Giddiness

Giddiness may feel like light-headedness, dizziness, or unsteadiness. It may occur briefly or persist over time. There are many possible causes, including problems with balance, dehydration, medications, or changes in blood circulation. One common cause is low blood pressure, where reduced blood flow to the brain can lead to a dizzy or faint feeling. In such cases, it may be helpful to check your blood pressure, especially if symptoms occur when standing up or changing position.

Visit the Emergency Department if you have any of the following:

• Giddiness accompanied by sudden severe headache, chest pain, or blurred vision.
• Giddiness accompanied by sudden onset of one-sided weakness, numbness or difficulty speaking. (Call 995 if these accompanying symptoms started within the last 6 hours)
• Giddiness after a head injury.
• Giddiness with fainting.
• Persistent giddiness affecting your ability to stand or walk.
• Giddiness with a high fever, persistent vomiting, or other signs of dehydration.

Visit the GP or Polyclinic if you have any of the following:

• Mild, occasional giddiness that you suspect is related to a minor illness, like a cold or a sinus infection.
• Giddiness that is long-standing with known triggers

What you can do:

• Sit or Lie Down Immediately: This is the most crucial step. Sitting or lying down will help you regain your balance and prevent a potential fall. If you're walking, grab a stable object for support. Do not stand up immediately but take a moment to sit on the edge of the bed or chair before standing fully.
• Elevate Your Feet (If Lying Down): If you lie down, slightly elevate your feet. This helps encourage blood flow back to your head, which can be helpful if the giddiness is caused by a drop in blood pressure.
• Stay Still and Focus: Close your eyes or focus on a fixed point in the distance. Avoid sudden head movements, looking at moving objects or people, which can worsen the sensation of unsteadiness.
• Drink Water and Replenish Electrolytes: Dehydration is a common cause of giddiness. Sip on some water slowly. If you've been sweating a lot, consider a sports drink or an electrolyte solution to replenish lost minerals.
• Eat a Small, Quick Snack: Giddiness can be a symptom of hypoglycaemia, especially in people with diabetes. Having a small snack with carbohydrates, like a piece of fruit, crackers, or a small glass of juice, can help normalise low blood sugar levels.
• Stress Reduction Exercises: Giddiness can be a physical manifestation of anxiety or a panic attack. When you feel a dizzy spell coming on, take slow, deep breaths. Inhale for a count of four, hold for a count of four, and exhale for a count of six. Alternatively, try a mindfulness exercise, listen to a calming piece of music, or take a short walk to help manage stress.
