THE fact that President Rodrigo Duterte is now back in the public eye after a week-long “private time” has not stopped, and will likely not stop, speculations about his state of health. Not after he was reported to have suffered a mild stroke, which reportedly affected one of his arms, and brought him to Cardinal Santos Medical Center in Greenhills last Thursday, where he reportedly also underwent a “peritoneal dialysis.” (PD is a treatment for early kidney disorder which, according to Wikipedia, uses the lining of your abdomen called peritoneum as a filter, and a cleansing solution called dialysate to clean your blood of waste and excess water. For advanced cases, hemodialysis is used to remove waste and excess water from the blood by circulating blood outside the body through an external filter called a dialyzer that contains a semipermeable membrane.)
