Whenever i eat meat, i get more thirsty & end up drinking lots of water, yet i lose the urge to pee for many hours, like retaining all the water, why?

Intestine absorbs it: To digest foods like meat, water dissolves the solids and travels through the system slowly while nutrition is extracted leaving the waste. Hopefully you are not retaining, but using the water until the job is done.
