Swollen lips?


Hello Doctor, I would like to ask about my mother's lips.
They suddenly became very red for an unknown reason, but after a few days, the redness gradually diminished.
However, her lips are now peeling and are somewhat painful.
Could you please explain what might be causing this? Thank you, Doctor.

Hello: It is against regulations to diagnose diseases online, so I apologize, but please do not use the internet as a substitute for an actual medical consultation, as the potential misdiagnosis rate is very high.
If you have gradually improved, I recommend applying some petroleum jelly to protect your lips.
However, if the issue continues to be bothersome, please seek medical attention in person.
Wishing you safety.

More Info


Sudden lip redness and peeling can be concerning, especially when accompanied by discomfort. There are several potential causes for these symptoms, and understanding them can help in determining the appropriate course of action.

One common cause of sudden lip redness is contact dermatitis, which can occur when the lips come into contact with an irritant or allergen. This could include certain foods, cosmetics, dental products, or even environmental factors like extreme weather conditions. If your mother recently changed any lip products or has been exposed to new foods, this could be a possible explanation.

Another potential cause is cheilitis, which is inflammation of the lips. This condition can be caused by a variety of factors, including dehydration, vitamin deficiencies (especially B vitamins), or fungal infections. If your mother has been experiencing dry weather or has not been drinking enough water, this could lead to dryness and subsequent peeling.

Additionally, conditions like angular cheilitis, which is characterized by cracks at the corners of the mouth, can also cause redness and discomfort. This condition is often associated with fungal or bacterial infections and can be exacerbated by factors such as saliva accumulation or nutritional deficiencies.

In some cases, sudden lip redness can be a sign of an allergic reaction, particularly if it is accompanied by swelling, itching, or hives. If your mother has recently started any new medications or has been exposed to new substances, this could be a factor to consider.

To address the symptoms, it is essential to first identify the underlying cause. Here are some general recommendations:
1. Avoid Irritants: If you suspect that a specific product or food may have triggered the reaction, it is best to avoid it. This includes any new lip balms, cosmetics, or foods that were recently introduced.

2. Moisturize: Keeping the lips well-moisturized can help alleviate dryness and peeling. Look for lip balms that contain soothing ingredients like beeswax, shea butter, or coconut oil. Avoid products with fragrances or alcohol, as these can further irritate the lips.

3. Hydration: Ensure that your mother is drinking enough water throughout the day. Dehydration can exacerbate dryness and peeling.

4. Nutritional Support: If there is a concern about vitamin deficiencies, consider incorporating a balanced diet rich in fruits, vegetables, and whole grains. If necessary, a healthcare provider may recommend supplements.

5. Topical Treatments: If the redness and peeling persist, over-the-counter hydrocortisone cream may help reduce inflammation. However, it is essential to use this sparingly and not for extended periods without consulting a healthcare professional.

6. Consult a Healthcare Provider: If the symptoms do not improve or worsen, it is crucial to seek medical advice. A healthcare provider can perform a thorough examination, possibly conduct allergy testing, and recommend appropriate treatments based on the diagnosis.

In conclusion, sudden lip redness and peeling can result from various factors, including irritants, allergies, or underlying health conditions. By identifying the cause and taking appropriate measures, it is possible to alleviate the symptoms and promote healing. If there are any concerns or if the condition persists, consulting a healthcare professional is always the best course of action.
