It has been almost eight months since the operation, and it has done everything I hoped. It is a huge victory that I made that decision for myself.
What did Nadja Engsig say about her operation?
Nadja Engsig became known to Danish viewers through TV 2 documentaries about her life with binge eating disorder, and later through the programmes “Nadjas farvel til de 170 kilo”. In an interview with SE og HØR published on 6 May 2021, the magazine reported that she had a gastric bypass in August 2020, when she weighed almost 180 kilograms.

WhatsAppAbout the result she said: “It has been almost eight months since the operation, and it has done everything I hoped. It is a huge victory that I made that decision for myself.”
She also explained an unusual choice. Already before the operation she decided that she would not be weighed or measured, and that the number on the scale would not be the yardstick for whether the operation was a success. She said she still holds on to that, and that she does not want to know how much she has lost. She was honest that the road had not been easy: it had been very hard at times and made her doubt herself, even though she could feel it was the right thing for her.
That is all we rely on here. We do not add medical details she did not share and do not guess at the method beyond what was reported. The explanations below describe gastric bypass and bariatric surgery in general, not her treatment.
Why her openness matters
Most public stories about weight-loss surgery are told through numbers: kilos before, kilos after. Nadja Engsig deliberately told hers without them. She has spoken openly about binge eating disorder, and she said that stepping on the scale again could feed the eating disorder she has worked hard to treat.

Her point was that she did not have the operation in the belief that being thinner would automatically make her happier; her reasons were different, and she said she often felt alone with that approach.
That message is useful for anyone considering bariatric surgery. The operation is a tool that changes how much a person can eat and how the body handles food. It does not replace treatment of an eating disorder, and it works best when the psychological side is taken seriously before and after surgery. It is also a reminder that success can be measured in quality of life, energy and everyday freedom, not only in kilograms. According to the magazine, she now finds it much easier to go for walks and play with her two dachshunds.

How gastric bypass and other bariatric operations work today
Modern bariatric operations are laparoscopic: the surgeon works through four small punctures of 5–15 mm rather than a large incision. In a Roux-en-Y gastric bypass a small stomach pouch is created and connected directly to the small intestine, so food bypasses most of the stomach and part of the intestine. People feel full sooner, eat less and absorb fewer calories. A sleeve gastrectomy removes most of the stomach and leaves a narrow tube.
There are also mini gastric bypass (one-anastomosis) and SADI-S for very high BMI.
What is changed
- Sleeve gastrectomy
- Most of the stomach is removed
- Gastric bypass

- Sleeve gastrectomy
- BMI of about 35–45
- Gastric bypass
- BMI over 45–50, often with type 2 diabetes
Average loss of excess weight
- Sleeve gastrectomy
- 60–70%
- Gastric bypass
- 75–85%
Vitamins afterwards
- Sleeve gastrectomy
- As advised by the doctor
- Gastric bypass
- Lifelong vitamins and minerals
Price at City Medical Centre
- Sleeve gastrectomy
- $3,600

Gastric bypass is often called the “gold standard” for patients with a high BMI and type 2 diabetes. Which operation fits a particular person is decided by the surgeon after tests and a consultation.
Who is it for, and how to prepare
Bariatric surgery is usually considered when:
- the body mass index (BMI) is above 40;
- the BMI is above 35 and there are serious weight-related conditions;
- in some cases with a lower BMI, if non-surgical approaches have not worked.
Preparation includes blood and urine tests, biochemistry, an HbA1c test and coagulation tests, as well as consultations with a general practitioner, an endocrinologist, a cardiologist, a psychiatrist and, for women, a gynaecologist. The psychiatric consultation is not a formality: as Nadja Engsig's story shows, eating behaviour and the reasons behind the decision matter as much as the operation itself. Patients are advised to cut fast carbohydrates and fats two to four weeks before surgery and to stop smoking a month before.
What recovery looks like
Patients are usually up and walking on the first day and stay in hospital for one to five days. The diet moves in stages over one to two months, from liquid to soft to normal food. Office work is usually possible after two to four weeks and physical work after about a month and a half.
Swimming is allowed after about 30 days, and long trips are best planned no earlier than a month after surgery. After a gastric bypass vitamins and minerals are needed for life. Pregnancy is recommended no earlier than 12–18 months after the operation, and the final result is assessed after one and a half to two years. The timeline below shows the usual stages.

How recovery after a gastric bypass usually goes
- Day of surgeryLaparoscopic operation through four small punctures under general anaesthesia.
- Day 1Patients get up and walk; drinking starts in small sips.
- Days 1–5Hospital stay, depending on the operation and how you feel.
- Months 1–2Staged diet: liquid, then soft, then normal food; swimming after about 30 days.
- Months 1–12The fastest weight loss, lifelong vitamins and regular follow-up with the team.
- 1.5–2 yearsThe final result is assessed.

Frequently asked questions

How much weight has Nadja Engsig lost?
She does not know and does not want to know. Before the operation she decided not to be weighed or measured, so that the scale would not be the yardstick for success.
