The procedure helps to restore the good bacteria that have been killed off or limited by the use of antibiotics. Restoring this balance in the colon makes it easier to fight infection.</p></div><section><div class="section"><div class="section-header"><div class="section-title"><h2>Description</h2></div><div class="section-button"><button type="submit" aria-controls="section-1" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">

</div></div><div class="section-body" id="section-1"><p>FMT involves collecting stool from a healthy donor. Your health care provider will ask you to identify a donor. Most people choose a family member or close friend. The donor must not have used antibiotics for the previous 2 to 3 days. They will be screened for any infections in the blood or stool.</p><p>Once collected, the donor's stool is mixed with saline water and filtered. The stool mixture is then transferred into your digestive tract (colon) through a tube that goes through a colonoscope (a thin, flexible tube with a small camera). The good bacteria can also be introduced into the body by way of a tube that goes into the stomach through the mouth. Another method is to swallow a capsule that contains freeze-dried donor stool.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Why the Procedure is Performed</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">

These bacteria that live in your intestines are important for your health, and grow in a balanced manner.</p><p>One of these bacteria is called <em>Clostridioides difficile</em> (<em>C difficile)</em>. In small amounts, it does not cause problems.</p><ul><li>However, if a person receives repeated or high doses of antibiotics for an infection elsewhere in the body, most of the normal bacteria in the intestine may be wiped out. Bacteria grow and release a toxin.</li><li>The result may be that there is too much of the <em>C difficile</em>.</li><li>This toxin causes the lining of large intestine to become swollen and inflamed, causing fever, diarrhea, and bleeding. </li></ul><p>Certain other antibiotics can sometimes bring the <em>C difficile</em> bacteria under control. If these do not succeed, FMT is used to replace some of the <em>C difficile</em> with "good" bacteria and restore the balance.</p><p>FMT also may be used to treat conditions such as:</p><ul><li><a test="test" href="./000246.htm">Irritable bowel syndrome</a></li><li><a test="test" href="./000249.htm">Crohn disease</a></li><li>Constipation</li><li><a test="test" href="./000250.htm">Ulcerative colitis</a></li></ul><p>Treatment of conditions other than recurrent <em>C difficile</em> colitis are considered experimental at present and are not widely used or known to be effective.</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-3" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
