What role does Insulin play in Allergie?

Insulin is primarily a blood sugar-regulating hormone, but it also has immunomodulatory effects. It can influence histamine release from mast cells and modulate IgE production. Some studies suggest a link between insulin resistance and increased allergy risk, particularly in asthma and atopic dermatitis. However, the evidence is mostly mechanistic and observational; there is no strong clinical proof for a direct causal role. Insulin is not typically covered in consumer DNA tests for allergies. Caveat: The clinical relevance is unclear, and lifestyle factors such as diet and exercise have a greater impact on allergies than insulin alone. If allergies are suspected, specific IgE tests or skin prick tests are necessary.
