Dr. Alexander Shapsis, MD

Dr. Alexander Shapsis, MD operates Atlantic Gastroenterology in Brooklyn, NY, a practice established in 2007 that integrates gastroenterology with evidence-based weight management through the EndoSlim Clinic. Board-certified by the American Board of Internal Medicine, American Board of Gastroenterology, and American Board of Obesity Medicine, Dr. Shapsis brings a multidisciplinary approach to patients seeking non-surgical solutions for obesity and metabolic health. The practice serves New York residents through telehealth consultations, allowing patients across the state to access specialized care without the need for in-person visits for weight management protocols.

The EndoSlim Clinic within Atlantic Gastroenterology offers GLP-1 receptor agonist therapy using semaglutide and tirzepatide for patients with obesity or weight-related metabolic conditions. These peptide medications work by regulating appetite, slowing gastric emptying, and improving insulin sensitivity, providing pharmacological support for sustainable weight reduction. Dr. Shapsis evaluates each patient's medical history, current medications, and weight loss goals to determine appropriate candidacy for peptide therapy. Treatment protocols include dosage titration schedules, monitoring for gastrointestinal side effects, and coordination with patients' existing healthcare providers when managing comorbid conditions such as type 2 diabetes or hypertension.

Dr. Shapsis's triple board certification positions him to address the complex interplay between gastrointestinal health and metabolic disease. His gastroenterology background informs his approach to managing the GI side effects commonly associated with GLP-1 therapies, while his obesity medicine certification ensures treatment aligns with current clinical guidelines for long-term weight management. Patients benefit from a provider who understands both the digestive system's role in nutrient absorption and hormone regulation, and the behavioral and physiological factors that contribute to obesity. This integrated expertise allows for more comprehensive care than weight loss programs led by providers without gastroenterology training.

Telehealth consultations at Atlantic Gastroenterology begin with a detailed medical intake covering weight history, previous weight loss attempts, current medications, and any gastrointestinal symptoms. Dr. Shapsis reviews laboratory work including metabolic panels and thyroid function tests to rule out contraindications and establish baseline health markers. Patients receive education on proper medication administration, expected timelines for weight reduction, dietary modifications to enhance peptide efficacy, and strategies for managing common side effects like nausea or constipation. Follow-up appointments track progress, adjust dosing as needed, and address any concerns that arise during treatment. The practice's telehealth model provides flexibility for working professionals and those with mobility limitations while maintaining the clinical rigor of traditional in-office care.

Atlantic Gastroenterology's location in Brooklyn positions the practice to serve New York City's diverse population, with telehealth access extending to patients throughout New York State. The combination of Dr. Shapsis's gastroenterology expertise and obesity medicine certification creates a unique clinical environment where peptide-based weight management is informed by deep understanding of digestive physiology. Patients seeking medical weight loss with a provider who can address both metabolic and gastrointestinal dimensions of obesity treatment will find a clinically sophisticated approach at this established Brooklyn practice.
