Your liver is your body\u2019s largest internal organ. It sits under your rib cage on the right side of your body. This vital organ supports every other organ in your body and has multiple functions that support your overall health. In fact, this organ is so important that you could only survive one or two days if it shut down.\nSo, what does the liver do? In the following sections, we\u2019ll discuss the importance of the human liver and how to prevent the most common types of liver disease.\nFor more information or to make an appointment please call 412-647-5800 or visit the UPMC Transplant Services website.\nWhat Does Your Liver Do?\nWhere in the Body Is the Liver?\nThe liver sits under your rib cage on the right side of your body. It spans across the mid-line and is protected by the lower ribs.\nWhy Is the Liver So Important?\nSplit into two sections, the right and left lobes, the liver\u2019s main function is to filter the blood that comes from your digestive tract before passing it along to the rest of your body. It is responsible for more than 500 important functions that include:\n\nHelping your blood clot\nBreaking down alcohol, chemicals, and other drugs\nMaking glucose, a sugar that your body can use for a quick burst of energy\n\nAt any given time your liver contains about 10 percent of your body\u2019s total blood volume, and it filters 1.4 liters of blood per minute.\nSo, what does the liver do? Your liver is your only organ that can regenerate, or regrow, itself. The human liver has the greatest regenerative capacity of any of the organs within the body. As a result, you can donate part of your liver to someone else, and have both your liver and the recipient\u2019s liver grow to near full size again, regaining its function.\nSymptoms of Liver Disease\nSee a doctor if you have any of the following symptoms, as they may be indications of liver problems:\n\nYellowing of the skin or eyes (jaundice)\nAbdominal pain or swelling\nSwelling of the legs or ankles\nItchy skin\nDark colored urine\nPale, bloody, or tar-colored stool\nChronic fatigue\nNausea or vomiting, diarrhea\nDecrease or loss of appetite\nBruising easily\n\nTypes of Liver Disease\nAs one of the major organs in your body, your liver can suffer many types of liver problems that can harm your overall health if not treated. One of the most common types of liver conditions is cirrhosis, which happens when your liver becomes scarred, and cannot work in a normal way.\nOther types of liver disease that can affect normal liver function include:\n\nViral Hepatitis A, B, C, and D\nWilson\u2019s Disease\nLiver disease due to alcohol\nLiver Cancer\nFatty Liver\n\nTreatment for Liver Disease\nDepending on your diagnosis there may be treatment options, such as lifestyle changes (losing weight or cutting out alcohol), medication, or surgery.\nLiver Transplant\nAlthough treatment may be available for liver disease, if the damage is too severe you may need a liver transplant. Your doctor will refer you to a transplant center for a thorough evaluation of your condition, which includes a series of tests and assessments by a team of experts. If deemed necessary, you will be placed on the national transplant waiting list.\nWhile a liver transplant is a major surgery that has risks, many people go on to live full, active lives after a transplant. Your transplant team will talk with you about what to expect before and after your surgery, and for ongoing follow-up care. UPMC has one of the oldest and largest liver transplant programs in the United States.
