Can I develop a crested wheatgrass allergy later in life, or is it only present from childhood?

Allergies, including one to crested wheatgrass, can develop at any stage of life, not just in childhood. The body's immune system may begin to react to substances it was previously fine with. This is due to the immune system identifying these substances as harmful, even though they're not, and generating an allergic response.

The exact cause of why some individuals develop allergies while others don't isn't clearly understood. It may be a combination of genetic and environmental factors or due to changes in your living conditions, diet, immune system condition and overall health.

If you notice symptoms such as sneezing, itchy eyes, skin rashes, or difficulty breathing after exposure to crested wheatgrass, it's possible you've developed an allergy. An allergist can perform tests to confirm this and prescribe appropriate treatment, such as antihistamines, corticosteroids or allergy shots, to manage the symptoms.

Remember, even though allergies are generally not curable, they are manageable. If you suspect you have a new allergy, do not hesitate to contact a healthcare provider. Prevention is key, so if confirmed, avoid exposure to crested wheatgrass and take the prescribed medicine to control and ease your symptoms.
