Hemoglobin

What is hemoglobin?

The tests confirmed that she has low blood pressure and low hemoglobin.

Too few red blood cells or too little hemoglobin in the blood can lead to anemia.

Researchers say it makes sense that loss of hearing might be caused by anemia. The inside of the ear is very sensitive to oxygen, and it's possible that the nerves there are not getting enough in someone who is iron-deficient. Iron is an essential element for the production of hemoglobin, the red blood cell protein that carries and releases oxygen throughout the body.

The authors pointed to studies that have shown the benefits of social interactions in health care. For example, in one investigation, patients who talked on the phone weekly with a peer saw a more significant drop in a marker of diabetes, called glycated hemoglobin levels, than those who worked only with clinicians.

The American Congress of Obstetricians and Gynecologists, in an opinion from its Committee on Obstetric Practice that was published on the ACOG website, said that instead of quickly clamping off the cord that connects the newborn to its placental sac, doctors should wait an additional 30 to 60 seconds. Those extra seconds for babies born at term are associated with an increase in hemoglobin levels in newborns, the statement said.
