A recent study published in JAMA Network Open reveals that approximately 29% of U.S. adults experience either absolute or functional iron deficiencies.

Nearly one in three Americans may have an undiagnosed iron deficiency, which is often overlooked despite its significant impact on public health.

The research underscores the need for heightened awareness among both healthcare providers and patients regarding the prevalence of iron deficiency.

Experts recommend focusing screening efforts on individuals exhibiting symptoms of iron deficiency, such as fatigue, and those at higher risk, including pregnant women.

Pregnant women are particularly susceptible, requiring an additional 1,000 to 1,500 milligrams of iron, often going undetected until later stages of pregnancy.

Leo Buckley, a study author, highlights that iron deficiency can significantly diminish quality of life and often remains undetected due to the lack of routine iron level checks in bloodwork.

Iron deficiency is linked to various health issues beyond anemia, including fatigue, cognitive difficulties, and heart problems.

Symptoms of iron deficiency can manifest as extreme fatigue, weakness, headaches, and dizziness, stemming from reduced oxygen supply to the brain.

Dietary choices, particularly among vegetarians and vegans, can contribute to iron deficiency, with red meat identified as the best source of iron.

Postpartum women and those experiencing heavy menstrual bleeding are also at increased risk for iron depletion.

Iron deficiency can indicate serious underlying health issues, such as gastrointestinal bleeding or colorectal cancer.

Treatment for low iron levels may involve dietary changes and iron supplements, which should be taken under medical supervision to avoid toxicity.
