Every night my entire body is very itchy and it very disturbing in my sleep. I have taken so much loratadine and antihiatamins buy it ddnt work out.?

Night Itch. Are you itching at all during the day? Is anyone else who shares your home itching as well? Do you have a rash?
Itching. A common cause of itching that is sometimes missed is gallbladder problems, leading to back-ups in the liver. Another is a thyroid problem. Not 100%, but worth checking out if you've tried everything else!
