Janelle Woodburn | Before and After Weight Loss Surgery
“Today marks 19 months since my VSG surgery. I haven’t lost weight this month and forgot to measure, but I’ll get back on track by measuring on Feb 18th. I’ve been stress eating unhealthy foods, but now prioritize my health and want to consistently do things that contribute to my goals and progress, even on my worst days.”

~Janelle Woodburn, USA

Leaann Mungai | Before and After Weight Loss Surgery
“2 years ago, I had gastric bypass surgery with Dr. Lopez and went from 300+ lbs to 135 lbs. It took work and dedication, but it was worth it. The healing process had emotional ups and downs, but I stayed motivated by looking at others’ progress and kept a food journal. I’m healthier and happier than ever, and Dr. Lopez says I’m doing great.”
