Short Answer
No. It is recommended to eat a light meal before donating blood.
Detailed Explanation
Donating on an empty stomach may increase the chance of dizziness, weakness, or fainting because your blood sugar levels may be low.
Eat a balanced meal about 2–3 hours before donation. Avoid skipping breakfast or lunch if your donation is scheduled later in the day.
Key Points
- Do not donate while fasting.
- Eat a light, healthy meal beforehand.
- Low blood sugar may cause dizziness.
- Stay hydrated as well.
❤️ A nourished donor is better prepared to save lives.
