Crohn's disease can cause a range of symptoms depending on what portion of the bowel is affected.
It can cause diarrhea, blood in stool, ulcers in mouth, weight loss, bowel obstruction with vomiting, and sores or fistful as around the anus. It can cause anemia and low protein. Most of the times symptoms develop over time. Ask your internist or see a gastroenterologist if crohn's seems likely.
