Colonoscopy can't be done if you want to.

Of course, normal people don't need colonoscopy. After all, colonoscopy is not a very simple clinical examination. It takes two days of light diet and two days of laxatives to prepare. So colonoscopy can't be done if you want to.

Clinically, enteroscopy is similar to gastroscope, which is to observe the internal situation of intestinal tract under direct vision, so enteroscopy is the simplest and most effective clinical examination method to find early intestinal tumors, polyps and intestinal cancer.

People over the age of 8.40 are safe first, and it is best to have a gastroscope health check regularly.

9. If the blood test shows that tumor markers are elevated, it is also recommended to routinely check gastrointestinal endoscopy.

So let's look at what I said above. If you don't have the above performance, you can have a physical examination after 40 years old.

Is it necessary for a 30-year-old person to have a colonoscopy? I'm a doctor in gastrointestinal surgery. Let me answer this question.

When we say colonoscopy, we mainly mean colonoscopy. Generally, colonoscopy can only observe all the colon and rectum, and a small part of the terminal ileum. The main diagnosis is colorectal cancer, intestinal polyps, ulcerative colon cancer, Crohn's disease, intestinal bleeding and so on.

If an ordinary person has no family history such as cancer, chronic enteritis, parasites, and no discomfort, there is no need for colonoscopy. For the general population, if you want to do cancer screening, it is recommended to start the first colonoscopy at the age of 45.

For a 30-year-old person, I suggest colonoscopy to make a definite diagnosis if:

(1) Repeated bloody stool

Patients with bloody stool, especially dark red stool, need to be careful of intestinal cancer or intestinal polyps when blood and stool are mixed together. There is also mucus pus and bloody stool, accompanied by abdominal pain, fever and other symptoms. Be careful of inflammatory bowel diseases such as ulcerative colitis, and colonoscopy is also needed.

Patients with positive fecal occult blood should first check the gastroscope to determine whether there is upper gastrointestinal bleeding. If there is no problem, a colonoscopy may be needed.

(2) Diarrhea or constipation

Changes in defecation habits, long-term diarrhea, irregular stool, or constipation, diarrhea and constipation appear alternately, which need to be paid attention to.

(3) Diagnose precancerous lesions such as intestinal polyp, chronic enteritis and inflammatory bowel disease.

Patients with colorectal polyps need to check whether they are cut clean and whether there are new polyps after polypectomy. There are also patients with precancerous lesions such as chronic colitis, Crohn's disease and ulcerative colitis. It is necessary to review colonoscopy regularly to monitor the therapeutic effect and prevent canceration.

(4) Family members of familial adenomatous polyposis or Lynch syndrome.

Familial adenomatous polyposis and Lynch syndrome are two hereditary bowel cancer syndromes. Because of genetic abnormality, the onset time of cancer is advanced. If these two diseases are diagnosed, regular colonoscopy should be started as soon as possible.

(5) patients with unexplained emaciation

If you suddenly lose a lot of weight, your food intake has not decreased, and you can't find a clear reason, you should also consider doing colonoscopy to see if there is any possibility of intestinal cancer.

(6) Patients with chronic abdominal pain

Abdominal pain is a common symptom. If the patient has chronic abdominal pain and cannot find the cause, cholecystitis, cholecystolithiasis, appendicitis and gastritis can be ruled out. Considering that abdominal pain is related to the large intestine, colonoscopy is recommended.

(7) Other examinations indicate that there are diseases in the intestine.

For example, the tumor marker CEA was found to be elevated during physical examination, and no clear reason could be found, so colonoscopy was needed for a clear diagnosis. Or abdominal color Doppler ultrasound, CT and other examinations, rectal digital examination, found intestinal diseases, need further diagnosis, need to do colonoscopy.

In addition to these conditions, there are other conditions that may require colonoscopy, such as acute lower gastrointestinal bleeding.

I hope my answer is helpful to everyone. If you have any questions, please pay attention to the consultation.

Is it necessary to do colonoscopy at the age of 30? The answer is: if there is nothing unusual, colonoscopy is unnecessary.

From the perspective of tumor screening, the so-called tumor screening is aimed at asymptomatic "healthy people". There is no need to check colonoscopy indiscriminately regardless of age. Recommended according to relevant guidelines. General risk groups can consider starting colonoscopy screening after the age of 45. If no abnormality is found, it can be done once every 10 year. If abnormalities are found, they will be treated or followed up. However, colonoscopy is not the only screening method. According to the requirements of the guidelines, the general risk population aged 45 to 75 can consider doing an annual fecal immunochemical test or a high-sensitivity guaiac fecal occult blood test; Or do a multi-target fecal DNA test every 3 years; Or do a CT colonoscopy or sigmoidoscopy every 5 years; Of course, colonoscopy can also be done once every 10 year. This means that no abnormality was found in the first inspection. If anomalies are found, of course, the time interval of handling and review should be determined according to the anomalies found. From the age of 75 to 85, it is necessary to decide whether to continue screening according to the preferences of the parties, life expectancy, health status and previous screening history. If you decide to continue the screening, you can also follow the above screening plan. Those over 85 years old are generally not recommended to continue screening. In the high-risk population of colonoscopy, the screening age can be advanced appropriately, and the screening interval is shorter.

If there are any abnormalities, such as bloody stool, abnormal stool shape, long-term constipation or diarrhea or both, it is necessary to make a diagnosis. Of course, it is not limited to age. You should do it at the age of 30, and even children can consider doing colonoscopy.

I'm Dr. Xiaoying. Colonoscopy is the best examination to find early colorectal cancer. Early colorectal cancer can be asymptomatic. Because of this, many friends are worried about getting colorectal cancer. They are only 30 years old. Do you want to have a colonoscopy?

Colonoscopy can only check the lesions of colon and rectum, but not the diseases of small intestine. Because the mirror enters through the anus, it can only enter the large intestine, which is what we call the large intestine The large intestine is full of feces, so you must take laxatives before the examination. According to the appointment time, the doctor will give you a laxative, so be sure to pull it clean. If they can't be pulled clean, it will also affect the doctor's observation of the structure in the large intestine. In case it affects judgment and misses a small cancer, it will be troublesome. So be sure to take laxatives as required and prepare for the gastrointestinal tract.

Colonoscopy is recommended if

1. Repeated bloody stool

Repeated bloody stools are bright red, indicating gastrointestinal bleeding. Red blood is colorectal bleeding, and black blood is upper gastrointestinal bleeding. No matter how much blood you have in your stool, you should have a colonoscopy.

2. Repeated constipation, diarrhea or both appear alternately.

Recurrent diarrhea and constipation appear alternately, which may be gastrointestinal dysfunction or a symptom of colon cancer. Many elderly people will be constipated, and they will mistake it for simple constipation, but they don't know that they have colon cancer. In many cases, symptoms appear for several months before seeing a doctor.

3. Have a family history of colon cancer

Anyone with a family history of colon cancer, whether parents, cousins or cousins, should be vigilant. If you also have gastrointestinal discomfort, you can rest assured without colonoscopy.

4. There is no obvious incentive to lose weight obviously.

There is no obvious incentive to lose weight, and the weight loss is more than 5kg. Pay attention to the possibility of cancer. If you have been working hard recently, you can't eat well and feel bad, which leads to weight loss, this doesn't count.

The following case is a 64-year-old male with epigastric discomfort for 2 months and poor stool for 5 days. He recently lost weight and CEA increased significantly. When experienced doctors hear this medical history, the first thing that comes to mind is colon cancer. Sure enough, CT found that colon cancer was accompanied by multiple liver metastases.

In fact, every doctor has no definite answer about when to start colonoscopy. Some people say you need to do it after 45, and some doctors say you are 35. But some people find colon cancer at the age of 30. So my suggestion is that if you really don't feel at ease, it doesn't hurt to have a colonoscopy screening at the age of 30. If you can, you can go back for a review after three to five years. I might as well go instead of worrying about going.

Let's start with the conclusion: at the age of 30, colonoscopy is not necessary if there are no specific physical symptoms or discomfort, but colonoscopy is necessary if there are long-term abdominal pain, diarrhea, constipation or other lower abdominal discomfort. Therefore, we should tell the truth, not generalize.

Then, as the subject asked, is it necessary to do colonoscopy at the age of 30? Let's analyze the recommended age, advantages and disadvantages of the exam.

Recommended physical examination age for colonoscopy

Friends who often read my popular science articles should be familiar with the recommended age of my first colonoscopy: 35~40 years old, that is to say, even if there is nothing abnormal in the gastrointestinal tract after 35 years old, it is best to have a gastroscope as a physical examination. Let me talk about the basis and reasons for recommending this age group:

The data show that the detection rate of polyps in people over 40 years old who receive colonoscopy increases with age. An article published in Chinese Journal of Gastroenteroscopy divided physical examination and colonoscopy into groups according to every 10 years old, and analyzed the relationship between polyp growth and age by counting the detection rate of polyps. The results showed that the detection rate of polyps in these people increased from 19.77% in the 40-50 age group to 48. 15% in the 70 age group. It can be seen that age is one of the factors for the growth of intestinal polyps.

Combined with the above data, according to another article about canceration of intestinal adenomatous polyp, it usually takes 5~ 15 years for adenomatous polyp to grow into canceration. I suggest that the first asymptomatic physical examination colonoscopy should be carried out between 35 and 40 years old.

Advantages and disadvantages of colonoscopy

Looking back at today's question, since colonoscopy is recommended for asymptomatic physical examination of 35-40 years old, then 30 years old is definitely a little early, and there is really no need for examination. However, I usually encourage people who care about their health, so I will explain the advantages and disadvantages of enteroscopy in my eyes here, and then the subjects can analyze whether it is necessary to do it according to their actual situation.

First of all, any inspection method has certain risks. Because colonoscopy is an invasive examination method, the risk is inevitable. Theoretically, the complications of enteroscopy include intestinal perforation, intestinal mucosal bleeding, mesenteric tear, infection and cardiovascular and cerebrovascular events. Due to the development of colonoscopy technology and the perfection of decontamination system, the probability of the above complications is extremely low. But it is undeniable that although the probability is low, it still happened. Cases of intestinal perforation or cardiovascular and cerebrovascular events are reported every year. Therefore, whether or not to do an inspection depends first on whether you can accept the risks brought by the inspection;

Secondly, colonoscopy will cause some discomfort from preparation to completion. Intestinal preparation is necessary before colonoscopy, and it is the key to ensure the smooth progress of colonoscopy. Because of the need to drink a lot of water to cooperate with the preparation of bowel cleansing, and at the same time, it is necessary to keep an empty stomach until the end of the examination, so many people are devastated in the preparation of bowel cleansing. If you don't choose painless colonoscopy, there is a high probability that there will be common reactions such as abdominal distension and abdominal pain during the examination. Therefore, before choosing colonoscopy, you should also make psychological preparations in advance to see if you can bear these discomforts;

Finally, excluding the above two so-called shortcomings, the sooner colonoscopy is done, the better. From my actual clinical experience, among the patients with advanced intestinal cancer I have tested, the youngest is 28 years old, and I was shocked at that time. Therefore, if you can accept the above two risks or discomforts, you should do colonoscopy as soon as possible. Although it is not necessary to do it once a month, 1~2 years is completely harmless to the body.

Physical examination strategy for colonoscopy diseases

To sum up, if I have to say whether I should do colonoscopy at the age of 30, I will be more specific:

If you are a healthy person, it is a little early to do preventive colonoscopy at the age of 30. Because from the big data, intestinal polyps or malignant tumors began to show signs after middle age. But if you can accept some risks or discomforts of colonoscopy, there is no harm in having a health check as soon as possible. If problems are found, they can be dealt with as soon as possible. If there is no problem, you will be open-minded and happy.

However, if it is a person with long-term abdominal pain, abdominal distension or changes in defecation habits, or even bloody stool for a long time, then no matter how old he is, he should do colonoscopy in a short time to rule out the possibility of malignant tumor.

Therefore, we can also extend this idea to other physical examinations. It is necessary to understand the purpose of the inspection first, and then understand the disadvantages of the inspection, such as inspection experience, complications, risks and so on. According to the doctor's advice, I will decide whether to do this kind of examination according to my actual physical condition. This can not only prevent the body from being damaged by frequent over-examination, but also carry out physical examination in time to avoid the progress and deterioration of the disease.

Finally, please remember one sentence, all things related to physical and mental health should be discussed on the basis of facts and people, distinguish advantages and disadvantages, and follow the doctor's advice.

Colonoscopy is the most effective and direct examination method to distinguish intestinal diseases, which is of great help to the diagnosis of intestinal diseases and the prevention of intestinal cancer. The appearance and popularization of colonoscopy make it easier to find intestinal cancer in the early stage, which provides sufficient diagnostic basis for the treatment of intestinal cancer and other intestinal diseases.

Although colonoscopy is an important means to prevent and diagnose intestinal diseases, it does not mean that everyone must undergo colonoscopy. But for people over 30 years old, colonoscopy is still necessary. Xiaoke has the following opinions and suggestions:

First of all, there is no need to do colonoscopy for 30-year-old healthy people without any diseases, because according to the age of being prone to intestinal cancer and intestinal diseases, the occurrence of intestinal cancer and intestinal diseases is still concentrated in people over 40 years old, so it is not necessary for 30-year-old healthy people to do colonoscopy.

However, if the 30-year-old has the following symptoms, colonoscopy is still needed:

1. Long-term diarrhea and constipation persist and recur: diarrhea and constipation sometimes alternate. For the 30-year-old population with diarrhea and constipation for a long time, colonoscopy should be actively carried out to determine whether there are intestinal diseases.

2. Bloody stool: Bloody stool is also a common symptom of intestinal diseases. Hemorrhoids are common diseases that cause hematochezia in clinic, but there are also cases in which intestinal cancer is misdiagnosed as hemorrhoids. Therefore, when there are symptoms of bloody stool for a long time, you should go to the hospital for detailed examination and colonoscopy to avoid missing diagnosis of intestinal cancer or other intestinal diseases.

3. Mucous stool and purulent bloody stool: The appearance of these two symptoms mostly indicates that there is infection and chronic inflammation in the patient's intestine. In addition, such as intestinal polyps, intestinal cancer, will also have the above performance, so patients with mucus stool and purulent blood stool should do colonoscopy in time.

4. Re-examination after colorectal cancer surgery or intestinal polypectomy: Re-examination after colorectal cancer surgery and intestinal polypectomy is helpful to understand the postoperative recovery of patients, and can also achieve effective early treatment of recurrence.

5. People with intestinal cancer in the family: Most cancers are inherited by such a factor, so people with intestinal cancer in the family, especially those with intestinal cancer in immediate family members, must have regular physical examinations.

The 30-year-old people who exist in the above five points should undergo colonoscopy. In addition, colonoscopy also has contraindications, such as severe anorectal infection, various acute enteritis, bacillary dysentery and so on.

Hello, the main purpose of colonoscopy is to find colorectal diseases as early as possible and screen intestinal cancer as early as possible. For 30-year-old people, colonoscopy should be put on the agenda, because domestic epidemiological surveys show that the incidence of colorectal cancer is high among young people (30 years old), and most of them are low rectal cancer, which can be found by general rectal digital examination. Therefore, if you have digestive tract symptoms, such as bloody stool, or change your bowel habits, you should go to the hospital as soon as possible, and both rectal digital examination and colonoscopy need to be done. In addition, if you have a family history of intestinal cancer, a history of cancer, a history of intestinal adenoma or polyp, or mucus and bloody stools, chronic diarrhea or constipation, you are all at high risk, so you should have a fibercolonoscopy. Because even the examination of tumor markers has a low positive rate for the diagnosis of early colorectal cancer, colonoscopy is necessary even for young people.

Gastroenteroscopy is a good method to diagnose digestive tract diseases and a gold standard in clinic. Senior medical professionals call it the protector of digestive tract.

However, gastrointestinal endoscopy is not a routine physical examination item, and there are indications for examination. For example: dysphagia, abdominal pain, acid regurgitation, indigestion, nausea, hematemesis, diarrhea, changes in stool characteristics, and so on.

So it should be decided by doctors, not by age.

Another warm reminder: check whether hepatitis B surface antigen is positive before the examination to decide the examination time; Need to fast for more than eight hours. In the morning, inspectors don't eat breakfast that day, and in the afternoon, inspectors don't eat lunch that day; If you have had other examinations before, such as barium meal examination of gastrointestinal tract, abdominal ct or gastroscopy, you must submit the examination report and pathological report to the doctor for reference; Traditional gastroscopy brings great pain to patients, and it is difficult to carry out the examination. Painless gastrointestinal endoscopy brings confidence and hope to patients with digestive tract.

It is necessary to check at any time, and no one can guarantee that he is all right. Now all kinds of diseases can happen at any age, especially cancer is getting younger! Our doctor suggested: if there is any problem, do relevant examination in time and recheck it if necessary. There is no need to be overly nervous, multiple checks!

Whether there are family history and clinical symptoms, such as bloody stool without hemorrhoids, unexplained intestinal obstruction, etc.
