Portal Hypertension: Causes, Symptoms, and Treatment

What kind of doctor treats Portal Hypertension?
A hepatologist (a liver doctor) or a gastroenterologist (a doctor who treats the digestive system) usually treats portal hypertension, often with help from a primary care doctor. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is portal hypertension?
Portal hypertension means high pressure in the blood vessels of the liver. It is the main complication of cirrhosis. Cirrhosis is scarring of the liver that results in poor liver function.
Symptoms
People with chronic liver disease and esophageal varices may have no symptoms. Problems linked to portal hypertension can include:
- Varices, which are enlarged veins in the esophagus (the food pipe) that may rupture and bleed.
- Varices in the upper part of the stomach, called gastric varices.
- Ascites, which is a buildup of fluid in the belly.
- Hepatic encephalopathy, which means mental confusion or a change in how alert you are.
A small amount of bleeding from varices may only cause dark or black streaks in the stool. Larger amounts of bleeding can cause:
- Black, tarry stools or bloody stools.
- Lightheadedness and paleness.
- Vomiting blood.
The liver disease behind portal hypertension can also cause other signs. These include tiredness. They also include easy bruising. Yellow skin or eyes, called jaundice, can also happen.
Causes and who gets it
Cirrhosis is by far the most common cause of portal hypertension. Cirrhosis is most often the end result of long-term liver damage. Common causes of chronic liver disease in the United States include hepatitis B or C infection and alcohol overuse. Fat buildup in the liver that is not caused by alcohol is another common cause.
Portal hypertension can also come from blood clots in the portal vein or the splenic vein. An infection called schistosomiasis is another cause that does not involve cirrhosis.
How doctors diagnose it
In people with cirrhosis, a doctor may find an enlarged liver or spleen during an exam. Blood tests such as liver function tests measure liver function. CT and MRI scans of the belly can check for liver damage. An ultrasound of the belly is another test.
An upper endoscopy uses a camera on a flexible tube to look at the esophagus and stomach. This test can check for abnormal veins in the esophagus or stomach. Some providers suggest this test for people who are newly diagnosed with cirrhosis.
In cirrhosis, doctors can also measure pressure in the liver veins using the HVPG. An HVPG above 5 mmHg means portal hypertension.
Treatment
When varices bleed, the goal of treatment is to stop the bleeding as soon as possible. Bleeding must be controlled quickly to prevent shock and death.
A provider can pass an endoscope, which is a tube with a small light, into the esophagus. A rubber band can be placed around the bleeding veins, which is called banding. Banding is the most common endoscopic treatment for esophageal varices. A clotting medicine can also be injected into the varices. A medicine that tightens blood vessels may be given through a vein.
Once the bleeding stops, medicines called beta blockers can lower pressure in the portal vein and the risk of bleeding. Banding can also be done during an upper endoscopy to prevent future bleeding.
A procedure called TIPS creates new connections between two blood vessels in the liver. This can lower pressure in the varices and stop bleeding from happening again. The shunt can send more toxins to the brain, which can cause confusion and other mental changes.
Treating the causes of liver disease may prevent bleeding. In cirrhosis, care also includes drinking no alcohol. Water pills, called diuretics, help get rid of fluid buildup. A doctor can also remove fluid from the belly, which is called paracentesis. When cirrhosis reaches end-stage liver disease, a liver transplant may be needed.
When to see a doctor
Contact your provider if you develop symptoms of cirrhosis. Go to the emergency room or call 911 right away if you vomit blood or have black, tarry stools. If you have cirrhosis, also get emergency medical help right away if you have any of these:
- Belly or chest pain.
- Belly swelling that is new or suddenly gets worse.
- Confusion or a change in alertness.
- Rectal bleeding.
- Shortness of breath.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either kind of doctor can review your liver health, check your medicines, and help you keep up with visits. They can also coordinate care with a liver specialist.
Common questions
What causes portal hypertension?
Cirrhosis is by far the most common cause. Blood clots in the portal vein or splenic vein can also cause it.
Can portal hypertension cause bleeding?
Yes, it can cause enlarged veins called varices that may tear and bleed. Bleeding often comes back with or without treatment.
Does portal hypertension always cause symptoms?
No, some people have no symptoms. Small amounts of bleeding may only cause dark streaks in the stool.
Will I need a liver transplant?
Some people may. A liver transplant may be needed when cirrhosis reaches end-stage liver disease. People with bleeding varices from liver disease may need more treatment for their liver disease, including a liver transplant.
