Hearing & Cholesterol
High LDL (“bad”) cholesterol levels interfere with our inner ear function, which can result in hearing loss (1,2,3). Some researchers have also found correlations between high cholesterol levels and other inner ear disorders (1).
NOISE EXPOSURE AND CHOLESTEROL
High blood lipid levels (including cholesterol) places us at even greater risk than usual for noise-induced hearing loss (1). High lipid levels in the blood are more common in patients with noise-related hearing loss than in people with normal hearing (4). The relationship between noise exposure and cholesterol may ‘work both ways’, as noise exposure can actually increase cholesterol levels! (1)
The good news is, keeping your blood lipid levels ‘in check’ can reduce your risk of hearing loss and tinnitus(ear noises) (1,4).
PREVENTION IS THE GOAL!
Audiologists monitor ear health, not just ‘hearing loss’. Talk to your Audiologist about prevention of hearing loss.
