What are the symptoms of dizziness and tinnitus, and what causes them?

If you experience dizziness and buzzing in your ears, you should pay attention, as these may be signs of physical problems. You can relax and rest for a few days to see if the condition improves. If not, you should go to the hospital for a detailed examination.

Causes of dizziness

Dizziness is caused by the dilation of blood vessels in the skin, increased blood flow and reduced blood flow to the brain. This phenomenon may be caused by prolonged exposure to the sun, taking a hot bath for too long, or being nervous or angry. In addition to the above reasons, vitamin deficiency, abnormal hormone secretion, menopause or autonomic nervous system disorders are also factors that cause dizziness.

There are two main causes of tinnitus: one is caused by ear diseases and the other is caused by systemic diseases.

1. Otogenic tinnitus:

⑴ Lesions of the sound-transmitting part (external ear and middle ear): cerumen embolism in the external auditory canal, external auditory canal eczema, myringitis, otitis media, and Eustachian tube dysfunction. The tinnitus caused by this type of disease is generally not serious and will disappear after the cause is eliminated.

⑵ Lesions of the sensory part (inner ear): Meniere's disease, noise-induced hearing loss, ototoxic food poisoning, sudden deafness, etc. The tinnitus caused by this type of disease is more serious.

⑶ Retrocochlear lesions (acoustic nerve): Hunter syndrome, acoustic neuritis, acoustic neuropathy, acoustic neuroma.

⑷ Lesions of the auditory center (the auditory conduction pathway from the cochlear nerve nucleus to the auditory cortex of the brain): efferent nerve dysfunction, cerebral hemorrhage, dorsolateral medulla syndrome, etc. The tinnitus caused by this type of lesion is very stubborn.

2. Tinnitus caused by systemic diseases:

⑴ Cardiovascular and cerebrovascular diseases: hypertension, hypotension, anemia, coronary heart disease, arteriosclerosis, cerebral thrombosis, hemangioma, arteriovenous aneurysm. This type of disease often causes pulsating tinnitus that is consistent with the pulse.

⑵ Cervical spondylosis: cervical vertebrae A are compressed by bone hyperplasia or herniated disc.

⑶ Brain trauma or nervous system disease: head trauma, concussion, encephalitis, meningitis. This type of disease often causes tinnitus and sensorineural hearing loss with high-frequency hearing loss.
