How does exposure to other allergens affect the severity of a crested wheatgrass allergy?

The severity of crested wheatgrass allergy can potentially be influenced by exposure to other allergens. This is due to a phenomenon known as the "allergic load" or "total load". The allergic load concept proposes that the human body can tolerate a certain amount of allergens without showing symptoms, but once this threshold is crossed, allergic reactions can occur or worsen. Therefore, if a person with a crested wheatgrass allergy is also exposed to other allergens, their immune system might be overburdened, leading to a more severe reaction to the crested wheatgrass.

Moreover, there is also the potential for cross-reactivity. Cross-reactivity occurs when the proteins in one substance are similar to those in another, causing the immune system to react to both. For instance, a person allergic to grass pollen may also respond to certain fruits, vegetables or grains because they contain similar allergenic proteins. If cross-reactive allergens are present along with crested wheatgrass, the severity of response might increase.

However, it's critical to individualize this information. The intensity of allergic reactions can vary greatly among individuals, largely due to genetic factors and the level of repeated exposure to the allergens. Some people may have a stronger immune response, leading to more severe symptoms, while others may have milder reactions.

In cases where triggering a severe reaction is a concern, allergy tests could be very beneficial. Skin-prick tests, blood tests, or elimination diets can help in identifying additional allergens. Consultation with an allergist is recommended for personalized advice. It's also crucial to note that various allergy pills and treatments can help manage the symptoms of multiple allergies effectively. Such treatments help by reducing the immune system's response, thereby reducing the allergy symptoms.
