Acne occurs when the pores on your skin become blocked with oil, dead skin, or bacteria. Each pore on your skin is the opening to a follicle. The follicle is made up of a hair and a sebaceous (oil) gland. The oil gland releases sebum (oil), which travels up the hair, out of the pore, and onto your skin. The sebum keeps your skin lubricated and soft. Acne can be caused by one or more problems in this lubrication process.

Anemia is defined as a hemoglobin level of less than 120 g/L in non-pregnant females and less than 130 g/L in males. Anemia is related to symptoms such as fatigue and lowered exercise tolerability. If your hemoglobin level is below 110 g/L, you should see your physician for further testing. If anemia is present, you should not return to donate until the cause of the low hemoglobin has been identified and corrected.
