Not always. Some children outgrow certain allergies, while others may require long-term management. Regular follow-up helps track progress and response to treatment.
While most allergies can’t be “cured,” many can be effectively managed or even desensitized through immunotherapy, environmental control, and long-term care.
OIT is a treatment method where small, increasing doses of an allergen (like peanut or milk) are given to desensitize the child. Dr. Sowmya is one of the few experts in India offering this advanced therapy.
A skin prick test is a safe, painless diagnostic tool to identify specific allergens like dust, pollen, or food items. It’s commonly used in children by trained specialists like Dr. Sowmya.
Recurring sneezing, runny nose, skin rashes, wheezing, or tummy troubles could indicate an allergy. Early diagnosis helps prevent long-term complications.
A healthy diet, adequate sleep, outdoor play, and updated vaccinations are key. Dr. Sowmya offers personalized immunity-boosting plans rooted in scientific evidence.
Yes, up to 6–8 mild infections a year are normal in young kids. If symptoms are persistent or severe, Dr. Sowmya evaluates for underlying allergies or asthma.
Food allergies involve the immune system and can cause reactions like hives, vomiting, or breathing issues. Dr. Sowmya uses allergy testing to identify and differentiate food allergies from intolerances.
India follows the National Immunization Schedule (NIS), starting from birth to adolescence. Dr. Sowmya provides a customized, easy-to-follow immunization plan for every child.
