Yes, oxygen is lower in higher altitudes
At high attitudes, hypoxia-induced erythropoietic drive results in erythrocytosis and an increase in hemoglobin concentration and hematocrit. Hence people with SCD should be careful and report abnormalities to the doctor immediately.
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
Avoid visiting places on the same day when you get to higher altitudes. Acclimatise and only then get to places which requires climbing.
High hemoglobin levels can lead to dizziness, fatigue, easy bruising and other symptoms.
