Tissue homeostasis can also depend on the maintenance of body functions like digestion, respiration, urination, and lymphatic control. The health of the skin is typically important, along with normal skeletal support, muscle movement, and responses between the nervous system and muscles.
Practice Essentials. Angioedema is the swelling of deep dermis, subcutaneous, or submucosal tissue due to vascular leakage.Acute episodes often involve the lip, eyes, and face (see the image below); however, angioedema may affect other parts of body, including respiratory and gastrointestinal (GI) mucosa.
Cases where angioedema progresses rapidly should be treated as a medical emergency, as airway obstruction and suffocation can occur. Epinephrine may be life-saving when the cause of angioedema is allergic. In the case of hereditary angioedema, treatment with epinephrine has not been shown to be helpful.
