Sonali Paul, MD, once thought she was an anomaly in the world of medicine. “As I was going through training, I didn’t think others like me existed, a gay South Asian transplant hepatologist. I certainly didn’t have mentors that looked like me. I didn’t have anyone to look up to,” she said.
Fighting to promote health care equity in the LGBTQI+ population has been a cornerstone of her career. As cofounder and an executive board member of Rainbows in Gastro, a sexual and gender minorities affinity group that builds community among LGBTQI+ medical trainees and physicians in gastroenterology, Dr. Paul often goes into the community to promote open discussions about health equity in sexual and gender minority populations.
“Our mission is CHARM: community, healing, advocacy, research, and mentorship,” said Dr. Paul, a transplant hepatologist with the University of Chicago Medicine with a specific niche within fatty liver disease and obesity medicine. She serves as an associate program director for the Internal Medicine Residency Program specifically for diversity, equity, and inclusion.
In 2022 she received the University of Chicago’s Department of Medicine Diversity Award.
Dr. Paul has worked to establish policies such as documenting preferred gender identity of patients in electronic medical records and using pronoun cards on ID badges to make LGBTQI+ patients more comfortable. Rainbows in Gastro has shown trainees they can be open about their sexual orientation and gender identity without fear of retribution. “I’ve had medical students and residents come to me and say they were going to go into endocrine or some other field because they thought it was more gay friendly, until they saw our group and the work we’re doing,” Dr. Paul said.
In an interview, she talks more about her two key passions: reducing disparities and promoting health equity.
Q: You presented “Embrace the Rainbow: Creating Inclusive LGBTQ+ Spaces in Medicine” at the University of Chicago Medicine Grand Rounds. What were some of the key takeaways of that presentation?
Dr. Paul: One is education. Knowing the history of the LGBT community and how marginalization and discrimination affects the individual coming into that clinic is important. Having little things like pronoun badges or a rainbow flag, having nondiscrimination policies that include sexual orientation, gender identity that are displayed in the clinics, are very small things that seem almost trivial to some people. But I can tell you for myself, it matters if I walk into a door and there’s a rainbow flag there. I feel immediately safer.
Q: What are your hopes and aspirations for the field of GI moving forward?
Dr. Paul: I didn’t learn about social determinants of health in medical school, but more and more I think we’re starting to pivot and really look at those things. I hope GI and hepatology continues to do that.
For me, it’s looking at everything through a health disparities lens, seeing the health disparities across communities and finding solutions to mitigate them. How do we get people access to transplant for all our patients, and really examining the social determinants of health in the health care we provide?
Q: Your clinical focus has been on nonalcoholic fatty liver disease. Can you tell me how you got interested in that area of medicine?
Dr. Paul: There’s been a name change for the disease itself. It’s now metabolic dysfunction-associated steatotic liver disease (MASLD). I got interested from an obesity medicine perspective. I thought the liver pathology was interesting but I wanted to approach it from a different kind of perspective and not just focus on the liver, but also the metabolic factors.
I practice from that kind of lens: Looking at a lot of the metabolic comorbidities that happen with fatty liver disease to help patients with weight loss.
Q: What do you think about the new weight loss drugs?
Dr. Paul: I think they’re very effective. They’re obviously very popular. Weight loss is a really hard thing and I think they are really changing the game. A newer one that was just approved, tirzepatide (Zepbound, Lilly) resulted in up to 20% body weight loss. I think if there’s a medicine that we can give to avoid surgery for some people, I think that’s great. I think what is quite disheartening is insurance access to the medications.
Q: Is there any type of research you’re doing in this area right now?
Dr. Paul: I’m interested in the changes in fatty liver with gender-affirming hormone therapy with estrogen and testosterone, an area that’s never been studied.
Q: Describe how you would spend a free Saturday afternoon.
Dr. Paul: With my wife, my 9-year-old son, and two dogs. One of our favorite places to go is the Lincoln Park Zoo. We go there, especially over the summer, sometimes every week just to walk around. And, my son loves animals. Or, play with our dogs.

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.
