Which of the following actions can help prevent attacks of Meniere's disease?

Avoiding sudden movements is a beneficial strategy for individuals who experience Meniere's disease, as this condition is characterized by episodes of vertigo, tinnitus, and hearing loss, often related to changes in inner ear pressure. Sudden movements can exacerbate symptoms by triggering vertiginous episodes. This precaution helps to maintain balance and reduces the likelihood of triggering an episode by ensuring that movements are gradual and controlled.

In contrast, while limiting physical exercise might seem reasonable, moderate activity can actually be beneficial for overall health. Increasing fluid intake may not be universally helpful, as the recommendation can vary; in some cases, dietary sodium restrictions and fluid management are emphasized rather than simply drinking more fluids. Engaging in balance training can also assist with overall stability but might not directly prevent Meniere's attacks. Therefore, the focus on avoiding sudden movements directly aligns with the goal of minimizing symptom triggers.
