On the stage of life, feces is a unique substance, after it is formed, it is pushed to the distal part with the help of the peristalsis of the colon, and the contraction of the colon, like a natural driving force, allows the feces to continue to move forward.
This process often starts from the curvature of the liver, 2~3 times a day, at a steady rate of 1~2 cm per minute, after a series of storage, it finally reaches the left colon, and then enters the sigmoid colon.
However, after eating or waking up in the morning, total colonic motility due to gastrocolic reflexes or postural changes accelerates at a rate of 10 centimeters per hour.
At this time, when the amount of feces in the sigmoid colon accumulates to a certain extent, a certain amount of pressure is exerted on the intestinal wall, and at this moment, the defecation reflex is naturally triggered.

In the process, the peristalsis of the colon is like a magic of nature, silently pushing the feces forward. And feces also plays its unique role on the stage of life, and together with the body interprets a wordless symphony of life.

How can I tell if my stool is normal?
The first thing to do is to observe its color and shape. Normal stools should be yellow or brown and banana-shaped. If the stool is light or dark, or too soft or too hard, there may be a problem.
At the same time, pay attention to the smell of stool. Normal stool should have a faint foul smell, if the smell is too strong or has a peculiar smell such as fishy or sour, there may be problems such as digestive problems or intestinal infections.
In addition to this, the number of bowel movements and the sensation of bowel movements can also be considered. Normally, adults have 1-2 bowel movements a day, but if there are too many or too few bowel movements, or if they don't feel smooth, it can also be a sign of a problem.
02
When defecation, the stool is often "hard in the front and soft in the back", what's the matter?
First of all, we need to understand the peristalsis of the intestines. In the intestines, food debris is gradually compressed and digested, forming stool. Since the peristalsis of the intestines is from top to bottom, the time for which the feces stay in the intestines gradually increases.
This means that stool close to the anus stays in the intestine longer, the water is absorbed more, and therefore has a harder texture. The stool in front of it stays in the intestine for a shorter time, has more water, and has a softer texture.
In addition, diet is also a key factor in influencing stool hardness. If you don't get enough water, or if you don't get enough fiber, it can lead to dry, hard stools. And if the diet is rich in water and fiber, the stool will be softer.
In addition, the health of the gut can also affect the hardness of the stool. When the intestinal flora is balanced and the intestinal peristalsis is normal, the texture of the stool will be relatively stable.
And if there are diseases such as inflammation and polyps in the intestines, it will affect the normal peristalsis and secretory function of the intestines, resulting in changes in stool hardness.

How to improve the problem of hard stool before and soft after stool?
First of all, increase the intake of dietary fiber. Dietary fiber stimulates intestinal peristalsis and softens stools, thereby aiding bowel movements. Fruits, vegetables, whole-grain bread, etc. are all foods rich in dietary fiber, so you can eat more of them appropriately.
Second, maintain adequate water intake. Water is an important substance for maintaining intestinal lubrication, and if you don't take enough water, it can lead to dry intestines and hard stools. Therefore, to ensure adequate water intake every day, it is recommended to drink about 1.5-2 liters of water per day.
In addition, proper exercise can also help improve the problem of hard stools before and after softness. Exercise can promote intestinal peristalsis and accelerate the excretion of waste in the intestines, so it is recommended to do a moderate amount of aerobic exercise every day, such as walking, jogging, yoga, etc.
Finally, develop good bowel Xi. Have regular bowel movements and avoid forcing bowel movements when you are busy or when you don't feel the urge to defecate. At the same time, it is necessary to pay attention to the correct bowel posture and not to use too much force, so as not to cause damage to the anus.

It is recommended to know the main items of intestinal examination as early as possible
First of all, a stool routine is the basic item of the intestinal examination, which can help the doctor understand whether there are abnormalities such as inflammation, infection or parasites in the intestine. Through a routine stool test, the doctor can make a preliminary judgment about the health of the intestines.
Secondly, colonoscopy is one of the important means of intestinal examination. Colonoscopy can enter the intestine through the anus, directly observe the shape and color of the intestinal mucosa, and detect small lesions in the intestine. At the same time, colonoscopy can also perform a tissue biopsy to further confirm the nature of the lesion.
In addition, tumor marker examination is also one of the important items of intestinal examination. By detecting tumor marker levels in the blood, doctors can help detect the presence of intestinal tumors. Especially for high-risk groups, regular tumor marker testing can detect intestinal tumors early and improve the cure rate.
In addition to the above main items, there are some other intestinal examination items, such as abdominal CT, barium enema, etc., which can assist in stool routine, colonoscopy and tumor marker examination, and have a more comprehensive understanding of intestinal health.

People who are often constipated, what laxative foods can they eat?
1. Fruits: Fruits are rich in fiber and water, which helps stimulate intestinal peristalsis and promote bowel movements. It is recommended to eat more fruits such as apples, bananas, pears, and oranges.
2. Vegetables: Vegetables are also high-fiber foods that help improve constipation. It is recommended to eat more vegetables such as spinach, celery, carrots, pumpkin, etc.
3. Whole wheat bread and rice: Whole wheat bread and rice are high in fiber, which helps to increase bowel volume and stimulate bowel movements.
4. Legumes: Beans are also high-fiber foods that help improve constipation. It is recommended to eat more legumes such as red beans, mung beans, and black beans.
5. Honey: Honey contains natural sugars and enzymes that help promote intestinal peristalsis and relieve constipation symptoms.
