What Are the Mortality Rates for Angioedema?

Screening and Early Detection

This article will explain what you need to know about types of angioedema, who is at risk for it and why, and the importance of screening and early detection.

Angioedema is a swelling (edema) of the tissue layer located under the skin or mucous membrane. It most commonly affects soft tissues on the eyelids, mouth, orgenitalsbut can also affect the lungs, digestive tract, arms and legs, and throat.

Symptoms of Angioedema

How Common Is Angioedema?

The prevalence of angioedema varies depending on its cause.  Hereditary angioedema (HAE) is a rare type of angioedema. It affects an estimated 1 in 50,000 people in the United States.

Acquired angioedema or AAE is even less common. It is a nonallergic type that affects an estimated 1 in 100,000 to 1 in 500,000 people.

Allergic angioedema is the most common type of angioedema. It’s responsible for an estimated 1 million emergency department visits in the United States each year.

Black Americans have a higher rate of incidence than other U.S. populations for a type of angioedema calledangiotensin converting enzyme (ACE) inhibitorangioedema, or ACEI angioedema.

This type of angioedema is associated with certain medicines, including a commonly prescribed blood pressure drug class called angiotensin-converting enzyme inhibitors such as Lisinopril and some blood pressure medications. Research reveals that with tens of millions of people taking ACEIs, the incidence of ACEI angioedema is rising.

Significantly, half of all cases of angioedema occur in those aged 50, suggesting age plays a major role.

Gender differences play a well-documented role, too. It’s been said for decades that women with HAE experience worse symptoms and more attacks than men with HAE.

The Role of HormonesConditions such as taking birth control pills (oral contraceptives) and experiencing hormonal changes associated with pregnancy can also trigger angioedema attacks in women.

The Role of Hormones

Conditions such as taking birth control pills (oral contraceptives) and experiencing hormonal changes associated with pregnancy can also trigger angioedema attacks in women.

Causes of Angioedema and Risk Factors

Common causes of angioedema and associated risk factors for triggers include allergies and conditions listed below:

Causes and Treatment of Swollen Finger Joints

Typically, angioedema isn’t life-threatening. When it causes swelling in the throat and mouth, or when it’s associated withallergy-triggered anaphylactic shock, though, it can lead to suffocation and can be fatal. Immediate assessment of the airway is critical to ensure breathing is not compromised due to swelling. Over the same time period, while other angioedema-related diseases remained rare, nonhereditary angioedema deaths reportedly increased.

When to See a Healthcare ProviderAngioedema can quickly worsen. Symptoms of shortness of breath, dizziness, and airway blockage can come on suddenly. If you suspect that you or someone you know is experiencing allergic angioedema and is having difficulty breathing, call 911 immediately.

Treating angioedema in a medical emergency typically requires:

To determine the underlying cause of the angioedema attack, you may be offered lab tests including:

Symptoms of Anaphylaxis

Summary

A Word From Verywell

Knowing you have an allergy or genetic condition isn’t always obvious. If you suspect angioedema, though, talk to a healthcare provider about prevention and treatment options. In cases of angioedema in the throat or mouth, seek immediate medical attention.
