What should you know about non-cirrhotic portal hypertension?

The portal vein carries blood from the digestive organs towards the liver. If blood flow through the liver or its vessels is obstructed, pressure can rise even when cirrhosis is not present. Causes can include a clot, narrowing, certain medicines, immune conditions, or disorders affecting small liver vessels. Sometimes the cause remains unclear after testing.

Raised pressure may enlarge veins in the oesophagus or stomach, enlarge the spleen, or lower blood-cell counts. Some people have no symptoms until a complication occurs. The diagnosis usually combines blood tests with ultrasound or other scans, and sometimes an endoscopy to look for enlarged veins.

Arrange specialist follow-up so the cause and complications can be assessed. Keep a record of black stools, vomiting blood, abdominal swelling, or new confusion. Take prescribed medicines as directed and tell the clinician about every medicine, supplement, and previous clot. Avoid alcohol if advised and ask before using pain medicines that may increase bleeding risk. Manage related conditions such as Hypertension, obesity, or Obstructive Sleep Apnoea with a clinician-led plan.

Call emergency services for vomiting blood, black or tar-like stools, fainting, severe dizziness, sudden confusion, or marked weakness. Seek prompt care for new abdominal swelling, yellowing of the skin, fever, or worsening pain. Bleeding from enlarged veins can become dangerous quickly and needs hospital treatment.

Ask what is causing the pressure, whether enlarged veins need surveillance or treatment, which medicines to avoid, and how you will be monitored for anaemia, clotting, or spleen enlargement.
