Seasonal allergies, also commonly referred to as hay fever or allergic rhinitis, is an allergy to weeds that pollinate. The damaging immune response that occurs consists of inflammation of the nose and airways. Allergic rhinitis afflicts people of all ages including nearly 10% of U.S. citizens and 30% of the population worldwide.
Epistaxis, a condition commonly referred to as nosebleeds, occurs at the vascular area within the nose, which can bleed profusely as a result of facial trauma. The nose’s arterioles (tiny blood vessels) are vulnerably positioned and thus can easily rupture.
Approximately 60 percent of people experience epistaxis at some point in their life. Only 6 percent of those who suffer with nosebleeds tend to seek medical treatment, and even fewer require hospitalization.
Though epistaxis can occur at any age, it mostly has a bimodal distribution, afflicting toddlers to children age 10, as well as adults over 50. There are two types of nosebleeds – those that stem from the front of the nose (anterior) which are most common, and those that stem from the back of the nose (posterior) which are less common and more severe in nature.
