In the face of increasingly intense social competition, many workers in the front line are increasingly casual about their diet. Eating, for them, has become a process of filling physical strength, rather than a way to savor food and enjoy life. The diet has become a casual habit, and with it comes all the pain and worry caused by anal diseases! The actual fact that you can’t get rid of the troubles brought about by “casual”, then solve it. The following will introduce you to the causes, symptoms, hazards and prevention of anal diseases. A. Internal and external factors leading to anorectal diseases (a) internal factors leading to anorectal diseases 1. physiological factors: colon and rectum are the main organs for transporting food residues and storing feces, and after food is decomposed and absorbed in the body, the residues often carry a lot of harmful substances, which can induce tumors when they remain in the colon and rectum for a long time. 2.Anatomical factors: There are a lot of special structures in the anorectum, such as anal fossa, anal gland, anal papilla, rectal flap and special vascular structure. The lack of venous valve in rectal vein makes the blood easy to stagnate. The portal vein system and vena cava system in the lower rectum, there are many venous plexus and anastomotic branches, weak vein wall, resistance to pressure is reduced, rectal submucosal tissue is loose, conducive to the expansion of varicose veins, easy to form hemorrhoids. 3, genetic factors: because of genetic gene defects, can produce multiple colon polyps, p-j syndrome (melanin spot – colon polyposis) and other hereditary anorectal diseases. 4, abnormal embryonic development factors: anorectal part is the human body in the embryonic development process of endoderm and ectoderm fusion each other, such as abnormal development process, can produce many congenital anorectal diseases in the anorectal part, such as congenital anus, congenital rectovaginal (urethral) fistula, congenital megacolon, etc. (B) external causes of anorectal diseases 1, dietary factors: In daily life, it is natural that dietary patterns or dietary varieties inevitably change. Such as the quality of food coarse and fine, change in the type of vegetables and the amount of increase or decrease, the amount of protein, fat, starch, fiber and other content, water intake, can directly affect the fecal composition, causing anorectal disease. Long-term alcohol or spicy food, because wine and spicy substances can stimulate the mucosa of the digestive tract, resulting in vasodilation, colon dysfunction, the incidence of anorectal disease increased significantly. 2, occupational factors: long-term standing or sedentary. Because of the upright or sedentary posture, the anorectum resides in the lower part of the body, the hemorrhoidal vein reflux is not smooth. 3, chronic diseases: such as long-term malnutrition, physical weakness, causing the anal sphincter relaxation and weakness. Long-term chronic bronchitis, emphysema, coughing and wheezing caused by the rise in abdominal pressure, pelvic stasis. Chronic hepatitis, hepatic steatosis, diarrhea, colitis, etc. are all triggers for the occurrence of anal diseases. Therefore, in the prevention should pay attention to the patient’s systemic state and take reasonable and effective preventive measures. 4, bad defecation habits: squatting position to read a book and newspaper when going to the toilet, resulting in squatting and prolonged defecation time, easy to cause stasis of blood in the anorectum and induce disease. Smoking when going to the toilet can buffer the brain’s defecation reflex, which is very easy to cause constipation. Excessive force during defecation, some people do not care whether the feeling of defecation is strong, blindly and constantly violently struggle, can only make the rectum anus and pelvic floor muscles increase unnecessary burden and local stasis, leading to the occurrence and development of disease. 5, defecation abnormalities: diarrhea and constipation are important factors in the pathogenesis of anal diseases. Constipation is the biggest bane, long-term retention of toxic substances in the rectum can not only induce rectal cancer, and the accumulation of feces, affecting blood circulation. The effort to solve the dry fecal mass will certainly put the anus under greater pressure, producing a series of pathological changes such as stasis, swelling and fissures. Diarrhea is often a clinical manifestation of colon disease, and diarrhea can also increase the chances of local infection in the anus, producing diseases such as anal sinusitis, inflammatory external hemorrhoids, and perianal abscesses. The symptoms of the disease 1, blood in the stool: can occur before or after the stool, or simple blood in the stool or mixed with feces and down. 2.Anorectal pain: Due to the rich nerves in the anus, the senses are sensitive, and pain or severe pain is easily occurred after stimulation, such as stabbing pain, swelling pain, burning pain, cramping pain, etc., which can occur during, after or at other times. 3, anorectal swelling: it is caused by rectal lesions stimulating the local symptoms. The main manifestation is that the lighter the local distension and fullness of the fall; the heavier the urgency, frequent toilet, after the heavy fall still, very painful. 4, anal mass prolapse: it refers to the protrusion or redundancy in the rectum or anal canal, prolapse through the anus, the lighter only in defecation out of the anus. In heavy cases, it can come out when the abdominal pressure increases, such as coughing, squatting and lifting with force. 5.Anal discharge: It can be discharged both from the fistula and from the anus, or from the perianal skin. 6.Anal itching: it is mostly due to the itching discomfort caused by the stimulation of the anus and the surrounding skin. 7, abdominal pain: abdominal pain in anal disease is mostly concentrated in the small abdomen and less abdomen, mainly caused by lesions or dysfunction of tissues and organs in the abdominal cavity and pelvis. 8, abdominal distension: lesions of the colon, rectum and anal canal can often cause abdominal distension and discomfort. 9, diarrhea: patients tend to increase the number of stools, thin feces or watery, can also see pus and blood. Third, the hazards of anal diseases 1, resulting in anemia: to hemorrhoids as the main symptom of patients, often appear anemic. If you don’t get timely treatment, as the amount of blood loss increases, you will appear pale, weak, dizzy, weak, and sudden standing after sitting and squatting for a long time can lead to deficiency or fainting. 2.Leading to skin eczema: Due to the prolapse of hemorrhoids and sphincter relaxation, mucus flows out of the anus to stimulate the skin, which leads to skin itching and anal eczema. 3, leading to rectal deterioration: hemorrhoids if not treated in a timely manner, the lesions continue to aggravate, so that the cells in the area of the lesion lesions, leading to the creation of rectal lesions. 4.Women with hemorrhoids can cause gynecological inflammation: If hemorrhoids bleed or become inflamed it often leads to a proliferation of germs that can cause various vaginitis, urethritis, cystitis, adnexitis and other urogynecological inflammatory diseases. 5, reduce the quality of life: if hemorrhoids bleeding or inflammation often leads to the proliferation of germs, leading to male inflammation, coupled with pain and discomfort, thus affecting the quality of life. Fourth, prevention 1, eat less high-fiber foods: such as potatoes, pasta, beans and vegetables such as cabbage, cauliflower, onions, they are easy to create gas inside the gut, which leads to the appearance of bloating. 2, do not eat indigestible food: fried beans, hard pancakes and other hard foods are not easy to digest, so they stay in the gut for a longer time, producing more gas and causing bloating. 3, change the habit of wolf swallowing: eating too fast or walking while eating and other bad habits, it will be easy to swallow a lot of air; in addition, commonly used straws to drink drinks will also make a lot of air dive into the stomach, causing abdominal distension. 4, overcome bad emotions: anxiety, worry, sadness, frustration, depression and other bad emotions may also weaken the digestive function, or stimulate the stomach causing too much stomach acid, the result will also make too much gas in the stomach, resulting in increased bloating. 5, pay attention to exercise: every day should adhere to about 1 hour of moderate exercise, not only to help overcome bad emotions, but also to help maintain the normal function of the digestive system. 6, moderate supplemental fiber food: high-fiber foods do not only lead to bloating, sometimes on the contrary, after the intake of high-fat foods, sometimes have the effect of reducing bloating. The reason is that high-fat food is difficult to be digested and absorbed, so it tends to stay in the gut for a long time, and once fiber is added, the blocked digestive system is likely to be unblocked quickly.
