The anorectum is the end of the human digestive tract. It is through the rectum and anus that the undigested parts of the diet, dead bacteria in the intestine and some impurities are excreted. From the point of view of intestinal physiology, the anorectum is characterized by smooth and harmonious; smooth and unobtrusive discharge of stool without other discomfort is a very important part of our health. The Chinese medical classic “Huangdi Neijing? The six sections of the Tibetan elephant theory, “the six internal organs, the transfer of things and not hidden, so the real and can not be full”, “six internal organs to pass for the use of”, it is this meaning. Therefore, the rectum and anus is an extremely important organ in the human body, but also an important precision control system, we need to pay attention to protect at all times. Those who think that the rectum and anus is dirty, do not bother to protect the view is wrong, should be corrected. In fact, the human body’s rectum and anus are more likely to be irritated and sick. The folk proverb “nine hemorrhoids for ten men”, “nine hemorrhoids for ten people”, “ten hemorrhoids for ten women”, refers to the high incidence of anorectal diseases. As the end of the digestive tract, the rectum and anus are dealing with an extremely large number of bacteria every moment. According to Professor Chizu Mitsuoka, president of the World Society of Microecology, our intestines are “inhabited by an average of one hundred trillion bacteria”. Foreign studies also show that in an individual on a typical Western diet. Bacteria account for 40% to 50% of solid stool. Therefore, the internal environment of the colon is delicate and fragile, and a small injury brought about by carelessness may lead to serious consequences. When various causes of local congestion, edema and inflammation of the rectum and anus in daily life, if you do not raise awareness, prevention or treatment in a timely and reasonable manner, you will gradually aggravate the condition and delay the disease, and even repeated inflammation, which brings trouble to medical treatment and aggravates your own pain. But despite such a high incidence of anorectal disease and such easy conditions, we can still find reasonable and effective ways to prevent it; and it is simple, time-saving and cost-saving prevention. The “no disease prevention, disease prevention” has been summarized as one of the three characteristics of Chinese medicine, summarized a set of effective methods to prevent and control anorectal diseases. The first is to keep clean, wash and change often. This is an effective way to prevent the occurrence or recurrence of anorectal disease, simple and easy to do, but also the patient friends can do on their own. At the same time, maintaining local cleanliness is also of great benefit to our overall health and can reduce the prevalence of dysentery and intestinal parasitic diseases. Therefore, it is placed in the first place of precautions as a reminder. The approach to cleaning, which we favor, is to take advantage of all convenient conditions and to do it at any time. Any method that can keep the anal area clean, dry and comfortable without damaging the local skin is feasible. However, the most recommended method is to use water for flushing (cleaning). The conditions are convenient for the use of warm water, special spare equipment; conditions do not allow the direct hand to scoop up water to clean, and gently dip dry after washing. The water can wash away the accumulated fecal debris in the anal skin folds, and also clean the local sweat (there are both large and small sweat glands around the anus) and the sebum secreted by the sebaceous glands. Warm water can make the local sweat glands, hair follicles and sebaceous glands open and not cause disease due to poor secretion and discharge; at the same time, it promotes local blood circulation and improves local immune regulation. Although cool water is not as good as warm water, but also can play a better cleaning effect. If you do this, you can very effectively prevent and reduce the chance of local infection and inflammation, which can effectively prevent anal eczema, anal itching, anal sinusitis, hemorrhoids, etc. It is also a powerful measure to prevent the occurrence or recurrence of anal fistula and perianal abscess. If you can combine this with local anal rubbing, it can be even more effective in preventing anal fissures, thrombosed external hemorrhoids, post-operative scar discomfort or poor softening, and is also beneficial in stopping the further development of anorectal prolapse. It is important to note that the water temperature should not be too high, otherwise it will not only burn the anal skin, but also cause local congestion, which will have the opposite effect of treatment and aggravate the discomfort. In addition, do not use irritating lotions such as disinfectant wipes to clean the anal canal; these disinfectants can irritate the mucous membrane and cause itching, burning and other discomfort to those with allergies. It is also important to note that if you have to use toilet paper to wipe after a bowel movement, you should always choose soft, flake-free paper towels. This will not only clean the anus, but also not damage the local skin and mucous membrane. The requirement to wash and change frequently is not only for the anal area, but also for the underwear. In addition to dry and clean underwear, you should also choose cotton material; do not wear chemical fiber underwear. Especially allergic, anal itching, anal eczema patients should pay more attention. The second is to always have medicine on hand, so that you can be prepared for any problems. This is the method used when rectal-anal discomfort is already present. Prevention and treatment of inflammation is necessary and effective to prevent further development of more troublesome anorectal diseases. This has been well proven through a large number of clinical medical practices. Then readers should pay attention when they feel the following localized discomfort in the anus: itching, pain, blood in the stool or blood in the stool, burning sensation in the anus, unpleasant stool, dry stool, time-consuming and laborious defecation after stool, pus or overflow, and anal dampness. These symptoms are the common clinical manifestations of several common anorectal diseases, and their appearance mostly indicates the unhealthy state of the anorectum; and most of these unhealthy states are caused by various acute and chronic inflammatory diseases in the anorectum. If not taken seriously and neglected, these inflammations and discomforts will continue to be difficult to eliminate and even worsen, eventually leading to more serious anorectal diseases. These discomforts are mostly due to unhealthy lifestyles such as frequent late nights, spicy food, alcoholism, insufficient fiber intake, too little food, poor bowel habits, excessive life and work stress, too frequent sex, etc. For local discomfort with clear causes, we should recognize the adverse effects of these bad habits and overcome and correct them; at the same time, we should actively treat the symptoms and not let them develop on their own. For self-control method, we suggest: improve the structure and amount of diet, pay attention to rest and avoid alcohol during the existence of anal discomfort. At the same time, you should follow the first method above to douche and sitz bath the anus, and use medication. Medicines can be kept at home for all kinds of emergencies. We recommend several medications commonly used in anorectal medicine: hemorrhoidal suppositories; tylenol suppositories. In particular, the suppositories are worth mentioning. The suppositories are simple to use, easy to carry, easy to operate and at the same time the drug can be applied directly to the local area, increasing the local concentration and duration of action, and avoiding the decomposition and metabolism of the drug by the liver when the drug is taken orally (medically known as “first pass elimination”) and weakening the effect of the drug. By timely intervention of local inflammation and prevention, many anal discomforts can be relieved within three days. If the symptoms are not relieved, or even aggravated, it is beyond the power of local medication, so you should go to the hospital to find out the cause and take appropriate treatment. In this way, we can not only waste time but also have a clear purpose, so that the diagnosis and treatment of the disease can be done with half the effort. In short, the above two points of attention are valuable lessons learned from clinical work. One for a rainy day and one for prevention; the two-pronged approach will certainly serve as an inspiration for the health of our readers and friends. However, prevention is not the same as cure, we suggest, but also early to the hospital, timely and effective treatment, so as not to delay the disease.
