According to the American Academy of Allergy Asthma and Immunology (AAAAI), angioedema is the swelling in the deep layers of the skin, often seen with hives. It most often occurs in soft tissues such as the eyelids, mouth, or genitals. Angioedema may involve swelling in the face, airways, and throat. The swelling can begin within minutes or develop over the course of hours. Because of the rapid progression of this condition, it can lead to potential airway obstruction and suffocation. Angioedema happens when there is a reaction to a drug or other substance like an allergen–which acts as a trigger.
There are many causes of angioedema but they all depend on the type of angioedema that you have. The 4 main types of angioedema are Allergic, idiopathic, drug-induced, and hereditary.
As mentioned earlier, angioedema can affect a person’s hands, face, feet, and even the genitals. However, there are other symptoms that you should look out for which include:
Severe angioedema can cause difficulty with breathing or swallowing. If this happens, emergency treatment is necessary. Most people who have severe reactions should always carry a syringe of self-injecting epinephrine to be used if a severe reaction occurs.
The doctor can diagnose angioedema by examining the affected skin or the appearance of the symptoms. They can also ask the patient for a description of what triggered the symptoms and by checking their family and medical history. Doctors may also check if the patient is taking any medications that have an angiotensin-converting enzyme (ACE) inhibitors.
The patient may take further tests to make sure or confirm the type of angioedema he or she has. These may include a skin prick test to confirm a link to possible allergies. A skin prick test is a blood test that confirms how the patient’s immune system reacts to an allergen.
Most cases of angioedema get better without treatment after a few days, but some people prefer to use medication. For mild angioedema, taking antihistamines relieves the itching and reduces the swelling. Corticosteroids that are taken orally may also be used if other treatments are ineffective. Serious side effects may be experienced if corticosteroids are taken for a long time. For idiopathic angioedema, a high dose of antihistamine may help. Hereditary angioedema cannot be cured, however, regular drug treatment and specialized medications can prevent and manage the symptoms. If you also had symptoms of anaphylaxis during an episode of angioedema, you will probably be given an adrenaline auto-injector pen in case your symptoms return.
