The following is a series of studies performed in Sri Lanka to understand the cause of the high incident rate of Chronic Kidney Disease of uncertain aetiology (CKDu) in the North Central province of the country. There are high fluoride levels in the drinking water in the same area. The latest paper by Jayalal et al. (2020) reported very high fluoride and lead levels in cadaver bone of those who died of CKD. In 2019, Jayalal noted, “The phenomenon of fluoride being known to increase the absorption of lead may be playing a synergistic role in this situation as it had been reported that fluoride concentration in water in the CKDu affected areas is higher.”
