Whether elevated hemoglobin level is dangerous

Hemoglobin Norm

For men, the norm of hemoglobin is 17.5 g/dL. In women, hemoglobin concentrations are slightly lower and should not exceed 15.5 g/dL. If the patient’s blood test detected deviations of this indicator, the doctor may need to perform additional diagnostic procedures to identify the causes that caused increasing the amount of substance.

Causes of hemoglobin

increase Hemoglobin are increased with increased production of blood cells, which compensate for lack of oxygen in human organs and tissues. This phenomenon occurs due to insufficient function of the heart or lungs. Also, hemoglobin levels can increase when the kidneys are malfunctioning or as a result of taking drugs that stimulate the production of red blood cells. Increased hemoglobin rates may also occur due to spinal cord dysfunction, with long stays at high altitude (such as mountains), where oxygen content is somewhat lower and from the body measures are required to allow sufficient availability of the necessary substances for the normal functioning of organs and tissues.

Increasing hemoglobin levels occurs only under the influence of certain factors and is not dangerous in itself. However, the presence of a large number of red cells may speak to a serious pathology that needs to be treated under the supervision of a doctor. Among the frequent causes of large numbers of red cells are pulmonary emphysema, liver or kidney cancer, heart disease, lung obstruction, congenital heart function disorders and dehydration. If the norm of hemoglobin is exceeded, the doctor is obliged to prescribe additional studies, which will allow to clarify the diagnosis and give the opportunity to determine the exact cause of increase


Excessive hemoglobin content can increase blood pressure. In patients with a change in blood composition, headaches, redness of the skin, sleep disorders and a drop in general well-being can begin. High hemoglobin can tell about the presence in the human body of disorders in the composition of the blood, which are also worth correcting.

Increased hemoglobin content caused by organ dysfunction increases blood density and viscosity, which also increases the risk of blood clots and subsequent blockage of vessels. This process can lead to heart attacks, heart attacks and human strokes.

To stabilize the patient’s condition, the attending physician may prescribe blood-thinning drugs (e.g., “Kurantil”, “Trental”, or “Cardiomagnil”). Medicines are prescribed only by a specialist at the time of finding out the cause of the increase in hemoglobin levels and diagnosis of the disease.
