Angioedema

Symptoms

• Swelling: Swelling of the skin, usually on the lips, face, tongue, throat, hands, feet, or genitals.
• Itching: The affected areas may itch or tingle.
• Pain: Angioedema may sometimes cause pain or a burning sensation.
• Skin changes: The skin may appear pale or pink, depending on the severity of the swelling.
• Breathing problems: If the swelling occurs in the throat or tongue, it can lead to breathing difficulties, wheezing, or chest tightness.
• Digestive problems: In rare cases, angioedema can be accompanied by abdominal pain, nausea, or vomiting.

Causes

• Allergies: Reactions to food, medications, insect bites, pollen, or other allergens can cause angioedema.
• Medications: Some drugs, such as ACE inhibitors (used to treat high blood pressure), can cause angioedema as a side effect.
• Heredity: Angioedema can be caused by genetic factors and can be passed down from parents to children.
• Infections: Certain viral or bacterial infections can cause angioedema.
• Excessive stress: Severe emotional stress can cause angioedema in some people.
• Excessive exposure to heat or cold: Exposure to extreme temperatures can cause angioedema in sensitive individuals.

Diagnosis

If you experience symptoms of angioedema, it’s important to consult a doctor. The doctor will review your medical history and perform a physical examination. Additional tests may be done to identify the cause of angioedema, such as blood tests, allergy tests, or a skin biopsy. Keeping a diary of your symptoms, including possible triggers, can be helpful in making the diagnosis.

Treatment

Treatment of angioedema may vary depending on the cause, severity of symptoms, and frequency of attacks. Some possible treatment options include:

• Antihistamines: These medications can be prescribed to reduce allergic reactions and relieve symptoms of angioedema.
• Epinephrine injections: In severe cases of angioedema, especially those involving breathing problems, an epinephrine injection may be necessary to quickly reduce the swelling.
• Corticosteroids: These medications can be prescribed to reduce inflammation during an angioedema attack.
• Avoiding triggers: Identifying and avoiding triggers that cause angioedema attacks can help prevent symptoms.

It’s important to work with your doctor to determine the right treatment options for you.

Self-Care Tips

While angioedema may not be completely preventable, there are some measures you can take to reduce or manage attacks:

• Identify triggers: Try to identify the factors that may cause angioedema attacks in you and avoid them if possible.
• Wear a medical alert bracelet: If you have a known case of angioedema, wear a medical alert bracelet or pendant so that responders are aware of your condition in an emergency.
• Keep medications on hand: If you use antihistamines or other prescribed medications, ensure you always have them on hand for emergencies.
• Be cautious with new medications: If you need to use new medications, discuss your angioedema with your doctor to ensure they are safe for you.
