Have you ever had a nosebleed for no reason while sleeping? It doesn’t bleed enough to cause a nosebleed, but it often bleeds when you wipe it with a tissue. This happens especially often when you’re drunk and fall asleep.
There can be many reasons for nosebleeds. Most people know what causes nosebleeds. For example, the most common causes are nosebleed habits, children playing with foreign objects in the nose, or trauma to the nose or face. Additionally, breathing dry, cold air or being in a dusty environment can also cause nosebleeds.
However, if you have frequent nosebleeds even though there is no cause of injury or irritation, or if the nosebleeds do not easily subside, you may have a blood clotting problem or various diseases.
Let’s find out what causes nosebleeds.
Allergic rhinitis
Allergic rhinitis is a disease that causes symptoms such as itching, sneezing, and runny nose in the area around the nose and eyes. These symptoms are usually caused by exposure to allergens such as dust or pollen. Therefore, if you experience nosebleeds or runny nose along with sneezing, you may have allergic rhinitis.
Dry air
Dry climates or hot indoor environments can dry out the nasal passages, making them more prone to bleeding. This condition is usually not associated with a specific disease, but can be managed with humidifiers and nasal moisturizers.
Blood disorders
Certain blood disorders, such as hemophilia or von Willebrand disease, can cause excessive bleeding, including nosebleeds.
Medications
Some medications, such as blood thinners (anticoagulants) or nasal sprays, may increase the chance of nosebleeds. It is also a drug such as an anticoagulant or thrombolytic agent taken to treat cardiovascular diseases such as myocardial infarction, angina, and arrhythmia. These medications prevent the blood from clotting or dissolving blood clots, so taking too much can cause the blood to become too thin and bleed easily.
Sinusitis
Sinusitis is a disease that causes inflammation in the nasal cavity and paranasal sinuses, and symptoms include nosebleeds, dry cough, sore throat, and fever. These symptoms are usually caused by viruses or bacteria. If you have nosebleeds and are accompanied by a dry cough or sore throat, you may have sinusitis.
Septal ptosis
Septal ptosis is a disease that occurs when mucus secreted around the nose and mouth accumulates instead of flowing into the drainage tube. These diseases are usually congenital, and symptoms such as sinusitis or sore throat may appear along with nosebleeds.
Nasal tumor
Nasal tumors are tumors that occur in the nasal cavity and cause symptoms such as nosebleeds, bleeding, nasal congestion, and sinus fullness. These tumors are generally more benign than malignant and are usually curable if detected and treated early.
Septal atresia
Septal atresia has similar symptoms to septal ptosis, but is a disease that occurs when the sewer pipe is completely blocked. These conditions are usually congenital and cause symptoms such as nosebleeds, sinus fillings, or sore throats.
Tumors in the nasal cavity
Intranasal tumors are tumors that occur inside the nasal cavity and are usually benign. These tumors typically cause symptoms such as bleeding, nasal congestion, and sinus filling. Therefore, if these symptoms appear along with nosebleeds, an intranasal tumor may be suspected.
Bronchial asthma
Bronchial asthma is a disease in which the bronchi become narrow and inflamed, making breathing difficult. These diseases often cause symptoms such as nosebleeds, sneezing, and runny nose, along with breathing sounds characteristic of asthma patients.
High blood pressure
Uncontrolled high blood pressure can cause nosebleeds.
Liver disease
Advanced liver disease can affect blood clotting factors and potentially cause nosebleeds.
