设计师Mychael Knight（“Project Runway”决赛入围者）的死因仍然是一个谜。这位39岁的时尚明星最近几个月一直公开谈论他与肠易激综合征和极度减肥的斗争，让许多人怀疑这种疾病是否可能在他的死亡中起作用。医生认为这不太可能.
Knight’s的密友，Obvious的杂志编辑兼摄影师Jerris Madison说，这个家庭此时并不知道他的死因。根据麦迪逊的说法，奈特最终被亲人所包围.
Knight在7月份在Facebook上透露了他的腹部麻烦，在一篇帖子中解释了为什么他从朋友和社交媒体“消失”。该职位后来被删除。麦迪逊代表奈特的家人，与今天分享了奈特的帖子：
“今年真的对我的健康造成了严重影响……很糟糕。简而言之，IBS是一种胃肠道疾病，我吃的食物，我的身体不吸收（吸收不良）我吃的营养素。另外，b / c我有一个“漏肠”，肠道开口，食物中的毒素泄漏到我的血液中，可导致自身免疫性疾病（糖尿病，狼疮，腹腔疾病，类风湿性关节炎）.
B / C，我患有慢性腹痛/腹泻/恶心，极度疲劳和疲惫，食物敏感/过敏，大脑模糊，头痛等。最近，我发展了一些急性自身免疫反应，如牛皮癣，发炎关节和小呼吸问题。“
尽管IBS可以对患者的生活质量产生重大影响，但“它不会带来死亡率或癌症风险，”匹兹堡大学医学中心神经胃肠病学和运动中心主任David Levinthal博士说。 “这是一种非常常见的疾病，可引起腹泻，便秘和频繁的腹痛。”
Levinthal说，肠道疾病可能是致命的。虽然他们的一些症状可能类似于IBS的症状，但有许多症状并非如此.
在Facebook的帖子中，奈特写道，他没有癌症.
然而，一个线索可能是骑士自己注意到的症状，例如吸收营养素的问题.
Levinthal虽然无法对Knight的死亡作出具体评论，但他表示“慢性营养不良与克罗恩病密切相关。克罗恩病引起消化系统炎症，被认为是免疫系统功能失常的结果。“
Levinthal说，体重减轻可能是“克罗恩病的另一个红旗”.
IBS“可能会给某人的生活造成很大的痛苦，但这并不是致命的，”宾夕法尼亚大学胃肠病学系助理教授Nitin Ahuja博士说。 “但它可以模仿其他胃肠道疾病。”
Ahuja说，警告症状会导致更严重的疾病，也许是炎症性肠病（IBD），包括胃肠道失血，体重减轻和发烧或发冷。.
Ahuja说，IBD可能会出现“一系列结构性并发症”，并补充说“严重的病例可能会危及生命”。
Levinthal说，底线是“许多肠道疾病都可能出现IBS样症状。患者不应将自己诊断为患有IBS，而应由临床医生进行评估。确定基础诊断是适当治疗的关键。“

The cause of death of designer Mychael Knight, a finalist on “Project Runway,” is still a mystery. The 39-year-old fashion star had been openly discussing his struggles with irritable bowel syndrome and extreme weight loss in recent months, leading many to speculate whether the disease may have played a role in his death. Doctors believe this is unlikely. Knights close friend, Jerris Madison, editor and photographer for Obvious magazine, said the family does not yet know the cause of his death. According to Madison, Knight was ultimately surrounded by loved ones. In July, Knight revealed his abdominal troubles on Facebook, explaining why he had “disappeared” from friends and social media in a post that was later deleted. Madison, representing Knights family, shared Knights post today: “This year has really taken a toll on my health…its been rough. In short, IBS is a gastrointestinal disease where the food I eat, my body doesnt absorb (malabsorption) the nutrients I eat. Additionally, b/c I have a leaky gut, the opening in my intestines, toxins from food leak into my bloodstream, which can lead to autoimmune diseases (diabetes, lupus, abdominal issues, rheumatoid arthritis). B/C, I suffer from chronic abdominal pain/diarrhea/nausea, extreme fatigue and exhaustion, food sensitivities/allergies, brain fog, headaches, etc. Recently, Ive developed some acute autoimmune reactions like psoriasis, inflamed joints, and minor respiratory issues.” Former “Project Runway” finalist and fashion designer Mychael Knight passed away on October 17, 2017, after struggling with intestinal issues in Georgia. Although IBS can have a significant impact on a patients quality of life, “it does not carry a mortality or cancer risk,” said Dr. David Levinthal, director of neurogastroenterology and motility center at the University of Pittsburgh Medical Center. “Its a very common disease that can cause diarrhea, constipation, and frequent abdominal pain.” Levinthal said intestinal diseases can be fatal. While some of their symptoms may be similar to those of IBS, there are many symptoms that are not. In his Facebook post, Knight wrote that he did not have cancer. However, one clue may be symptoms
