The search term Dr Gina Sims Gastroenterologist appears to refer to Dr. Gina Sam, MD, MPH, not to a separately verified gastroenterologist whose professional surname is Sims. Current institutional records from NYC Health + Hospitals and Guthrie identify the physician as Gina Sam, with documented training in gastroenterology and a longstanding clinical interest in gastrointestinal motility disorders.
This distinction is important because a website titled around “Dr Gina Sims Gastroenterologist” uses the surname Sims in its branding and headings, while its own About page identifies the physician as Dr. Gina Sam and provides education and career information that matches independent medical sources.
Dr Gina Sims Gastroenterologist: Why the Name Is Confusing
The clearest finding from independent research is that established healthcare institutions use the name Gina Sam, MD, rather than Gina Sims. NYC Health + Hospitals currently lists Gina Sam in both gastroenterology and internal medicine at NYC Health + Hospitals/Kings County in Brooklyn. Its credential record gives the same medical-school, residency and fellowship history found in other reliable sources.
Guthrie also lists a Gina Sam, MD under gastroenterology, and its 2026 materials identify Gina Sam, MD, MPH as a gastroenterologist. She appeared as a presenter at Guthrie’s March 26, 2026 colon-cancer prevention and nutrition program.
By contrast, searches for a separate gastroenterologist formally named “Gina Sims” primarily lead back to the DrGinaSims.com website. That site’s About page switches to “Dr. Gina Sam” and describes credentials matching the institutional record.
For readers trying to verify credentials, make an appointment or locate medical records, Gina Sam, MD or Gina Sam, MD, MPH is the name supported by the strongest independent evidence reviewed for this article.
Who Is Dr. Gina Sam?
Dr. Gina Sam is a physician trained in internal medicine and gastroenterology. Gastroenterology covers diseases and disorders affecting the digestive system, including the esophagus, stomach, small intestine and colon, as well as related digestive organs.
Her career is particularly associated with gastrointestinal motility, the study and treatment of problems involving how muscles and nerves move food and waste through the digestive tract. Historical academic records connect her with work involving esophageal motility, anorectal function, chronic constipation and related functional gastrointestinal problems.
A concise summary of the independently documented record is:

Education and Medical Training
Tufts University School of Medicine
NYC Health + Hospitals records Dr. Sam’s medical education at Tufts University School of Medicine in 2003. Historical Stony Brook material provides additional context, stating that she received both an MD and an MPH in Community Health from Tufts.
Lenox Hill Hospital
She subsequently trained in internal medicine at Lenox Hill Hospital in New York City. Her NYC Health + Hospitals profile records an internship completed in 2004 and residency completed in 2006.
Internal-medicine training is the standard foundation before physicians enter a gastroenterology fellowship.
NYU Gastroenterology Fellowship
Dr. Sam completed her gastroenterology fellowship at New York University School of Medicine in 2009, according to NYC Health + Hospitals.
A Stony Brook University publication from 2010 also described her NYU gastroenterology training and noted that she pursued additional work in neurogastroenterology and gastrointestinal motility.
Her Specialization in Gastrointestinal Motility
Gastrointestinal motility refers to the coordinated muscle and nerve activity that moves material through the digestive tract. Problems with this system can contribute to symptoms such as difficulty swallowing, abnormal stomach emptying, constipation or difficulty coordinating bowel movements.
Stony Brook University’s gastroenterology publication described Dr. Sam as having specialized training involving esophageal manometry, pH testing, anorectal manometry and biofeedback. The same publication said she had received additional clinical training in neurogastroenterology and GI motility at the University of Iowa.
This background differentiates motility medicine from ordinary evaluation of occasional heartburn or an uncomplicated stomach illness. Motility specialists may become involved when symptoms are persistent and conventional imaging or endoscopy does not fully explain what is happening.
Career at Stony Brook
Dr. Sam joined Stony Brook University’s Division of Gastroenterology in July 2009, according to a university publication. At the time, Stony Brook described her as a motility specialist involved in developing a multidisciplinary GI Motility Center.
The publication discussed her expertise in areas such as esophageal disease, anorectal manometry and biofeedback for chronic constipation and fecal incontinence. It also documented plans for research involving Barrett’s esophagus.
These records are useful because they were published by the institution itself rather than by a commercial physician directory.
Dr. Gina Sam and Mount Sinai
Dr. Sam later had a documented professional role at The Mount Sinai Hospital.
A Mount Sinai publication from March 2015 identified Gina Sam, MD, MPH as Director of the Gastrointestinal Motility Center at The Mount Sinai Hospital.
Her Mount Sinai affiliation also appears in medical research. A peer-reviewed paper on the long-term effects of adjustable gastric bands on esophageal motility included Gina Sam as a co-author and was published in Obesity Surgery. Mount Sinai’s academic research database lists her among the authors.
PubMed also records a 2016 Gastroenterology publication co-authored by Gina Sam with an affiliation at Mount Sinai Hospital in New York.
These sources establish a historical Mount Sinai connection. They should not, however, be interpreted as proof that she currently holds the same Mount Sinai position in 2026. The current institutional listings located during this research instead include Guthrie and NYC Health + Hospitals.

Research and Academic Work
Dr. Sam’s publication record includes work related to motility and digestive disorders.
One particularly relevant paper examined esophageal motility after long-term adjustable gastric band use. Published in Obesity Surgery in 2018, it evaluated patients undergoing gastric-band removal using high-resolution esophageal manometry.
More recently, Mount Sinai’s academic research portal lists Dr. Sam and Satish S.C. Rao as authors of the chapter “Dyssynergic Defecation and Constipation” in the Handbook of Gastrointestinal Motility and Functional Disorders, published in 2024.
Dyssynergic defecation is a bowel disorder in which the muscles needed for normal evacuation do not coordinate correctly. Its presence among her academic work fits her longer history in GI motility medicine.
Where Does Dr. Gina Sam Practice Now?
As of the current 2026 information reviewed for this article, Guthrie lists Gina Sam, MD, in gastroenterology and indicates that she is accepting new patients in its provider-search results. Guthrie also publicly identified her as a gastroenterologist at its March 2026 colon-cancer prevention event.
NYC Health + Hospitals simultaneously maintains a current profile for Gina Sam, MD at NYC Health + Hospitals/Kings County in Brooklyn, listing gastroenterology and internal medicine as her specialties.
Older physician directories may show other hospitals, offices or addresses from previous stages of her career. Because physician affiliations and clinic schedules can change, patients should confirm the exact location and appointment availability through the healthcare institution itself rather than relying on an old third-party listing.
Private Practice and the Gastrointestinal Motility Institute
Dr. Sam’s professional website describes Gina Sam MD/MPH P.C. and the Gastrointestinal Institute of Motility and Integrative Health, also referred to as G.I.M.I.H. The site emphasizes gastrointestinal motility and functional disorders and mentions services such as anorectal manometry and biofeedback.
Her Tufts alumni profile has also previously identified her as founder of the Institute of Gastrointestinal Motility Disorders and Integrative Health.
Current hospital affiliation and private-practice activity are separate issues, so someone seeking treatment should verify which practice or health system is handling the specific appointment.
What Conditions Is She Associated With?
Dr. Sam’s documented specialty history is strongest in gastrointestinal motility and functional digestive medicine. Her professional materials describe work involving conditions and symptoms such as chronic constipation, IBS, pelvic-floor dysfunction, fecal incontinence, swallowing disorders and other motility problems.
Her broader gastroenterology background also encompasses routine digestive evaluation and procedures typical of the specialty. Exact services available at a particular office can vary, so a historical service list should not automatically be treated as a current menu of procedures.
Importantly, the existence of a physician’s expertise does not mean a particular symptom has one specific diagnosis. Persistent digestive symptoms often have overlapping causes and require individual clinical assessment.
What Is the Connection With Emma Digestive Supplements?
Dr. Sam’s name also appears prominently in marketing for Emma, a digestive-health supplement. Promotional materials for the product present her as a gastroenterologist associated with and endorsing the formula.
Her medical qualifications and a supplement’s effectiveness are two separate questions. A doctor’s credentials do not by themselves establish that a commercial supplement has been proven to treat a disease.
Consumers considering any supplement should look separately at the product’s ingredients, clinical evidence, possible medication interactions and regulatory status. People with persistent gastrointestinal symptoms, bleeding, unexplained weight loss, severe pain or other concerning symptoms should not use a supplement as a substitute for appropriate medical evaluation.
Is Dr. Gina Sam Board Certified?
Several physician profiles and her professional materials describe Dr. Sam as board certified in gastroenterology, including current healthcare directories.
Because board-certification status can be maintained, renewed or change over time, anyone who needs formal credential verification for medical decision-making should confirm the current status directly through the relevant certifying organization rather than relying solely on a biography or directory.
Her underlying specialist training itself is independently documented by NYC Health + Hospitals, which confirms completion of an NYU gastroenterology fellowship in 2009.
What Is Confirmed and What Is Not?
Several parts of Dr. Sam’s professional history are supported by strong institutional evidence: her Tufts medical education, Lenox Hill internal-medicine residency, NYU gastroenterology fellowship, past work in GI motility, historical Mount Sinai role and current listings with healthcare systems.
Other claims found online require more caution. Promotional websites use titles such as “leading” or “top” gastroenterologist, but those are subjective marketing descriptions rather than standardized medical credentials. Likewise, no reliable evidence located for this article supports a specific personal net-worth or income estimate, so financial figures circulating on biography sites should not be treated as established facts.
The most significant correction is the name itself: independent medical records consistently point to Gina Sam, not Gina Sims.
Frequently Asked Questions
Is Dr Gina Sims Gastroenterologist a real doctor?
The search appears to refer to a real physician, but the independently documented name is Dr. Gina Sam, MD, MPH. NYC Health + Hospitals and Guthrie both identify Gina Sam as a gastroenterologist.
Are Dr. Gina Sims and Dr. Gina Sam the same person?
The available evidence strongly indicates that online material using “Dr. Gina Sims” is referring to Dr. Gina Sam. The DrGinaSims.com About page itself switches to the name Gina Sam and lists the same Tufts, Lenox Hill and NYU training documented by independent healthcare institutions.
What does Dr. Gina Sam specialize in?
She is a gastroenterologist with a substantial historical focus on gastrointestinal motility and functional digestive disorders. Institutional records document training and work involving esophageal and anorectal motility, manometry, chronic constipation and related gastrointestinal conditions.
Was Dr. Gina Sam a doctor at Mount Sinai?
Yes. Mount Sinai published material identifying Gina Sam, MD, MPH as Director of its Gastrointestinal Motility Center in 2015, and Mount Sinai’s academic database documents research bearing her name.
That evidence confirms a historical role. It does not establish that she currently holds the same Mount Sinai position in 2026.
Where is Dr. Gina Sam practicing in 2026?
Current sources reviewed include a Guthrie gastroenterology listing and an NYC Health + Hospitals profile at Kings County in Brooklyn. Guthrie also featured her as a gastroenterologist at a March 2026 educational event.
Patients should confirm the precise office and appointment availability before traveling because provider locations can change.
Did Dr. Gina Sam develop or endorse Emma?
Commercial Emma materials prominently associate Dr. Sam with the digestive supplement and feature her endorsement.
That commercial association should be considered separately from her verified medical training. Claims about a supplement’s effectiveness require evidence for the specific product, not simply evidence that an associated physician is qualified.
