Any type of cancer that begins in the large intestine. Usually begins as small, noncancerous (benign) clumps of cells called polyps that form on the inside of the large intestine. These polyps can become cancerous.

This disorder is caused by painful, swollen blood vessels in the anal canal. Symptoms include pain, itching, and bright red blood after a bowel movement. Constipation and pregnancy are major causes.

This disorder occurs when small pouches form in the wall of your colon and sometimes becomes inflamed. Roughly half of people ages 60 to 80 have this condition. Symptoms include feeling bloated, constipated, or pain in your lower abdomen.

Sore or lesion that forms in the mucosal lining of the stomach, esophagus, or duodenum. Caused by H. pylori (bacteria) and some lifestyle factors may contribute: cigarette smoking, alcohol, stress, certain drugs

Loose, watery, frequent bowel movements when feces pass along colon too rapidly. Caused by infection, poor diet, nervousness, toxic substances or irritants in food.

Caused from eating food containing gluten. Symptoms include diarrhea, bloating, and abdominal pain. Eliminating gluten—a protein in wheat, rye, barley—from your diet is the main treatment

Inflammation of the liver. Can be caused by heavy alcohol use, toxins, some medications, and certain medical conditions. However it is often caused by a virus.

Cause is unknown. Symptoms – abdominal pain, bloating, diarrhea and constipation (alternating). Treatment includes lifestyle changes, diet changes, and medication.

Caused by hardened deposits of bile that can form in your gallbladder. Can go away on its own but may require surgery to remove the gallbladder
