What causes dizziness? Women's health must know

Dizziness is a very common physiological phenomenon in life, which often manifests as discomfort such as brain swelling, a sense of spinning, and mental fatigue, which has a great impact on people's lives. So what are the specific causes of dizziness?

1. Otogenic dizziness

Otogenic dizziness is true vertigo, and its dizziness symptoms are often more severe. There are generally no symptoms of cranial nerve and brain parenchyma damage, only manifestations such as dizziness due to ear damage. Common causes of ear-related dizziness include: external ear lesions, such as bite compression, foreign body obstruction, etc.; middle ear lesions, such as middle ear moxibustion, tympanic membrane retraction or calcification, otosclerosis, Eustachian tube obstruction, etc.; inner ear lesions, such as labyrinthitis, motion sickness, labyrinth trauma, positional vertigo, allergic reaction, inner ear vascular disease (anterior chamber stroke), vestibular poisoning, special inner ear infection, etc.

2. Neuropathy causes dizziness

Dizziness caused by neuronal diseases is mostly due to damage to intracranial nerves or brain parenchyma. The dizziness is generally severe and the symptoms last longer. Common causes include: inflammatory diseases, such as vestibular neuronitis, brainstem, cerebellum, meningitis, etc.; vascular diseases, such as thrombosis of the posterior inferior cerebellar artery, vertebral-basilar artery blood supply obstruction, cervical vascular nerve compression syndrome, subarachnoid hemorrhage, cerebellar hemorrhage, etc.; in addition, brain tumors compressing neurons, intracranial hypertension, etc. can cause dizziness and even some craniocerebral trauma, such as craniocerebral trauma, brainstem, small intestine injury, petrous bone fracture, etc. can also cause neuron damage and cause dizziness symptoms.

3. Ocular dizziness

Ocular dizziness is characterized by worsening dizziness when looking at objects with eyes open and less fatigue or disappearance when eyes closed. It is mostly caused by eye muscle disease, refractive error, glaucoma or visual impairment.

4. Dizziness due to systemic diseases

Dizziness caused by systemic diseases usually does not cause a sense of visual rotation, and is often manifested as dizziness and unsteady standing, and is accompanied by physical illness. Common diseases that cause dizziness include: cardiovascular diseases, such as hypertension, hypotension, arteriosclerosis, heart disease, vasculitis and carotid sinus syndrome; systemic infections and poisoning diseases, such as fever, cholecystitis, lung infection, carbon monoxide poisoning, etc.; endocrine and metabolic diseases: such as hyperlipidemia, diabetes, hypoglycemia, abnormal thyroid function, menopausal syndrome; blood diseases, such as polycythemia, hypercoagulability, anemia, etc.; and other diseases such as chronic cerebral hypoxia caused by various reasons, migraine, tumors, etc.
