Copper toxicity toxicity. Some of the effects of aging may be associated with excess copper. One manifestation of copper toxicity, cirrhosis of the liver in children (Indian childhood cirrhosis), has been linked to boiling milk in copper cookware. The Merck Manual states recent studies suggest that a genetic defect is associated with this particular cirrhosis. An inherited condition called Wilson's disease causes the body to retain copper, since it is not excreted by the liver into the bile. This disease, if untreated, can lead to brain and liver damage, and bis-choline tetrathiomolybdate is under investigation as a therapy against Wilson's disease. Elevated
Copper in health significant percentage of the population are lower than recommended levels. On the other hand, the U.S. National Research Council concluded in its report Copper in Drinking Water that there is concern for copper toxicity in susceptible populations and recommended that additional research be conducted to identify and characterize copper-sensitive populations. Excess copper intake causes stomach upset, nausea, and diarrhea and can lead to tissue injury and disease. The oxidation potential of copper may be responsible for some of its toxicity in excess ingestion cases. At high concentrations copper is known to produce oxidative damage to biological systems, including peroxidation of
