Background:
Despite its significant health burden, there is a lack of national-level temporal patterns in gastrointestinal bleeding (GIB) mortality.
Objectives:
To comprehensively decipher the annual and monthly trend of GIB-related mortality in the United States.
Design:
Cross-sectional study.
Methods:
We analyzed the National Vital Statistic System database, which documents more than 99% of the annual deaths in the United States for GIB-related deaths from January 2010 to May 2023. Annual and monthly age-standardized mortality rates were estimated and categorized by age, sex, and bleeding site. Joinpoint regression was performed for trend analysis. Prediction modeling was conducted to determine the GIB-associated excess mortality.
Results:
A total of 529,094 and 210,641 GIB-associated deaths occurred before and after 2020, respectively. Following a stably decreasing trend between 2010 and 2019, there was an excess mortality rate during the pandemic which peaked in 2021. The monthly mortality trend showed spikes corresponding to the outbreak of variants. Importantly, excess GIB-related mortality resolved in 2023, with the convergence of predicted and observed mortality rates. Subgroup analysis showed that young males (aged 19-44 years) were affected the most during the pandemic, with excess mortality rates of 35.80%, 52.77%, and 31.46% in 2020, 2021, and 2022, respectively. While the increasing trend of upper GIB was accentuated during the pandemic, lower GIB showed a reversal of the pre-pandemic decreasing trend.
Conclusion:
Our findings demonstrate the trend of GIB-related mortality, underscoring an increased excess death during the pandemic followed by a resolution in 2023. We identify subpopulations vulnerable to the pandemic.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
