FAQ
Most Popular Weight Loss Questions
Am I a candidate for weight loss surgery?
If you’ve been struggling to lose weight, bariatric surgery may be the most effective way to achieve lasting results and improve your health. Most candidates meet certain guidelines related to weight, BMI, or health conditions — but the best way to know? Take our “Am I a Candidate?” Quiz
What kind of results can I expect from surgery?
Most patients lose about 1/3 of their total body weight-often improving or resolving conditions like diabetes, sleep apnea, and hypertension. Long-term success depends on ongoing support and healthy lifestyle changes, which is why Eviva offers continuous aftercare.
Should I try weight loss injections before having weight loss surgery?
Weight loss injections (like GLP-1 medications such as semaglutide / Ozempic / Wegovy or tirzepatide / Mounjaro / Zepbound) help control appetite and blood sugar, leading to gradual weight loss—typically around 10-15% of body weight with ongoing use. They are non-surgical but often require long-term use and can be costly without insurance. Unfortunately, the majority of patients gain weight back after stopping medications.
Bariatric surgery (such as gastric sleeve or bypass) is a more permanent option that physically alters the digestive system to limit intake and/or absorption. It typically results in more significant weight loss (30–35% of total body weight), especially for those with higher BMIs or obesity-related health conditions.
In short: Injections are less invasive but slower and often temporary; surgery is more effective long-term but involves recovery and commitment.
Will I gain the weight back after weight loss surgery?
The majority of our patients are able to maintain their weight loss. About 1 in 4 may regain some weight, but it’s uncommon for anyone to return to their highest weight. Surgery is a powerful tool, not a cure, and it works best when combined with long-term support.
We’re aiming for healthy, happy, and sustainable. And we’re with you every step of the way.
Will insurance cover my weight loss surgery?
At Eviva, we accept various insurance plans for weight loss surgery, including Aetna, Cigna, Premera, Regence, United Healthcare, and others. Coverage varies by policy, so it’s essential to verify your benefits. Our experienced Insurance Coordinator can assist you in navigating this process.

What’s the difference between gastric sleeve, gastric bypass and endoscopic sleeve?
All these options are excellent weight loss tools that reduce the volume of your stomach to aid with portion control and calorie deficit weight loss.
- Gastric sleeve (VSG): Removes part of the stomach to limit how much you can eat and reduce hunger hormones.
- Gastric bypass: Reroutes the digestive system to reduce calorie absorption and improve blood sugar control.
- Endoscopic sleeve gastroplasty (ESG): A non-surgical procedure that reshapes the stomach using a camera and sutures—no incisions or hospital stay needed.
Each procedure offers different benefits depending on your health and goals. Talk to our team to find out which is right for you.
