There are many causes of blood on toilet wipes, and the common causes are concentrated in the lower GI bleeding, followed by the upper GI, and a few are seen in systemic diseases. Lower gastrointestinal bleeding mainly includes hemorrhoids, anal fissures, rectal polyps, rectal cancer, etc. Upper gastrointestinal bleeding includes gastric and duodenal bleeding, etc. A. Lower gastrointestinal bleeding: 1. Hemorrhoids: Hemorrhoids are a relatively common clinical disease, which is due to constipation after drinking a lot of alcohol or eating a lot of chili peppers. When constipation is dry, the stool is easy to bruise the hemorrhoids, so you will find obvious blood on the paper after going to the toilet. Patients should change bad eating habits, increase the intake of fibrous food, but also through hot water sitz bath to improve local blood circulation; if the symptoms are more serious, you can use sclerotherapy under the guidance of a doctor, such as phenol vegetable oil, sodium cod liver oil acid, etc., but also through surgery to remove; 2, anal fissure: is due to long-term constipation, dry stool and other reasons resulting in the formation of ulcers after the skin layer of the anal canal under the dentate line is cracked The ulcer will be rubbed by the stool, leading to a small amount of blood on the paper when going to the toilet, or drops of fresh blood. The patient can take a warm bath with potassium permanganate after defecation to maintain local cleanliness, and severe symptoms can be treated through anal fissure removal; 3, rectal polyps: mainly due to abnormal cell proliferation in the rectum, resulting in redundant rectal mucosa, when these redundant by the friction of the stool, prone to bleeding phenomenon. Rectal polyps are usually treated through surgery, for smaller polyps can be treated through anal resection, for larger polyps can be treated through endoscopic trap removal to relieve the symptoms of bleeding; 4, rectal cancer: is a malignant tumor, its location mainly exists in the rectal part, the texture of the tumor is hard, which can easily lead to the rectal wall becomes stiff, pressure, resulting in the surface of the tumor The tumor is hard and can easily cause the rectal wall to become stiff and compressed, resulting in the surface of the tumor to break down and continuously ooze blood, which in turn results in blood on the paper when going to the toilet. The main treatment methods for rectal cancer include surgery, radiotherapy and chemotherapy, among which surgery is the main cure for rectal cancer, and the main methods include conventional open manual surgery, laparoscopic manual surgery and machine manual surgery, etc. Second, upper gastrointestinal bleeding: It is caused by various reasons such as bacterial infection or excessive secretion of gastric acid that destroys the surface mucosa of the stomach and small intestine, resulting in the formation of ulcers, which are too deep or too large causing bleeding, and when blood is discharged with feces, blood can appear on the stool paper. Examples include gastric ulcers, duodenal ulcers, and ulcerative colitis. Patients can use proton pump inhibitors to stop bleeding, inhibit gastric acid secretion, raise pH in the stomach, and promote clotting. Common drugs in this class include omeprazole, lansoprazole, pantoprazole, rabeprazole, etc. The above only lists some of the more common causes, there are also some people who have blood on the paper when going to the toilet due to blood in urine, vaginal bleeding, uremia, leukemia, etc. It is recommended that when bleeding symptoms are found, you should go to the hospital for examination in a timely manner, and actively treat the primary disease after clarifying the cause to relieve the bleeding symptoms so as not to cause adverse effects on the body.
