Your liver is an amazing organ. It makes a fluid called 'bile' that helps us digest the fatty foods we eat. But in someone with a condition called Primary Biliary Cholangitis (PBC), the delicate ducts that carry this bile are damaged. This causes the bile to not flow properly and become blocked inside the liver. Over time, this blocked bile can harden into stones and cause infections. Eventually, this bile backs up and causes scarring inside the liver. This is the basic nature of PBC.
But don't worry. There are good medications that can help remove bile from the liver and reduce the formation of these scars. However, if you don't treat PBC properly, or if the disease becomes a little more severe, some complications can occur. Today, we'll talk about the most common complications of PBC and how to manage them.

Cirrhosis, a serious condition
Cirrhosis is when healthy cells in your liver are replaced by scar tissue. Simply put, the liver gradually hardens into a stone. This condition occurs in the final stages of PBC. By this time, the liver has already been severely damaged.
Cirrhosis is a serious condition that we need to be aware of, as it can lead to serious conditions like liver failure and liver cancer.
In the past, PBC was called 'primary biliary cirrhosis'. This is because of how closely related the complication of cirrhosis is to this disease.
How is this treated?
Your doctor will prescribe medication to control this condition.
- Often, the first treatment is a medication called ursodeoxycholic acid (Ursodiol) . This works by removing bile from the liver and reducing damage to the liver.
- If you don't feel much better with this medicine alone, your doctor may recommend taking a medicine called obeticholic acid (Ocaliva) in addition to it.
- In addition, new drugs such as elafibranor (Iqirvo) and seladelpar (Livdelzi) are now approved for use with ursodeoxycholic acid.
- Another option is a class of drugs called fibrates . Although these are actually approved to lower blood fats (lipids), they have been found to work very well in PBC patients who do not respond well to ursodeoxycholic acid. In this way, when a doctor uses a drug for a condition other than the one for which it was approved, we call it 'off-label' use.
However, if, despite all these treatments, the scar tissue in the liver becomes too much and the liver becomes unable to function, the only solution is a liver transplant . This involves removing your damaged liver and replacing it with a liver from a healthy donor.
Increased pressure in a vein in the liver (Portal Hypertension)
This is another serious complication. Let's understand this. We have a main blood vessel that brings blood to our liver. This is what we call the 'portal vein'.
Now, when scar tissue forms inside the liver due to the condition of cirrhosis that we talked about earlier, the flow of blood through this 'portal vein' is obstructed. Just like a traffic jam on a road, the blood cannot flow properly and gets stuck inside that vein. As the blood accumulates like this, the pressure inside that vein gradually increases. Doctors call this condition portal hypertension .
Why is this dangerous? This high pressure can cause the delicate blood vessels inside the body to burst, causing internal bleeding . Therefore, it is very important to treat this quickly.
Let's simply understand these two complications from the table below.
| Complication | Simply put... | Main Risk |
|---|---|---|
| Cirrhosis | Formation of scar tissue instead of healthy liver tissue (liver stones). | Liver Failure and Liver Cancer. |
| Portal Hypertension | Cirrhosis causes the veins that bring blood to the liver to become blocked, increasing the pressure there. | Internal bleeding. |
What are the treatments for this?
Your doctor may prescribe medications, such as beta-blockers, to reduce the pressure in this 'portal vein.' These can temporarily control your blood pressure.
But remember, the only permanent treatment for portal hypertension is a liver transplant . This is because the primary cause of this is liver damage caused by cirrhosis. Since the damage cannot be repaired, the final solution is to remove the damaged liver and replace it with a new one.
PBC is a disease that can be well controlled with proper medical treatment and advice. Therefore, if you have this disease, do not panic, stay in regular contact with your doctor, and follow the prescribed treatment exactly. That is the best way to stay safe from such complications.
💡 Take-Home Message
- Primary Biliary Cholangitis (PBC) is a disease that damages the delicate ducts in the liver that carry bile.
- If this disease is not treated properly, serious complications such as cirrhosis and portal hypertension can occur.
- Cirrhosis is a condition in which scar tissue builds up in the liver, leading to liver failure and even cancer.
- Portal hypertension is an increase in pressure in the vein that carries blood to the liver. This can cause bleeding inside the body.
- If you have PBC, always talk to your doctor about anything you are concerned about . It is very important to take your medications exactly as prescribed and follow your doctor's instructions.
- In many cases, the final solution may be a liver transplant.
