Abstract

Insights

A low-sodium diet with adequate water intake significantly improved hearing and reduced vertigo and tinnitus in Ménière's disease (MD) patients. This dietary approach offers a promising non-pharmacological treatment for managing MD symptoms effectively.

Area of Science:

  • Otorhinolaryngology
  • Neurology
  • Dietary Science

Background:

  • Ménière's disease (MD) is an idiopathic inner ear disorder.
  • Characterized by vertigo, hearing loss, tinnitus, and ear fullness.
  • Affects patients commonly in otorhinolaryngology practice.

Purpose of the Study:

  • To investigate the clinical efficacy of a low-sodium diet with adequate water intake in MD patients.
  • To assess the impact of dietary modifications on MD symptoms.
  • To evaluate the therapeutic effects on hearing, vertigo, and tinnitus.

Main Methods:

  • Fifty stage-3 unilateral MD patients were randomized into control and experimental groups.
  • Experimental group: low-sodium diet (1500 mg/d) and adequate water intake (35 ml/kg/d).
  • Both groups received routine medication; assessments included audiometry, electrocochleography, THI, and DHI.

Main Results:

  • Experimental group showed significant improvements in pure tone audiometry and electrocochleography (p < 0.05).
  • Markedly higher improvement in Tinnitus Handicap Inventory (THI) scores in the experimental group (p < 0.001).
  • Significantly greater reduction in Dizziness Handicap Inventory (DHI) scores in the experimental group (p = 0.004).

Conclusions:

  • A low-sodium diet combined with adequate water intake is effective for MD.
  • This dietary intervention improves hearing function in MD patients.
  • It significantly alleviates vertigo and tinnitus, enhancing quality of life.

Heart Failure Drugs: Diuretics01:22

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Antihypertensive Drugs: Action of Diuretics01:16

Antihypertensive Drugs: Action of Diuretics

Diuretics are antihypertensive drugs used to treat hypertension resulting from sodium and water retention. Sodium, vital for fluid balance and nerve or muscle function, is regulated by the kidneys through millions of nephrons. Blood enters nephrons via afferent arterioles, which branch into capillaries called glomeruli. These filter blood plasma, allowing water and solutes, like sodium ions, to pass through capillary walls into Bowman's capsule. The filtrate then flows through various...

Antihypertensive Drugs: Potassium-Sparing Diuretics01:28

Antihypertensive Drugs: Potassium-Sparing Diuretics

Liddle syndrome is a genetically inherited form of hypertension characterized by the overactivity of epithelial sodium channels in the nephron, the functional unit of the kidney. This heightened activity leads to increased sodium reabsorption and excessive excretion of potassium. To counteract this, potassium-sparing diuretics such as amiloride are used. They function by blocking these sodium channels, thereby reducing the influx of sodium into the epithelial cells and minimizing the loss of...

Antihypertensive Drugs: Thiazide-Class Diuretics01:15

Antihypertensive Drugs: Thiazide-Class Diuretics

Thiazide diuretics are sulfonamide derivatives featuring a benzothiadiazine ring system in their molecular structure. Based on this structure, thiazide diuretics can be categorized into two groups: thiazide-type and thiazide-like diuretics. Thiazide-type diuretics, including hydrochlorothiazide and chlorothiazide, consist of a benzothiadiazine backbone with an attached sulfonamide group. Thiazide-like diuretics, such as chlorthalidone and indapamide, lack the thiazide ring but demonstrate...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Regulation of Water Intake01:25

Regulation of Water Intake

Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...
