As a result, an individual’s blood pressure is lower than usual, which reduces blood flow to the brain. These changes increase the blood flow to the developing baby, but they also mean a slow return of blood in the veins to the rest of the body. Hormonal changes appear to play a role, as they affect the characteristics of the fluid in the body and cause blood vessels to relax and widen. Nausea and dizziness are usual problems during pregnancy. acoustic neuroma, which is a benign growth that develops on the vestibulocochlear nerve near the inner ear.a stroke or a transient ischemic attack, which people sometimes refer to as a ministroke.ataxia, which is the result of muscle weakness.otosclerosis, when a middle ear bone growth problem leads to hearing loss.shingles in or around the ear - herpes zoster oticus.perilymphatic fistula, when inner ear fluid leaks into the middle ear due to a tear in either of the two membranes between the middle ear and inner ear.People typically experience periods of vertigo that last less than 60 seconds, but nausea and other symptoms may also arise. There, each fallen crystal touches sensory hair cells during movement.Īs a result, the brain receives inaccurate information about a person’s position, and spinning dizziness occurs. In BPPV, these crystals become dislodged and fall into the semicircular canals. The otolith organs are structures within the inner ear that contain fluid and particles of calcium carbonate crystals.
Benign paroxysmal positional vertigo (BPPV) There may also be a genetic component, meaning that it runs in some families.įind out more about Ménière’s disease here. The exact cause is unclear, but it may stem from blood vessel constriction, a viral infection, or an autoimmune reaction. The National Institute on Deafness and Other Communication Disorders estimates that 615,000 people in the United States currently have a diagnosis of Ménière’s disease, with doctors diagnosing about 45,500 new cases annually. It tends to be more common in people between 40–60 years old.
This disease causes a buildup of fluid in the inner ear, which can lead to attacks of vertigo with ringing in the ears and hearing loss. As it grows behind the eardrum, it can damage the middle ear’s bony structures, leading to hearing loss and dizziness.

This noncancerous skin growth develops in the middle ear, usually due to repeated infection. Vestibular neuritis causes vertigo that may accompany blurred vision, severe nausea, or a feeling of being off-balance.įind out more about vestibular neuritis here. It is similar to labyrinthitis but does not affect a person’s hearing.
Vestibular neuritisĪn infection causes vestibular neuritis, which is inflammation of the vestibular nerve. This nerve sends information to the brain about head motion, position, and sound.Īpart from dizziness with vertigo, a person with labyrinthitis may experience hearing loss, tinnitus, headaches, ear pain, and vision changes. Within this area is the vestibulocochlear nerve. This disorder can happen when an infection causes inflammation of the inner ear labyrinth. Various conditions can lead to vertigo, which usually involves either an imbalance in the inner ear or a problem with the central nervous system (CNS).Ĭonditions that can lead to vertigo include the following.
