Apart from the liver related Obstetric Cholestasis there are 2 other pregnancy related rashes which you may have. either PUPPS which is a rash with no blisters that is fairly common but there is also a more serious auto-immune disease brought on by pregnancy called Pemphigoid Gestationis. this is extremely unpleasant as well as being very, very rare so part of the problem is in getting diagnosed. your body becomes painfully itchy and you develop blisters on any part of your body. the treatment is oral steroids which work fast and effectively for most people. i developed this disease in my first pregnancy and am part of a support group which has about 30 members so far. if you think you may have this disease i would be very interested to hear from you as we are trying to raise awareness and encourage research into this horrible disease. my email address is [email protected]
