question: I am a 79 year old male. For 2 years now, have had a shunt for hydrocephalus / brain tumor / slow growing / found in 1997/ size of golfball in the right ventricle. I have increasing water retention in legs lately and forgot to take HCHLorathizide for a week. Back on now. Must I expect belly bloating to be a part of life with a shunt?
