Alcoholism is a serious condition to where your body is addicted to the substance alcohol. Alcohol can literally ruin your body. It kills brain cells, and destroys your liver and kidneys. You can live without a kidney, but not without both. You can get half of a liver transplanted because it grows, but you have to be healthy enough to have the surgery. You can't, however, live without those precious brain cells. They are what makes the body function. Alcoholism is mentioned several times in House MD, but it is never the overall diagnoses because it isn't that much of a mystery.
