Study finds relationship between obesity and cancer risk, bariatric surgery can reduce cancer risk, true or false?

Obesity has always been a problem that plagues everyone. I followed so many weight loss tutorials on the Internet to learn to lose weight, but the effect was not ideal. How many times I have the mentality of “let it go” . However, if you really keep getting fat like this, it will not only affect your body and appearance, but also your health, because the degree of obesity will affect your health, which is recognized by the medical profession.

What is the relationship between obesity and cancer risk?

3.9% of new cancers linked to overweight, obesity , including the well-known breast cancer, pancreatic cancer, colorectal cancer and so on. Therefore, being able to control your weight well and not let your body become overweight actually reduces your cancer risk in itself.

In the major chronic diseases and cancer prevention guidelines, “weight control” is also regarded as one of the healthy lives, but when it comes to losing weight, people The first thing that comes to mind is exercise, followed by taking medicine.

The former of these two methods is not easy to adhere to, and the latter has relatively large side effects. Therefore, people have always been on the road to losing weight It didn’t go well. So, is there a more effective and safe method?

Bariatric surgery reduces cancer risk, study finds32 %

The experiment included more than 30,000 obese patients, of whom 5053 underwent bariatric surgery. The average body weight of the patients who underwent surgery dropped by 55 catties, and the incidence of cancer also decreased.

Those who did not undergo weight loss surgery (25,265) lost less weight after 10 years, and 780 of them developed cancer. Meanwhile, the study compared two types of bariatric surgery and found they had little effect on tumors. In other words, patients undergoing bariatric surgery, no matter which one they choose, can reduce their own cancer risk by 32%.

What is the difference between the two types of bariatric surgery, sleeve gastrectomy and gastric bypass surgery?

sleeve gastrectomy

This surgery has been developed for more than 20 years, but it was rarely heard of before. In recent years, it is because many celebrities have had their stomachs cut that everyone is familiar with it. The person undergoing this operation is not ordinary obese, but very, very obese. The greater curvature of the stomach is removed by surgery, leaving only a small part of the stomach that connects with the small intestine, which is shaped like a banana.

Gastric bypass surgery

Normal digested food enters the stomach, and protein can be fully utilized , and now a gastric sac is placed in the stomach through surgery, food goes directly to the end of the small intestine from this thin channel, the path is shortened, digestion avoids the gastric sac, and the original sac gradually becomes empty.

The advantage is that the effect of weight loss is good, and it can also help control sugar, but there are also disadvantages. It is precisely because the food intake is reduced, so It is easy to be deficient in certain nutrients.

These two methods have good results, but we must also remind everyone that not everyone is suitable, mainly for< strong>Diabetics or very obese people, if your BMI index is just over 28, weight loss surgery is not recommended.

If you justwant to keep slim, don’t just do surgery , over time it can have side effects.

YouIs it really fat or fake fat? Use the formula to calculate and you will know

BMI=weight (kg) divided by height (m) divided by height (m)

18.5-23.9 normal

24-27 overweight

≥28 obese

< span> You can use your height and weight to calculate, which grade you are in now, maybe you are not as fat as you imagined.

For example, if you are 173cm tall and weigh 240kg, the formula is 120/1.73/1.73≈40, so your BMI is 40, which means you are very obese.

If the height is 160 cm and the weight is 110 catties, I feel very fat, but through calculation, I find that the BMI index is 21.48, and I don’t have diabetes. Gastrectomy cannot be performed at this time, and the risk of malnutrition is very high.

In the final analysis, gastric incision is an operation, as long as it is an operation, there are certain risks and possible complications, so you should think twice Then go

Because the volume of the stomach becomes smaller and the pressure changes, gastric acid tends to go up when the patient lies down or relies on it With reflux, you will feel a little heartburn and want to vomit, but not everyone is like this, and it has something to do with the doctor’s resection technique, the patient’s physique, and the food you eat. Eat less sweets, greasy food, and sour food at ordinary times, and you can eat semi-liquid food.

In addition to gastric reflux, gastric leakage may also occur.Experienced doctors can reduce the risk of gastric leakage, but cannot completely avoid it, because Stomach acid is very corrosive, and there is a gap in the resection site, and there is a small chance of it happening after suturing, and infection will occur at that time.

So, when you choose, you should consider many aspects, whether your physical condition is so serious that the only way to go is stomach surgery , Whether you can accept the possible complications well, whether the quality of life and the body can get greater benefits from the operation.
