Some individuals in their 80s may develop food allergies, a phenomenon less frequent than childhood allergies but potentially more dangerous. Experts warn that those who develop food intolerances later in life face a heightened risk of severe reactions.
"Research indicates that while most food allergies are diagnosed in childhood, approximately 10 to 20 percent of people with food allergies are diagnosed as adults," explained Dr. Priyanka Porwal, Specialist Internal Medicine at Aster Clinic, Sheikh Zayed Road. "The incidence of adult-onset food allergies is increasing, though specific numbers fluctuate by region and demographic." She noted that a study revealed 15 percent of patients with a first-time food allergy diagnosis developed the condition as adults, with the highest incidence around the early 30s, though cases as late as age 86 have been reported.
Zaheer Hashim, a 35-year-old expatriate, experienced a severe allergic reaction to seafood he had previously consumed without issue. After eating mussels, he felt unwell and was treated at a clinic before being rushed to the emergency room. He was admitted to Rashid Hospital, where his face and tongue swelled dramatically, and his oxygen levels plummeted. He has since avoided seafood.
Dr. Alaa Zedan, Specialist Internal Medicine at Burjeel Hospital for Advanced Surgery in Dubai, highlighted the difficulty in identifying the exact causes of such allergies. "The immune system evolves over time," he stated. "Potential triggers include new allergen exposures, family history, immune system alterations, and limited childhood allergen exposure." Dr. Priyanka also mentioned that abrupt dietary changes could contribute, especially those related to weight loss or protein supplementation combined with new exercise routines.
Megha Phillip, a 32-year-old nurse, developed a wheat allergy after moving to Dubai. She experienced a severe reaction to flatbread, resulting in a fainting episode and a subsequent two-day stay in the ICU due to low blood pressure. She had regularly consumed similar foods without issue in New Delhi.
Dr. Alaa emphasized the importance of managing allergies, noting that while they typically do not pose life-threatening risks, individuals at risk of anaphylaxis should carry an epinephrine auto-injector for immediate use in case of symptoms.
