Allergy Symptoms Checker – Swelling Of Tongue, Face and Other Body Parts

Swelling And Angioedema Explained

Swelling of the tongue, face or other parts of the body – also called angioedema, which refers to swelling beneath the skin’s surface layer or below the mucous membranes.  It is caused by blood leaking out of small blood vessels such as veins, deep within the tissues of the body [1]. Swelling closer to the skin’s surface is known as hives, and this often accompanies angioedema if an allergic reaction to food is the cause.  


In What Parts Of The Body Swelling Can Occur

Angioedema is usually marked by deep swelling around the lips and eyes [2], but is sometimes seen in the hands, feet and genitals.  In very rare situations angioedema can occur in the throat, tongue or lungs, causing breathing difficulties. It can also occur in the stomach or bowels, which, in turn, can trigger stomach or chest pains [1].  However, this is also very rare. With appropriate treatment, angioedema usually resolves in under 24 hours [2]. It does not cause permanent damage to internal organs, although it can be uncomfortable and distressing, particularly if it is associated with breathing difficulties.
