my husband had a prostate biopsy 3 weeks ago and he is due for an appointment soon, he was fine during and after the proceedure, had anti biotics as well and a few days later he began to loose his appetite, get very lethargic and not bothered, he didnt drink as much as he should and got very dehydrated , now we are monitoring his fluids all the time and he s a tad better, still no interest in food or anything,, he has had liquid meals , dont know what to do really
