Aspirin, a widely used over-the-counter medication, is known for its effectiveness in relieving pain, reducing inflammation, and preventing blood clots. However, concerns have been raised regarding its potential impact on anaemia, a condition characterised by a deficiency of red blood cells or haemoglobin in the blood. In this article, we explore the evidence surrounding the question: Can aspirin increase the risk of anaemia?
Understanding Anaemia and Aspirin
Anaemia can result from various factors, including nutritional deficiencies, chronic diseases, genetic disorders, and certain medications. While aspirin is not typically considered a direct cause of anaemia, it may indirectly contribute to its development under specific circumstances.
Possible Mechanisms
Aspirin is an antiplatelet agent that inhibits the function of blood platelets, which are involved in blood clotting. While this property is beneficial for individuals at risk of heart attacks or strokes, it can also increase the risk of bleeding. Excessive or prolonged bleeding, in turn, may lead to iron deficiency, a common cause of anaemia.

Furthermore, aspirin's effects on the gastrointestinal tract can also play a role. Prolonged use of aspirin can irritate the stomach lining, potentially leading to ulcers or gastrointestinal bleeding. Chronic blood loss through the digestive system can deplete iron stores and contribute to anaemia.
Scientific Evidence and Recommendations
The relationship between aspirin and anaemia is complex, and studies exploring this specific link are limited. Some research suggests that regular aspirin use, especially at higher doses, may be associated with an increased risk of gastrointestinal bleeding and subsequent anaemia.
However, it is important to note that the majority of individuals who take low-dose aspirin for cardiovascular protection do not develop anaemia. The risk is typically higher in older adults, those with a history of gastrointestinal issues, and those on concurrent medications that may increase bleeding risk.
As with any medication, it is crucial to consult a healthcare professional before initiating aspirin therapy, especially if you have a preexisting condition or take other medications that may interact with aspirin. Healthcare providers can assess your specific situation and provide personalised guidance regarding the benefits and potential risks of aspirin use.
