Can Acid Reflux Cause Iron Deficiency?

Yes, acid reflux (gastroesophageal reflux disease or GERD) can potentially contribute to iron deficiency anemia, although it’s not the primary cause of iron deficiency. The connection between acid reflux and iron deficiency is typically related to chronic gastrointestinal bleeding or inflammation associated with GERD. Here’s how this can happen:

  • Esophagitis: Inflammation or irritation of the esophagus due to chronic acid reflux can lead to small erosions or ulcers in the lining of the esophagus. These erosions may bleed over time, although the bleeding is often subtle and not visibly noticeable. This chronic, low-grade bleeding can result in iron loss, contributing to iron deficiency.
  • Bleeding in the stomach and duodenum: In some cases, stomach acid from reflux may lead to irritation and ulcers in the stomach or duodenum (the first part of the small intestine). These ulcers can also cause small amounts of bleeding, leading to iron deficiency.

It’s important to recognize that not everyone with GERD will develop iron deficiency anemia. The risk factors for developing iron deficiency anemia due to acid reflux include the severity and duration of the condition, as well as individual susceptibility.

If you suspect that your acid reflux is contributing to iron deficiency, it is crucial to seek medical evaluation and treatment. A healthcare provider can perform blood tests to assess your iron levels and may recommend endoscopic procedures to examine the esophagus and gastrointestinal tract. Treatment options may include managing GERD through lifestyle modifications, dietary changes, and medication, as well as iron supplementation to address iron deficiency anemia if necessary.
