Abstract
The case is presented of 77-year-old woman with a ten-year history of weight loss, dyspepsia, and gastric ulcer resistant to medical management. Within two weeks after she began using a reverse osmosis (RO) unit on her municipal fluoridated (0.85–1.0 ppm F) drinking water source and, without further medication, the patient gained almost full recovery. In 2007, at age 87, while still continuing to use the RO water for drinking and cooking, she remained well and described the improvement in her health as being “just a miracle.” Fluoride in drinking water, at the levels commonly used in water fluoridation, may produce chronic ill health with dyspepsia.
