About Jeremias C. Tan, MD

Since joining Gastro Health in 2006, Dr. Tan has served Northern Virginia as an Advanced Endoscopist. He is a leader and frequently the first to introduce new therapies that reduce residual health risks for patients.

Over the past several years, Dr. Tan began to notice an increase in patients suffering from obesity-related GI issues including gastroesophageal reflux disease (GERD). Left untreated, GERD can lead to more significant health issues such as barrett’s esophagus and esophageal cancer. Dr. Tan developed a special interest in the causal relationship between GERD-related disorders and obesity. 

 Dr. Tan also participates in Grand Rounds at Inova Fairfax Hospital. He has served as Chief Medical Resident and authored multiple articles during his fellowship and has presented at national meetings.

Dr. Tan performs multiple endoscopic weight-loss procedures including: Weight-Loss Gastric Balloons, Endoscopic Sleeve Gastroplasty (ESG), Gastric Sleeve Revision, and Revision of Roux-en-Y Gastric Bypass.
