Hypersensitivity Reactions to Insulin

Hypersensitivity reactions to insulin occur when the body’s immune system mistakenly identifies insulin as a harmful substance. This can lead to allergic reactions, which may include skin rashes, swelling, or even severe reactions like anaphylaxis. Such reactions are relatively rare but can occur with different forms of insulin. Factors like the origin of the insulin (human or animal) and the presence of additives can influence these responses. It's important for individuals with diabetes to monitor their reactions and consult healthcare providers if they experience adverse symptoms after insulin administration.
