What happens when hemoglobin levels increase in your body?

hemoglobin is a protein, helps store energy in the cells

==================================

Haemoglobin, a protein, is rather known as the oxygen/carbon dioxide carrier. Tucked safely inside the red blood cells, they bind to oxygen molecules from the lungs (alveoli) (four oxygen molecules per haemoglobin), and carry them, in the blood stream, to the tissues. While at the tissues, they release the oxygen as needed. Haemoglobins also carry carbon dioxide from the tissues to the alveoli, where the carbon dioxide molecules are released. (gas exchange).
