How ESG works – a safe and effective method for weight loss
ESG is a safe and recognized method used worldwide to help people achieve weight loss. Using an advanced endoscopic suturing system, the volume of the stomach is reduced from the inside – without any external surgical incisions.
This means that you can eat less and feel fuller faster, while your digestive function remains intact. The treatment is minimally invasive, resulting in a shorter recovery time and lower risk compared to traditional obesity surgery.

Could this be the solution you've been looking for?
- ESG (Endoscopic Sleeve Gastroplasty) at Kalbakkenklinikken is a gentle alternative for weight loss that is performed without external incisions, intestinal bypasses, or permanent anatomical changes to the stomach. This makes the treatment less invasive compared to traditional obesity surgery.
- One of the biggest advantages of ESG is the short recovery time, which allows patients to return to their daily lives more quickly. Compared to procedures such as gastric bypass or surgical sleeve, ESG carries a significantly lower risk of complications.
- Studies have shown that ESG causes fewer side effects and has a lower probability of serious complications such as leaks and infections. In addition, natural stomach function is preserved since no part of the stomach is removed. This means that the digestive process functions normally, making it easier to maintain a balanced nutritional intake without the need for lifelong vitamin supplements.
- The effectiveness of ESG has been well documented in clinical studies, which show that patients can achieve weight loss of up to 25% of their total body weight. The results also show that weight loss can be maintained for at least five years, making ESG a reliable and lasting option for those who want a safe and effective method of weight reduction.
Why ESG is groundbreaking
-
Safer risk profile
ESG is a minimally invasive procedure that increases patient safety and reduces the risk of complications. -
Long-term effect without surgical removal
Instead of removing parts of the stomach, ESG "tucks" the stomach back inside – which can also be reversed or adjusted if necessary. -
Reversible and adjustable
Should there be any changes in health status or a need for adjustment, the procedure can be adjusted endoscopically. -

Questions and answers
How much weight can I expect to lose?
Most people can expect to lose 20-25% of their total body weight during the first year, provided they follow the dietary and exercise recommendations. Some people achieve even greater weight loss.
How quickly will I recover after the procedure?
You will go home on the same day as the procedure. Most people are back to light activity within a few days.
Is ESG the right choice for me?
If you have a BMI over 29 and have not succeeded with traditional methods of weight loss, ESG may be an effective alternative. Assessment is made on an individual basis.
Is this safe?
Yes. ESG is performed without surgical incisions and has a very low risk of complications compared to traditional obesity surgery. The procedure is well established internationally.
Is the weight loss permanent?
Yes, studies show that weight loss can be sustained for at least 5 years – provided that you follow dietary and lifestyle advice. ESG provides a more lasting feeling of satiety and helps you establish new habits.
What happens if I gain weight again?
We offer revision procedures for previous gastric bypass and sleeve surgeries, as well as follow-up care for ESG patients.
Does it cost a lot?
Price from NOK 94,000, including surgery and 1.5 years of follow-up. We offer installment plans and flexible solutions for self-paying patients.
Will I have scars after the procedure?
No. ESG is completely endoscopic—that means no external incisions and no visible scars.
Will I have to take vitamins for the rest of my life?
No. ESG preserves the natural function of the stomach and intestines, so you avoid lifelong vitamin treatment as with surgical procedures.
Can ESG be done multiple times, if necessary?
Yes. In many cases, ESG can be repeated or adjusted if necessary. It is a flexible and reversible method.
Who is ESG suitable for?
ESG is suitable for adults with a BMI over 30 who want to lose weight without surgery – especially those who have tried diet and exercise without lasting results.
