Some heartburn treatments depress body iron levels, study finds

New research has found an association between some popular heartburn treatments and iron deficiency.

Heartburn is a symptom of gastroesophageal reflux, which is caused by rising into the throat. This condition affects more than two million Australians and is often treated with medications that suppress acid secretion.

The collaboration between academics at the Universities of Melbourne, Utrecht and Maastricht was the first population-based study to find that (PPIs), a class of acid suppressants that are widely prescribed for heartburn, disease (GERD) and peptic ulcers, are associated with .

Iron deficiency is the most common cause of anaemia, which affects about 2.2 billion people globally.

Dr. An Duy Tran, a Senior Research Fellow at the Melbourne School of Population and Global Health, said PPIs could lead to iron malabsorption because acid was needed for iron absorption.

"Whether or not PPI use led to iron deficiency has long been inconclusive," he said.

The study, published in published in Journal of Internal Medicine, used data from more than 50 000 patients and showed that continuous PPI use for more than one year increased the risk of iron deficiency. People using one tablet of 20 mg PPI or more daily had a higher risk of iron deficiency compared with people using less than one tablet daily.

"Many doctors tend to overprescribe proton pump inhibitors and do not rigorously weigh their benefits against their harms," he said.

"It is important to increase awareness about the harmful effects.

"To my knowledge current guidelines do not recommend regular iron monitoring during PPI administration. It seems that many doctors are not aware of the time and dose-response in patients using PPIs," Dr. Tran said.

Other recent studies have shown that long-term use of PPIs is associated with gastric cancer and enteric infection, and pneumonia.

More than 19 million prescriptions for proton pump inhibitors were written in Australia during 2013-2014.

for a country that believes in evolution and survival of the fittest we sure do jump through hoops to not allow people to make their own stupid decisions. Rather than informing people that something may be dangerous ( like cigarettes and alcohol ) we ban everything that may or may not be harmful, and tightly regulate the rest. We punish 99% of the population for the stupid choices of the 1%. There are so many things out there that have legitimate medical uses, but because a few teenagers abused them the rest of us have to do without.
