How does the body's immune system react to Crested Wheatgrass pollen?

When exposed to Crested Wheatgrass pollen, your body's immune system perceives it as a foreign invader. Specifically, the immune system identifies the protein in the pollen as harmful, even though it isn't. It responds by producing substances called antibodies to attack the pollen, in this case known as allergen-specific IgE.

These antibodies trigger immune cells called mast cells, which reside in all body tissues, especially the nose, throat, lungs, skin, and gastrointestinal tract. When these mast cells come into contact with the pollen, they release a multitude of chemicals. One of these is histamine, a key player in the symptoms of an allergic reaction.

Histamine can cause inflammation and swelling of the nasal passages, itchiness, excessive mucus production, and sneezing - the typical symptoms of hay fever. It can also cause symptoms in the eyes like itching, redness, and watering. In some people, the allergic reaction to pollen can trigger asthma symptoms like coughing, wheezing, shortness of breath, and tightness in the chest.

Apart from these immediate symptoms, repeated exposure to pollen can lead to chronic inflammation and long-term damage to the nasal passages and lungs. Allergy pills, also known as antihistamines, work by blocking the action of histamine, thereby providing symptomatic relief. They don't cure the allergy but can greatly reduce the symptoms and improve quality of life for those affected. It is important to note that not all allergy pills work the same way for everyone, and some people may experience side effects, so consultation with a healthcare provider is advised.
