Q.What is Cirrhosis of the Liver?
A. Cirrhosis is a slowly progressing disease in which healthy liver tissue is replaced with scar tissue, eventually preventing the liver from functioning properly. The scar tissue blocks the flow of blood through the liver and slows the processing of nutrients, hormones, drugs and naturally produced toxins. It also slows the production of proteins and other substances made by the liver.
According to the American Cancer Society, Cirrhosis is the seventh leading cause of death by disease.
What Causes Cirrhosis?
Hepatitis C, fatty liver and alcohol abuse are the most common causes in the U.S., but anything that damages the liver can cause cirrhosis, including:
- Fatty liver associated with obesity and diabetes.
- Chronic viral infections of the liver (hepatitis types B, C and D; Hepatitis D is extremely rare).
- Blockage of the bile duct, which carries bile formed in the liver to the intestines where it helps in the digestion of fats. In babies, this can be caused by biliary atresia in which bile ducts are absent or damaged, causing bile to back up in the liver. In adults, bile ducts may become inflamed, blocked or scarred, due to another liver disease called primary biliary cirrhosis.
- Repeated bouts of heart failure with fluid backing up into the liver.
- Certain inherited diseases such as:
- Cystic fibrosis.
- Glycogen storage diseases, in which the body is unable to process glycogen, a form of sugar that is converted to glucose and serves as a source of energy for the body.
- Alpha 1 antitrypsin deficiency, an absence of a specific enzyme in the liver.
- Diseases caused by abnormal liver function, such as hemochromatosis, a condition in which excessive iron is absorbed and deposited into the liver and other organs, and Wilson's disease, caused by the abnormal storage of copper in the liver.
Although less likely, other causes of cirrhosis include reactions to prescription drugs, prolonged exposure to environmental toxins or parasitic infections.
Do People Who Drink A Lot of Alcohol Always Get Cirrhosis?
Most people who drink large amounts of alcohol harm their livers in some way; but not all of these people get cirrhosis. Women who are heavy drinkers are at higher risk than men. People who have hepatitis B or hepatitis C are more likely to suffer liver damage from alcohol.
What Are the Symptoms of Cirrhosis?
The symptoms of cirrhosis vary with the stage of the illness. In the beginning stages, there may not be any symptoms. As the disease worsens, symptoms may include:
- Loss of appetite.
- Lack of energy (fatigue) which may be debilitating.
- Weight loss or sudden weight gain.
- Bruises.
- Yellowing of skin or the whites of eyes (jaundice).
- Itchy skin.
- Fluid retention (edema) and swelling in the ankles, legs and abdomen (often an early sign).
- A brownish or orange tint to the urine.
- Light colored stools.
- Confusion, disorientation, personality changes.
- Blood in the stool.
- Fever.
How Is Cirrhosis Diagnosed?
Cirrhosis is diagnosed through several methods:
- Physical exam. During a physical exam, your doctor can observe changes in how your liver feels or how large it is (a cirrhotic liver is bumpy and irregular instead of smooth).
- Blood tests. If your doctor suspects cirrhosis, you will be given blood tests to find out if liver disease is present.
- Other tests. In some cases, other tests that take pictures of the liver are performed such as a computerized tomography (CT scan), an ultrasound, or another specialized procedure called a radioisotope liver/spleen scan.
- Biopsy. Your doctor may decide to confirm the diagnosis by taking a sample of tissue (biopsy) from the liver.
- Surgery. In some cases, cirrhosis is diagnosed during surgery when the doctor is able to see the entire liver. The liver also can be inspected through a laparoscope, a viewing device that is inserted through a tiny incision in the abdomen.
What Complications Are Associated With Cirrhosis?
Complications associated with cirrhosis include:
- Variceal bleeding. Variceal bleeding is caused by portal hypertension, which is an increase in the pressure within the portal vein (the large vessel that carries blood from the digestive organs to the liver). This increase in pressure is caused by a blockage of blood flow through the liver as a result of cirrhosis. Increased pressure in the portal vein causes other veins in the body to enlarge (varices), such as those in the esophagus and stomach, to bypass the blockage. These varices become fragile and can bleed easily, causing severe hemorrhaging and fluid in the abdomen.
- Confused thinking and other mental changes (hepatic encephalopathy). Hepatic encephalopathy most often occurs when cirrhosis has been present for a long time. Toxins produced in our intestines are normally detoxified by the liver, but once cirrhosis occurs, the liver cannot detoxify as well. Toxins get into the bloodstream and can cause confusion, changes in behavior and even coma.
Other serious complications of cirrhosis include:
- Kidney failure.
- Reduced oxygen in the blood.
- Diabetes.
- Changes in blood counts.
- Increased risk of infections.
- Excessive bleeding and bruising.
- Breast enlargement in men.
- Premature menopause.
- Loss of muscle mass.
Most of these complications can initially be treated with medicines or dietary changes. Once treatment for these complications becomes ineffective, a liver transplant is considered. Almost all of the complications can be cured by liver transplantation; however, in many circumstances, careful management can reduce the harmful affects of cirrhosis, which can delay or even prevent the need for a liver transplant.
How Is Cirrhosis Treated?
Although there is no cure for cirrhosis, there are treatments available that can stop or delay its progress, minimize the damage to liver cells and reduce complications.
The treatment used depends on the cause of cirrhosis.
- For cirrhosis caused by alcohol abuse, the person must stop drinking alcohol to halt the progression of cirrhosis.
- If a person has hepatitis, the doctor may prescribe steroids or antiviral drugs to reduce liver cell injury.
- For people with cirrhosis caused by autoimmune diseases, Wilson's disease or hemochromatosis, the treatment varies.
Medications may be given to control the symptoms of cirrhosis. Edema (fluid retention) and ascites (fluid in the abdomen) are treated, in part, by reducing salt in the diet. Drugs called diuretics are used to remove excess fluid and to prevent edema from recurring. Diet and drug therapies can help improve the altered mental function that cirrhosis can cause. Laxatives such as lactulose may be given to help absorb toxins and speed their removal from the intestines.
Liver transplantation may be needed for some people with severe cirrhosis.
How Can I Prevent Cirrhosis?
There are several ways to reduce your risk of developing cirrhosis:
- Don't abuse alcohol. If you do drink alcohol, limit how much you drink and how often. Remember it's not only the heavy drinker who gets cirrhosis. If you drink more than 2 drinks a day, you are increasing your risk. A drink is a 5 oz glass of wine or a 12-oz can of beer or a 1 1/2 oz portion of hard liquor.
- Avoid high-risk sexual behavior such as unprotected sexual contact with multiple partners.
- Be careful around synthetic chemicals, such as cleaning products and pesticides. If you come into contact with chemicals often, wear protective clothing and a facemask.
- Get vaccinated against hepatitis B.
- Eat a well-balanced, low-fat diet and take vitamins.
