What are common causes of chronic abdominal pain?

Chronic abdominal pain lasting more than six months commonly results from irritable bowel syndrome (IBS), inflammatory bowel diseases like Crohn's disease or ulcerative colitis, peptic ulcers, gallstones, chronic pancreatitis, and functional dyspepsia, according to gastroenterology research published by the American Gastroenterological Association.

Irritable Bowel Syndrome (IBS) represents the most frequent cause of chronic abdominal pain, affecting approximately 10-15% of adults in the United States. This functional disorder causes cramping, bloating, and altered bowel habits without visible intestinal damage. The Rome IV criteria, established by the Rome Foundation, define IBS as recurrent abdominal pain occurring at least one day per week over three months.

Inflammatory Bowel Diseases including Crohn's disease and ulcerative colitis cause persistent inflammation in the digestive tract. These autoimmune conditions produce cramping pain, often accompanied by bloody stools, weight loss, and fatigue. The Crohn's and Colitis Foundation reports that over 3 million Americans live with these conditions.

Peptic Ulcers create burning or gnawing pain in the upper abdomen, typically caused by Helicobacter pylori bacteria or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs). The American College of Gastroenterology notes that untreated ulcers can lead to serious complications including bleeding or perforation.

Gallbladder Disease including gallstones and cholecystitis causes pain in the upper right abdomen that may radiate to the back or shoulder. This pain often intensifies after eating fatty meals and affects approximately 20% of American adults over age 65.

Chronic Pancreatitis involves ongoing inflammation of the pancreas, causing deep, boring pain in the upper abdomen that radiates to the back. This condition often develops from long-term alcohol use or genetic factors.

Functional Dyspepsia causes upper abdominal discomfort without identifiable structural abnormalities. Symptoms include early satiety, bloating, and burning sensations after meals.

For example, a 45-year-old woman experiencing cramping lower abdominal pain with alternating constipation and diarrhea for eight months would likely be evaluated for IBS, especially if no red flag symptoms like weight loss or blood in stool are present. Understanding the connection between dietary triggers and symptom patterns becomes crucial for effective management.

Anyone experiencing chronic abdominal pain should consult a gastroenterologist for proper evaluation, as accurate diagnosis requires comprehensive medical assessment including physical examination, laboratory tests, and potentially imaging studies or endoscopy.
