8. Sinus Infection and the Common Cold

Sinus Congestion

Sinus infections are painful and can cause inflammation of your nasal cavities and mucosa. As the lining of your nasal passages becomes irritated, it can bleed. Treatment of the underlying infection and keeping the nasal lining moist with a humidifier, antibiotic ointment, or saline spray will restore your nasal passages to good health. The congestion and runny nose associated with the common cold can lead to excessive nose blowing, which irritates and damages nasal membranes. To decrease trauma to your nasal passages, cover your nose with a tissue and gently blow through both sides at the same time rather than clearing one nostril at a time.

7. Allergies

Allergies

Allergies can be miserable, as they can cause itchy and watery eyes, asthma, fatigue, and nasal congestion. Outdoor allergens such as ragweed, tree pollens, and molds, and indoor allergens such as dust mites or pet dander, can trigger an immune response. Nasal congestion leads to sore, swollen nasal membranes and the production of mucus. Irritated nasal passages and constant nose blowing can cause the blood vessels in your nose to break, leading to nosebleeds. Avoid allergens when possible and treat symptoms when they arise. If you are prone to nosebleeds, blow your nose gently when needed.

6. Medications

medications

There are many prescription and nonprescription medications that can lead to nosebleeds. Anticoagulants such as aspirin, ibuprofen, heparin, and warfarin thin the blood and can cause bleeding. If you take blood thinners, avoid alcohol and cranberries, which can increase the effects of blood thinners. Over-the-counter drugs such as antihistamines dry out the nasal passages, which can cause irritation and bleeding. Nasal steroid sprays used to treat allergies can themselves be irritating to the nasal linings and cause nosebleeds.
