Frequently asked questions
Why does liver disease cause a swollen tummy?
A scarred liver raises pressure in its blood vessels and lowers protein in the blood, so fluid leaks into the tummy. Treating the liver and lowering salt help control it.
Is draining the fluid a permanent fix?
Draining relieves symptoms, but the fluid usually returns unless the underlying cause is treated. Diet, diuretics and treating the liver are needed alongside.
