It means that the level of a key protein in red blood cells called hemoglobin is higher than is typical. Hemoglobin carries oxygen throughout the body. It also gives red blood cells their color.<\/p>\n<p>Hemoglobin is measured in grams per deciliter (g\/dL) of blood. What&#8217;s considered a high hemoglobin count differs slightly from one lab to another. In general, a high hemoglobin count is more than 16.6 g\/dL for men and more than 15 g\/dL for women. In children, a high hemoglobin count varies with age and sex.<\/p>\n<p>Other factors that can affect hemoglobin count include:<\/p>\n<ul>\n<li>The time of day.<\/li>\n<li>How hydrated you are.<\/li>\n<li>How high above sea level you are.<\/li>\n<\/ul>\n<p>Most often, a high hemoglobin count happens when the body needs more oxygen. The body may need more oxygen due to:<\/p>\n<ul>\n<li>Smoking tobacco. This can lessen blood flow and cause less oxygen to reach the heart and lungs.<\/li>\n<li>Living high above sea level. Oxygen levels in the air are lower at high altitudes.<\/li>\n<\/ul>\n<p>Less often, a high hemoglobin count happens because:<\/p>\n<ul>\n<li>The body creates more red blood cells to make up for low oxygen levels due to heart or lung conditions.<\/li>\n<li>The bone marrow makes too many red blood cells.<\/li>\n<li>Some medicines or hormones cause the body to make more red blood cells. For example, lab-made versions of the sex hormone testosterone are a treatment for some men with low testosterone. This treatment is called testosterone replacement therapy, and it can cause a high hemoglobin count as a side effect.<\/li>\n<\/ul>\n<p>If you have a high hemoglobin count without other concerning test results, you likely don&#8217;t have a serious underlying condition. But some health conditions can cause a high hemoglobin count, including:<\/p>\n<ul>\n<li>Congenital heart disease in adults &mdash; one or more changes in the heart&#8217;s structure that are present at birth.<\/li>\n<li>COPD &mdash; a long-term lung disease that causes trouble with breathing.<\/li>\n<li>Dehydration &mdash; when the body doesn&#8217;t have enough water and other fluids to work as it should.<\/li>\n<li>Emphysema &mdash; a lung condition that causes shortness of breath.<\/li>\n<li>Heart failure &mdash; a condition in which the heart doesn&#8217;t pump blood as well as it should.<\/li>\n<li>Kidney cancer &mdash; cancer that starts in the kidneys.<\/li>\n<li>Liver cancer &mdash; cancer that starts in the liver.<\/li>\n<li>Polycythemia vera &mdash; a type of blood cancer.<\/li>\n<li>Obstructive sleep apnea &mdash; the most common sleep-related breathing condition.<\/li>\n<\/ul>\n<p>A very high hemoglobin count can lead to symptoms. Talk with your healthcare professional if you have symptoms such as:<\/p>\n<ul>\n<li>Trouble with vision.<\/li>\n<li>Dizziness.<\/li>\n<li>Headache.<\/li>\n<li>Slurred speech.<\/li>\n<\/ul>\n<p>Keep in mind that these symptoms can happen for many different reasons. It&#8217;s more common to find a high hemoglobin count during a routine blood test or a test checking for another condition. Your healthcare professional likely will do more tests to help figure out the cause of the high hemoglobin count.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>A high level of hemoglobin in the blood usually occurs when the body needs more oxygen, often because of smoking or living at high altitude.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","tags":[1686,1685,1682],"class_list":["post-52793","mayo","type-mayo","status-publish","hentry","tag-anatomical-structure","tag-condition","tag-person-group-concept","content_type-symptoms"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 -
