In short
- Breathlessness has many causes. The liver is one of the less obvious ones.
- Fluid build-up from advanced liver disease can press on the lungs.
- Sudden or severe breathlessness is an emergency.
How the liver reaches the lungs
In advanced liver disease, fluid can collect in the abdomen and sometimes around the lungs, leaving less room to breathe. Less commonly, changes in the blood vessels of the lungs stop oxygen passing into the blood efficiently, so a person feels breathless especially when standing or walking. Anaemia and a weak heart, both more common with liver disease, add to it.
What the doctor will want to know
When it started. Whether it is worse lying flat or on exertion. Whether there is swelling in the legs or abdomen, fever, chest pain or a cough. What medicines you take, including water tablets. Your most recent liver reports. From there, an oxygen reading, a chest X-ray or an ultrasound of the abdomen usually points to the cause.
When not to wait
Breathlessness that comes on suddenly, is severe, or comes with chest pain, blue lips, confusion or coughing blood needs the nearest emergency department now. A chamber appointment can follow once you are safe.
