Vadim Nemkov reveals kidney issues caused cardio problems in Anderson loss

Vadim Nemkov disclosed he suffered kidney problems in 2022 that severely impacted his cardio, leading to his first loss to Corey Anderson. Nemkov experienced rapid fatigue in sparring, unable to complete more than one competitive round. The issue persisted into his fight with Anderson, where he won the first round but ran out of energy in the second. After extensive medical consultation, doctors identified the kidney problem and prescribed medication that resolved the issue. Nemkov has since eliminated all sports supplements from his diet to reduce kidney strain, relying only on basic vitamins, and reports feeling no worse without the supplements.
