Intermittent abdominal cramping, a constant stomach ache, frequent bouts of diarrhea that may include bloody stools, fever and unintended weight loss are common symptoms of Crohnﾒs disease, according to WebMD. Anemia, anal fissures and loss of appetite are also possible symptoms of Crohnﾒs disease.
Due to the ulcers and inflammation that Crohn's disease causes in the intestines, the body does not adequately absorb the nutrients in food, and patients are susceptible to vitamin and mineral deficiencies, explains WebMD. Crohnﾒs disease also increases the risk of anemia if there is blood loss in the stools, and kidney stones and gallstones are often associated with this inflammatory bowel disease. If scar tissue forms in the intestines due to prolonged periods of inflammation, bowel obstructions and strictures can occur that often require surgical treatment. Fistulas may form between the intestines and other organs or between intestines and the skin if the ulcers break through the intestinal walls, sometimes resulting in severe infections.
While Crohnﾒs disease most often affects the last part of the small intestine and the first part of the large intestine, it can occur in any area of the digestive tract, notes WebMD. When Crohn's disease has been present in the rectum and anus for eight years or more, the risk of cancer increases. Crohnﾒs disease is a chronic condition that produces mild symptoms in some patients and life-threatening symptoms and complications in others.
