More Than Weight Loss
Bariatric surgery doesn't just reduce weight - it triggers a complete metabolic reset that reverses biological aging at the cellular level.
Inflammation Crash
CRP, IL-6, and other inflammatory markers plummet after surgery - these are core GrimAge components that drive biological aging.
Metabolic Reset
Insulin sensitivity improves dramatically, often reversing type 2 diabetes. Leptin and PAI-1 normalize - both measured by GrimAge.
Epigenetic Reprogramming
The massive metabolic shift actually changes DNA methylation patterns - your cells begin expressing younger gene profiles.
Why Track GrimAge Around Surgery?
You're making a life-changing investment in your health. GrimAge lets you quantify just how much younger your body becomes.

Frequently Asked Questions
How much biological age reversal can I expect?
Studies show average GrimAge reductions of 5-8 years within the first year after surgery. Results vary based on starting weight, amount lost, and individual factors. Some patients have seen even larger improvements.
Does the type of surgery matter?
All bariatric procedures show biological age improvements. Some research suggests gastric bypass may produce slightly larger effects than sleeve gastrectomy, but the differences are modest. We track all surgery types to compare outcomes.
What if I regain some weight?
Weight regain is common and doesn't necessarily mean you lose all biological improvements. Some epigenetic changes appear to persist. Continued monitoring can show you exactly where you stand and motivate maintenance behaviors.
I already had surgery - can I still join?
Yes! If you're within 3 months post-surgery, you can join the main study. If it's been longer, we have a maintenance cohort that tracks long-term outcomes. We can also compare your current GrimAge to expected pre-surgery levels.
Is this covered by insurance?
Epigenetic testing is not typically covered by insurance. However, study participants receive significantly discounted testing rates through research funding. We're working to demonstrate the clinical value of pre/post testing to support future coverage.
