Why Does My Lip Swell Up Due to Allergies?

Some people experience allergic reactions that manifest as swollen lips, which may also be accompanied by itching sensations. Swollen lips due to allergies can affect one's appearance and cause discomfort to the patient. It is crucial to promptly isolate the allergen and treat the condition according to medical advice. Daily, it is recommended to consume plenty of vegetables and fruits to supplement vitamin intake and avoid spicy and irritating foods.

There are numerous triggers that can lead to allergic lip swelling, but what are the main causes? Let's explore them below.

Allergic lip swelling is caused by angioedema triggered by allergies, which is often related to exposure to allergens. It can also be due to underlying health conditions that lead to allergic reactions. If the cause is contact with an allergen, patients can identify and avoid their specific allergen. However, it is crucial to follow medical advice for treatment before attempting to eliminate the allergen.

Allergic cheilitis is an inflammatory condition caused by contact of the lips or surrounding skin with certain irritants. Its etiology and pathogenesis are similar to contact dermatitis, making it an allergic disease. For instance, cosmetics like lipstick, spicy foods, and toothpaste can all trigger contact cheilitis. Actinic cheilitis is more common among farmers, fishermen, and outdoor workers in tropical regions, and it is associated with prolonged sun exposure. The severity of symptoms varies depending on the duration of sun exposure. Symptoms are typically more pronounced during summer, worsening with longer sun exposure and improving with reduced exposure. Both conditions share similar mechanisms, involving allergic inflammation of the lips. However, they differ in their symptoms, with contact cheilitis affecting the area of contact and actinic cheilitis causing less blistering but more prominent signs of inflammation like redness or bleeding.

Here are some prevention methods:

• Eliminate bad habits like licking or biting your lips, and minimize smoking and drinking.
• Consume plenty of fresh vegetables such as bean sprouts, rape, cabbage, and white radish to increase vitamin B intake.
• Minimize sun exposure and stay hydrated. Adequate water intake helps maintain bodily functions and effectively prevents dry and cracked lips.
• Both men and women should use lip balm, preferably one with minimal irritating ingredients and no color. For those with allergic tendencies, applying sesame oil or honey to the lips with a cotton swab can also provide excellent moisture retention.
• Use a humidifier to increase air humidity. Placing a humidifier indoors creates a comfortable environment, especially during daylight hours, which significantly reduces the drying effects of indoor air and the risk of developing cheilitis.
