DDW 2026 highlights colorectal cancer screening, GLP-1 research, and Crohn’s disease therapy

Asma Shaukat, MD, Professor of Medicine at NYU Grossman School of Medicine and outgoing Chair of the Clinical Practice Section for the AGA Council, discussed 13-year Nordic trial findings showing reduced colorectal cancer incidence with colonoscopy screening, along with emerging data on GLP-1 therapies in fatty liver disease and cirrhosis. Bruce Sands, MD, Chief of Gastroenterology and Professor of Medicine at the Icahn School of Medicine at Mount Sinai, presented findings from the DUET-CD study evaluating combination therapy in Crohn’s disease.

ACOG 2026 annual meeting: Key trends in menopause, perinatal mental health, and maternal-fetal cannabis outcomes

Dr. Nanette Rowley, General Program Chair for ACOG 2026 (Washington, DC), highlighted strong engagement across sessions on menopause, emergency obstetrics, and perinatal mental health, alongside robust well-being programming. The first-place research award (McClain et al., Henry Ford Health) revealed diagnostic imprecision in intra-amniotic infection, with poor concordance between clinical criteria and placental pathology underscoring the need for standardized protocols. A Penn State study by medical student Arisha Tariq found 45% of THC-exposed neonates required NICU admission, citing prematurity, respiratory distress, and neonatal abstinence syndrome as key concerns.

Integrating oral GLP-1 pathways into obesity care: clinical decisions beyond initiation

As obesity care continues to evolve, clinical focus is shifting from initiating therapy to managing obesity as a long-term, relapsing condition. Recent advances in oral glucagon-like peptide-1 (GLP-1) receptor agonist development reinforce this shift, prompting clinicians to consider not only whether to use pharmacologic therapy, but how it can be integrated into sustained, multidimensional care plans over time.

GLP-1 receptor activation influences appetite regulation, satiety signaling, and metabolic pathways central to obesity pathophysiology. Oral formulations demonstrate that these mechanisms can be engaged through daily administration, expanding how clinicians think about treatment design and long-term engagement. This evolution brings renewed attention to clinical integration—how pharmacologic therapy aligns with behavioral strategies, lifestyle interventions, and ongoing monitoring rather than functioning as a stand-alone solution.

Patient selection and adherence remain central considerations in long-term obesity management. Functional factors such as daily dosing routines, gastrointestinal tolerability, and treatment fatigue—as well as emotional factors including expectations, motivation, and prior weight-loss experiences—may influence sustained use and outcomes. These considerations highlight the importance of shared decision-making and regular reassessment as patient needs and priorities evolve.

Rather than viewing therapy choice as a single decision point, many clinicians are approaching obesity care as a dynamic process that requires adjustment over time. Evidence-based strategies increasingly emphasize structured follow-up, realistic goal-setting, behavioral support, and coordinated, multidisciplinary care. Within this framework, oral GLP-1 approaches may offer flexibility across different phases of treatment, including escalation, stabilization, or maintenance.

What factors most influence how you select patients for long-term pharmacologic obesity therapy?As oral GLP-1 options enter clinical practice, what adherence challenges or integration considerations will most shape how you incorporate them into comprehensive obesity care?

case study

Patient Background:

Mr. C is a 52-year-old male with a BMI of 37 kg/m² and a 10-year history of obesity with multiple prior attempts at sustained weight loss through calorie restriction and exercise.

Comorbidities include hypertension (amlodipine 10 mg), dyslipidemia (atorvastatin 40 mg), prediabetes (HbA1c 6.2%), and obstructive sleep apnea managed with CPAP. He is a non-smoker. Family history includes paternal myocardial infarction at age 58. He is motivated for pharmacologic intervention and has enrolled in a structured lifestyle program.

Assessment & Diagnosis:

Waist circumference: 116 cm. BP: 138/86 mmHg. Fasting glucose: 108 mg/dL. LDL-C: 118 mg/dL.read more

He is an appropriate candidate for chronic weight management therapy. Treatment selection was guided by shared decision-making, cardiometabolic risk profile, prior weight-management history, and patient preference.

The care team initiates a once-weekly subcutaneous GLP-1 receptor agonist with gradual dose escalation over 16–20 weeks to improve tolerability.

In the STEP 1 trial (n=1,961), participants treated with semaglutide achieved a mean weight loss of 14.9% vs 2.4% with placebo at 68 weeks (p<0.001).

Common adverse effects discussed with the patient include nausea, vomiting, diarrhea, and constipation, particularly during dose escalation.

Obesity is increasingly recognized as a chronic inflammatory condition associated with altered metabolic signaling, insulin resistance, and systemic health complications. Growing evidence supports the importance of early, sustained approaches to long-term weight management.
