What causes frequent nosebleeds?

Generally speaking, frequent nosebleeds may be caused by nasal trauma, excessive cleaning inside the nasal cavity, atrophic rhinitis, deviated nasal septum, hemophilia, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Nasal Trauma: When the nose suffers impact or pressure, blood vessels inside the nasal cavity may rupture and bleed, leading to recurrent nosebleeds before full recovery. During a nosebleed, gently press the nostril on the bleeding side, plug the nostril with clean tissue paper, and keep the head slightly forward. The symptom usually resolves gradually once the injury heals, so there is no need for excessive concern.

2. Excessive Nasal Cleaning: Using overly irritating nasal wash solutions or blowing the nose too forcefully may damage the nasal mucosa, causing bleeding. It is recommended to use mild nasal wash solutions, avoid forceful nose-blowing, and gently wipe the nose with tissues when necessary.

3. Atrophic Rhinitis: This condition may be related to deficiencies in essential nutrients or high levels of dust in the air. It can prevent nasal secretions from being discharged properly, leading to accumulation within the nasal cavity, which may result in bleeding. Symptoms may also include dry crusts and pain. Patients are advised to take medications such as Rhinitis Kang tablets, Xiangju capsules, or budesonide nasal spray under a doctor’s supervision to alleviate symptoms.

4. Deviated Nasal Septum: This may result from congenital malformations or untreated dislocations. The mucosa at the deviated portion of the nasal septum is typically thin, making blood vessels more exposed and prone to rupture upon irritation, leading to bleeding. Other symptoms may include nasal congestion and headaches. Patients should seek timely medical care; surgical correction (septoplasty) may be necessary in some cases.

5. Hemophilia: This may be caused by genetic inheritance or gene mutations. The disorder can lead to impaired blood clotting, resulting in prolonged or difficult-to-stop nosebleeds. Additional symptoms may include skin bruising and gum bleeding. Patients should strictly follow medical advice and use medications such as tranexamic acid tablets, vitamin K1 injection, or recombinant human coagulation factor VIII for treatment.

In daily life, patients are advised to use a humidifier to maintain indoor air moisture, avoid prolonged exposure to air-conditioned environments, and regularly use saline solution to moisturize the nasal passages, which can help reduce the occurrence of nosebleeds.
