病 根 是 在 国 内 种 下 的，当 时 国 内 的 医 生 也 基 本 上 是 这 么 确 诊 的。现 在 的 情 况 是 一 遇 冷（ 吃 或 受 凉） 左 部 小 腹 就 疼，大 便 也 不 成 型，肚 子 里 的 气 也 非 常 多。最 明 鲜 的 是 发 病 时 小 腹 上 会 出 现 非 常 痒 的 一 片 小 泡。平 时 吃 的 也 就 一 般 家 常 饭，生 活 基 本 上 是 规 律 的，老 去 健 身，面 上 看 起 来 还 让 人 觉 得 身 体 怪 不 错 的。 有 一 毛 病 是 一 天 抽 四 五 根 烟，反 正 抽 烟 增 加 痛 感 是 我 已 觉 出 来 的 了。

nutrition: This disease is caused by the immune reaction to the gut. It is hard to cure. I think you can keep intake the medicine the doctor prescribed for you. ( You must have them because you should get the treatment when you were in China. At the same time, you can increase the food which is rich in w-3 polyunsaturated fatty acid that is commonly contained in the fish such as salmon,tuna... Because they can replace the w-6 fatty acid in your body. and their pruducts can inhibit the inflammatary products from the products produced by the w-6 faaty acids. You will get benefit from the long run even you may not feel the benefit. This is commonly recommended for the patients like you in US.

chuge: Chronic inflammation of the colon leads to colonitis(or colitis in the case of inflammatory bowel disease, IBD). However, acute episodes or persisting states are very important. In that situation, the most efficient step is to find the causes. Usually, chronic infection with virus or bacteria are suspected, although they are self-limiting, and the results of antibiotics treatment is very clear. I support to use antibiotic only when culture and drug tests are obtained. Undirected treatment will even worsen colonitis.

Stool exams are invariably necessary during acute episodes or persisting diarrhea, including exams of pathogen such as bacteria, virus (CMV, seen in cells)parasites and breeding etc.If the case still can not explained for a long time, endoscope and biopsy are adopted. I say one young man suffer from lymphoma.

IBDs including ulcerative colitis (UC) and granulomatous ileo-colitis (Crohn's disease)are easily diagnosed so that I suspect that they are "over-diagnosed".

Treatment: sulfasalazine or slow-releasing 5-ASA,corticosteroid, sometimes anti-diarrhea; surgery in dyplasia and cancer. Maybe, you need stop smoking, as yin-er mentioned. Again, it is important for patients to understand the disease, not to ask for better medicine.

jt: in general, colitis is an inflammtory process in large intestines. one of most commom symtoms is chronic diarrhea. usually, stools are very mucous, and stool hemoccult test is postitive. in the extreme case, patients can present with bloody diarrhea. irritable bowel syndrome is not a really organic disorder. currently, we still haven't completely understood its etiology. however, most GI specialists agree that psychological factors do play a big role.

茵儿: 在国外就这个情况没有看过医生吗？如果是Irritable Bowel Syndrome (IBS)的话，饮食，药物，精神压力都有影响。药物如：抗高血压药，抗生素，尼古丁(你的香烟)，咖啡因，抗酸药，酒精等等。饮食方面，有些食物容易引起气涨，如：豆类，洋白菜，菜花，西蓝花，黄瓜，青椒，苏打汽水，啤酒，洋葱，油炸食物，还有口香糖。尽量不要漏过一餐饭不吃，然后大撮一顿。其实牛奶也可能是腹泻的原因，如果你有lactose intolerance 的话。不过要先检查缺点一下，不要从此就不喝牛奶了，那又会影响钙的摄取量。 *少喝咖啡，酒 *如果对果糖耐受力不好，少喝果汁 *少吃多餐 *少吃引起气涨的食物如果你经常腹泻的话，我怀疑你能否摄入足够的营养。你还健身，能量需求会更多。建议你去医院检查一下： complete blood count, stool examination, sigmoidoscopy, or colonoscopy(especially for those >50 yesrs of age). 你说“最明显的是发病时小腹上会出现非常痒的一片小泡”，我想听听别人的说法。到底是IBS还是Colitis. 不过Colitis也有食物的诱因，可以追查。
