6. Inflammatory Bowel Disease
Inflammatory bowel disease is a collective term for inflamed intestines. It is thought to be caused by the immune system overreacting and causing inflammation and bowel injury. It comes and goes, so the pain will not always be present. But the abdominal cramps and pain can be debilitating.
IBD seems to have a link to cigarette smoking, use of nonsteroidal anti-inflammatories, and possibly a diet high in fat or refined foods. IBD puts you at risk for certain cancers, liver damage, and blood clots.
