"Generally, some chyme is discharged into the duodenum 5 minutes after the food enters the stomach. The emptying speed of different foods is different, which is related to the physical properties and chemical composition of the food."

"Then food enters the intestines, nutrients are absorbed, and what cannot be absorbed becomes stool and is stored in the lower part of the colon."

"When the amount of feces reaches a certain level, it will stimulate the intestinal tract through pressure and physiological receptors, generally the receptors on the rectal wall, forming a sense of defecation."

Chu Zhixi heard that Wu Mian was talking nonsense about defecation with patients, and it was just the simplest science popularization. He felt boring, so he sat back again.

"Dr. Wu, is that your girlfriend?"

"Well, right or wrong, it''s a fiancee, not a girlfriend." Wu Mian nodded and narrowed his eyes.

"That''s nice, childhood sweetheart?"

"It''s not a childhood sweetheart. It''s my junior sister when I was at school."

"Awesome!" the patient lowered his voice and said, but stretched out his right hand and raised his thumb. "I know how to hook up with my younger martial sister when I go to school. It''s amazing! I don''t understand when I go to school. I soak in Internet cafes every day. I always think it may be easier to find a girlfriend after graduation. Who knows that girls have higher eyes than one."

"Hey," said Wu Mian with a smile, "that''s right. Keep your voice down. My fiancee heard what you just said. She doesn''t know how many questions she wants to chase me to ask."

"I know, I know." the patient laughed happily. "Dr. Wu, go on, do I always have feces in my rectum? I''ll go! Rectum, rectum, that''s what happened!"

Wu Mian saw that the patient began to associate disorderly, crying and laughing.

"Your disease is a gastrointestinal disorder, and the etiology has not been fully studied.

The pathogenesis of irritable bowel syndrome includes abnormal gastrointestinal motility, visceral sensory abnormalities, neurological and immune factors, low fiber diet, intestinal infection, psychopsychological factors, brain gut interaction, gender factors and so on. "

"..." the patient was stunned.

"For example, let''s not talk about your situation. Do people around you have diarrhea all year round?"

"Yes, my aunt has diarrhea all the year round. Later, she went to Tongji to do an enteroscopy and found polyps. After taking them down for pathology, they were precancerous lesions." the patient was also tuberculosis. Wu Mian opened his head and continued, "I thought it was polyps, but I avoided colon cancer. The diarrhea still didn''t get better."

"What you said is the manifestation of hyperactivity of intestinal motility. The transmission time of small intestine is significantly shortened, and the mean and maximum values of colonic motility index and high amplitude propulsive contraction are significantly increased. Constipation IBS is just the opposite, manifested as insufficient intestinal motility.

In other words, patients with hyperactivity of intestinal motility are generally very thin, and a few will have the performance of malnutrition. I don''t know how good a girl wants to be like this. She can have both weight loss and delicious food! "

"Er... Really, my aunt is very thin," the patient recalled.

"According to the theory of traditional Chinese medicine, this situation is called five shift stool, also known as morning diarrhea, kidney diarrhea and chicken chirping diarrhea.

It first appeared in the "heart method of Danxi" - there is a cave diarrhea at the fifth watch every day... It is forbidden to eat and drink with the festival, but there is nothing in the first half of the day, and its diarrhea is repeated near the fifth watch.

It is a chronic and recurrent diarrhea at dawn. It is mainly manifested in epigastric pain or no pain every five minutes before dawn, diarrhea with bowel sounds, peace after diarrhea, irregular stool, no mucus and pus and blood. "

"I''ll ask my aunt if she has this symptom. Is there such a disease? Can traditional Chinese medicine treat it?" the patient has countless questions.

"Lack of innate endowment, or loss of nourishment after tomorrow,... The cold water sandwiched between the intestines goes down with the valley is diarrhea." Wu Mian said a long paragraph with the theory of traditional Chinese medicine, which stunned the patient.

"In addition to the deficiency and failure of kidney yang, there are such manifestations as spleen deficiency and dampness, and liver Qi riding on the spleen."

"Dr. Wu, are you Chinese medicine?"

"No, I''m western medicine, but sometimes I''d like to read the books of traditional Chinese medicine." Wu Mian stroked the rabbit''s ear. "Is it reasonable to combine traditional Chinese and Western medicine?"

"Pulse, can you?"

Wu Mian stretched out his hand and wore two pairs of gloves. Sweat could be seen sticking to the inner gloves.

"Sorry." the patient looked at Wu Mian''s outstretched hand. "Dr. Wu, you are really hard."

"It''s OK. The doctors working in the designated hospitals are really hard. The specialists who come are sent there to stare at the critically ill patients every day."

"Er... My illness doesn''t matter."

Wu Mian also told the patients about the possible inducing factors that may lead to "straight intestines", such as visceral sensory abnormalities, central sensory abnormalities, abnormal regulation of brain intestinal axis, intestinal infection and inflammatory reaction, mental and psychological factors.

Idle is also idle. Talk with patients. Time flies.

"After the spring flowers bloom, you go to the hospital for two kinds of examinations - one is stool routine and the other is colonoscopy. I think there should be no problem. If there is specific treatment, listen to the doctor at that time."

"Dr. Wu, what''s the disease again?"

The patient picked up his mobile phone and began to record the name of irritable bowel syndrome. What he never expected was that he was just straight hearted. Dr. Wu told himself about pathophysiology for less than half an hour.

But that''s true.

Nurses and volunteers began to distribute boxed meals. Wu Mian narrowed his eyes and said, "have dinner. I won''t talk to you."

"Well, Dr. Wu works hard."

"Let''s go."

"Dr. Wu, wait a minute. I have one last thing." the patient suddenly remembered something and stopped Wu Mian. "I heard that many people can leave the hospital and go home these days?"

"Yes, more and more patients will be discharged every day in the future."

"I check every day, but it doesn''t turn negative. What do you say I do?" the patient said this, a little sad.

"It will get better. There are differences in the speed of recovery according to different physique."

"I''m worried that the shelter hospital is closed. Where do you think I''m going?"

"Don''t think so much." Wu Mian comforted. "Delicious, good drink and good sleep are the best medicine. Step by step, this is a brand-new virus. No one knows how to treat it."

"Dr. Wu, I read many articles that there are special drugs."

"False." Wu Mian said with certainty, "the only certainty now is that this is a self limiting disease, that is, it needs your own immunity to control. For a cold, taking medicine for 7 days is good, and not taking medicine for 1 week is good. That''s the truth."

The patient was obviously disappointed.

"Don''t be too stressed. It''s like a big cold. You can see in the shelter that there are more and more discharged patients. Be calm and happy, and you can turn negative soon." Wu Mian stroked the rabbit''s ears on his head and said with a smile.
