Background: Chronic urticaria is a common dermatosis with multifactorial etiology, including food intake. The incidence of chronic urticaria has doubled over the past decade. Chewing betel nut is common in Pakistan. Aim: To identify the association of betel nut with chronic urticaria as the underlying cause of the local population. Patients and methods: During one year, patients with chronic urticaria were examined in our department to determine the cause. The study was held in the Dermatology department of Jinnah Hospital, Lahore for one-year duration from June 2019 to June 2020. Results: Out of 2,625 all cases of urticaria, 943 (35.9%) were found to simply chew betel nut (supari) and pan (betel leaf) and gutta (betel and lime leaf). Ninety-two out of 95 volunteers improved symptoms after abstinence from betel nut. Eighty-five of them reported a recurrence of a retry with the suspected substance, confirming a causal relationship Conclusion: Observations suggest that consumption of betel in the form of sweetened supari and pan masala and gutka correlates with chronic urticaria. Key words: chronic urticaria, betel.
