Somerset Woman Battling Severe Allergies Finds Lifeline in Her Dog

Kate Hegan, a 22-year-old teaching student from Somerset, faces a frightening reality: her body develops new allergies almost constantly, limiting her diet to just 25 safe foods. Each day carries the fear that a severe allergic reaction could become fatal. Diagnosed with mast cell activation syndrome (MCAS) just before her 18th birthday, Kate’s symptoms include facial flushing, gastrointestinal distress, brain fog, rashes, and even life-threatening anaphylaxis.

Managing MCAS requires Kate to take 15 medications daily and spend £1,000 a month on antibody injections not covered by the NHS. But her greatest support comes from her four-year-old black Labrador, Kenny, trained by the Medical Detection Dogs charity to alert her to imminent allergic reactions. When a reaction approaches, Kenny’s restlessness and focused attention give Kate a critical 10-minute warning, allowing her to prepare and seek help.

Kenny’s support has been life-changing. Kate was originally matched with the dog to manage a range of complex health issues, including postural tachycardia syndrome (PoTS), which causes frequent fainting episodes and severely impacted her quality of life during her teenage years. Before Kenny’s help, Kate faced daily hospitalizations and physical injuries, often feeling trapped by her conditions.

Thanks to Kenny’s alerts, Kate has regained independence and is now on the verge of graduating as a primary school teacher. “If it weren’t for Kenny, I wouldn’t be here,” she says. Her dog has not only saved her life but restored her hope and given her a future to look forward to.
