I feel that the stool is not clean, or have a bowel movement, there is a foreign body feeling at the anus, and the feeling of falling …… these feelings make people really uncomfortable, always want to go to the toilet squatting, but no matter how squatting, can not be discharged, really distressing. This is likely to be a sinusitis in the play. Sinusitis! For most people, it is still a relatively new term. In fact, it is one of the more common anorectal diseases, as the name implies, is the anal sinus inflammation. To know what sinusitis is all about, we have to start with the anatomical structure of the anal sinus. The “anal sinus” is shaped like a funnel anal sinus, a body tissue that grows near the anus, located at the junction between the anal skin and the intestinal mucosa, is an “easily injured” weak link. Why is that? Because of the large diameter of the rectal mucosa and the small diameter of the anal canal skin, the junction of these two parts will form many folds, which also form the anal sinus tissue. The sinus tissue is open upwards, like the funnel used in life. It normally secretes some fluid to lubricate the intestinal tract, ensure the smooth passage of stool, and protect the rectum. The opening of the anal sinus is an anatomical defect, if the stool is thin, or fall into the remnants of excrement, it is difficult to discharge by gravity, and over time, it is naturally easy to inflammation. Theoretically, the special structure of the anal sinus causes everyone to have the above situation, but why not everyone will get anal sinusitis? This has a lot to do with the body’s immunity. When there is something dirty in the anal sinus, those with good immunity will gradually absorb the waste. If you happen to stay up late, get sick, etc., the immunity decreases and you are naturally prone to inflammation. Therefore, the most effective way to prevent anal sinusitis is – to boost your own immunity. Make sure you sleep, don’t stay up late, eat less stimulating food, don’t drink alcohol, eat less chili, etc. Of these, getting enough sleep is the most important. Did you know that many diseases are caused by lack of sleep, such as the most common constipation and hemorrhoids. If the inflammation develops locally in the anus and the condition is severe, a perianal abscess can occur. If there is inflammation all around the anal sinus and the onset of the process is not very acute, it is known as anal sinusitis in clinical medicine. How can I judge myself? There is a foreign body feeling at the anus, as if there is something there; you always want to defecate, but you can’t do it no matter how you squat; you have a strong feeling of falling at the anus. If you have the above three feelings, it is likely that you already have anal sinusitis. It is recommended to go to the hospital as soon as possible to check, early detection, early treatment.
