They will depend on the underlying cause. You should consult your doctor who will be able to rule out any serious underlying medical condition. If your doctor does diagnose an underlying condition as the cause of your reduced kidney function, then you should follow his or her advice and get the appropriate treatment. However, if your doctor gives you a clean bill of health, you can take certain measures at home to keep your kidneys in good health.
Treatment: The first thing you need to do is to start drinking enough water. Water helps to flush out toxins from the body. Micro-crystalline deposits that may form in your kidneys, the precursor of kidney stones, will also be flushed out if you drink enough water. You can make out whether or not you are drinking enough water by examining the color of your urine. A yellowish stream indicates that you are not drinking enough water and a clear stream tells you that you are. Be careful about consuming too much water. Too much water can upset the electrolytic balance in your body and can even prove to be fatal.
Other foods and herbs that are good for your kidneys are asparagus, cucumber, garlic, papaya, parsley, celery and green beans. Eat plenty of green vegetables and fruits. They have high water content and are packed with nutrients that are good for your system.
You should also exercise regularly, especially if you are diabetic or pre-diabetic. Exercise reduces the risks caused by diseases such as diabetes and hypertension, conditions that have an adverse impact on the health of your kidneys. Other dietary changes will be suggested by your doctor in case you have any kidney diseases or impaired renal function.
