- Gastroparesis is characterized by delayed gastric emptying in the absence of a mechanical obstruction.
- Most cases of gastroparesis (more than one-third) are idiopathic, i.e. have an unknown cause. Other common causes are diabetes and postgastric surgery. (Parkman 2015)
- Patients with idiopathic gastroparesis are typically young or middle-aged women. (Parkman 2015)
- Although the true prevalence of gastroparesis is unknown, US data suggest that it may affect 2% of the general population. (Parkman 2015)
- Gastroparesis is associated with psychological distress and poor quality of life.
- 24% of patients have combined anxiety and depression. (Woodhouse et al. 2017)
- Two-thirds of people affected by gastroparesis report having a poor or fair quality of life. (Yu et al. 2017)
- Nearly one-third (30%) report they are not working because of the condition. (Yu et al. 2017).
- The economic burden of gastroparesis in Canada is unknown.
- In the US, mean hospital charges increased significantly by 159% from US$13,350 in 1997 to US$34,585 per patient in 2013, after adjustment for inflation. At the national level, the costs of hospital visits also increased substantially, by 1026%, from $50,456,642 to $568,417,666. (Wadhwa et al. 2017)
