Everything you need to know about Iron after bariatric surgery

Written by Bryee Shepard, MS, RD and medically reviewed by Dr. Stephen Boyce, MD

Iron, an essential mineral in the human body, plays many vital roles necessary to a healthy life. Let’s learn more about iron and its special importance for those who are undergoing or have undergone bariatric surgery.

The role of Iron in the body

Because of its various functions, humans cannot live without an adequate iron intake. Some of iron’s important tasks in the body include:

Main functions of iron in the body

Iron is a trace mineral that is taken in through the diet, utilized, and stored. Although a crucial mineral to ensure you’re getting enough of, it is possible to have too much of a good thing. The body requires a narrow amount of iron, and too little or too much can cause dysfunction.

Too much iron, also known as iron overload or iron toxicity, can cause:

  • Organ damage
  • Nervous system damage
  • Plaque build up in the arteries
  • Cancer
  • Diabetes
Risks of too much iron

However, more common than iron overload is iron deficiency. This occurs when the individual either doesn’t consume enough iron or loses too much iron in various ways. More on this in a bit!

Eating a diet full of iron-rich foods is important to keep iron levels where they should be. Foods rich in iron include:

  • Meats
  • Chicken
  • Pork
  • Fish
  • Tofu
  • Legumes
  • Whole grains
  • Dark leafy greens
  • Nuts and seeds such as pistachios and sesame seeds
  • Fruits such as strawberries and kiwi
Foods rich in iron

However, for those that have undergone bariatric surgery, eating foods with a high iron content usually isn’t enough to meet iron needs. A multivitamin including iron or a stand-alone iron supplement, if needed, is also a great way to guarantee you are meeting your needs for iron.

What are the ASMBS guidelines on Iron after bariatric surgery?

With its vast research database and expertise, the American Society for Metabolic and Bariatric Surgery (ASMBS) sets the standard for the dietary needs of individuals that have undergone or will be undergoing bariatric surgery.

Because iron is so tightly regulated in the body, there are more precise recommendations based on the individual and their circumstance:

  • Low-risk men with no history of anemia should supplement with 18mg iron daily in a multivitamin
  • Menstruating women and those patients that have undergone gastric bypass, gastric sleeve, or biliopancreatic diversion with duodenal switch should supplement with 45-60mg of iron daily

Signs, symptoms, and complications that can arise from becoming deficient

Anemia affects one-quarter of the world’s population, with iron deficiency being the main cause. Iron deficiency can lead to cells not being able to store and transport oxygen around the body. That is, the oxygen from the air we breathe cannot be used effectively in the body.

This decrease in oxygen transport can lead to an array of symptoms such as:

Anemia is common worldwide resulting from iron deficiency

Beyond the symptoms, having iron deficiency puts you more at risk for:

  • Infections
  • Heart problems
  • Depression
  • Pregnancy complications
  • Delayed development in children
Risks associated with iron deficiency

If left untreated, long-term iron deficiency can lead to death from heart or lung dysfunction.

This might beg the question: Are bariatric patients at a higher risk for iron deficiency? The answer is a resounding, YES. It is thought to be caused by a variety of factors including a decrease in mineral absorption from structural changes to the gastrointestinal tract, as well as less gastric acid produced, an important component of iron absorption in the body.

Iron deficiency is also more common in the bariatric surgery population because they may have more difficulty tolerating iron-rich foods, such as red meats. Some women may find that their menstrual cycles regulate, and therefore more blood is lost on a regular basis. Not to mention that up to 45% of obese people have some form of iron deficiency before even stepping foot in a surgeon’s office.

As mentioned above, blood loss is a leading cause of iron deficiency. Here is a list of the main causes of iron loss in the body:

For this reason, it is important to ensure you are getting the right amount of iron for your needs. Your doctor can also check your iron levels with simple blood work to help avoid and/or treat iron deficiency. Eating a diet consisting of iron-rich foods and taking a supplement can help reduce your chances of becoming deficient in iron.
