How does oxygen reach all parts of the body? How do the blood vessels get stuck little by little? Why is the respiratory system always invaded by germs...
Sometimes, medical and health care knowledge is boring, obscure, abstract and difficult to remember.
Life Times opened a "comic painting science" column to paint images to make this knowledge "live", so that you can understand and learn at a glance.
The intestinal "lao lai" is suppressed
In life, I will always endure because of various things, even defecation. My stomach suddenly grunted, but I was in a meeting; I was about to come out, but I couldn't find the toilet... All kinds of practical reasons and conditions are testing the endurance of many people.
In this issue, Life Times (search for "LT0385" in WeChat to pay attention) takes you to see the consequences of intestinal overload hoarding.

Advance: The road out of the city is blocked
After food enters the human body, it will be digested and absorbed by the stomach and small intestine, and most of the nutrients and water will be absorbed, and the remaining residue will enter the large intestine, gradually changing from a thin paste to a banana-like poop, and finally being pushed by the intestine to the closest part of the anus - the rectum.
Under the regular peristalsis of the intestines, the poop is pushed to the city gate (anus), where they merge with the poop that arrived earlier and apply to leave the city. The nerves in the anus act as dutiful dispatchers and immediately report the situation to the superior, the brain.
After receiving the message, the brain immediately observed the surrounding situation and found that the body was in a meeting and was not suitable for defecation, indicating that the dispatcher's application to open the city gate was rejected.
At the same time, the brain issued a command to the guard guarding the city gate, the sphincter, and the guards quickly assembled a group to firmly seal the city gate and block the way of the poop.
Retreat: The anus really can't stand it
Despite the obstruction of going out of the city, more and more poop came through the intestines, crowding the road. The guards at the city gate were under great pressure, and the city gate was in jeopardy.
In order to reduce the pressure at the city gate, the dispatcher nervous emergency evacuation part retreated to the rear and returned to the colon.
However, the stool that returns to the colon is constantly sucked away by the intestine, and the volume of the stool that loses water becomes smaller, and the pressure on the intestine is also reduced, and the stool intention gradually disappears.
These dry and hard poop become "old stubborn", which not only blocks the passage of normal poop, but also makes it difficult to be excreted.
Clearance: Defecation system traffic is paralyzed
When the owner of the body finally arrives at the toilet, the brain hurriedly issues a release order to the nerve, but the defecation process may not be as smooth as expected.
Long-term defecation, will lead to a decrease in the sensitivity of the intestinal wall pressure receptors, weakened defecation reflex, even if a lot of feces is accumulated in the rectum, the brain nervous system can not receive the signal of constipation, and then cause constipation, but also easy to cause hemorrhoids, fissures and other problems.
Not only that, the feces contain harmful substances such as hydrogen sulfide and fecal stinkin, which stay in the intestine for a long time, will destroy the intestinal flora environment, stimulate the intestinal mucosa, and bring symptoms such as indigestion, loss of appetite, hiccups and flatulence, and mental malaise.
Patients with constipation are often accompanied by intestinal polyposis lesions, and in severe cases, bowel cancer can be induced. For people with cardiovascular and cerebrovascular diseases, exertion will increase abdominal pressure, make the sympathetic nervous system excited, and easily induce cardiovascular and cerebrovascular acute events.
- Ends -
Doctors suggest that when you have a bowel intention, you should discharge it in time, if the stool intention disappears after holding the stool, you can drink more water appropriately, which can promote intestinal peristalsis, soften the dehydrated feces, and help to discharge smoothly.
In terms of frequency of bowel movements, as long as the number of bowel movements is greater than 3 times a week, it is normal. However, if the original regular bowel movements suddenly change, it is necessary to seek medical treatment in time to check for gastrointestinal related diseases. ▲
