Short Answer:

Certain groups of people are at higher risk of iron deficiency due to increased iron needs or lower intake. Women of childbearing age, especially those with heavy menstrual bleeding, are prone to deficiency. Pregnant and breastfeeding women also need more iron to support fetal growth and milk production.

Other high-risk groups include infants and young children, adolescents during rapid growth, vegetarians and vegans who rely mainly on non-heme iron, and individuals with digestive disorders that impair absorption. Identifying these groups helps in planning iron-rich diets and preventing anemia.

Detailed Explanation:

Women of Childbearing Age

Women who menstruate are at higher risk of iron deficiency because of regular blood loss, which reduces iron stores. Heavy or prolonged periods increase the risk further. Iron is essential for replacing lost hemoglobin, and inadequate intake can quickly lead to iron deficiency anemia, causing fatigue, weakness, pale skin, and reduced immunity.

Pregnant and Breastfeeding Women
Pregnancy significantly increases iron requirements to support fetal growth, placenta development, and increased blood volume. Breastfeeding women also need more iron to enrich breast milk for the infant. Without sufficient dietary iron or supplements, these women are at high risk of deficiency, which can affect both mother and child’s health.

Infants, Children, and Adolescents
Infants and young children require iron for rapid growth and brain development. Adolescents experience rapid growth and hormonal changes that increase iron needs. Inadequate intake during these stages can lead to delayed development, fatigue, and cognitive challenges. Iron-fortified formulas or foods are important for infants, and balanced diets for children and teens help prevent deficiencies.

Vegetarians and Vegans
Vegetarians and vegans rely mainly on plant-based iron (non-heme), which is absorbed less efficiently than heme iron from animal sources. Without careful meal planning, combining non-heme iron with vitamin C-rich foods, and avoiding inhibitors like tea or excessive calcium at meals, these individuals are more prone to iron deficiency.

Individuals with Digestive Disorders or Blood Loss
People with celiac disease, Crohn’s disease, ulcerative colitis, or other gastrointestinal disorders may have impaired iron absorption, putting them at risk. Chronic blood loss from gastrointestinal bleeding, ulcers, or injury also reduces iron stores. Certain medications, like proton pump inhibitors, can reduce stomach acid, further impairing absorption.

Other Risk Factors
Athletes, especially endurance athletes, may have increased iron needs due to higher energy expenditure and minor blood loss from exercise. Older adults may also face reduced iron absorption or intake due to dietary limitations. Awareness of these risk factors is important for prevention and early intervention.

Prevention Strategies
High-risk individuals should consume iron-rich foods like red meat, poultry, fish, legumes, leafy greens, nuts, seeds, and fortified cereals. Pairing non-heme iron sources with vitamin C-rich foods improves absorption. In some cases, iron supplements may be recommended under medical supervision. Regular monitoring of hemoglobin and iron status helps prevent anemia.

Conclusion

Women of childbearing age, pregnant and breastfeeding women, infants, children, adolescents, vegetarians, vegans, and people with digestive disorders or chronic blood loss are at higher risk of iron deficiency. Recognizing these groups and ensuring adequate iron intake through diet, fortified foods, or supplements helps maintain hemoglobin levels, prevent anemia, support energy, immunity, and overall health.
