Dumping syndrome is a condition that happens when food — especially sugar — moves too quickly from the stomach into the small intestine. It’s most common in people who’ve had stomach surgery, like gastric bypass or partial gastrectomy.
1. Early dumping (within 30–60 minutes after eating):
Early Dumping is caused by undigested food rushing into the small intestine.
- Symptoms include:
- Nausea
- Abdominal cramps
- Diarrhea
- Bloating
- Sweating
- Rapid heart rate
- Feeling faint or flushed
2. Late dumping (1–3 hours after eating):
Late dumping is caused by a spike in blood sugar followed by a rapid insulin response, leading to low blood sugar (reactive hypoglycemia)
- Symptoms include:
- Weakness
- Dizziness
- Sweating
- Shakiness
- Confusion or brain fog
- Hunger
