What health issue may arise from long-term consumption of water with high fluoride levels?

Long-term consumption of water with high fluoride levels can lead to a condition known as skeletal fluorosis, which is characterized by the gradual accumulation of fluoride in the bones. This can result in brittle bones, making them more susceptible to fractures. Fluoride in excessive amounts disrupts the normal process of bone remodeling, potentially leading to pain, stiffness, and a reduction in bone strength over time.

While other health effects can arise from fluoruoride exposure, the primary concern with high levels in drinking water is related specifically to bone health. Conditions like tooth decay may seem relevant, but they are more often associated with low fluoride levels. Similarly, kidney failure and heart disease, while significant health concerns, are not directly linked to fluoride exposure in the same way. This highlights the importance of monitoring fluoride levels in drinking water to prevent such long-term skeletal issues.
