Heartburn: Onions can relax the lower esophageal sphincter, potentially leading to heartburn in susceptible individuals.
Allergic Reactions: In rare cases, individuals may be allergic to onions, leading to symptoms like itching, swelling, and difficulty breathing. Allergic reactions are more common with raw onions.
