Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Umar Ahmad, M.D.[2]

Overview

Incidence and prevalence varies depending on the procedure or disease leading to dumping syndrome.

The incidence of patients who have undergone gastric surgery ranges from approximately 20,000 to 50,000 per 100,000.^[1]
Out of these about 1-5% reported severe symptoms.
After truncal vagotomy with drainage the incidence of dumping syndrome has been reported to be 6,000 to 14,000 per 100,000.
After proximal vagotomy without drainage the incidence of dumping syndrome has been reported to be is less than 2,000 per 100,000.
After partial gastrectomy the incidence of dumping syndrome has been reported to be 14,000 to 20,000 per 100,000.
Proximal vagotomy is a fairly newer procedure that leads to lower incidence rates due to the minimized interference in gastric emptying.^[2]

Since the advent of proton pump inhibitors, the need for surgery has decreased and so has the incidence of dumping syndrome.
In gastric surgery 1 out of 10 people develop dumping symptoms.
In esophagectomy 1 out of 2 people developed symptoms of dumping syndrome.

In 2012, the mortality rate of bariatric surgery leading to dumping syndrome was approximately 1,000 per 100,000 individuals.^[4]

People aged 45-74 are 2 times more likely to be diagnosed with dumping syndrome
Children aged less than 1 year are 3 times less likely to be diagnosed with dumping syndrome^[5]
Toddlers and preschoolers are are 7 times less likely to be diagnosed with dumping syndrome^[5]
Children aged 5 to 14 years old are 10 times less likely to be diagnosed with dumping syndrome^[5]
Elderly people whose ages are over 75 years old are 11 times less likely to be diagnosed with dumping syndrome^[5]
Teenagers and adults aged 15 to 29 years old are 23 times less likely to be diagnosed with dumping syndrome^[5]

Females have a higher chance of being diagnosed with dumping syndrome in comparison to men.^[5]

People who are of white ethnicity tend to be more likely diagnosed with dumping syndrome.^[5]
