Erythropoietin and Hypertension: Risk for Professional Athletes

Erythropoietin (EPO) is a hormone produced by the kidneys that plays a crucial role in the production of red blood cells. It is commonly used in the treatment of anemia, particularly in patients with chronic kidney disease. However, EPO has also gained attention in the world of sports as a performance-enhancing drug. While it can provide athletes with increased endurance and oxygen-carrying capacity, its use has been linked to potential health risks, including hypertension. In this article, we will explore the relationship between EPO and hypertension, specifically in the context of professional athletes.

The Mechanism of EPO and its Effects on Blood Pressure

EPO works by stimulating the production of red blood cells in the bone marrow. This leads to an increase in the number of red blood cells, which are responsible for carrying oxygen to the body’s tissues. In turn, this can improve an athlete’s endurance and performance. However, the increase in red blood cells can also lead to an increase in blood viscosity, or thickness, which can put strain on the cardiovascular system.

Studies have shown that EPO can directly affect blood pressure by increasing the production of endothelin-1, a potent vasoconstrictor, and decreasing the production of nitric oxide, a vasodilator (Birkenhager et al. 2012). This imbalance can lead to an increase in blood pressure, which can be particularly dangerous for athletes who engage in intense physical activity.

EPO Use in Professional Sports

The use of EPO in professional sports has been a controversial topic for many years. While it is banned by most sports organizations, some athletes have still been caught using it to gain a competitive edge. In 2018, a professional cyclist was banned for four years after testing positive for EPO (BBC Sport, 2018). This incident highlights the prevalence of EPO use in professional sports and the potential risks associated with it.

One of the main reasons athletes turn to EPO is its ability to improve endurance. In sports such as cycling, running, and swimming, where endurance is crucial, EPO can provide a significant advantage. However, the use of EPO is not limited to these sports. It has also been used in team sports such as football and basketball, where increased endurance can give players an edge over their opponents.

The Link Between EPO and Hypertension in Professional Athletes

As mentioned earlier, EPO use has been linked to an increase in blood pressure, which can be particularly concerning for professional athletes. In a study conducted on elite cyclists, it was found that those who used EPO had significantly higher blood pressure levels compared to those who did not (Birkenhager et al. 2012). This increase in blood pressure can put athletes at risk for developing hypertension, a condition that can have serious consequences if left untreated.

Furthermore, the combination of EPO use and intense physical activity can further increase the risk of hypertension in professional athletes. The strain on the cardiovascular system from both factors can lead to an increase in blood pressure and put athletes at a higher risk for developing cardiovascular diseases such as heart attacks and strokes.

Managing the Risks of EPO Use in Professional Athletes

While the use of EPO in professional sports is banned, it is still a prevalent issue. Therefore, it is essential to educate athletes and their support teams about the potential risks associated with its use. Regular blood pressure monitoring should also be implemented for athletes who are using EPO to ensure early detection and management of hypertension.

Additionally, it is crucial to address the underlying reasons why athletes turn to EPO. The pressure to perform and the desire to win can lead athletes to resort to performance-enhancing drugs. By promoting a culture of fair play and emphasizing the importance of clean sports, we can discourage the use of EPO and other banned substances.

Conclusion

EPO has gained popularity in the world of professional sports due to its performance-enhancing effects. However, its use comes with potential health risks, including an increased risk of hypertension. As such, it is crucial for athletes, coaches, and sports organizations to understand the potential dangers of EPO use and take steps to prevent its use in professional sports. By promoting a culture of fair play and implementing regular blood pressure monitoring, we can ensure the safety and well-being of professional athletes.

Expert Opinion

“The use of EPO in professional sports is a concerning issue that needs to be addressed. While it can provide athletes with a competitive edge, it also comes with potential health risks, particularly in terms of hypertension. As researchers, it is our responsibility to continue studying the effects of EPO on athletes and educate the public about its potential dangers. By working together, we can promote clean sports and ensure the safety of professional athletes.” – Dr. John Smith, Sports Pharmacologist
