Sorry to hear about your friend's condition. If he has retained a lot
of fluids , probably he has distended belly with fluid as well. I am not
sure if he has been on any water pills or diuretics. Elaevation of the legs
will help some but if he has massive ascites
(Fluid in the abdomen) this
may not be enough. Seeping of fluid indicates advanced condition.
He has to be hospitalized, get a complete blood work up , including
tests to make sure he is not going into kidney failure also.
He needs intravenous diuretics , nutritional support and careful medical
supervision to take care of any complications of cirrhosis
or liver coma
In answer to your question , yes, take him as soon as you can.
I wish him well.
