What causes an increase in hemoglobin?

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.

Is there such a thing as 'reverse altitude sickness'?

Humans can certainly experience reverse altitude sickness, known as high-altitude de acclimatisation syndrome (HADAS). When people who live at low altitude have adjusted to a high-altitude, low-oxygen environment, they can get any of a large number of possible symptoms of HADAS when returning to a lower altitude.

Why does the hemoglobin level rise at high 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.

What are some challenges humans face at high altitude?

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
