It can affect any part of the gastrointestinal tract, from the mouth to the anus, but most commonly involves the small intestine and colon. Crohn\u2019s disease often follows a relapsing and remitting course, meaning symptoms may flare up and then improve with treatment.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Crohn\u2019s Disease?<\/h2>\n\n\n\n<p>Crohn\u2019s disease is an <strong>immune-mediated condition<\/strong> in which the body\u2019s immune system mistakenly attacks the digestive tract, leading to inflammation.
