Introduction
In general, dizziness, nausea, and nosebleeds may be caused by dry weather, excessive fatigue, acute rhinitis, hypertension, thrombocytopenia, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve symptoms under a doctor's guidance through general measures, medication, or other treatments. In daily life, avoid forcefully picking the nose or vigorous nose-blowing to maintain the integrity of the nasal mucosa.
Generally, dizziness, nausea, and nosebleeds may be caused by dry weather, excessive fatigue, acute rhinitis, hypertension, thrombocytopenia, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and then improve symptoms under a doctor's guidance through general management, medication, and other treatments. Specific analyses are as follows:
1. Dry Weather: In dry environments, nasal mucosa loses moisture, becoming fragile and prone to rupture and bleeding. Blood loss combined with nasal discomfort can lead to dizziness and nausea. Use a humidifier indoors to maintain humidity at 50%-60%, moisten the nasal cavity daily with saline solution, and when experiencing a nosebleed, lean forward and pinch the nostrils for 10 minutes to stop the bleeding.
2. Excessive Fatigue: Long-term sleep deprivation or high-intensity work can exhaust the body, causing abnormal blood vessel regulation, nasal vessel rupture and bleeding, along with insufficient cerebral blood supply leading to dizziness and nausea. Immediately stop working, rest in bed, ensure 7–8 hours of sleep per day, and increase nutrient-rich foods such as lean meat and eggs in the diet.
3. Acute Rhinitis: Viral infections cause nasal inflammation, resulting in congested and swollen mucosa that bleeds easily. The spread of inflammation throughout the body can lead to dizziness and nausea. Follow your doctor’s instructions to use medications such as *Biyan Tongqiao Granules*, cefuroxime axetil tablets, and naphazoline hydrochloride nasal drops to reduce inflammatory irritation.
4. Hypertension: A sudden rise in blood pressure increases stress on nasal blood vessels, causing them to rupture and bleed. Blood pressure fluctuations can also trigger cerebral vascular spasms, resulting in dizziness and nausea. Follow your doctor’s instructions to use antihypertensive medications such as nifedipine controlled-release tablets, valsartan capsules, and hydrochlorothiazide tablets to control blood pressure.
5. Thrombocytopenia: Insufficient platelet count leads to impaired coagulation function, making nosebleeds more likely and harder to stop. Excessive blood loss can result in dizziness and nausea. Follow your doctor’s instructions to use medications such as prednisone acetate tablets, aptamine tablets, and leucogen tablets to increase platelet levels.
In daily life, avoid forcefully picking the nose or blowing it vigorously to maintain the integrity of the nasal mucosa. Maintain a light diet, eat more fruits and vegetables rich in vitamin C, and reduce intake of spicy and irritating foods. Keep a regular schedule, exercise appropriately to strengthen physical health, and maintain emotional stability to prevent discomfort caused by blood pressure fluctuations.
