A
condition in which a higher-than-normal amount of
methemoglobin is found in the
blood. Methemoglobin is a form of
hemoglobin that cannot carry
oxygen. In
methemoglobinemia, tissues cannot get enough oxygen. Symptoms may include headache, dizziness,
fatigue, shortness of breath,
nausea, vomiting, rapid heartbeat, loss of muscle coordination, and blue-colored skin. Methemoglobinemia can be caused by injury or being exposed to certain drugs, chemicals, or foods. It can also be an
inherited condition.
