Diminished kidney function is usually the result of another health condition, most notably high blood pressure or diabetes. The kidneys are responsible for filtering waste and fluids. When they are operating below their normal capacity, you can experience a number of side effects and complications. While certain treatments can help slow progression and improve function, it is usually not possible to restore kidney function completely. The Mayo Clinic offers several suggestions.

Manage underlying causes. Properly addressing the medical problems that are contributing to your kidney disease is the most important part of treatment. Doing all you can to treat these conditions can mitigate the decline of your kidneys’ ability to do their job. Take all medications as directed. Keep up with your doctor’s appointments and any necessary testing.

Follow all of your doctor’s instructions regarding medications to address your kidney disease specifically and his advice about self-care measures and lifestyle changes. You might require certain medications to manage your condition and prevent complications.

Talk to your doctor if you notice new symptoms or experience anything that concerns you. Poor kidney function can cause a host of complications. The earlier you address them, the better. This can minimize the impact these problems have on your kidney function.

Eat a low-protein diet. The structure of protein is more complex than fats and carbohydrates. It takes longer to break down, and if you are experiencing kidney problems, it is even more taxing. Protein will have to be a small percentage of your daily caloric intake; your doctor will tell you how much is appropriate for your condition.

Avoid substances that are toxic to your kidneys. One of the most common culprits is over-the-counter NSAIDs (nonsteroidal anti-inflammatory drugs) such as aspirin, Motrin, Aleve and Advil. Do not drink alcohol or use other types of drugs. Your doctor is a good source of information on this matter.
