Obesity may be an important cause of rectal cancer


Obesity may be an important cause of rectal cancer.  Not only tobacco and alcohol, it is also the “culprit” of rectal cancer, but unfortunately most of them ignore it.

Obesity may be an important cause of rectal cancer

Food is the main source of nutrition for the human body. After the food enters the human body, it needs the help of digestive organs such as the stomach and intestines to be transformed into nutrition and provide energy for the human body.

It can be said that the human body will be healthier only if the function of the gastrointestinal tract is healthy.


In recent years, the incidence of gastrointestinal tumors has been increasing, including rectal cancer.

This phenomenon has a lot to do with unhealthy lifestyle habits. For example, a lot of smoking and drinking will stimulate the intestines and increase the risk of rectal cancer.

When it comes to the “culprit” of rectal cancer, it is not tobacco and alcohol, but another reason.


“Obesity” can increase the risk of rectal cancer

Obesity is one of the known risk factors for rectal cancer.

In recent years, young obese people who exercise less, eat more, and sit for a long time have gradually become a high-risk group for rectal cancer.

This is because obese people tend to eat high-fat and high-cholesterol foods in their diets, and they don’t like exercise in life, which can easily increase the burden of digestion and affect the normal digestive function of the intestine. Fat metabolites can also be used. The formation of carcinogens increases the risk of cancer.


In addition, obese people consume less dietary fiber, and dietary fiber can promote intestinal peristalsis, and promote the digestion and decomposition of fat. If dietary fiber is insufficient, it is easy to cause constipation and cause harmful substances to interact with the intestinal mucosa for a long time. Exposure has become a potential risk factor for rectal cancer.

According to clinical statistics, most patients with rectal cancer are obese people, especially those who accumulate a lot of fat in the waist and abdomen, who are more likely to develop rectal cancer.

Therefore, obese people should pay attention to their waist-to-hip ratio. If the waist-to-hip ratio of men is greater than 0.9, and the waist-to-hip ratio of women is greater than 0.85, special attention should be paid.


How to prevent rectal cancer in life?

1. Adjust the diet

Too much high-fat, high-calorie food and too little dietary fiber intake can cause obesity and increase the risk of bowel cancer.

It is recommended that everyone should focus on low-fat and low-sugar foods in their lives, eat less fried, barbecued and other foods, increase the intake of vegetables and fruits, and supplement the body with sufficient dietary fiber and vitamins.

2. Develop healthy living habits

To prevent rectal cancer, you should exercise more in your life, especially for obese patients, you should insist on exercising. Not only can you exercise, but you can also lose weight and reduce the risk of intestinal cancer.

At the same time, you must quit smoking and drinking in your life, pay attention to regular work and rest, and avoid staying up late. Emotions also have a great impact on gastrointestinal health, and maintaining an optimistic and positive attitude is more conducive to intestinal health.

3. Regular physical examinations to treat precancerous lesions

Ordinary people should insist on regular physical examinations in order to find intestinal diseases in time and deal with them in time. People at high risk of bowel cancer should go to the hospital to be screened for bowel cancer on a regular basis.

If you suffer from ulcerative colitis or intestinal polyps, you should treat them in time to reduce the incidence and mortality of intestinal cancer.


Rectal cancer can be said to be a “lifestyle disease”. Frequent smoking, drinking, and irregular diet are important causes of rectal cancer. In particular, “obesity” greatly increases the risk of intestinal cancer.

Therefore, everyone should develop a healthy lifestyle in life, stay away from tobacco and alcohol, exercise more, and obese people should actively lose weight and maintain a healthy body shape. Coupled with regular physical examinations, I believe that we can better stay away from bowel cancer!
