Smoking reduces the iron content

A regular blood test allows you to determine the presence of anemia unless you smoke. If you smoke, you may have anemia, even if the levels of hemoglobin that carries oxygen with blood flow are normal, studies have shown at the nutrition department of the Center for Disease Control in Atlanta.
That's what happens. Carbon monoxide contained in cigarettes, connecting with hemoglobin, forms a substance called carboxyhemoglobin. This form of hemoglobin does not have the ability to carry oxygen. To compensate for the deterioration in the supply of oxygen to the tissues, smokers have a higher hemoglobin level in the blood compared to non-smokers. Moreover, the more cigarettes you smoke, the more hemoglobin the test results will show, making it difficult to recognize possible anemia.
Researchers believe that to detect anemia in smokers, the lower values ​​of hemoglobin taken as the norm should be raised depending on the number of cigarettes smoked per day. For this reason, if you smoke, be sure to tell your doctor.
