<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">肛裂是肛管内壁的撕裂或溃疡（<span style="color: black;">病痛</span>） 。肛管是直肠在肛门之前的最后一部分。裂痕可能<span style="color: black;">出现</span>在任何人身上，但在中年人和婴儿中更为<span style="color: black;">平常</span>。它们可能<span style="color: black;">是由于</span>便秘、<span style="color: black;">经过</span>肛门排便和分娩<span style="color: black;">导致</span>的。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">虽然不<span style="color: black;">平常</span>，但憩室病可能会<span style="color: black;">引起</span>血便。这种<span style="color: black;">流血</span>可能不<span style="color: black;">必须</span>治疗，除非它是<span style="color: black;">连续</span>的或严重的。<span style="color: black;">日前</span>尚不清楚是什么<span style="color: black;">原由</span><span style="color: black;">引起</span>了这种<span style="color: black;">状况</span>，但专家认为年龄和遗传可能起<span style="color: black;">功效</span>。</span></p>
