Early this morning, a few minutes after eating a peach, I seemed to have difficulty breathing. I inspected my throat and noticed mild swelling of the tongue, lips, and uvula and inflammation on my palette and the back of my throat. My throat was also very itchy. As my circumstance did not seem life threatening, I decided to try to analyze my condition on my own. I have never exhibited an allergic reaction to peaches or any fruits.
After a quick and motivated search, I concluded my response seems to be
oral allergy syndrome. I brushed my teeth to remove any lingering peach from my mouth, though that can't mitigate ingestion. I have considered inducing vomiting, but the description of OAS suggests the symptoms may be confined to my mouth and throat, and vomiting might worsen the reaction.
At peach +30 minutes, the irritation seems to be confined to my mouth and upper digestive tract, though my breathing is somewhat labored. My condition is not worsening. I will drink water and fluids to try to decrease the concentration of allergen.
Peach +1:30, the irritation is gradually subsiding. I have eaten a tortilla and drunk about 1.5 L of water.
I have another peach, so if my condition stabilizes, I may try to reproduce the reaction during the day with a small amount of peach when there are people around should I react more strongly. The novelty of this situation did not overcome my significant discomfort.
