Early treatment may help alleviate symptoms. Page ContentQ: I've been having stomach issues and I'm worried I might have Crohn's disease. What are the symptoms?"Crohn's disease is a painful and exhausting illness for many patients," says Hassan Dakik, M.D., a Gastroenterology specialist at Kelsey-Seybold Clinic. "The only way to know for sure you have Crohn's disease is to visit your doctor, but there are obvious signs and symptoms."Crohn's disease is a chronic inflammatory condition of the gastrointestinal tract. It most commonly affects the end of the small bowel and the beginning of the colon, although it may affect any part of the gastrointestinal tract. Dr. Dakik says if you have this disease, you may experience the following symptoms:DiarrheaFever and fatigueAbdominal pain and crampingBlood in your stoolMouth soresReduced appetite and weight lossPain or drainage near or around the anus "Crohn's disease can be caused by a number of factors including genetics, an overactive immune system and your personal environment, such as living in an urban area. There's no cure, but early treatment may help alleviate symptoms," Dr. Dakik says.Because no one treatment works for all Crohn's sufferers, doctors will typically try a combination of treatments including drug therapy or surgery in severe cases.Anti-inflammatory medications and immune system suppressors are usually the first step in treatment."We first try to suppress the responses in your immune system that are causing your symptoms," Dr. Dakik explains. "If drug therapy and other treatments don't provide relief, surgery may be recommended to remove a damaged portion of the digestive tract. Surgery, however, won't cure Crohn's disease, which often recurs," cautions Dr. Dakik.
