Pooja Singhal, MD, AGAF, will never forget the time a female patient came in for gastroesophageal reflux disease and dysphagia treatment, revealing that she had already gone through multiple gastroenterologists to help diagnose and treat her ailments.
“We spent a whole visit talking about it,” said Dr. Singhal, a gastroenterologist, hepatologist, and obesity medicine specialist at Oklahoma Gastro Health and Wellness in Oklahoma City. During the exam, she discovered that her middle-aged patient was wearing an adult diaper for diarrhea and leakage.
Previous GI doctors told the patient they couldn’t help her and that she had to live with these symptoms. “I was just so shocked. I told her: This is not normal. Let’s talk more about it. Let’s figure out how we can manage it,” said Dr. Singhal, who has spent her career advocating for more education about GI conditions.
There are real barriers to patients opening up and sharing their symptoms, especially if they’re female. while ensuring that the correct knowledge gets across to the public, said Dr. Singhal.
An alumna of the American Gastroenterological Association’s (AGA) Future Leaders Program, Dr. Singhal has served as the private practice course director for AGA’s Midwest Women in GI Workshop. She is a also a four-time recipient of the SCOPY award for her work in raising community awareness of colorectal cancer prevention in Oklahoma. In an interview, she discussed the critical role women GI doctors play in assisting the unique needs of female patients, and why it takes a village of doctors to treat the complexities of GI disorders.
Why did you choose GI, and more specifically, what brought about your interest in women’s GI issues?
GI is simply the best field. While I was doing my rotation in GI as a resident, I was enthralled and humbled that the field of gastroenterology offered an opportunity to prevent cancer. Colon cancer is the second leading cause of cancer related deaths, and when I realized that we could do these micro-interventions during a procedure to remove polyps that could potentially turn into cancer — or give us an opportunity to remove carcinoma in situ — that’s what really inspired me and piqued my interest in GI. As I continued to learn and explore GI more, I appreciated the opportunity the field gave us in terms of using both sides of our brains equally, the right side and the left side.
I love the diagnostic part of medicine. You have this privilege to be able to diagnose so many different diseases and perform procedures using technical skills, exploring everything from the esophagus, liver, pancreas, small bowel, and colon.
But what I really appreciate about gastroenterology is how it’s piqued my interest in women’s digestive health. How it became very close to my heart is really from my patients. I’ve learned a lot from my patients throughout the years. When I was much younger, I don’t know if I really appreciated the vulnerability it takes as a woman to go to a physician and talk about hemorrhoids and diarrhea.
One of the comments I often receive is: ‘Oh, thank God you’re a female GI. I can be myself. I can share something personal and you would understand.’
Your practice places a specific emphasis on health and wellness. Can you provide some examples of how you incorporate wellness into treatment?
I feel like wellness is very commonplace now. To me, the definition of wellness is about practicing healthy habits to attain your maximum potential, both physically and mentally — to feel the best you can. My practice specifically tries to achieve that goal by placing a strong emphasis on education and communication. We provide journals where patients can keep track of their symptoms. We encourage a lot of discussion during visits, where we talk about GI diseases and how to prevent them, or to prevent them from happening again. If you’re going to do a hemorrhoid treatment that offers hemorrhoid banding, we talk about it in detail with the patient; we don’t just do the procedure.
We have a dietitian on staff for conditions like inflammatory bowel disease, Crohn’s and ulcerative colitis, celiac disease, IBS. Some of our older patients have pelvic organ prolapse and fecal incontinence. We have a pelvic floor therapist and a urogynecologist, and we work very closely with ob-gyn teams. My practice also takes pride in communicating with primary care physicians. We’ve had patients who have had memory loss or dementia or are grieving the loss of a loved one. And we prioritize communicating and treating patients as a whole and not focusing on just their GI symptoms.
As an advocate for community education on GI disorders, where is education lacking in this field?
I think education is lacking because there is an information delivery gap. I feel the public consumes information in the form of short social media reels. The attention span is so short and any scientific information, especially around diseases, can be scary and overwhelming. Whereas I think a lot of the medical community still interacts and exchanges information in terms of journals and publications. So, we are not really trained necessarily to talk about diseases in very simple terms.
We need more advocacy efforts on Capitol Hill. AGA has been good about doing advocacy work. I had an opportunity to go to Capitol Hill a couple of times and really advocate for policy around obesity medicine coverage and procedure coverage. I was fortunate to learn so much about healthcare policy, but it also made me appreciate that there are a lot of gaps in terms of understanding common medical diseases.
You’re trained in the Orbera Intragastric balloon system for weight reduction. How does this procedure differentiate from other bariatric procedures?
Intragastric balloon is Food and Drug Administration approved for weight loss. It’s a temporary medical device, so it’s reversible. No. 2, it’s a nonsurgical intervention, so it’s usually done in an outpatient setting. We basically place a deflated gastric balloon endoscopically, similar to an upper endoscopy method. We take a pin endoscope, a deflated balloon, which is made of medical-grade material, and we inflate it with adequate fluid. The concept is when the balloon is inflated, it provides satiety. It reduces the amount of space in the stomach for food. It slows down how quickly the food is going to leave. So you feel full much of the time. And it also helps decrease a hormone called ghrelin, which is responsible for hunger. It can make a big difference when people are gaining weight and in that category of overweight before they progress to obese.
As I tell everybody, obesity is a chronic lifelong disease that is very complex and requires lifelong efforts. So, it’s truly a journey. What’s made this procedure a success is follow-up and the continued efforts of dietitians and counseling and incorporating physical exercise, because maintenance of that weight loss is also very important. Our goal is always sustained weight loss and not just short-term weight loss.
As the practice course director for the AGA’s Midwest Women in GI Workshop, can you tell me how this course came about? What does the workshop cover?
This workshop is a brainchild of AGA. This will be the third year of having these workshops. It’s been divided into regional workshops, so more people can attend. But it arose from the recognition that there is a need to have a support system, a forum where discussions on navigating career and life transitions with grace can happen, and more resources for success can be provided.
There is so much power in learning from shared experiences. And I think that was huge, to realize that we are not alone. We can celebrate our achievements together and acknowledge our challenges together, and then come together to brainstorm and innovate to solve problems and advocate for health equity.
You’ve been involved with community, non-profit organizations like the Homeless Alliance in Oklahoma City. How has this work enriched your life outside of medicine?
I feel like we sometimes get tunnel vision, talking to people in the same line of work. It was extremely important for me to broaden my horizons by learning from people outside of the medical community and from organizations like Homeless Alliance, which allowed me a platform to understand what my community needs. It’s an incredible organization that helps provide shelter not only for human beings, but also pets. The freezing temperatures over the last few months provided unique challenges like overflow in homeless shelters. I’ve learned so many things, such as how to ask for grants and how to allocate those funds. It has been absolutely enriching to me to learn about my community needs and see what an amazing difference people in the community are making.

The guidelines emphasize four-hour gastric emptying studies over two-hour testing. How do you see this affecting diagnostic workflows in practice?
Dr. Staller: Moving to a four-hour solid-meal scintigraphy will actually simplify decision-making. The two-hour reads miss a meaningful proportion of delayed emptying; standardizing on four hours reduces false negatives and the “maybe gastroparesis” purgatory that leads to repeat testing. Practically, it means closer coordination with nuclear medicine (longer slots, consistent standardized meal), updating order sets to default to a four-hour protocol, and educating front-line teams so patients arrive appropriately prepped. The payoff is fewer equivocal studies and more confident treatment plans.
Metoclopramide and erythromycin are the only agents conditionally recommended for initial therapy. How does this align with what is being currently prescribed?
Dr. Staller: This largely mirrors real-world practice. Metoclopramide remains the only FDA-approved prokinetic for gastroparesis, and short “pulsed” erythromycin courses are familiar to many of us—recognizing tachyphylaxis limits durability. Our recommendation is “conditional” because the underlying evidence is modest and patient responses are heterogeneous, but it formalizes what many clinicians already do: start with metoclopramide (lowest effective dose, limited duration, counsel on neurologic adverse effects) and reserve erythromycin for targeted use (exacerbations, bridging).
Several agents, including domperidone and prucalopride, received recommendations against first-line use. How will that influence discussions with patients who ask about these therapies?
Dr. Staller: Two points I share with patients: evidence and access/safety. For domperidone, the data quality is mixed, and US access is through an FDA IND mechanism; you’re committing patients to EKG monitoring and a non-trivial administrative lift. For prucalopride, the gastroparesis-specific evidence isn’t strong enough yet to justify first-line use. So, our stance is not “never,” it’s just “not first.” If someone fails or cannot tolerate initial therapy, we can revisit these options through shared decision-making, setting expectations about benefit, monitoring, and off-label use. The guideline language helps clinicians have a transparent, evidence-based conversation at the first visit.
The guidelines suggest reserving procedures like G-POEM and gastric electrical stimulation for refractory cases. In your practice, how do you decide when a patient is “refractory” to medical therapy?
Dr. Staller: I define “refractory” with three anchors.
1. Adequate trials of foundational care: dietary optimization and glycemic control; an antiemetic; and at least one prokinetic at appropriate dose/duration (with intolerance documented if stopped early).
2. Persistent, function-limiting symptoms: ongoing nausea/vomiting, weight loss, dehydration, ER visits/hospitalizations, or malnutrition despite the above—ideally tracked with a validated instrument (e.g., GCSI) plus nutritional metrics.
3. Objective correlation: delayed emptying on a standardized 4-hour solid-meal study that aligns with the clinical picture (and medications that slow emptying addressed).
At that point, referral to a center with procedural expertise for G-POEM or consideration of gastric electrical stimulation becomes appropriate, with multidisciplinary evaluation (GI, nutrition, psychology, and, when needed, surgery).
What role do you see dietary modification and glycemic control playing alongside pharmacologic therapy in light of these recommendations?
Dr. Staller: They’re the bedrock. A small-particle, lower-fat, calorie-dense diet—often leaning on nutrient-rich liquids—can meaningfully reduce symptom burden. Partnering with dietitians early pays dividends. For diabetes, tighter glycemic control can improve gastric emptying and symptoms; I explicitly review medications that can slow emptying (e.g., opioids; consider timing/necessity of GLP-1 receptor agonists) and encourage continuous glucose monitor-informed adjustments. Pharmacotherapy sits on top of those pillars; without them, medications will likely underperform.
The guideline notes “considerable unmet need” in gastroparesis treatment. Where do you think future therapies or research are most urgently needed?
Dr. Staller: I see three major areas.
1. Truly durable prokinetics: agents that improve emptying and symptoms over months, with better safety than legacy options (e.g., next-gen motilin/ghrelin agonists, better-studied 5-HT4 strategies).
2. Endotyping and biomarkers: we need to stop treating all gastroparesis as one disease. Clinical, physiologic, and microbiome/omic signatures that predict who benefits from which therapy (drug vs G-POEM vs GES) would transform care.
3. Patient-centered trials: larger, longer RCTs that prioritize validated symptom and quality-of-life outcomes, include nutritional endpoints, and reflect real-world medication confounders.
Our guideline intentionally highlights these gaps to hopefully catalyze better trials and smarter referral pathways.
