Low-sodium diet with adequate water intake improved the clinical efficacy in Ménière's disease.

BACKGROUND

Ménière's disease (MD) is a common idiopathic inner ear disorder in otorhinolaryngology characterized by recurrent episodes of vertigo, fluctuating sensorineural hearing loss, tinnitus and ear fullness.

OBJECTIVE

To study the effects of low-sodium diet with adequate water intake on the clinical efficacy in MD.

METHODS

Fifty patients diagnosed with stage-3 unilateral MD were randomly divided into control group( = 25) and experimental group( = 25). The control group was given routine medication therapy, and the experimental group was restricted to an sodium intake of 1500 mg/d and a water intake of 35 ml/kg/d based in addition to the routine medication therapy. The two groups were assessed using pure tone audiometry, electrocochleography, Tinnitus Handicap Inventory (THI), and Dizziness Handicap Inventory (DHI).

RESULTS

The pure tone audiometry and electrocochleography showed better improvements after treatment in the experimental group than the control group ( < 0.05). The THI improved values in the experimental group were significantly higher than the control group ( < 0.001). The DHI improved values in the experimental group were significantly higher than the control group ( = 0.004).

CONCLUSIONS AND SIGNIFICANCE

Low-sodium diet with adequate water intake improved the hearing and alleviated vertigo and tinnitus in MD patients.
