What is your liver?
Your liver is a football-sized organ on the right side of your belly, just below your ribs. It has many important jobs:
To make a liquid (bile) that helps your body digest fat
To process nutrients from your digestive tract
To make proteins that help your blood clot
To help break down medicines and poisons so your body can get rid of them

What is cirrhosis of the liver?
Cirrhosis is a disease in which scar tissue replaces normal liver tissue. The scar tissue grows when your liver is damaged repeatedly over time.
Cirrhosis is caused mainly by drinking too much alcohol for a long time, having viral hepatitis Chronic Hepatitis Chronic hepatitis is inflammation (swelling) of the liver that lasts for 6 months or longer. Chronic hepatitis usually develops from acute hepatitis but you may not know you had acute hepatitis... read more , or having a buildup of fat in your liver (fatty liver Fatty Liver Fatty liver is an abnormal accumulation of certain fats (triglycerides) inside liver cells.

Symptoms include not feeling hungry, weight loss, and feeling weak and tired all over
Doctors can sometimes treat symptoms and problems of cirrhosis, but the damage to your liver is permanent
What are the complications of cirrhosis?
Severe cirrhosis that goes on for a long time can cause several problems:
Portal hypertension Portal Hypertension The portal vein is the large blood vessel that brings blood from your intestines to your liver. Hypertension is a medical term for high blood pressure. So, portal hypertension is high blood... read more (high blood pressure develops in the veins that connect the intestines to the liver)
Liver failure causes many serious complications:
Brain dysfunction (your brain won't work properly)
Difficulty digesting and absorbing food
Portal hypertension causes blood to back up in the veins connected to the liver. These veins may enlarge and twist. The veins at the lower end of the esophagus, in the stomach, or in the rectum may be affected. Enlarged, twisted veins are fragile and prone to bleeding, so you may:
Vomit large amounts of blood
Pass a lot of blood from your rectum
If you bleed slowly and it continues for a long time, you may have a low blood count (anemia Anemia Due to Excessive Bleeding Anemia due to excessive bleeding results when loss of red blood cells exceeds production of new red blood cells.

How can doctors tell if I have cirrhosis?
Your doctor will suspect you have cirrhosis if you drink too much or have hepatitis and have some of the symptoms listed above. To tell if you have cirrhosis, doctors will:
Do blood tests to see how well your liver is working (there's no blood test that can tell whether you actually have cirrhosis)

How do doctors treat cirrhosis?
There is no cure for cirrhosis. The liver damage is permanent. Doctors will treat your symptoms. You can also help keep the cirrhosis from getting worse by doing the following:
Stop drinking alcohol, if you were drinking too much
Avoid medicines that stress the liver (such as acetaminophen)
Eat foods that are good for you

Give you certain medicines called beta-blockers to lower the pressure in the liver veins
Look down your throat with a flexible scope and close off the enlarged veins by injecting them with a substance or putting special rubber bands around them
If those things don't work, your doctor may put a thin plastic tube in the veins of your liver to re-route the blood and lower the pressure.
If your liver is very bad and barely working, you may need a liver transplant Liver Transplantation Liver transplantation is the surgical removal of a healthy liver or sometimes a part of a liver from a living person and then its transfer into a person whose liver no longer functions.
