Your heartburn meds

People who took proton pump inhibitors for heartburn and acid reflux were more likely to develop kidney disease than people who took other forms of antacids such as histamine-2 receptor antagonists, a study shows. Exactly how these drugs may increase this risk is not fully understood, says the National Kidney Foundation, but the group notes that the drugs can cause an allergic reaction that leads to swelling inside your kidney (called acute interstitial nephritis). If caught early, the condition can be treated.
