What causes hemorrhoidal bleeding, and how is it treated?

好的，我现在需要帮用户把一段关于痔疮的中文内容翻译成英文。先通读一遍原文，了解整体结构和主要内容。

用户提到小林因为吃辛辣食物导致痔疮发作，便血严重，然后解释了痔疮的成因，包括久坐、辣椒素刺激、其他因素如冷热刺激、便秘等。接着讲便血的后果，如贫血、瘙痒，然后介绍治疗方法，特别是九华痔疮栓的成分和效果，最后给出预防建议。

翻译时要注意医学术语的准确性，比如“痔疮”是hemorrhoids，“便血”是rectal bleeding，“栓剂”是suppository。有些中药成分如白及和侧柏叶，需要找到对应的英文名，可能直接用拼音或者拉丁学名。比如白及是Bletilla striata，侧柏叶是Platycladus orientalis leaves。

还要注意句子的连贯性，比如因果关系和逻辑顺序。例如，用户提到辣椒素刺激胃肠黏膜，导致肛门灼热和出血，这部分要准确传达。另外，九华痔疮栓的成分和作用机制需要详细翻译，特别是止血效果的数据，比如“缩短凝血时间10分钟内起效”要处理成英文的专业表达。

用户可能的需求是让英文读者理解痔疮的成因、治疗方法和预防措施，特别是推广九华痔疮栓的效果。所以翻译时要保持信息的完整性和宣传点，比如强调止血速度快，是其他产品的三倍。

另外，注意文化差异，比如“菊”部这样的幽默表达，可能需要适当调整，保持专业又不失原意。最后，检查语法和术语是否正确，确保翻译后的内容流畅准确。

Recently, Xiao Lin once again suffered the agony of hemorrhoids. Due to the cold weather, he indulged in spicy, irritant foods like hotpot, barbecue, and beer. While satisfying his cravings, his "backside" paid the price—his previously dormant hemorrhoids flared up, causing frequent rectal bleeding during bowel movements. Why does spicy food trigger hemorrhoids? What causes hemorrhoidal bleeding, and how can it be treated?  

### Causes of Hemorrhoidal Bleeding  

Prolonged sitting or standing impairs venous return, leading to pelvic blood stagnation and congestion in abdominal organs. This overfills the hemorrhoidal veins, causing dilation, pressure, and impaired blood flow, which contribute to hemorrhoids. Capsaicin in spicy foods intensely irritates the gastrointestinal mucosa, causing hyperemia, accelerated peristalsis, and a burning sensation in the anal region, often inducing bleeding. Additional triggers include exposure to extreme temperatures, constipation, diarrhea, excessive alcohol consumption, and fatigue.  

### Risks of Untreated Hemorrhoidal Bleeding  

Initially, bleeding may appear as streaks on toilet paper or droplets, but severe cases can involve spurting blood. Chronic bleeding, like Xiao Lin’s, risks anemia, leading to pallor, fatigue, loss of appetite, and palpitations. Repeated prolapse of hemorrhoids weakens the anal sphincter, causing mucus leakage that irritates surrounding skin and triggers itching or eczema.  

### Treatment: Jiuhua Hemorrhoid Suppository  

To address bleeding, Xiao Lin sought a more effective medication. His doctor recommended **Jiuhua Hemorrhoid Suppository**, a traditional Chinese herbal remedy. Its key ingredients—**Bletilla striata** (*Bai Ji*) and **Platycladus orientalis leaves** (*Ce Bai Ye*)—are potent hemostatic agents. They accelerate platelet aggregation, boost thrombin production, and shorten clotting time, achieving止血 within 10 minutes (3x faster than other products).  

The brown, cone-shaped suppository is inserted into the anus post-bowel movement or before bedtime, directly targeting internal hemorrhoids. After cleansing the area with warm water, Xiao Lin applied one suppository daily. By morning, he experienced noticeable止血, reduced swelling, and pain relief.  

### Prevention and Care  

Early intervention with medications like Jiuhua Suppository minimizes discomfort. For severe prolapse or excessive bleeding, surgical treatment at a hospital is advised. Maintain healthy habits: avoid prolonged sitting/standing, limit alcohol and spicy foods, and stay active to keep hemorrhoids at bay.
