Vadim Nemkov reveals kidney issues caused cardio problems in Corey Anderson loss

Vadim Nemkov disclosed that kidney problems severely impacted his performance in his first fight against Corey Anderson in 2022. He experienced dramatic cardio decline after the first round in both sparring and competition, describing it as running out of fuel. After extensive medical testing, doctors identified kidney issues related to extreme weight cuts as the root cause. Nemkov found an appropriate legal medication that resolved the problem and has since eliminated all sports supplements from his regimen. He confirmed the kidney issues were the direct reason for his poor stamina in the Anderson bout.
