Causes of lower bowel cramping include diverticulitis and Crohn's disease, says WebMD. In diverticulitis, little pouches in the intestinal lining caused diverticula become inflamed.

Crohn's disease is a condition where ulcers develop in the gastrointestinal tract, usually in the last part of the small intestine and the first part of the colon, claims WebMD. It is an autoimmune disease where the body's own immune system attacks it. In this case, doctors believe the immune system attacks the bacteria normally found in the gut.

An intestinal obstruction can be caused by anything from tumors, severe constipation, scar tissue, a twisted or telescoped intestine, or temporary paralysis caused by surgery, says Healthline. Besides cramping, symptoms include loss of appetite, nausea, vomiting, diarrhea, swelling and bloating. It is important that the cause of an intestinal obstruction be discovered and treated, for the condition can be fatal.

Irritable bowel syndrome is not fatal, but its symptoms are often frustrating and mimic symptoms of more serious diseases, says Mayo Clinic. Besides cramps, they include mucus in the stool, bloating, gas, and constipation or diarrhea.
