This topic is about someone who has a colostomy and is experiencing frequent burping, discomfort on the left side under the breast, and a lower than usual colostomy output. They are worried about the possibility of a blockage and have reduced their food intake as a precaution. They are curious if others have experienced similar symptoms.

Here are some helpful insights and advice:

1. Early signs of a blockage might include low output, discomfort in the upper abdomen, and excessive gas.

2. Some self-help measures for suspected minor blockages include:
- Drinking carbonated beverages to help move gas and stool.
- Lying on your stomach for about 15 minutes while gently massaging your abdomen.
- Using a hot-water bottle to relax abdominal muscles.
- Staying hydrated by drinking plenty of fluids and avoiding solid food for up to 24 hours.

3. If these measures do not help or if new or worsening symptoms appear, it is important to contact medical services immediately.
