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.
Hereditary angioedema is caused by the lack of a protein in the blood called C1-esterase inhibitor. Unlike allergic angioedema, the swellings tend to come on slowly. It can affect the throat and the bowel, and cause abdominal (tummy) pain.
