如题所述

Answer 1

痔疮的发生通常与多种因素有关，常见的包括不良饮食习惯、不良排便习惯、感染因素、职业因素、遗传因素、疾病因素等，可导致肛周组织回缩作用减弱或局部静脉回流受阻，进而引起痔疮。建议日常生活中注意改善这些诱发因素，若痔疮症状严重，可就医治疗。
1、饮食因素：经常食用海鲜、辣椒、烧烤等辛辣刺激性食物，以及长期饮酒等，可导致肛门局部充血、水肿，易引起痔疮发生；
2、不良排便习惯：排便次数过多、时间过长、过于用力，以及经常腹泻或便秘等，也是引发痔疮的常见因素。如经常便秘会因为大便干结而压迫直肠，静脉血液回流不畅，长期如此会出现静脉曲张、充血，从而导致痔疮；
3、感染因素：肛门周围发生细菌、真菌、寄生虫感染可引起静脉曲张或血管内膜炎，使静脉失去弹性而扩张，可增加痔疮的发生风险；
4、职业因素：如司机、办公室职员、电焊工等需要久坐、久蹲的人群，患痔疮的风险性较高，主要是因为直肠位于人体下部，长期久坐、久蹲会使静脉血液回流受阻，造成患痔疮的风险增加；
5、遗传因素：研究表明，痔疮发病存在一定的家族遗传倾向，若父母患有痔疮，其子女患痔疮的可能性则相对较高；
6、疾病因素：如前列腺肥大、盆腔肿瘤以及直肠、肛管的慢性炎症等，可导致局部静脉丛扩张、血液瘀滞，使直肠静脉回流受阻，从而引起痔疮；
7、其他原因：妊娠期以及分娩时由于子宫增大、腹腔内压力增加，导致局部血液回流不畅，易出现痔疮。另外，营养不良可使局部组织痿软无力，部分患者易发生痔疮。

Words not said, eyes closed forever.

We all kneel on the ruins, kneeling in front of the unknown youth young, tears and the rain dripped down flowing downwards. After a few minutes, we slowly raised his right hand and offered a standard military salute to him.
