There is no dispute that hypoxia is harmful to health. The question is is hypoxia prevalent in our daily life. Our answer is "Yes" though we are sure there are plenty who may say the other way.

Our question is rephrased: Is hyperlipidimia, hyperglycemia, or overproduction of free radical common in our daily life? We are sure most people will choose "yes". In fact this question is equivalent to the former one because either of hyperlipidimia, hyperglycemia, or over-production of free radical causes hypoxia.

Oxygen uptake by tissues is predominantly decided by the number of Red Blood Cells(RBC)s succesfully squeezed into capillary vessel. When RBCs are less deformable they will flow directly to vein without passing the capillary, not to mention unloading oxygen they carry. This part is widely accepted by medical science. However weird enough, it is totally ignored by clinical practice. We point less deformable RBC as culprit for most of modern chronic diseases.

What factors do cause RBC less deformable? Hyperlipidimia, hyperglycemia, and overproduction of free radicals. We recomment you read our fresh article on Diabetes mellitus to know more about it.
