Introduction

Influenza refers to the flu. Generally, if the influenza virus affects the normal functioning of the nervous system, flu patients may experience dizziness. If the influenza virus does not interfere with the nervous system, dizziness may not occur. If in doubt, it is recommended to consult a physician. After infection with the influenza virus, the body's immune system quickly initiates defensive mechanisms.

　　Influenza refers to the flu. Generally, if the influenza virus affects the normal function of the nervous system, patients with influenza may experience dizziness. Conversely, if the influenza virus does not interfere with the nervous system, dizziness may not occur. If in doubt, it is recommended to consult a physician. Detailed analysis is as follows:

　　After infection with the influenza virus, the human immune system quickly activates its defense mechanisms. The virus multiplies extensively in the body, and if it affects the normal function of the nervous system, disrupting oxygen supply to the brain and neural signal transmission, it can cause dizziness. This is often accompanied by physical weakness and mental fatigue, making movement difficult for the patient.

　　In some patients infected with the influenza virus, the damage to the body is limited, and the virus does not trigger a strong systemic response. With minimal toxins interfering with the nervous system and no significant cerebral hypoxia caused by high fever, the brain's normal functions are maintained. Therefore, these patients may not exhibit dizziness but might only show localized respiratory symptoms such as mild coughing and a runny nose, with relatively mild overall discomfort.

　　In daily life, maintaining fresh indoor air by regularly opening windows for ventilation helps dilute the influenza virus concentration with fresh air, thereby reducing the risk of infection.

Can sinusitis cause headaches and dizziness?

If sinusitis is in the acute exacerbation phase, congestion and swelling of the mucous membranes within the sinuses, along with accumulation of secretions, can compress surrounding sinus tissues and stimulate nerves, causing significant headaches. The location of the pain typically corresponds to the affected sinus (for example, maxillary sinusitis causes pain in the cheek area). If the inflammation impairs nasal airflow, leading to a mild reduction in cerebral oxygen supply, it may also be accompanied by mild dizziness. Symptoms gradually subside as the inflammation resolves.

Why do I feel dizzy after taking Ornidazole capsules?

A lower than normal number of red blood cells or hemoglobin levels in the body leads to insufficient oxygen and blood supply to the brain. Taking ornidazole capsules may worsen dizziness.
