With the rapid development of society, more and more people are too lazy to cook for themselves when they get home because of work pressure and other reasons and rely on take-out for a long time. But many people ignore that eating certain unhealthy take-out for a long time may damage gastrointestinal health, and even cause intestinal diseases. According to the survey, in recent years, the incidence of intestinal diseases in China is a linear increase in the trend, and the patients with such diseases are getting younger and younger.

26-year-old Ms. Li is a people tea lover, who loves life, cooks every day by herself, and pays attention to exercise. However, during a recent period, Ms. Li often experienced abdominal pain and diarrhea, which she thought was due to bad food, and didn't pay much attention to it. But after a week, the symptoms still did not see improvement, but also the symptoms of bleeding stools, so Ms. Li accompanied by her husband rushed to the hospital for examination.

After the colonoscopy, Ms. Li was diagnosed with early-stage colon cancer. Hearing the result, both of them were so scared that their legs were weak, and it was especially hard to accept it, but in the early stage of cancer, the doctor operated to remove it for her about a week after the diagnosis, and Ms. Li's body recovered relatively well after the operation. However, Ms. Li and her husband have been wondering why they still suffered from colon cancer when their family has been eating regularly and cooking by themselves.

During one of the checkups, the attending doctor heard Ms. Li say to her husband how the porridge she made today was not sweet at all. The doctor came over and asked, "Does Ms. Li like sweets in her daily life? Her husband said: not only like, simply addicted to sugar ah. The doctor told the couple that Ms. Li's colon cancer was most likely caused by excessive sugar intake.

Why would sugar cause bowel cancer? Can sugar cause colon cancer?

Sugar is a basic nutrient needed by the human body, whether it is for the brain, nervous system, or red blood cells, they all need glucose in the blood to provide energy. But in the early years, the World Health Organization (WHO) and the Chinese Nutrition Association have mentioned that the daily intake of sugar for ordinary adults should be limited to about 25g, with a maximum of 50g, and added sugar is prohibited in the food of children under 3 years old.

It turns out that as early as the 1980s, the market launched a lot of corn syrup-based drinks, but with the popularity of the drinks, the incidence of colon cancer has increased, and the trend of youth has also increased greatly. These problems attracted the attention of scientists at the time, and several experimental studies on sugar and colorectal cancer were carried out.

Experimenters fed healthy mice 400μL of 25% corn syrup every day, the amount is about a 300ml bottle of cola, which would not have affected their health. However, as time passed, after 8 weeks, the researchers found polyps of various sizes in the intestines of the mice, and most colorectal cancer is the evolution of intestinal polyps.

To further study, researchers extracted glucose and fructose from corn syrup separately and fed mice that had developed intestinal polyps with water, fructose, glucose, and fructose + glucose respectively for control experiments, and found that a daily intake of about 5g of fructose would saturate the small intestine with GLUT5, reaching the upper limit of absorption, and any excess energy would be absorbed by the polyps, accelerating their growth rate.

The growth rate of intestinal polyps in mice consuming fructose + glucose was also much higher than that in mice consuming glucose alone, leading to the conclusion that fructose can promote the growth rate of colorectal tumors. Moreover, it was found that increased blood sugar levels greatly increase the growth factors and inflammatory factors in the body, raising the incidence of intestinal polyps and increasing the risk of colorectal cancer. So what are the symptoms that indicate colorectal cancer in people's lives?

What are the symptoms that indicate colorectal cancer?

Colorectal cancer is one of the common malignant tumors in the gastrointestinal tract, including colon cancer and rectal cancer. According to the data survey of our cancer center, in recent years, the incidence of colon cancer among people aged 41-65 has been on a steep rise. Clinically, 90% of colorectal cancers are developed from intestinal polyps, and many people miss the best time for treatment due to polyps or not paying enough attention to the early stage of cancer, which greatly reduces the survival rate. Therefore, we must pay attention to the following symptoms when they appear in the body, which may be a reminder that something is wrong with the intestine

Abdominal pain and bloating

Many patients may experience mild abdominal pain in the early stage of colorectal cancer, and because the sensory nerves of internal organs are relatively slow to respond, sometimes they may not be able to express the exact location of the pain, which is mainly manifested as intermittent pain or continuous hidden pain. Some patients may also suffer from intestinal obstruction caused by tumor blockage.

When patients have symptoms of colorectal cancer combined with intestinal obstruction, they will have obvious symptoms of abdominal distension and abdominal cramps. Moreover, if the tumor is located close to the anal canal, it may also cause anal pain. For patients with sensitive intestinal tract and gastrointestinal diseases, once frequent abdominal pain, abdominal distension, and anal pain occur, they should seek medical attention in time.

Blood in stool

Blood in stool is a typical symptom of early-stage colorectal cancer, but many patients are easy to ignore it because the bleeding is not much in the early stage. And even if they see bleeding, they may be misdiagnosed as hemorrhoids, so how should people distinguish bleeding from colon cancer and hemorrhoids?

It is easy to distinguish from the color of the bleeding because intestinal cancer is bleeding in the intestine and the blood turns dark red or black after oxidation of intestinal fluid. And the higher the location of the tumor, the longer the blood stays in the intestine, and the darker the color of the blood.

In contrast, most bleeding caused by hemorrhoids is bright red, which may be caused by friction on the surface of the hemorrhoids, and the bleeding is less, mostly in the form of drops or jets, not mixed with the expelled stool, and mostly floating on the surface of the stool.

Abnormal bowel movements

Abnormal bowel movement is also a frequent symptom of many colorectal cancer patients. It is mainly reflected in the more frequent, unformed, and thin deformation of stool. The number of bowel movements may increase from once a day to 4-5 times a day, which is mainly caused by inflammation caused by tumor lesions and mucus secretion by the tumor itself, thus stimulating the intestinal mucosa, and with the development of tumor, the abnormal bowel movements will become more and more obvious.

The deformation and thinning of the stool of colon cancer patients are mainly due to the narrowing of the intestinal cavity as the tumor increases. However, long and thin stools are not all caused by colorectal cancer. If patients have these symptoms, they should seek medical treatment in time to determine the cause and achieve early detection and treatment.

Lose weight

According to clinical data, 30-50% of cancer patients in China have the symptom of losing weight, especially in the advanced stage of cancer. Especially for colorectal cancer patients, cancer tumors will damage the function of the intestinal tract, resulting in the inability to absorb nutrients better and making patients wasted.

Clinically, many colorectal cancer patients do not have very obvious symptoms in the late stage of cancer, and most of them only go to the hospital for medical checkups or late-stage cancer, and many of them are affected by missing the best treatment period, which reminds people that regular colonoscopy is very important.

Regular colonoscopy is important

Colonoscopy is also called electronic fiberoptic colonoscopy, which is a kind of endoscope. A colonoscopy is a process of passing a fiberoptic tube of 1cm diameter, bendable and with a camera with a cold light source in front of the tube diameter, through the anus into the intestine.

It can help diagnose more than 40 diseases such as intestinal polyps, colorectal cancer, and enteritis. Because the early symptoms of colon cancer are not very obvious, colonoscopy has become the main means of screening colon cancer and the gold standard for diagnosis.

And as early as 2000, the United States adopted mandatory colonoscopies for its citizens over the age of 50. According to 2017 data from the U.S. Bureau of Cancer Statistics, the male colorectal cancer incidence rate decreased by 20% compared to 00, and the female colorectal cancer incidence rate decreased by about 25% compared to 00, indicating that colonoscopy screening has played a significant preventive role in preventing colon cancer.

According to the data published by China Cancer Center in 2019, there are about 400,000 new cases of colorectal cancer and 200,000 deaths in China every year, and timely treatment in the early stage of cancer can bring its cure rate to more than 90%, so our health commission reminds residents over 40 years old to go for colonoscopy regularly every year to keep abreast of their intestinal health.

Summarize:

Intestinal health is the most basic guarantee of people's health, in addition to regular colonoscopy people should also pay attention to diet, exercise, regular work, and rest in life. Especially for patients suffering from intestinal diseases, we should reduce the intake of high fat, high protein, and high sugar, and remember to open our legs and don't be greedy.
