Hemoglobin performs one of the most important functions in the blood, since it carries oxygen in its cells, which enters all organs of the body. An increase in hemoglobin levels can be a sign of the presence of certain diseases that can threaten a person's health.
For men, the norm for hemoglobin is 17.5 g / dl. In women, the hemoglobin concentration is slightly lower and should not exceed 15.5 g / dl. If the patient has deviations of this indicator as a result of a blood test, the doctor may need to carry out additional diagnostic procedures to identify the reasons that caused the increase in the amount of the substance.
The reasons for the increase in hemoglobin
Hemoglobin rises with an increased production of blood cells, which compensate for the 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 if the kidneys are not functioning properly or as a result of taking drugs that stimulate the production of red blood cells. An increase in hemoglobin indices can also occur due to dysfunction of the spinal cord, during a long stay at a high altitude (for example, in the mountains), where the oxygen content is slightly lower and the body is required to take measures that allow it to obtain sufficient amounts of the necessary substances for the normal functioning of organs and fabrics.
An increase in the level of hemoglobin occurs only under the influence of certain factors and in itself is not dangerous. However, the presence of a large number of red cells may indicate a serious pathology that must be treated under the supervision of a doctor. Common causes of high red cell counts include pulmonary emphysema, liver or kidney cancer, heart disease, pulmonary obstruction, congenital heart failure, and dehydration. If the hemoglobin norm is exceeded, the doctor is obliged to prescribe additional studies that will clarify the diagnosis and make it possible to determine the exact reason for the increase in this indicator in the blood.
Excessive hemoglobin levels can raise blood pressure. In patients with a change in the composition of the blood, headaches, redness of the skin, sleep disorders and a drop in general well-being may begin. High hemoglobin can indicate the presence of blood disorders in the human body, which should also be corrected.
Increased hemoglobin levels caused by organ dysfunction increase the thickness and viscosity of the blood, which also increases the risk of blood clots and subsequent vascular occlusion. This process can lead to heart attacks, heart attacks and strokes in a person.
To stabilize the patient's condition, the attending physician may prescribe blood-thinning drugs (for example, "Curantil", "Trental" or "Cardiomagnet"). Medicines are prescribed only by a specialist at the time of finding out the reason for the increase in hemoglobin levels and making a diagnosis of the disease.
