What are the health risks of using performance-enhancing drugs in humans?

Some athletes prefer using such stimulants; prolonged use can harm the body and trigger various diseases. What are the health risks associated with stimulant abuse?

Health Risks of Stimulant Abuse

Stimulants pose significant health hazards. In male athletes, their use may lead to erectile dysfunction, testicular atrophy, reduced sperm production, or even azoospermia—ultimately impairing fertility. Additional adverse effects include personality changes, renal dysfunction, gynecomastia (breast enlargement), and premature baldness. Female athletes who chronically misuse these substances may experience hair loss, sexual dysfunction, menstrual irregularities, amenorrhea, and infertility. Moreover, they may develop irreversible virilizing features—including deepening of the voice, increased muscle mass, hirsutism (excessive hair growth), and facial hair—even after discontinuation. For both male and female athletes, the most severe risks include hypertension, coronary artery disease, myocardial infarction, cerebral hemorrhage, as well as hepatocellular carcinoma and renal cell carcinoma.

Stimulants act by promoting the release of neurotransmitters, often resulting in heightened arousal, enhanced self-confidence, agitation, or even psychotic symptoms. They augment dopamine activity within the mesolimbic cortical reward circuitry, producing euphoria. Additionally, stimulant use commonly improves mental alertness and gradually increases physical endurance.

Long-term, high-dose stimulant use frequently leads to abuse and acute or chronic toxicity. Withdrawal may produce characteristic withdrawal symptoms. Therefore, once stimulant misuse is clinically confirmed, immediate cessation and comprehensive detoxification therapy should be initiated. Ensuring adequate sleep duration is also essential.
