functional Bowel Problems
Constipation is not just about missing a daily bowel movement. Doctors often define it as fewer than three bowel movements a week, hard stools, straining, or a feeling of incomplete emptying. When stool backs up, the colon can stretch and produce crampy lower abdominal pain, bloating, and a heavy feeling. Some people alternate between constipation and loose stools, which can be confusing. Long-term constipation has many drivers: low fiber intake, dehydration, medication side effects, thyroid problems, pelvic floor dysfunction, and slow transit through the bowel. If this sounds familiar, the guide to top causes of chronic constipation and how to tell which one is yours breaks down the patterns and when testing makes sense.
5. Inflammatory Bowel Disease (IBD)
Crohn’s disease and ulcerative colitis are immune-related conditions that cause inflammation in the digestive tract. Pain is often persistent rather than a one-off cramp. It may come with diarrhea, urgency, fatigue, weight loss, mouth ulcers, or blood in the stool. Crohn’s can affect any part of the gut and may cause pain in the lower right abdomen. Ulcerative colitis typically starts in the rectum and causes bloody diarrhea and cramping. Symptoms can be mild for months, then flare. Because IBD can lead to complications such as strictures, fistulas, and nutrient deficiencies, persistent pain with these signs deserves a gastroenterology review rather than repeated over-the-counter remedies.
6. Gynecologic Causes
In people with a uterus and ovaries, persistent lower abdominal or pelvic pain can come from endometriosis, fibroids, ovarian cysts, pelvic inflammatory disease, or adhesions. Endometriosis pain often worsens around periods and during sex, and it can make bowel movements painful. Fibroids may cause heaviness, pressure, heavy bleeding, or frequent urination. Ovarian cysts are often harmless and go away, but a twisted cyst can cause sudden severe pain, nausea, and vomiting. Pregnancy-related problems, including ectopic pregnancy, are emergencies. A good history matters here: cycle timing, bleeding pattern, pain during sex, and fertility goals all shape the next steps.
7. Problems Outside the Gut
Not all abdominal pain starts in the digestive tract. Kidney stones can cause waves of severe pain that begin in the flank and move toward the groin, often with blood in the urine. Urinary tract infections can produce lower abdominal pressure and burning. In older adults or people with diabetes, heart problems may show up as upper abdominal pain, nausea, or indigestion rather than classic chest pressure. That is why unexplained abdominal pain with sweating, shortness of breath, or pain spreading to the jaw or arm should never be brushed off. The guide to heart attack warning signs, treatment, and prevention is worth reading if those symptoms appear, especially with a history of heart disease.
Signs That Need Urgent Medical Care
Most persistent abdominal pain is not an emergency, but some patterns are. Get urgent medical help if you notice any of the following:
Call emergency services now if you have
- Pain that is sudden, severe, or makes you double over
- Fever, chills, or worsening pain with a rigid or tender abdomen
- Vomiting blood, black tarry stools, or blood in stool
- Yellowing of eyes or skin, dark urine, or pale stools
- Unexplained weight loss, night sweats, or a new lump
- Pain with pregnancy, fainting, dizziness, or shoulder-tip pain
- Chest pressure, shortness of breath, sweating, or pain spreading to the jaw or arm
This list does not cover every emergency. If you are unsure, call a nurse line or go to urgent care. Pain that wakes you from sleep or keeps returning every few weeks deserves a real appointment, not another antacid.
What to Track Before Your Appointment
A useful appointment starts with a short record, not a perfect one. Write down where the pain starts and whether it moves. Note whether it is burning, crampy, sharp, or pressure-like. Record how long each episode lasts and what makes it better or worse: food, bowel movements, periods, stress, lying flat, or walking. List all medications and supplements, including ibuprofen, antacids, laxatives, and iron pills. Bring recent test results and note any family history of colon cancer, IBD, gallstones, or ovarian problems. If you can, track bowel movements and meals for a week. Photos of bloating can help too. That kind of detail often saves time and helps your clinician choose the right tests, whether that means blood work, stool tests, an ultrasound, or a referral.
