Cirrhosis is where your liver is severely scarred and permanently damaged. While the word cirrhosis is most commonly heard when people discuss alcohol-induced liver disease, cirrhosis is caused by many forms of liver disease.
While fibrosis is reversible there is a point where the damage becomes too great and the liver cannot repair itself. There is no treatment that can cure cirrhosis. If possible, treating the underlying cause of cirrhosis may keep your cirrhosis from getting worse and help prevent liver failure. Successful treatment may slowly improve some of your liver scarring. It is important to avoid things that could damage your liver further like alcohol, certain medications and fatty food. Treatment for someone with cirrhosis often means managing the symptoms of cirrhosis and preventing further damage to avoid liver failure. Doctors treat liver failure with a liver transplant. Someone with cirrhosis is at a very high risk of developing liver cancer. It is very important to receive routine liver cancer surveillance if you have cirrhosis; most people who develop liver cancer have evidence of cirrhosis. Doctors also treat liver cancer with a transplant. It is important to note, people often live with cirrhosis for a long time before the option of liver transplant is discussed.
There is a big difference between liver functioning and disease progression. Our livers are resilient, continuing to function even when they become severely scarred. Because of this, some people may not experience symptoms or have elevated liver enzyme tests even though their liver is damaged. It is important to talk to your doctor about your risks for liver disease so you can receive imaging tests that may help diagnosis liver damage.
Cirrhosis is often categorized as either compensated or decompensated. Someone with compensated cirrhosis doesn’t necessarily look or feel sick. Their symptoms of the disease may be mild or nonexistent even though the liver is severely scarred. Someone with decompensated cirrhosis will feel and appear sick as their liver is struggling to function.
When someone has cirrhosis their liver shrinks and becomes hard, greatly impacting the liver’s ability to process the massive amounts of blood for which it’s responsible. The liver has two sources that supply blood to the liver – the hepatic artery and the hepatic portal vein. The hepatic artery brings oxygen-rich blood into the liver. Blood coming from our digestive system enters the liver through the hepatic portal vein carrying nutrients, medications, or toxins.
When someone has decompensated cirrhosis the scar tissue blocks the blood meant to flow through the portal vein causing an increase of pressure known as portal hypertension. The blood carried in the portal vein is filled with proteins, toxins and other “stuff” meant to be filtered by the liver. The blood unable to enter the liver must find new routes; because the blood is not entering the liver, nutrients, toxins and more from the digestive system does not get properly filtered. Portal hypertension is responsible for symptoms like varices, ascites and encephalopathy. Hepatorenal syndrome can also occur when someone has decompensated cirrhosis.
The increased pressure of portal hypertension causes fluid to seep out and pool in the abdominal cavity. This is called ascites. When large amounts of fluid gather in the belly it can lead to swelling and pain and be very uncomfortable. Ascites can become infected, which can greatly impact the function of your kidneys, and can even be fatal.
Ammonia is a waste product made when our body digests protein. The liver processes the ammonia, breaks it down to something called urea, and sends it to our kidneys to be released in urine. When someone has cirrhosis, ammonia is not eliminated, builds up, travels to the brain, and causes confusion, disorientation, coma, and even death. This is hepatic encephalopathy. Hepatic Encephalopathy (or HE) can be managed with medications that are taken regularly. One of these medications tries to eliminate extra ammonia through increasing the number of bowel movements. The other common medication is a powerful antibiotic which eliminates the bacteria in your digestive system responsible for creating the ammonia.
The liver is the largest filter in the body but works closely with our kidneys to eliminate waste from our bodies. When someone has cirrhosis, they may develop a serious complication where their kidneys begin to progressively fail. This is called hepatorenal syndrome.
Our red blood cells have a substance in them called hemoglobin which is responsible for carrying oxygen. Bilirubin is a yellow chemical found in hemoglobin. Your body builds new cells to replace broken down red blood cells and the old ones are processed in the liver. The breakdown of the old cells releases bilirubin. A healthy liver processes bilirubin out of the body. If the liver cannot successfully do this function, bilirubin builds up in the body and your skin or the whites or your eyes may look yellow. This is called jaundice.
This buildup of bilirubin can also cause someone’s urine to become very dark or their poop to be pale in color. Excess bilirubin is excreted in urine which causes someone’s pee to look very dark and brown, almost like a cola soda. The lack of bilirubin entering the gut causes someone’s stool to be very light in color. Jaundice does not only occur in people with cirrhosis. Many healthy babies have jaundice during the first week of life. Jaundice can also be due to blood diseases, genetic conditions, blockages of bile ducts, infections (like hepatitis A), and even some medications.
When blood cannot flow through the portal vein into the liver it is forced to find new pathways, such as through the veins in the stomach and esophagus. These enlarged veins are called varices. These small veins are not meant to carry so much blood. When overloaded with blood, these veins can balloon, leak blood or even rupture, causing life-threatening bleeding. Varices usually don’t cause any symptoms unless they bleed. Signs of bleeding varices include:
Doctors can view these varices by inserting an endoscope (a thin flexible tube) through your mouth, down to your esophagus and stomach. Endoscopies are very important to avoid varices from bursting and bleeding. Doctors use endoscopies to check on the varices and, if needed, band them, or tie them off, to strangle the vein and keep them from bursting.
