Intermittent Lightheadedness: Advice and Management

Overview

Intermittent lightheadedness is a common symptom that can often be managed with simple lifestyle adjustments. The following advice is intended to help reduce episodes and improve your day-to-day wellbeing.

Fluid and Salt Intake

• Increase fluid intake to at least 2 litres per day
• Increase salt intake to 6–10g per day

Adequate hydration and salt intake help maintain blood volume and blood pressure, reducing the likelihood of lightheadedness, particularly on standing.

Lifestyle Adjustments

• Wear compression stockings to support blood flow from the legs back to the heart
• Avoid large meals — eat smaller amounts more frequently to prevent post-meal drops in blood pressure
• Avoid alcohol or cut down significantly, as it causes blood vessel dilation and can worsen symptoms
• Avoid caffeine, taurine, and similar stimulants, which can affect heart rhythm and blood pressure

Medication Review

Some medications can contribute to lightheadedness, particularly those that lower blood pressure. If you suspect a medication may be a contributing factor, please contact us before stopping anything, so we can review your prescription and make any necessary adjustments safely.
