Hemoglobin and Your Health
Most of the iron in your body is found in the hemoglobin molecule of your red blood cells.
For the safety of both donor and patient, your hemoglobin level must be at least 12.5/g/dL for women and 13.0 g/dL for men to give blood.
Causes of low hemoglobin
The most common causes of a low hemoglobin count are:
- A low-iron diet
- Frequent blood donation
- Menstrual blood loss
Other less likely but more serious causes of low hemoglobin include arthritis, diabetes, kidney disease, stomach ulcers, colon cancer, medications, and other diseases of the digestive tract. Consult your doctor if you want to rule out these possibilities.
How to raise your hemoglobin
The best way to get enough iron is to have a healthy, well-balanced diet.
Heme iron, found in meat, fish, and poultry is more easily absorbed by the body than non-heme iron, which is found in plant sources. The absorption of iron from non-heme sources is enhanced when vitamin C is eaten at the same meal or snack. Conversely, some foods hinder the absorption of iron.
