Swallowing pills can be difficult and downright unpleasant. It causes one in three people to gag, vomit, or choke. That may keep people from sticking to their medication routines, which can make them sicker. A study by researchers from the University of Heidelberg in Germany may help people with pill swallowing difficulties. They suggest two techniques that can help people improve their ability to get medicine down. Their report was published in the Annals of Family Medicine.
