What are the causes of iron deficiency in post menopausal women?

Iron deficiency in postmenopausal women can be caused by several factors, including inadequate dietary intake of iron-rich foods, absorption issues related to gastrointestinal conditions, and blood loss from sources like heavy menstruation or gastrointestinal bleeding. Additionally, hormonal changes after menopause can lead to changes in iron metabolism and increased susceptibility to deficiency. Other contributing factors may include chronic diseases and certain medications that affect iron absorption.
