The anal canal is a complex and sensitive organ
It is important to understand the structure of the anal canal in order to prevent hemorrhoids. The anal canal connects to the rectum at the upper end and ends at the anus at the lower end. "The word "anus" stands for the hole in the buttocks, and "door" means access. The anal canal is the lower opening of the anal canal, usually in a sagittal position. The anal canal is the organ responsible for expelling food residues and metabolic waste (including exhaust gas).
The large intestine is the continuation of the digestive organs such as the esophagus, stomach, duodenum, and small intestine, including the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum, and finally connects to the anal canal. It is the area below the sigmoid colon that is associated with defecation. The wall of the rectum is dilated by the action of stool, which causes the person to have the urge to have a bowel movement through autonomic reflexes, and then the stool is expelled under the control of the somatic nerves.
The length of the anal canal is about 3 cm. When the fetus reaches 8 to 9 weeks of age, the endoderm of the primitive rectum fuses with the ectoderm of the primitive rectum to form the anal canal, which is called the dentate line because of the serrated shape of their union. The dentate line is approximately 1.5 cm from the anus.
The inner part of the dentate line is bounded by the same autonomic nerves as the large intestine, so that little pain is felt. On the other hand, the lateral part of the dentate line, close to the skin, is innervated by the same somatic nerves as the skin, and is therefore more sensitive and painful when stimulated.
Because they are innervated by two different nervous systems, the symptoms of hemorrhoids vary from site to site.
In addition, there is a fossa on the dentate line that opens upward, called the anal sinus, which is the opening of the anal glands.
The sinus is the opening of the anal glands. The sinus is the opening of the anal glands. The sinus is often filled with fecal debris and is susceptible to bacterial infection, which is the cause of anal impotence.
The two muscles around the anal canal
Why do humans get hemorrhoids
Walking upright has created a highly civilized society and a brilliant culture with free hands. However, this way of walking also makes the area around the anal canal more prone to bruising and hemorrhoids, a disease that can easily develop.
What kind of disease are hemorrhoids?
Hemorrhoids are a disease that is closely related to the structure of the anal canal.
The anal canal does not close completely with only the surrounding muscles (the internal and external anal sphincter), leaving a gap of about 1 mm in diameter.
There is a gap of about 1 mm in diameter. In order to fill this gap, there is a tissue called the "anal cushion" under the skin of the anal canal, which consists of small, dense veins (venous plexus), smooth muscle and elastic fibers.
From about 30 years of age, the muscles and elastic fibers that make up the anal cushion gradually age and break down. If you strain very hard during bowel movements, you will exert greater pressure on the blood vessels in the plexus, causing blood to stagnate, resulting in a localized mass known as a hemorrhoid.
It may be a personal habit to use forceful bowel movements, but usually it is due to constipation, so people who are constipated are prone to hemorrhoids.
People are prone to hemorrhoids.
So, why does the human anal canal have such a structure?
Aging contributes to the formation of hemorrhoids
With the improvement of living standards and the development of medicine, the number of elderly people over 80 years of age has increased greatly, and human beings are living longer and longer. As a result, the anal canal, which can only support 40 years, is forced to extend its "useful life," and aging causes serious damage to the tissue of the anal cushion, making it easy to form hemorrhoids.
As mentioned earlier, the evolution of humans from crawling to walking upright has increased the burden on the anal canal.
In reptiles, the spine is horizontal and the body is supported by the limbs, so the anal canal bears less of a burden.
For humans walking upright, the weight of the upper body is concentrated on the waist and buttocks, causing the
The muscles and blood vessels around the anal canal are constricted, which seriously affects blood circulation. The stagnation of blood makes it difficult to expel waste products from the body, which in turn causes hemorrhoids.
However, the significance of walking upright for humans is very significant. The most important thing was that the freed hands learned to use tools and created a splendid human civilization.
Is the incidence of hemorrhoids related to gender
Because men and women have different body structures, they have different types and symptoms of anal canal diseases such as hemorrhoids.
Women are also prone to hemorrhoids and other anal diseases
Men are often thought of as being prone to hemorrhoids, but women actually suffer more often. This is because about 70 percent of the patients treated in hospitals are women.
Women are able to speak openly about their condition at our hospital.
The reason why women are prone to hemorrhoids is not only the unique physiological phenomenon of pregnancy and childbirth, but also the culprit of hemorrhoids - constipation. This is because constipated patients often overexert themselves during bowel movements, which can easily lead to anal fissures or hemorrhoids.
Women are more prone to constipation than men because many women often hold off going to the bathroom at work or when they are out and about, and many women are overly concerned about their body image and often diet to lose weight, which can make constipation more serious. In addition, due to hormonal effects, women's bowel movements become slow before menstruation, which can easily cause constipation.
Women often suffer from hemorrhoids after pregnancy and childbirth. During pregnancy, the enlarged uterus compresses the
During pregnancy, the enlarged uterus compresses the rectum, causing the veins around the anal canal and rectum to stagnate, which can easily lead to hemorrhoids. In addition, overexertion during childbirth can also be a cause of hemorrhoids. After childbirth, the abdominal muscles and intestinal tissues are looser, and breastfeeding causes a lot of water loss in the body, making the stools dry and hard, and therefore prone to constipation.
The consequences of ignoring hemorrhoids
No matter what kind of disease, if left unattended, it will lead to deterioration of the disease, and in serious cases, it may even threaten the life of the patient.
Rectal cancer and colon cancer are easily confused with hemorrhoids
Many people think that hemorrhoids are not a serious disease, so they don't take it seriously. In fact, many people who think they have hemorrhoids are actually suffering from rectal or colon cancer, especially since the proportion of Japanese people suffering from rectal and colon cancer has been increasing every year in recent years.
This is because rectal and colon cancers also have symptoms such as bleeding from the anus and blood in the stool, and laymen often think that they are just ordinary hemorrhoids.
This is because rectal and colon cancers also have symptoms such as bleeding from the anus and blood in the stool.
In particular, people who have suffered from hemorrhoids for a long time are more likely to mistake blood in the stool of rectal or colon cancer for hemorrhoids.
Bleeding. If you have never had hemorrhoids, you may be alarmed at the sight of blood in your stool and go to the doctor.
Some anal canal diseases can cause cancer
If you have anal canal disease but do not get treatment early, it can easily lead to anal canal cancer.
There are two types of cancers near the anal canal, one is rectal cancer which occurs in the rectum,
One is rectal cancer, which occurs in the rectum, and the other is cancer of the anal canal, which occurs when a person has suffered from anal canal disease for a long time but does not receive treatment.
The main symptom of anal canal cancer is anal canal pain with discharge Q If the anal canal pain lasts for a long time and discharge is present, please consult a specialist and have the rectum and colon examined.
If there is no abnormality in the rectum or colon, it is important to have an examination every 2 years.
Anal canal disease and perianal inflammation
Anal canal disease is closely related to perianal inflammation. When health is poor, the immune system is weakened and susceptible to inflammatory diseases that can lead to or worsen anal canal disease.
Perianal inflammation is the culprit of anal canal disease
There are three main types of anal canal diseases: hemorrhoids, anal fissures, and anal impotence. One of the risk factors for the development and worsening of anal canal diseases is perianal inflammation, which is the inflammation around the anal canal.
When attacked by bacteria or viruses, the body's immune system is generally able to fight off external enemies and maintain good health. The cells that play a role in immunity include macrophages, T-lymphocytes, and B-lymphocytes.
The mouth, vagina and anus have local immune systems that are less susceptible to germs and inflammation.
We can refer to the factors that harm the body's health as attack factors, such as viruses and bacteria, and the immune cells that defend the body against these attack factors as defense factors.
If the immune system decreases, perianal inflammation can occur, which can worsen the symptoms of anal canal diseases such as hemorrhoids.
Six factors that cause perianal inflammation
The six major factors that cause perianal inflammation in daily life are abnormal bowel movements, physical fatigue, mental stress, exposure to cold, alcohol consumption, and menstruation.
The attack and defense factors explain why these six factors can cause perianal inflammation. The passage of stool through the anal canal is an aggressive factor for the anal canal. This aggression factor increases during constipation and diarrhea. Alcohol consumption can also increase the attack factor.
In addition, physical fatigue and stress can depress the local immune function of the anal canal, resulting in a decrease in defense factors.
In healthy people, the defense and attack factors are in balance, so they are less likely to develop hemorrhoids. The six factors mentioned above disrupt this balance, which can lead to or worsen anal canal disease.
If you get poop on your hands and don't wash it off in time, the skin of your hands will feel uncomfortable because of the large amount of bacteria in the poop.
For constipated people, stool containing a lot of bacteria stays in the rectum or anal canal for a long time, which can easily cause inflammation and lead to hemorrhoids.
Therefore, we can classify these six factors into two categories: "The factors that increase the attack factor and cause hemorrhoids
The factors that cause hemorrhoids are abnormal bowel movements, alcohol consumption, and menstruation, while the factors that cause hemorrhoids due to a decrease in defense factors are physical fatigue, mental stress, and cold. Cold.
Anal canal disease and perianal inflammation
if the body is cold, the blood vessels around the anal canal will constrict, slowing blood circulation and causing bruising, which can easily lead to perianal inflammation.
Nowadays, with the popularity of air conditioning, there is an increase in the number of patients who suffer from hemorrhoids caused by cold in the buttocks during the summer. Hemorrhoids are considered to be a disease that is closely related to coldness in the body, so it is important to avoid excessive use of air conditioning. If you work in a place where the room temperature is often low, you should pay special attention to keeping warm.
It is recommended that you soak your buttocks in a sitz bath immediately after a bowel movement to improve circulation and eliminate blood stagnation, thus preventing the development of hemorrhoids. However, since anal impotence is a bacterial infection that causes localized septicemia, sitting in warm water can aggravate the symptoms of septicemia and pain, so patients with anal impotence should avoid using this method o
Excessive alcohol consumption can also trigger hemorrhoids. Alcohol, the main component of wine, is a type of alcohol that dilates blood We can think of it as an attack factor for perianal inflammation. To prevent an increase in the number of attack factors, the amount of alcohol consumed should be kept to a certain level. You should not drink more than 1 beer, 1 bottle of sake (about 180 ml) or 2 glasses of wine per day.
The exact cause of perianal inflammation due to menstruation is not known, but it is generally believed to be related to dramatic changes in hormone levels such as progesterone around the time of menstruation.
Because menstruation has a certain pattern, constipation and perianal inflammation caused by menstruation are easier to prevent.
If you are prone to constipation during menstruation, you can start eating more dietary fiber foods such as beans and seaweed a few days before your period, and drink yogurt to regulate your bowel movements to avoid constipation. The anal canal is burdened.
The actual fact is that eating foods rich in dietary fiber can help prevent constipation, and getting enough rest can help relieve physical fatigue and reduce mental stress, thus strengthening the immune system.
The body's self-healing power can fight disease
As mentioned earlier, health is actually a state of the body in which the attack and defense factors are in balance. If bacteria or viruses invade the body, immune cells such as macrophages and lymphocytes will defeat the invaders and restore the body to health.
Fever and sweating during illness are symptoms of immune cells fighting against the invaders. In order to cure the disease and restore health, the patient's self-healing power plays a very important role, and drugs only play a supplementary role
Therefore, it is important to improve immunity and self-healing in the treatment of hemorrhoids, and to maintain a balance of attack and defense factors.
The six factors mentioned above can trigger anal canal disease and make it worse. Therefore, to prevent and control hemorrhoids, it is important to make lifestyle changes to avoid these causative factors
