What is dumping syndrome?
Dumping syndrome is a group of symptoms that happen when food moves too fast from the stomach to the small intestine. It can prevent your body from properly absorbing nutrients you need. When you’ve had surgery on your stomach or intestine, you may develop dumping syndrome.
Some symptoms of dumping syndrome can develop as early as 30 minutes after eating or drinking. Symptoms may include:
- feeling sick to your stomach (nausea) or throwing up (vomiting)
- stomach pain or cramping
- loose stool (diarrhea)
- feeling full or bloated
- a faster heart beat
Some symptoms develop 1 to 3 hours after eating and are called late symptoms. Late symptoms happen when there are changes to the amount of insulin (a hormone that controls blood sugar levels) and sugar in your blood. These symptoms include:
- red or hot skin (flushing) or sweating
- feeling like you need to lie down right away
- feeling weak or dizzy
- feeling anxious, nervous, or shaky
- a drop in blood pressure
Many people manage dumping syndrome by changing the way they eat, such as by:
- eating smaller meals throughout the day
- limiting food and drinks higher in sugar
- choosing foods with fibre
- not drinking fluids with meals or snacks
Your dietitian will tell you which foods are best to eat after having bariatric surgery and which foods to limit to help prevent dumping syndrome. Talk to your healthcare team if you develop any symptoms of dumping syndrome.
How will I know if I’m not getting enough fluids after surgery?
If you’re not getting enough fluid, you may get dehydrated or constipated.
Signs and symptoms of being dehydrated include:
- feeling thirsty
- peeing (urinating) less often
- dark pee (urine)
- dry skin
- feeling tired
- feeling light-headed (dizzy)
Signs of being constipated include:
hard and dry stool
having a hard time passing stool or painful bowel movements
having fewer than 3 bowel movements a week
Talk to your healthcare provider if you aren’t able to eat or drink well or think you’re dehydrated or constipated.
