typing is useful because it helps people do things easier. it helps people because it just does and what if someone didnt have good handwriting that would be very rude to others ok. Portal or nutritional cirrhosis is the form of the disease most common in the United States. About 30-50% of all cases of cirrhosis are this type. Nine out of every 10 people who have nutritional cirrhosis have a history of alcoholism. Portal or nutritional cirrhosis is also called Laënnec's cirrhosis.
Biliary cirrhosis is caused by intrahepatic bile-duct diseases that impede bile flow. Bile is formed in the liver and is carried by ducts to the intestines. Bile then helps digest fats in the intestines. Biliary cirrhosis can scar or block these ducts. It represents 15-20% of all cirrhosis.
Various types of chronic hepatitis, especially hepatitis B and hepatitis C, can cause postnecrotic cirrhosis. This form of the disease affects up to 40% of all patients who have cirrhosis.
Disorders like the inability to metabolize iron and similar disorders may cause pigment cirrhosis (hemochromatosis), which accounts for 5-10% of all instances of the disease.
Causes and symptoms
Long-term alcoholism is the primary cause of cirrhosis in the United States. Men and women respond differently to alcohol. Although most men can safely consume two to five drinks a day, one or two drinks a day can cause liver damage in women. Individual tolerance to alcohol varies, but people who drink more and drink more often have a higher risk of developing cirrhosis. In some people, one drink a day can cause liver scarring.
Chronic liver infections, such as hepatitis B and particularly hepatitis C, are commonly linked to cirrhosis. People at high risk of contracting hepatitis B include those exposed to the virus through contact with blood and body fluids. This includes healthcare workers and intravenous (IV) drug users. In the past, people have contracted hepatitis C through blood transfusions. As of 2003, cirrhosis resulting from chronic hepatitis has emerged as a leading cause of death among HIV-positive patients; in Europe, about 30% of HIV-positive patients are coinfected with a hepatitis virus.
Liver injury, reactions to prescription medications, exposure to toxic substances, and repeated episodes of heart failure with liver congestion can cause cirrhosis. The disorder can also be a result of diseases that run in families (inherited diseases) like:a lack of a specific liver enzyme (alpha1-antitrypsin deficiency) the absence of a milk-digesting enzyme (galactosemia) an inability to convert sugars to energy (glycogen storage disease) an absorption deficit in which excess iron is deposited in the liver, pancreas, heart, and other organs (hemochromatosis) a disorder characterized by accumulations of copper in the liver, brain, kidneys, and corneas (Wilson's disease)
Obesity has recently been recognized as a risk factor in nonalcoholic hepatitis and cirrhosis. Some surgeons are recommending as of 2003 that patients scheduled for weight-reduction surgery have a liver biopsy to evaluate the possibility of liver damage.
Poor nutrition increases a person's risk of developing cirrhosis. In about 10 out of every 100 patients, the cause of cirrhosis cannot be determined. Many people who have cirrhosis do not have any symptoms (often called compensated cirrhosis). Their disease is detected during a routine physical or when tests for an unrelated medical problem are performed. This type of cirrhosis can also be detected when complications occur (decompensated cirrhosis).
Symptoms of cirrhosis are usually caused by the loss of functioning liver cells or organ swelling due to scarring. The liver enlarges during the early stages of illness. The palms of the hands turn red and patients may experience: constipation diarrhea dull abdominal pain fatigue indigestion loss of appetite nausea vomiting weakness weight loss
As the disease progresses, the spleen enlarges and fluid
