Short-term side effects

Fluid retention and increased blood volume

Erythropoietin (EPO) is a hormone that regulates the production of red blood cells in the body. When athletes use EPO, it stimulates the production of red blood cells, which can lead to an increase in blood volume. This increase in blood volume can cause fluid retention, resulting in swelling of the hands, feet, and other parts of the body.

Fluid retention can be a significant concern for athletes who use EPO, as it can impact their performance and comfort during training and competition. Additionally, the increased blood volume can cause a decrease in blood pressure, which can lead to dizziness, fainting, and other adverse effects.

Thrombotic events and cardiovascular risks

Another short-term side effect of EPO use in sports is an increased risk of thrombotic events, such as deep vein thrombosis (DVT) and pulmonary embolism (PE). EPO can cause an increase in platelet production, which can lead to blood clots forming in the veins.

DVT is a serious condition that can cause swelling, pain, and inflammation in the affected limb. If left untreated, it can lead to PE, which can be life-threatening.

Furthermore, EPO use has been associated with an increased risk of cardiovascular events, such as heart attack and stroke. This is because EPO can cause an increase in blood viscosity, which can lead to an increased risk of blood clots forming in the arteries.

It is important for athletes to be aware of these short-term side effects of EPO use and to take steps to mitigate their risk. This may include regular monitoring of blood pressure and blood viscosity, as well as regular physical activity to promote blood flow and reduce the risk of blood clots forming.

Long-term side effects

Erythropoietin (EPO) is a hormone that stimulates the production of red blood cells in the body. While its use in sports has been associated with increased endurance and performance, there are also several long-term side effects that have been linked to its use.

  • Impaired kidney function and nephrotoxicity: The use of EPO has been associated with a decrease in kidney function and an increased risk of kidney damage. This is because EPO can cause the body to produce more red blood cells than it needs, which can lead to the accumulation of excessive levels of red blood cell breakdown products in the kidneys. This can cause damage to the delicate filtering units of the kidneys, leading to impaired kidney function and potentially irreversible damage.
  • Anemia and bone marrow suppression: The use of EPO can also lead to anemia, a condition in which the body does not have enough red blood cells to carry oxygen to the tissues. This is because EPO can cause the body to produce more red blood cells than it needs, which can then be destroyed by the body’s immune system. This can lead to a decrease in the number of red blood cells in the body, resulting in anemia. Additionally, EPO can also suppress the production of white blood cells in the bone marrow, which can lead to bone marrow suppression.

It is important to note that these long-term side effects can occur even in individuals who use EPO for medical reasons, such as those undergoing chemotherapy or kidney dialysis. Therefore, it is essential to carefully weigh the benefits and risks of EPO use before deciding to use it for any purpose.
