Etiology and Treatment of Fluid Retention (Hydrops) in Ménière's Syndrome

Abstract

For years low sodium diets have been recommended in the treatment of Ménière's syndrome. Elevated levels of insulin play an important role in sodium retention in renal tubules. Insulin production is stimulated by high carbohydrate diets. Adrenaline, cortisone, and glucagon levels may he increased by stress or food or inhalant allergies, further elevating insulin levels. The end result of prolonged hyperinsulinemia includes vasoconstriction and eventually arterial smooth muscle hypertrophy. Individual susceptibility to Ménière's syndrome may occur as a reult of inflammatory changes in the endolymphatic sac or cochlear aqueduct secondary to primary or latent viral infections, thus predisposing to fluid retention. Long term medical treatment of Ménière's should be directed towards preventing sodium retention through sodium restriciton and carbohydrate management. Other factors including stress and allergy should also be considered.
