We aim to highlight the importance of overall health first and foremost, through careful nutrition education, guided lifestyle plans, weight loss medications, and endoscopic bariatric techniques as part of a comprehensive weight loss program.

Our goal is to help you both achieve and sustain healthy weight loss through an evidence-based approach for long term success.

Are you looking to lose weight safely and effectively? Our services are tailored to meet your specific needs. We perform a comprehensive analysis of your medical records, health status, and weight loss goals to determine the best procedure for you.

Non-surgical procedures

Weight loss is a common goal that has evaded many patients despite years of numerous diet and exercise regimens. We combine endoscopic procedures with dietary changes, weight loss medications, and consistency to help achieve results. Non-scale wins also include improved sleep and energy, reduced joint pain, reversal of diabetes, hypertension, high cholesterol, Gerd, and so much more.

*Individual results may vary.

Dr. Laster is awesome. She is an expert in her field. I researched several doctors before I made my decision to go with Gut Theory Total Digestive Care.
Dr. Laster explained the ESG procedure in great detail. I was immediately put at ease. My after care was top notch, the IV the next day was a godsend. Dr. Laster called everyday for a week to make sure everything was going according to plan. I can’t say enough about the nutrition plan she provides and the aftercare. Dr. Laster is dedicated to providing patients with all of the tools for the weight loss. I am so thankful to have found Gut Theory.

I feel like all my adult life I struggled to maintain a healthy weight. In my 20’s I would spend hours in the gym every other day. But as my life changed and my family grew I started exercising less and less. I weighed myself one day and said that enough (I don’t eat terribly, no candy soda etc) so I decreased the amount of food bought a food scale, only ate between the hours of 8am and 4pm for 6 weeks and you know how much weight I lost? Not one pound. I knew I needed professional help. With a little research I found Dr. Laster and her team. Her office always has street parking and the tele-visits are even more convenient. If you’re remotely close to the DC area I would recommend stop dieting and giving Dr. Laster a call. She changed my life!
