According to the Nevada State Athletic Commission, American Top Team fighter Thiago Alves tested positive for the banned substance Spironolactone. Alves is coming off of a victory over Tony DeSouza at UFC 66. The Brazilian fighter did not test positive for steroids or any other performance enhancing drugs.

A prescribed drug, Spironolactone is a diuretic that is used mainly to lose weight and can mask steroids. The NSAC banned substance causes a person’s kidneys to remove excess sodium and water from their body. The use of Spironolactone is considered a dangerous way for someone to lose excess weight and can cause dehydration. The drug has negative side effects that include ataxia, impotence, an increased risk of bleeding from the stomach and many other symptoms.

The NSAC has yet to officially suspend or fine Thiago Alves.
