About

Gut Theory Total Digestive Care operates as a comprehensive gastroenterology and functional medicine practice in Washington, DC, under the direction of Dr. Janese Laster, a board-certified physician in internal medicine, gastroenterology, and obesity medicine. The clinic addresses digestive disorders, metabolic dysfunction, and weight management through an integrated approach that examines the connections between gut health, hormonal balance, and systemic inflammation. Dr. Laster's triple board certification allows the practice to treat conditions ranging from irritable bowel syndrome and inflammatory bowel disease to insulin resistance and hypertension within a single care model, eliminating the fragmented approach common in conventional gastroenterology.

The clinic's treatment protocols extend beyond standard endoscopic procedures to include peptide therapies targeting metabolic health and tissue repair. Patients receive access to GLP-1 receptor agonists for weight management and glycemic control, BPC-157 for intestinal barrier restoration in cases of leaky gut syndrome, and thymosin alpha-1 for immune modulation in autoimmune gastrointestinal conditions. The practice combines these peptide interventions with comprehensive stool microbiome analysis, food sensitivity testing, and continuous glucose monitoring to create data-driven treatment plans. Nutritional protocols address specific deficiencies identified through laboratory work, with particular attention to vitamin D, B12, and iron levels that commonly affect patients with malabsorption disorders.

Dr. Laster completed her gastroenterology fellowship at Georgetown University Hospital and maintains active hospital privileges at Medstar Washington Hospital Center. Her clinical focus includes the management of complex cases where digestive symptoms intersect with metabolic syndrome, utilizing both pharmacologic interventions and lifestyle modification programs. The practice employs registered dietitians who work directly with patients on elimination diets, low-FODMAP protocols, and anti-inflammatory meal planning tailored to individual diagnostic findings. Patients with conditions such as small intestinal bacterial overgrowth (SIBO), non-alcoholic fatty liver disease, and gastroparesis receive coordinated care that addresses both symptom management and underlying pathophysiology.

New patients at Gut Theory Total Digestive Care undergo an initial consultation lasting 60-90 minutes, during which Dr. Laster reviews complete medical history, current symptoms, previous diagnostic testing, and treatment responses. The practice orders baseline laboratory panels that assess inflammatory markers, metabolic function, nutrient status, and hormonal balance before developing individualized treatment protocols. Follow-up visits occur at intervals determined by condition severity and treatment response, with most patients seen monthly during active intervention phases. The clinic provides secure patient portal access for lab result review, prescription management, and direct messaging with clinical staff between scheduled appointments.

Gut Theory Total Digestive Care serves patients throughout the Washington, DC metropolitan area, including residents of Maryland and Virginia who travel to the District for specialized gastroenterology care. The practice accepts most major insurance plans for covered services, though certain functional medicine testing and peptide therapies may require out-of-pocket payment. Dr. Laster's approach emphasizes patient education, providing detailed explanations of diagnostic findings and the scientific rationale behind each treatment recommendation, allowing patients to make informed decisions about their care trajectory.
