Preventing and Treating Kidney Disease
Click to enlarge

Chances are you pay far more attention to your heart or brain than your kidneys. But if your kidneys don’t function well, your heart and brain—as well as every other organ in your body—will suffer as well.

Various types of kidney problems may develop because of increasing age, inherited medical conditions, infections or injury, or underlying health problems such as hypertension and diabetes. In this report, you’ll learn more about how your kidneys work and what can go wrong. You’ll learn about what factors put you at risk for various problems, especially for chronic kidney disease, and what steps you can take to keep your kidneys functioning as well as possible. You’ll also learn more about the latest treatments for kidney disease, how to cope with emotional and logistical challenges, and what resources are available that may help. Most important, you’ll get information you need to become an informed and active participant in your care. 48 pages. (updated: 2005)

Here's an Excerpt from this Special Health Report

Each bean-shaped kidney measures about four to five inches long, about the size of an adult fist. Yet in spite of their diminutive size, your kidneys are biological powerhouses. Although they constitute less than 1% of your body weight, at any given time they receive about 20% of your blood. Your kidneys are busy monitoring, cleansing, and recycling about 50 gallons of blood every 24 hours. That means all 10 pints of blood in the average person’s body are processed about 40 times a day.

Your kidneys perform two main functions: They eliminate wastes, and they help regulate your body’s internal environment by keeping blood levels of certain hormones, electrolytes, and nutrients in balance.

When both of your kidneys are healthy, you have 100% renal function. Fortunately the kidneys are amazingly resilient organs and initially able to handle more blood processing and waste removal than your body needs, so a small decline in renal function does not affect your health. This built-in overcapacity also explains why people can function with one healthy kidney, either because they are born that way or because they donate a kidney to someone else.

Specific kidney problems may develop after an infection or injury, or because of some underlying health problem such as diabetes and hypertension. Some kidney problems are acute, meaning that they occur suddenly, usually cause noticeable symptoms, and may be reversible. But the more common types of kidney problems are chronic: They take years (even decades) to develop, may not produce symptoms at first, and require long-term treatment.
