Definition

1. Noun:
   • Rectum: The final, straight portion of the large intestine, terminating at the anus. This is the primary anatomical meaning.
   • Hemorrhoids: In common, informal usage, "dom" is often used to refer to hemorrhoids (piles), especially in the context of the condition "lòi dom" (prolapsed hemorrhoids or rectal prolapse).

Usage Examples

• Noun:
  • Anh ấy bị đau ở vùng dom. (He has pain in the rectal area.)
  • Bệnh lòi dom gây ra nhiều khó chịu. (Hemorrhoids / Rectal prolapse causes a lot of discomfort.)

Advanced Usage

• "Lòi dom": A common Vietnamese medical term for prolapsed hemorrhoids or rectal prolapse, where rectal tissue protrudes from the anus.
  • Ông cụ phải phẫu thuật vì chứng lòi dom nặng. (The old man had to have surgery for severe rectal prolapse.)

Notes on Usage

• Register: The word "dom" is considered a direct, informal, and somewhat crude term in Vietnamese. It is primarily used in everyday speech, folk medicine contexts, or when discussing common ailments. In formal medical or polite contexts, the terms "trực tràng" (rectum) or "bệnh trĩ" (hemorrhoids) are strongly preferred.
• Specificity: While its core anatomical meaning is "rectum", its most frequent contemporary use is in the compound "lòi dom", which colloquially refers to hemorrhoids, though it technically describes prolapse.
