heartburn

Millions of people take proton pump inhibitors. But the drugs can increase the risk of infections, bone fractures and kidney problems. And trying to stop the drugs can make symptoms much worse.

Medications for heartburn called proton pump inhibitors are linked to a higher risk for chronic kidney disease, according to a study. It's the latest in a growing list of worries with these drugs.

The drugs are proton-pump inhibitors, including Prilosec, Nexium and Prevacid. But the study doesn't show cause and effect. Other factors — diet, drink or tobacco — may play a role.
