First off im 22 yrs old. generally in good health. The past 3 months since my umbilical hernia repair i had done.. ive been suffering from severe weight loss... im talking 30 pounds. 4 dress sizes... and all ive been doing is being lazy, barely getting out, not excercizing and gorging on food all day. ive never lost weight like this... aswell im getting severe fatigue basically every waking minute... i feel so drained... no energy.. and nothing i do seems to help my energy level. I get sore muscles... just from simple things as cleaning... or holding a baby... i feel like ive come back from the gym after a few days of intense work out. my biggest concern is my nails... they are very pale.. almost white... with faint horizontal stripe undernieth my nail beds of some of my nails... aswell as all my nails have beau's lines across them.. horizontal indents... on every single nail... my toe nails.. the same.. but the beau's lines are extremely worse on them. My Doctor has sent me for every blood work he can think of.. everything is fine.. my kidneys and thyroid are functioning properly.. i do not have diabetes... by blood cell count is proper... i am not malnurished.. my blood is completely normal. what can cause my nails to do this? everywhere ive read about beau's lines states is can be from severe illness, systamatic diseases ect... my doctor is not sure what to look for since my blood work is fine.. very reassuring... any suggestions? oh aswell as ive noticed when i get cuts... they take a while to heal... i got a small sore on my foot from rubbing against my shoe.. its been over a month... and it still hasnt fully healed... im not having bruising issues though..
