Why is it that when you eat watermelon your throat feels swollen?

Experiencing a swollen throat after eating watermelon may be linked to an allergic reaction or sensitivity to certain proteins found in the fruit. Watermelon contains compounds that can trigger oral allergy syndrome, especially in individuals allergic to ragweed or certain fruits. Additionally, if the watermelon is cold or consumed quickly, it might cause a temporary sensation of swelling due to temperature or irritation. If this sensation persists, it's advisable to consult a healthcare professional.
