Reactions to stings can intensify: specialist explains when serious danger looms

Insect stings can trigger a range of reactions, from localized inflammation to severe allergic responses, according to allergy specialists. While a typical inflammatory reaction involves redness, swelling, and itching at the sting site, certain individuals, particularly young children with atopic dermatitis, may experience more pronounced and prolonged swelling. This is often an immune system response to proteins in the insect's saliva, not necessarily an allergy, and can be managed with disinfection, cooling, and antihistamine creams.

Small children, especially those with atopic dermatitis, may react more strongly to stings; redness and swelling may persist longer at the sting site. Such a reaction is not allergic; it is determined by an active immune system response to proteins in the saliva. Therefore, in such cases, it is sufficient to disinfect, cool, and apply an antihistamine ointment to the sting site.

True allergies to insect venom typically develop after multiple exposures. Key indicators of an allergic reaction include swelling extending beyond 10-15 cm, pain, and redness lasting over 48 hours. More severe systemic symptoms, such as skin rashes away from the sting site, swelling of the lips or eyelids, breathing difficulties, dizziness, or abdominal pain, signal a life-threatening situation. Specialists report seeing patients with severe reactions after multiple stings from bees or wasps, emphasizing the importance of seeking medical advice after any suspected allergic response.

This year we have already received patients who have repeatedly experienced severe allergic reactions after bee or wasp stings. However, only after several and increasingly severe episodes did these people finally decide to seek medical attention. I want to encourage everyone who suspects a possible allergic reaction to insects to consult a doctor and clarify the true cause of the past reaction. Then it will be calmer and clearer how to act, treat, and provide first aid.

Doctors advise immediate care for stings, including cooling and applying topical creams. However, if symptoms persist for more than three days, worsen, or spread, medical consultation is crucial. Infections can also complicate stings, leading to prolonged redness, swelling, warmth, and even fever, requiring specific treatment. Given that reactions can intensify with each subsequent sting, consulting an allergist is recommended for anyone with a history of concerning reactions to insect bites to understand the cause and appropriate management strategies.

If such measures do not help and symptoms persist for more than 3 days or the intensity of symptoms increases: the affected skin area expands, symptoms characteristic of an allergic reaction appear – it is necessary to consult a doctor. Also, insect stings quite often become complicated and an infection arises – then prolonged and expanding redness, swelling, oozing, and a feeling of heat are observed. Fever, enlargement of nearby lymph nodes are even possible. Then infection treatment is needed, which is also prescribed by a doctor.
