</div></div><div class="section-body" id="section-1"><p>Your kidneys' main job is to remove toxins and extra fluid from your blood and regulate some aspects of your body's chemical balance. If waste products build up in your body, it can be dangerous and even cause death.</p><p>Kidney dialysis (peritoneal dialysis and other types of dialysis) does some of the job of the kidneys when they stop working well. This process:</p><ul><li>Removes extra salt, water, and waste products so they do not build up in your body</li><li>Keeps safe levels of minerals and vitamins in your body</li><li>Helps control blood pressure</li><li>Helps produce red blood cells</li></ul><p><strong>WHAT IS PERITONEAL DIALYSIS?</strong></p><p>Peritoneal dialysis (PD) removes waste and extra fluid through the blood vessels that line the walls of your abdomen. A membrane called the peritoneum covers the walls of your abdomen.</p><p>PD involves putting a soft, hollow tube (catheter) into your abdominal cavity and filling it with a cleansing fluid (dialysis solution). The solution contains a type of sugar that draws out waste and extra fluid. The waste and fluid passes from your blood vessels through the peritoneum and into the solution. After a set amount of time, the solution and waste is drained and thrown away.</p><p>The process of filling and draining your abdomen is called an exchange. The length of time the cleansing fluid remains in your body is called the dwell time. The number of exchanges and amount of dwell time depends on the method of PD you use and other factors.</p><p>Your doctor will perform surgery to place the catheter in your abdomen where it will stay. It is most often near your belly button.</p><p>PD may be a good option if you want more independence and are able to learn to treat yourself. You will have a lot to learn and need to be responsible for your care. You and your caregivers must learn how to:</p><ul><li>Perform PD as prescribed</li><li>Use the equipment</li><li>Buy and keep track of supplies</li><li>Prevent infection</li></ul><p>With PD, it is important not to skip exchanges. Doing so can be dangerous to your health.</p><p>Some people feel more comfortable having a health care provider handle their treatment. You and your provider can decide what is best for you.</p><p><strong>TYPES OF PERITONEAL DIALYSIS</strong></p><p>PD gives you more flexibility because you do not have to go to a dialysis center. You can have treatments:</p><ul><li>At home</li><li>At work</li><li>While traveling</li></ul><p>There are 2 types of PD:</p><ul><li><strong>Continuous ambulatory peritoneal dialysis (CAPD)</strong>. For this method, you fill your abdomen with fluid, then go about your daily routine until it is time to drain the fluid. You are not hooked up to anything during the dwell period, and you do not need a machine. You use gravity to drain the fluid. The dwell time is usually about 4 to 6 hours, and you will need 3 to 4 exchanges each day. You will have a longer dwell time at night while you sleep.</li><li><strong>Continuous cycling peritoneal dialysis (CCPD)</strong>. With CCPD, you are connected to a machine that cycles through 3 to 5 exchanges at night while you sleep. You must be attached to the machine for 10 to 12 hours during this time. In the morning, you begin an exchange with a dwell time that lasts all day long. This allows you more time during the day without having to do exchanges.</li></ul><p>The method you use depends on your:</p><ul><li>Preferences</li><li>Lifestyle</li><li>Medical condition</li></ul><p>You can also use some combination of the two methods. Your provider will help you find the method that works best for you.</p><p>Your provider will monitor you to make sure the exchanges are removing enough waste products. You will also be tested to see how much sugar your body absorbs from the cleansing fluid. Depending on the results, you may need to make certain adjustments:</p><ul><li>To do more exchanges per day</li><li>To use more cleansing fluid at each exchange</li><li>To decrease the dwell time so you absorb less sugar</li></ul><p><strong>WHEN TO START DIALYSIS</strong></p><p>Kidney failure is the last stage of long-term (chronic) kidney disease. This is when your kidneys can no longer support your body's needs. Your doctor will discuss dialysis with you before you need it. In most cases, you will go on dialysis when you have only 10% to 15% of your kidney function left.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Risks</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
