T78: Adverse effects, not elsewhere classified

T78.3: Angioneurotic oedema

Swelling of this type can be due to an allergy, for example. With an allergy, the immune system overreacts to certain substances. Such substances may be harmless substances in the environment, drugs or certain chemicals, for example. Swelling of this type can also be triggered in another way, by a drug or by an illness.

The swelling can affect the face. The eyelids, lips or cheeks can then swell up. If the tongue or larynx swell up, you can have problems swallowing. You may also be short of breath. Other parts of the body, such as the hands or genital organs, can also swell up. If the mucous membrane in the stomach or intestine swells up, you can suffer abdominal pain.
