Physical Changes
There are a couple of physical changes that you might notice when hypoxia and hypoxemia progress. In some cases, your fingernail beds or lips might experience blue discoloration, a condition known as cyanosis. It indicates a low level of oxygen in your bloodstream when hypoxemia occurs. Also, unexpected weight loss would happen in some advanced stages when your body needs more energy to breathe. Both hypoxemia and hypoxia deplete your body of important calories which should be spent for maintenance. Last but not least, you would also have swelling in your legs or feet if the conditions are left untreated for an extended period. [5]
