The medical profession have no answers. I have suffered from idiopathic angioedema for 25 years, undertaken every allergy test and not found the cause. I have been taking 2 prescribed antihistimines Loratadine & Telfast every day which has helped to reduce the attacks to 2-3 per month. By sheer luck & perserverence I think I have found my solution, I started taking Sertraline 50 mg/day in November 2011 and have only had 1 attack in 10 months. The sertraline has reduced my stress and I guess the angioedema. Hope this helps any other desperate & frustrated sufferer.
Hello,
Unexplained swelling of the lip without any predisposing disease is frequently caused by allergies.An allergic reaction can occur suddenly, even in a person with no previous history of allergy.This swelling of the lip is called angioedema.It is the rapid swelling (edema) of the dermis, subcutaneous tissue, mucosa and submucosal tissues.Symptoms include swelling of any body part which appears suddenly and comes and goes.
Diagnosis is by clinical examination and complete blood tests,electrolytes and renal function tests.Traetment is by antihistaminics and steroids.
Other possibilities of swelling of lips may be acromegaly,Crohn’s disease,cardiac or renal disorders,herpes and myxedema.It is very difficult to make a diagnosis without examination.So pls get yourself examined by a physician and the diagnosis confirmed.Also sometimes angioedema can be life threatening when it involves the larynx and airways.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional queries.
