Giardiasis - Giardia is the name of a microscopic parasite that can live in the human bowel. The sickness that this parasite causes is called giardiasis. Some symptoms of giardiasis are diarrhea, belching, gas and cramps. Although these problems are very unpleasant, the illness isn't usually dangerous.
Giardiasis is easy to catch if you drink untreated spring water or stream water. Many animals carry Giardia in their feces and may introduce this parasite into rivers, streams and springs in rural areas. Infected stream water may look clean and safe when it really isn't. City water may also be infected if sewer lines flood or leak. If you travel overseas, you may get giardiasis by drinking water (even tap water) that hasn't been boiled or treated.
Hemorrhoids - hemorrhoids are swollen and inflamed veins in your anus and rectum. They may result from straining when having a bowel movement or the increased pressure on these veins during pregnancy. By age 50, about half of adults deal with the itching, bleeding and pain that often signal the presence of this condition.
Fortunately, effective medications and procedures are readily available to treat hemorrhoids. In many cases this condition may require only self-care and lifestyle changes.
Hepatitis - it is an inflammation of the liver. Inflammation causes soreness and swelling. Hepatitis can be caused by many things. Drinking too much alcohol, abusing drugs and taking some medicines can cause hepatitis. Many viruses can cause hepatitis, too.
There are two main kinds of hepatitis, acute hepatitis and chronic hepatitis. When a person has hepatitis, the liver may become inflamed very suddenly. This is called acute hepatitis. If you have acute hepatitis, you might have nausea, vomiting, fever and body aches. Or you may not have any symptoms. Most people get over the acute inflammation in a few days or a few weeks. Sometimes, however, the inflammation doesn't go away. When the inflammation doesn't go away, the person has chronic hepatitis.
