What effect can an allergic immune response have on the body?

An allergic immune response can indeed cause additional tissue damage in the body. This reaction occurs when the immune system overreacts to a substance that is typically harmless, known as an allergen. During an allergic reaction, the immune system produces antibodies such as Immunoglobulin E (IgE) in response to the allergen. This leads to the release of histamines and other chemicals, which can result in inflammation and damage to surrounding tissues. This process may manifest in various forms, such as skin rashes, respiratory issues, and gastrointestinal symptoms, depending on the individual and the type of allergen involved.

The other choices do not accurately reflect the nature of allergic responses. While an allergic reaction indicates that the immune system is active, it does not enhance overall immune function or protect against all diseases, which is a misconception of immunity. Furthermore, allergic responses do not ensure full recovery without treatment; in fact, they often require intervention, such as antihistamines or corticosteroids, to alleviate symptoms and minimize tissue damage.
