Gastroenterology is the most competitive internal medicine subspecialty in the United States. Over the past 12 years, it has consistently had more applicants per available position than any other IM fellowship, including cardiology and hematology/oncology. In 2024, 99.6% of GI fellowship positions filled, meaning almost no spots went unclaimed.
How GI Compares to Other Fellowships
A study published in Proceedings (Baylor University Medical Center) analyzed 12 years of fellowship match data from 2010 to 2022. Gastroenterology had the highest specialty competition ratio (SCR) of any internal medicine subspecialty at 1.58, meaning roughly 1.6 applicants competed for every available spot. Cardiovascular disease came in second at 1.44, followed by hematology/oncology at 1.42. That gap has remained consistent, with both positions and applications growing steadily over the study period (positions up 4.61%, applications up 3.81%).
In practical terms, this means that even strong candidates sometimes go unmatched. It’s not uncommon for well-qualified applicants to apply broadly to 30 or more programs.
The Numbers Behind the Match
In the 2024 NRMP fellowship match, 1,114 applicants listed gastroenterology as their preferred specialty. Of those who matched, 404 were US MD graduates. The fill rate of 99.6% tells you how programs feel about the applicant pool: they had no trouble finding candidates they wanted. The most recent 2025 cycle showed a similar picture, with 759 positions offered and 99.5% filled.
Across all internal medicine subspecialty matches in 2025, US MD graduates made up 43.9% of matched physicians. The rest came from DO programs, international medical graduates, and other pathways. For gastroenterology specifically, the field draws applicants from all these groups, which intensifies competition further.
What Programs Look For
NRMP program director surveys consistently highlight a cluster of qualities that matter most in selecting fellows: professionalism, quality of patient care, clinical competency, ethics, and communication skills. These may sound generic, but they reflect how interviews and letters of recommendation are evaluated. A glowing letter that specifically speaks to your clinical judgment and professionalism carries more weight than one that lists research output alone.
That said, research productivity is a de facto gatekeeper. GI fellowship applicants are generally expected to have multiple peer-reviewed publications, abstracts, and presentations. Many competitive applicants dedicate a full year (or more) to research during or after residency to strengthen their applications. Programs at academic medical centers tend to weigh research more heavily, while community-based programs may place greater emphasis on clinical performance and fit.
Strong performance during your internal medicine residency is foundational. In-training exam scores, evaluations from attendings, and the reputation of your residency program all factor into whether you get interview invitations. Letters of recommendation from gastroenterologists who know your clinical work well are particularly valuable.
Competition Is Still Increasing
The trend line points in one direction. Both the number of GI fellowship positions and the number of applicants have grown since 2010, but applicant growth has kept pace with (and at times outstripped) position growth. The researchers who tracked this 12-year trend concluded that competitiveness within the GI fellowship match will continue to increase.
Several forces drive this. Gastroenterology offers a favorable mix of procedural work and cognitive medicine, strong compensation relative to other IM subspecialties, and manageable lifestyle compared to surgical fields. These factors attract a large share of internal medicine residents year after year. The growing prevalence of GI conditions like inflammatory bowel disease and fatty liver disease also means high demand for gastroenterologists in practice, which reinforces interest in the field.
The Application Timeline
Gastroenterology follows the July match cycle through ERAS (Electronic Residency Application Service). For the 2026 cycle, the ERAS season opens June 4, 2025. Applicants can begin submitting applications on July 2, 2025, and programs start reviewing them on July 16, 2025. Interviews typically take place in the fall, with match results following in December.
This timeline means you should have your application materials, including personal statement, letters of recommendation, and CV, finalized by late June. Research projects ideally need to be published or at least submitted by this point. Starting preparation during the second year of internal medicine residency is standard for applicants targeting GI.
What Unmatched Applicants Do
Given the competition, not everyone matches on their first attempt. Applicants who don’t match have a few paths forward. Some take a research year at an academic center to build their publication record and form connections with GI faculty who can advocate for them. Others pursue a related fellowship like hepatology or work as hospitalists while reapplying. A second application cycle with additional research and stronger letters often succeeds where the first did not, though there are no guarantees. Some applicants also broaden their scope to include community programs or less geographically desirable locations to improve their odds.
