Ulcers damage the lining of the stomach because of bacterial infections or adverse side effects of medications such as aspirin, ibuprofen or naporoxen, according to the National Digestive Diseases Information Clearinghouse. Spicy foods and stress may aggravate ulcers, but do not cause them. Antibiotics or antacids usually alleviate problems long enough for minor ulcers to heal.

Acid Reflux

Heartburn or acid indigestion results in stomach acid backing up into the esophagus to create a burning sensation or sour taste in the mouth. Gastroesophageal reflux disease (GERD) affects people who suffer acid reflux symptoms more than twice a week. Acid reflux occurs because the lower esophageal sphincter does not close properly. Some people may get more bouts of heartburn from certain foods, but each individual has different reactions to particular foods. Cigarette smoking contributes to heartburn by causing the esophageal sphincter to relax.

Celiac Disease

Celiac disease can affect children or adults. Symptoms include diarrhea, bloating, abdominal pain, skin rash or a thinning of bones. In children it can cause growth failure. People with the disease are advised to eliminate foods with gluten, a protein that is found in wheat, rye and barley. Gluten damages the lining of the small intestine for people with the disease.

Irritable Bowel Syndrome

Irritable bowl syndrome affects the muscles in the intestines. It can cause gas, abdominal pain, diarrhea or constipation. The syndrome can be painful and uncomfortable. It usually does not lead to further diseases. Most people can control symptoms through diet, stress management and medication.

Inflammatory Bowel Diseases

Inflammatory bowel diseases include Crohn's disease and ulcerative colitis. It leads to severe bowel problems, abdominal pain and malnutrition. Crohn's disease and ulcerative colitis can be painful and debilitating. Medication can eliminate symptoms and prevent flare-ups. Surgery may be needed in some cases to repair the colon.


The disease occurs when pouches in the large intestine become infected and inflamed, according to the American Academy of Family Physicians. Symptoms may include severe abdominal pain often in the lower left side of the abdomen, constipation, diarrhea, nausea or fever. People with the disease are advised to eat more fiber to help with proper digestion.
