Sodium-containing medications and laxative use among older primary care patients requiring sodium restriction: findings from the LAXAP study

Key takeaways

The LAXAP study counted how often older primary care patients who are told to cut back on salt are given medicines and laxatives that contain sodium anyway. This matters because hidden sodium in pills can undo a low salt diet, which many people with kidney disease are asked to follow. It is an observational count, so it shows how common the problem is, not what happens to kidneys as a result. Detailed numbers were not posted with this record.
