angioedema (redirected from Angioneurotic oedema)

angioedema /an·gio·ede·ma/ (-ĕ-de´mah) a vascular reaction involving the deep dermis or subcutaneous or submucosal tissues, representing localized edema caused by dilatation and increased permeability of the capillaries, and characterized by the development of giant wheals.

hereditary angioedema  an autosomal dominant disorder of C1 inhibitor (C1 INH), which causes uncontrolled activation of the classical complement pathway, manifested as recurrent episodes of edema of the skin and upper respiratory and gastrointestinal tracts with increased levels of several vasoactive mediators of anaphylaxis. It may be mediated by such factors as minor trauma, sudden changes in environmental temperature, and sudden emotional stress.

angioedema

[an′jē·ō′idē′mə]

a dermal, subcutaneous, or submucosal swelling that is acute, painless, and of short duration. It may involve the face, neck, lips, larynx, hands, feet, genitalia, or viscera. Angioedema may be hereditary or the result of a food or drug allergy, an infection, emotional stress, or a reaction to blood products. Treatment depends on the cause. Severe angioedema may require subcutaneous injections of epINEPHrine, intubation, or tracheotomy to prevent respiratory obstruction. Prevention depends on the identification and avoidance of causative factors. Also called angioneurotic edema. See also anaphylaxis, serum sickness, urticaria.

Patient discussion about angioedema.

Q. What can cause an angioedema on 15 year old girl? I’ve been getting angioedema signs on my left arm for the past few weeks, not severe but it itches and sure don’t help my low-as-it-is self esteem…

A. The following may cause angioedema -

Animal dander
Certain medications (drug allergy)
Emotional stress
Exposure to water, sunlight, cold or heat
Foods (such as berries, shellfish, nuts, eggs, milk, other)
Insect bites
Pollen

Hives or angioedema may also occur after an illness or infection.
Try to see if you were exposed to any of this and report it to your Dr.

Q. Is severe diarrhea sign of angioedema? I have sudden onset of painful diarrhea with stomach pain.

A. Severe diarrhea can be a sign of angioedema but it is a very unlikely way of angioedema to show, especially if that is the only symptoms and there is no obvious seen swelling of skin or shortness of breath. Stomach ache with diarrhea is usually caused by an infection, most likely a viral infection, and should pass within a few days. If symptoms are unbarable or continue, you should see your doctor.
