DEAR DR. ROACH: About a year ago, my son was diagnosed with polycythemia. No one in our family had ever heard of this. He goes in every four to six weeks to have a pint of blood removed. Now he has been diagnosed with sleep apnea, which the doctor says caused the polycythemia, as his blood wasn't getting enough oxygen and so it overproduced red blood cells to compensate.
Will the polycythemia go away once he gets more oxygen with the CPAP equipment he now uses? -- S.R.
