When you come into contact with an allergen, the immune system sends out antibodies to attack what it believes to be a harmful foreign substance, even though it is benign.<\/p>\n\n\n\n
Nosebleeds can be common in people suffering from seasonal allergies. They usually occur as a result of damaged blood vessels in the nasal septum<\/a>. The two most common causes of allergy-induced nosebleeds are:<\/p>\n\n\n\n Let\u2019s examine each of these a little more closely.<\/p>\n\n\n\n If the nasal cavity becomes too dry, the blood vessels can become damaged, leading to nosebleeds. A dry nose can come from a lack of moisture in the air, dehydration, blowing your nose too frequently or certain medications.<\/p>\n\n\n\n Allergy medication, specifically antihistamines and corticosteroids, can dry out the nasal cavity and lead to nosebleeds.<\/p>\n\n\n\n Antihistamines work by blocking the effects of histamine in your body. Histamine is a substance released by your body when it comes into contact with an allergen. While effective at reducing symptoms, antihistamines<\/a> can dry out the nasal cavity and lead to nosebleeds. <\/p>\n\n\n\n Corticosteroid sprays reduce the nasal cavity’s swelling and mucus, relieving symptoms of congestion, runny nose and more. A study on the risk of epistaxis (nosebleeds) when using intranasal corticosteroid sprays found that patients treating allergies with intranasal corticosteroids were at an increased risk for nosebleeds<\/a>.<\/p>\n\n\n\n The humidity on a summer\u2019s day in Forest Park may help with some of the dryness, but there are additional steps you can take to increase the moisture in your nose, such as:<\/p>\n\n\n\n If your allergies are causing sneezing, congestion or a runny nose, you may blow your nose more than usual. The irritation from blowing your nose can damage the nasal cavity’s blood vessels.<\/p>\n\n\n\n Avoid blowing your nose too frequently, and keep it moisturized with a humidifier or nasal moisturizer spray.<\/p>\n\n\n\n Treating a nosebleed is fairly simple:<\/p>\n\n\n\n Because the nasal cavity and throat are connected, blood may collect in your mouth. Spit any blood into a bowl or sink and ensure not to swallow any.<\/p>\n\n\n\n If nosebleeds last more than 30 minutes, produce a greater amount of blood than usual, cause you to feel lightheaded or follow an injury, seek medical care immediately.<\/p>\n\n\n\n Contact Midwest ENT Centre today to speak to an ear, nose and throat specialist about your allergies or nosebleeds.<\/p>\n\n\n\n\n
