Eating Clay Side Effects

Eating clay, also known as geophagy, can lead to several harmful side effects and health risks.

  • Parasite and bacterial infections: Clay and soil may contain eggs of parasites (such as worms) and bacteria like Clostridium tetani, increasing the risk of infections and diseases, especially in children[1][3].
  • Intestinal issues: There is a risk of intestinal blockage (occlusion) or even perforation from consuming clay, which can, in severe cases, lead to death[1][7].
  • Heavy metal toxicity: Clay often contains toxic substances such as lead, aluminum, nickel, and chromium. Regular ingestion can lead to dangerous accumulations of these metals in the body, potentially causing liver, kidney, heart damage, and increasing cancer risk[2][4][5][6].
  • Anemia and mineral deficiencies: Eating clay can bind important nutrients in the gut, such as iron and zinc, impairing absorption and leading to mineral deficiencies and anemia. These deficiencies can result in retarded growth, delayed sexual maturity, and enlargement of the spleen and liver, particularly in children and pregnant women[1][2][7].
  • Pregnancy complications: Pregnant women who consume clay are at increased risk for anemia, hypertension, exposure to toxic metals, birth defects, preterm birth, and low birth weight in newborns[2][5][6][7].
  • Dental damage and constipation: The practice can lead to tooth damage and constipation, with occasional reports of intestinal obstruction[1][7].
  • Potential interference with medications and nutrients: Consumed clay may also bind to pharmaceuticals and nutrients in the digestive tract, reducing their effectiveness[4].
