Hi. My brother has liver disease,has ascites ,huge bloated stomach ankles.He is yellow not much appetite,sleeps a lot, is still drinking and cant walk properly.His memory is affected .I know he is not a well person.As i dont live close to him i can only assume his life is limited.My concern is how dangerous is it for him to fly?He is supposed to be flying next week for the first time.He has struggled to get insured and the doctor ok,d him a few months back but he hasnt been back to see him since.It worries me that the flight will kill him.He is now in a wheelchair,very depressed but wants to take his family away as they have never been abroad or had a honeymoon.The dr told him a few months ago he would need to go in hospital to have the fluid drained but he hasnt bothered going back to the doctor,claiming he cant get an appointment.I am worried he is going to die on the plane with the air pressure.Iam grateful for any advice.He has just turned 55 and has been a heavy drinker all his life. Thank you
