What triggers grass allergy?

Are you at risk of grass allergy?

• Experience sneezing, a runny nose, itchy eyes, or congestion in the presence of freshly cut grass. 
• Have a history of asthma or allergies in your family. 
• Notice your symptoms worsen in the spring or summer when grasses release their pollen. 
• Feeling skin irritation or rashes upon contact with grass. 

When should I consult a doctor?

Is there testing for grass allergy?

• Skin prick test (SPT): A small quantity of grass pollen extract is applied to your skin, usually on the forearm or back, and then lightly pricked. A small, itchy, red bump will appear within 15–20 minutes if you are allergic. 
•  Blood test (specific IgE test): This test measures the amount of IgE antibodies in your blood in response to grass pollen. It is beneficial if you have skin conditions or are on medications that could interfere with skin testing. 

How is grass allergy treated?

•  Medications: Over-the-counter antihistamines help alleviate sneezing and itching. Nasal sprays help reduce congestion. Decongestants may offer temporary relief. 
• Avoidance strategies: Limit outdoor activities during high pollen seasons, keep windows closed, utilise air purifiers, and shower after being outside. Wearing sunglasses and masks can help lessen pollen exposure. 
• Immunotherapy: Allergy shots or sublingual tablets gradually desensitise the immune system to grass pollen, providing long-term relief.

Can grass allergy be prevented?

• Minimise outdoor activities: Refrain from venturing outside during peak pollen times, especially on windy days. Staying indoors lessens exposure to airborne grass pollen. 
• Keep windows and doors shut: Bar pollen from entering your home by keeping doors and windows closed. Utilise air conditioning with clean filters to help maintain indoor air quality. 
• Use air purifiers and HEPA filters: These devices trap pollen and other airborne particles. A cleaner indoor environment can alleviate allergy symptoms. 
• Wear sunglasses and masks: Sunglasses shield your eyes from pollen, while masks help limit inhalation. This reduces direct contact with allergens. 
• Shower and change attire: Rinse off pollen after being outdoors to avoid transferring it indoors. This helps lessen prolonged exposure and irritation. 
• Take antihistamines or nasal sprays: if recommended, begin taking medication before allergy season. Preventative treatment can aid in effectively managing symptoms. 

What foods should I avoid with a grass pollen allergy?

1. Wheat, barley, rye, and oats: These grains share a connection with grass and can aggravate symptoms. Consider gluten-free substitutes if needed. 
2. Tomatoes: Individuals with grass allergies may have reactions to tomatoes due to cross-reactivity with proteins found in grass pollen. Cooking them may alleviate symptoms. 
3. Peaches and melons (such as watermelon, cantaloupe, and honeydew): These fruits contain proteins comparable to grass pollen and may lead to itching or swelling in the mouth. 
4. Oranges and other citrus fruits: Certain individuals allergic to grass report mild reactions to citrus fruits like oranges, lemons, and limes. 
5. Celery and carrots: These vegetables can provoke OAS in those allergic to grass pollen. Cooking them might make them more tolerable. 
6. Peanuts: Occasionally, individuals with grass pollen allergies may also react to peanuts due to the similarities in proteins.
