In Angioedema, the deep layers of the skin and the tissue underneath swell suddenly and severely.

It is similar to hives and often occurs with urticaria (hives), but the swelling is more profound and lasts longer. It is not always itchy, either. Swelling can happen in the face, lips, tongue, throat, and hands.

Certain medications, allergic reactions, and underlying medical conditions can cause Angioedema.

At Juniper Allergy in San Antonio, we specialize in providing individualized medical care to both adults and children suffering from allergies.

Causes of Angioedema

Angioedema can arise due to various triggers, such as allergies, pre-existing medical conditions, or medications. Commonly observed causes of Angioedema include:

A reaction to allergens:

An allergic response to specific allergens, including food, drugs, or insect stings, may precipitate angioedemas.

The underlying medical conditions:

Hereditary Angioedema is a medical condition that can lead to the occurrence of Angioedema.


Certain medications, including ACE inhibitors, may be associated with Angioedema as a potential side effect.

Preventing Angioedema

Despite being unknown in origin, it is possible to reduce the risk of Angioedema by taking precautions. Taking the necessary steps can help in the prevention of Angioedema.

Identifying triggers

It is imperative to avoid foods, medications, and environmental factors that trigger your Angioedema.


Your doctor may prescribe medication to prevent Angioedema if you have a condition like hereditary.

Keep an eye out for symptoms

People with a history of Angioedema should be aware of their symptoms and seek medical attention if they occur.

Consult an allergist or immunologist

You should consult an allergist or immunologist to get a proper diagnosis and treatment plan.

The use of antihistamines

Antihistamines can help prevent Angioedema when allergic triggers occur.

It is imperative to be aware that prompt medical assistance is essential if one has extreme or grave symptoms, such as respiratory or ingestion difficulty.

Symptoms of Angioedema

Different parts of the body can experience other symptoms of Angioedema. The following are some of the most common symptoms:

  • Tightness of the throat
  • Difficulty breathing
  •  Pain in the affected areas

It is imperative to seek medical advice promptly if any of the symptoms of Angioedema are present. Without treatment, it can become life-threatening if it affects the throat or tongue.

Treatment and Diagnosis of Angioedema

At Juniper Allergy, diagnosis of Angioedema is through a combination of symptoms reported by the patient, physical examination, and possibly additional tests such as blood and skin tests to detect the root cause.

We will explore methods of mitigating the physical effects of the allergen. If that proves unsuccessful, we have a variety of treatments available, ranging from medication to immunotherapy (allergy shots).

Cluster Immunotherapy, tailored to the patient’s needs, is a more efficient alternative to conventional immunotherapy that helps develop a greater tolerance to specific allergens. Our physicians can provide this customized plan to those who pursue allergy shots.

Angioedema Facts

  • Hereditary Angioedema (HAE) is the most prevalent type of Angioedema and is a result of a genetic mutation that impairs the body’s aptitude to control certain blood clotting elements.
  • Angioedema can present itself in any body region, though it typically occurs on the face, lips, tongue, throat, and hands.
  • Medications such as antihistamines and corticosteroids can reduce inflammation and curtail the risk of further instances of Angioedema.
  • In exceptional circumstances, Angioedema can be highly hazardous if the swelling is in the throat or tongue, potentially leading to breathing complications.
  • Hereditary Angioedema is a relatively uncommon genetic condition, with an estimated prevalence of 1 in 10,000 to 1 in 50,000 people.
