Introduction
In general, allergic symptoms may be caused by exposure to external allergens, a compromised skin barrier, allergic rhinitis, atopic dermatitis, allergic asthma, or other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve the condition through general care, medication, and other methods under a doctor's guidance. In daily life, maintain a light diet and avoid allergenic foods such as seafood and mangoes.
Generally, allergic symptoms may occur due to exposure to external allergens, a weakened skin barrier, allergic rhinitis, allergic dermatitis, or allergic asthma. It is recommended to seek medical attention promptly, identify the underlying cause, and follow a doctor's guidance for improvement through general care, medication, and other treatments. Specific analyses are as follows:
1. Exposure to external allergens: Contact with allergens such as pollen, dust mites, or animal dander can trigger an immune response in the body, leading to symptoms like itchy skin and sneezing. Immediately avoid known allergens, regularly clean your living environment, use a mite-removal device to eliminate dust mites, and wear a mask when going outdoors to reduce exposure to allergens.
2. Weakened skin barrier: Thin stratum corneum and poor moisture retention make the skin prone to irritation and allergic reactions, manifesting as redness and dryness. Use gentle moisturizing creams daily—such as ceramide-based lotions—and avoid frequent use of irritating facial cleansers. Apply sun protection when outdoors to strengthen the skin’s barrier function.
3. Allergic rhinitis: Inflammation of nasal mucosa occurs after exposure to allergens, causing symptoms such as nasal congestion, runny nose, and sneezing. Patients should follow medical advice to use medications such as mometasone furoate nasal spray, loratadine syrup, or cetirizine hydrochloride tablets.
4. Allergic dermatitis: Skin inflammation occurs after contact with allergens or irritants, presenting as rashes, itching, and swelling. Avoid scratching affected areas and follow medical instructions to apply topical treatments such as desonide cream or hydrocortisone butyrate cream, or take oral medications like ebastine tablets to relieve symptoms.
5. Allergic asthma: Allergens trigger airway spasms, resulting in wheezing, chest tightness, and coughing; severe cases may impair breathing. Patients should immediately leave the allergenic environment and follow medical guidance to use medications such as budesonide/formoterol powder inhaler, salbutamol aerosol, or montelukast sodium tablets.
In daily life, maintain a light diet and avoid easily allergenic foods such as seafood and mangoes. Keep a regular sleep schedule to enhance immunity. Record episodes of allergic reactions to identify specific allergens and avoid them long-term. Comprehensive care can help reduce the frequency of allergic episodes and support overall health.
