Smoking tobacco introduces a variety of harmful chemicals into your body. The chemicals enter the bloodstream and are processed through the body. Since kidneys filter toxins out of the blood, the kidneys are regularly exposed to concentrated amounts of these harmful chemicals.

Quitting smoking is an important step in preventing kidney and other cancers. The sooner smoking is stopped, the sooner the body can start to heal. Talk to your doctor about the options available to help you successfully quit.

Chemical exposure can occur in many different jobs. If possible, try to find work in a different environment. If it is unavoidable, take steps to protect yourself from exposure. Check with the National Institute for Occupational Safety and Health or the Environmental Protection Agency about any available protective guidelines.

Regular exercise will help you meet your weight loss goals. If you need to lose weight, talk to your doctor or a registered dietitian who can help you do so slowly and safely
