Many people have heard of the name hemorrhoids, but few people can clearly explain what hemorrhoids are, what symptoms they have, and why. Let us answer these questions for you.
Hemorrhoids referred to in medicine include internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. It is a chronic disease of one or more soft venous clusters formed by varicose venous plexus at the bottom of the anorectum and anal mucosa. According to relevant census data, the incidence of anorectal diseases is 59.1%, and hemorrhoids account for 87.25% of all anorectal diseases, and internal hemorrhoids are the most common, accounting for 52.19% of all anorectal diseases. Both men and women can get the disease. The incidence rate of women is 67%, and the incidence rate of men is 53.9%. It can be affected at any age. Among them, it is more common in people aged 20-40, and it gradually worsens with age. "Ten people nine hemorrhoids" said.
The basic symptoms of hemorrhoids are:
Hematochezia: The main symptoms of internal hemorrhoids in the early stage include jet-like bleeding, spot bleeding, and blood on toilet paper. The blood is bright red, and external hemorrhoids will not cause bleeding.
Prolapse: The main symptoms of internal hemorrhoids in the middle and late stages are mainly due to enlargement of internal hemorrhoids and hemorrhoid nodules, which separate the mucosa and submucosa from the anal layer. During defecation, the internal hemorrhoid nodules can drop below the dentate line and free outside the anal canal.
Falling pain: It can be the main symptom of painful external hemorrhoids. Internal hemorrhoids are not painful when there is no inflammation. Falling pain often occurs in internal hemorrhoids infection, incarceration and strangulation necrosis, and often leads to severe falling pain.
In addition, the repeated prolapse of late internal hemorrhoids can cause relaxation of the anal stent muscles and increased secretions, resulting in often moist and unclean anal margins, itching and eczema. In severe cases, it can also cause friction and itching, and internal hemorrhoids bleeding can also cause Anemia, dizziness, fatigue, poor energy, loss of appetite, and dry stool are common symptoms of anemia.
There are seven main causes of hemorrhoids:
1. Poor stool habit: Squatting and reading the newspaper while going to the toilet will prolong the time of squatting and defecation, which can easily cause blood stasis in the anus and cecum and cause diseases. Excessive force during defecation, some people, regardless of whether the stool feels strong or not, blindly and constantly strive hard, which can only increase unnecessary burden on the cecum, anus and pelvic floor muscles and local blood stasis, causing the occurrence and spread of diseases.
2. Abnormal stool: Diarrhea and constipation are important causes of hemorrhoids. Constipation is the biggest curse. Long-term retention of toxic substances in the cecum can not only cause cecal cancer, but also the accumulation of feces, which affects blood circulation.
3. Chronic diseases: such as long-term poor nutrition and weak physique, leading to anal sphincter relaxation and weakness. Suffering from chronic bronchitis and emphysema for a long time, abdominal pressure rises due to cough and asthma, and pelvic stasis. Chronic hepatitis, cirrhosis, diarrhea, colitis, etc. are all triggers for anorectal diseases.
4. Diet reasons: the quality of food, the variety of vegetables and the increase or decrease in quantity, the content of protein, fat, starch, cellulose, etc., and the amount of water intake can directly affect the composition of feces and cause anal and cecal diseases. .
5. Physiological reasons: the colon and cecum are the main organs for transporting food residues and storing feces. After the food is decomposed and absorbed in the body, the residues often contain a large amount of harmful substances, which can cause tumors if they stay in the colon and cecum for a long time.
6. Anatomical reasons: Anal vein system and vena cava system are at the lower end of the cecum. There are many venous plexuses and anastomoses. The vein wall is weak, resistance to pressure is reduced, and the submucosal tissue of the cecum is loose, which is conducive to the expansion of varicose veins and easy formation. hemorrhoid.
7. Causes of abnormal embryonic development: abnormal development process, many congenital anorectal diseases can occur in the anus and cecum, such as congenital anal disease, congenital cecum-vaginal fistula, congenital megacolon, etc.
