Gasteroenteritis, also known as the stomach flu, is an intestinal infection that causes diarrhea, abdominal cramps, nausea or vomiting, and fever. It is often the result of contact with an infected person, or by ingesting contaminated food or water.
Everyone experiences diarrhea symptoms at some time. They can be due to something you ate or drank, or can result as a common side effect from such conditions as the flu or irritable bowel syndrome (IBS).
Glaucoma is an eye disease where excess pressure irreparably damages the eye, causing blindness. In the United States, an estimated 2 million people have glaucoma. An equal number of people may have the disease but don’t know it.
