What is a Placebo. A placebo (or dummy pill) is an inert substance, typically a tablet, capsule or other dose form that does not contain an active drug ingredient. For example, placebo pills or liquids may contain starch, sugar, or saline. Physical placebo, or âshamâ treatments have also been used, such as inactive acupuncture devices.
en espaÃ±olReflujo vesicoureteral (VUR) We've all heard of acid reflux â when stomach acids move up into the esophagus and cause a burning sensation â but there can be other types of reflux in the body. When urine (pee) refluxes from the bladder to the kidneys, it's called vesicoureteral reflux (VUR). Vesicoureteral (ves-ih-koe-yoo-REE-ter-ul) reflux happens when urine abnormally flows backward from the bladder into the ureters, thin tubes that connect the kidneys to the bladder.
Causes of Reflux. Normal, physiologic reflux is thought to be caused by relaxation of the muscle between the esophagus and stomach, the lower esophageal sphincter (LES). In infants, the LES is thought to strengthen with time as reflux diminishes.
