The side effects of excessive iron supplementation in pregnant women mainly include: 1. Iron toxicity: Excessive iron intake may lead to a large accumulation of iron in the body, causing iron poisoning. Mild cases may present symptoms such as nausea and headache, while severe cases could result in organ failure. 2. Gastrointestinal problems: Excess iron can irritate the gastrointestinal tract, potentially causing indigestion symptoms such as nausea, vomiting, diarrhea, and constipation. 3. Adverse effects on fetal health: Excessive iron intake by the mother may lead to iron toxicity in the fetus, impairing normal fetal development, and in severe cases, may even trigger preterm birth. 4. Increased risk of gestational diabetes: Excess iron may elevate hemoglobin concentration, increasing the likelihood of developing gestational diabetes. Excessive iron supplementation during pregnancy may pose various health risks. Pregnant women should strictly follow medical advice when taking iron supplements and avoid self-administered, unguided supplementation.
