High hemoglobin levels can lead to dizziness, fatigue, easy bruising and other symptoms.
Yes, oxygen is lower in higher altitudes
At higher altitudes such as on top of a mountain, the air is less dense and this means that the partial pressure of oxygen is lower. Hence, the fall in atmospheric pressure at higher altitude decreases the partial pressure of inspired oxygen
High altitudes can cause low oxygen saturation levels or desaturation of an individual's blood. It happens because of low atmospheric pressure at high altitudes. Oxygen saturation levels refer to the extent hemoglobin is bound or saturated to oxygen.
High hemoglobin level is most often caused by low oxygen levels in the blood (hypoxia), present over a long period of time. Common reasons includes bone marrow disease that causes abnormal increase in red blood cells (polycythemia vera) Congenital heart disease and heavy smoking.
