Heartburn Causes. Heartburn is actually a symptom of GERD (gastroesophageal reflux disease), and is caused by acid refluxing back into the esophagus. Risk factors include those that increase the production of acid in the stomach, as well as structural problems that allow acid reflux into the esophagus.
Renal Colic Symptoms. Back pain is in the foreground. Back pain is intense, appears abruptly on one side and may radiate to the abdomen, the iliac fossa (above the groin) and genitals. The pain can vary, with paroxysms and periods of remission but can not find any position that relieves pain.
There are several causes of colitis, including infection, ischemia of the colon, inflammatory bowel disease (Crohn's disease, ulcerative colitis, infectious colitis like C. difficile, or microscopic colitis).
