My best-friend (sister) is diabetic with conditions associated with many in-patient hospital visit s, coupled with kidney failure (diagnosed) water retention through her legs and sometimes chest pains. However, another trip will be had Febuary 11th, 2014 @ approx.: on or about 9 am to 11 am, together with her age of over-weight 340 lbs- age 62. What, if anything, can you recommend, medications approved by FDA or Medical Journals success reasonably prescribed with this type-2 diabetes, high-leveled water retention in her legs that can be alleviational to her condition because she is rady to give up on life. Additionally, what health medical specialist should she visit for those above-indicated conditions. Scared To Lose My Favourite Older Sister Life
