Taking low-dose aspirin was associated with an increased incidence of anemia, as well as a decrease in ferritin or blood iron levels in otherwise healthy elderly people. This is according to research published in the journal “Annals of Internal Medicine”.

About half of the elderly in the United States of America have reported preventive aspirin use. One of the complications of its use is the increased risk of severe bleeding, especially gastrointestinal.

Researchers from Melbourne’s Monash University analyzed a randomized controlled trial of aspirin in 19,114 people aged 70 and over.

Participants were assigned to take 100 mg of aspirin daily or a placebo.

The study found that the risk of developing anemia was 23.5% among those taking low-dose aspirin, and it was accompanied by a small decrease in mean hemoglobin and a greater decrease in ferritin concentration.
