Conditions that cause abdominal pain
A variety of medical conditions -- from migraines to lead poisoning -- can cause abdominal pain. Some of them, such as gastroenteritis and constipation, are relatively common; others, such as Crohn’s disease, ulcerative colitis and ulcer disease, are more unusual.
Appendicitis. Abdominal pain caused by appendicitis (inflammation of the appendix) frequently, but by no means always, begins near the bellybutton and gradually moves down and to the right; moving or being touched in the area typically aggravates it. Fever, nausea and vomiting or diarrhea may accompany the pain.
Gastroenteritis. Infections involving the gastrointestinal tract can be quite painful and are frequently accompanied by diarrhea and vomiting.
Urinary tract infections. Pain associated with urinary tract infections usually involves the lower mid-abdomen or pelvic area. Children with UTIs may need to go to the bathroom more frequently than usual and may complain of pain or burning when they urinate.
Crohn’s disease. This inflammatory condition of the gastrointestinal tract causes repeated bouts of diarrhea and abdominal pain, ranging from mild to severe. Children with Crohn’s can suffer delayed development and stunted growth.
Ulcerative colitis. This inflammatory condition of the large intestine can also cause recurrent diarrhea and abdominal pain. Other common symptoms include loss of appetite and weight loss.
Irritable bowel syndrome. This digestive disorder causes recurrent abdominal cramping. Bloating, gas, diarrhea and constipation -- or some combination of these problems -- are also frequently present. The pain often gets worse with eating and improves after passing gas or stool.
Ulcer disease. Ulcer pain is typically located in the mid-upper part of the abdomen or around the bellybutton. The pain often occurs at night or in the early-morning hours and is frequently triggered by eating.
