You’re right, O+ is indeed the most common blood type, followed by A+. In many populations, AB+ is rare, but rarity doesn’t mean there’s any inherent issue with it. It’s just a matter of genetics. Having AB+ means you can receive red blood cells from any blood type in an emergency transfusion, which is actually a bit of an advantage. You don’t necessarily need to be concerned about this in your daily life, unless a medical situation arises where blood transfusion is involved.
Feeling lightheaded can have many causes, and it’s usually not related to your blood type. It’s more sensible to consider other factors like diet, hydration, or even stress. Since you mention diet, it might be worth looking at whether you’re consuming enough iron-rich foods like leafy greens, nuts, seeds, and lentils, which support healthy blood and circulation. Paying attention to eating at regular intervals could also stabilize blood sugar levels, reducing lightheadedness.
In terms of whether your blood type should dictate your diet, there’s limited scientific support for the Blood Type Diet, which suggests certain foods for different blood types. It’s usually more beneficial to focus on a balanced diet tailored to your individual constitution, or ‘prakriti’, in Ayurvedic terms. Consider whether your current dietary habits align with your dosha balance and digestive fire, or ‘agni’.
If your lightheadedness persists or worsens, or if it’s accompanied by other symptoms like palpitations or severe fatigue, it’s important to seek medical advice to rule out more serious conditions. Meanwhile, maintaining hydration, regular meals, and stress management might help alleviate some of the symptoms you’re feeling.
