Iron and Constipation

Aside from its function of oxygenation, iron is necessary through the process of energy metabolism, DNA synthesis, and the functioning of many enzymes. Feeding daily with a total of sufficient iron is necessary for a good state of health and the prevention of anemia.

Iron is derived from both animals and plants as shown below. In meat heme iron is the major iron form and it is rapidly absorbed. However, the other type of iron known as non-heme iron which is present in bean-based foods, lentils, fortified cereals, etc absorbed slowly.

It is the RDA in which the amount has to do with factors such as age and gender as well as stage in one’s life. For example, 8 mg per day is necessary for adult men; and post-menopausal women who lack menstrual blood loss; and 18 mg daily is required for premenopausal females.

At this point when the relation between iron and constipation arises one must diverge between correlation and causation. However, constipation may be due to various things such as dehydration, inadequate dietary fiber, and a few underlying diseases.

One of the hypot- theses might be that iron which is unabsorbed in the gastrointestinal tract might therefore have the ability to act as a stool hardener thus causing constipation. Nevertheless, the reaction to iron differs and the dosage of iron forms of iron( heme or non-heme) and the overall dietary routine may all be part of this analysis.


In conclusion constipation and iron serve as the perpetual maze and a connector in their complex connection. There can be no doubt that iron is a very important nutrient that has wide-ranging health consequences.
