A colostomy bag is a medical device used by individuals who have undergone a colostomy, a surgical procedure where an opening (stoma) is created in the abdomen to divert waste from the colon into an external pouch. The bag collects stool that would normally be expelled through the rectum, providing a convenient and hygienic way for people to manage their waste. Colostomy bags are typically made of soft, durable materials and come in various sizes and styles, including closed and drainable options. They are designed to be discreet, secure, and comfortable, allowing for easy disposal and minimizing the risk of leaks or odors.
