10 Side Effects of Low Iron

Low Iron Side Effect #1: Light-Headedness
The brain is a powerful organ and, as is usual for something so powerful, it needs a lot of fuel to keep it going. This means that lots of oxygen-rich blood needs to be constantly pumped to the brain at all times. If there is not enough oxygen going to the brain then it can begin to struggle. A sensation of dizziness may occur as a result.
With insufficient hemoglobin in the blood to carry oxygen to the brain, then light-headedness is likely to result. This can also cause the blood vessels in the brain to expand and this can result in headaches. If these symptoms exist then you should see a doctor regardless of the suspected cause.
