Stool is a metabolite in the intestine. It is formed by , large intestine, and then excreted from the body through the anus through the rectum. This process can help the body detoxify.
For healthy people, the color of the stool is generally light yellow, and there is no blood or pus in the stool. However, in daily life, many people will experience blood in their stools when defecate. This phenomenon is called blood in stools .
If this phenomenon occurs frequently, you must be highly vigilant, which is generally related to suffering from various diseases. So, what are the reasons for frequent blood in stools?
1. hemorrhoids
No matter what period of internal hemorrhoids or mixed hemorrhoids , it will cause stool bleeding. When the patient defecates, blood will adhere to the surface of the stool, or after the stool is discharged, some blood will drip from the anus.
There will also be obvious pain in the anus during defecation, and the skin in the anus will also experience repeated itching and sticky feeling.
2. Anal fissure
Anal fissure is a particularly common anorectal disease, which refers to a phenomenon in which the skin of the anal canal is longitudinally cracked and forms small ulcers. Once anal fissures appear, every time the patient defecates, severe anal pain will occur due to the stool stimulation of the damaged mucosa, which will radiate to the perineum and the inner thighs.
In addition, bright blood will appear on the surface of the stool, but the amount of bleeding is not very large. At the same time, the patient will also have constipation or itchy sensation in the anus.
3. Ulcerative colitis
Ulcerative colitis is a nonspecific inflammatory disease of the intestinal tract, which generally occurs in the colon and rectal areas. Once ulcerative colitis occurs, the patient will experience repeated diarrhea, some pus in his stool, or bloody stool in his daily life. Patients may also have abdominal pain, decreased appetite, and abdominal distension.
IV. intestinal polyps
Intestinal polyps refer to some raised lesions growing in the intestinal cavity. Once a long polyp grows, the patient will not experience obvious discomfort in the early stage. If the polyp gradually increases in size, some bright red blood will appear on the surface of the stool when the patient defecates.
It also causes repeated diarrhea, constipation, or alternating diarrhea and constipation, and it may be accompanied by abdominal pain, indigestion and anemia.
5. gastric cancer
For patients with gastric cancer, due to the fact that upper gastrointestinal bleeding is not very serious, the blood flow rate is relatively slow, and it will be oxidized into black in the intestine, causing the patient to expel black stool.
But if the amount of bleeding is large, the patient will experience obvious bleeding stools during defecation. It will also be accompanied by repeated indigestion, abdominal distension and pain, as well as weight loss and rapid appetite loss.
6. Intestinal cancer
When suffering from intestinal cancer, the tumor itself will rupture or cause bleeding in the intestinal mucosa, and the amount of bleeding will be greater. When the patient defecates, blood will be mixed in the bowel movement.
It is generally accompanied by a series of symptoms such as thinning stool, repeated abdominal distension, abdominal pain, or constipation, diarrhea, body weight loss, increased bowel movements, and incomplete bowel movements.
In short, there are many causes of bleeding stools, but they are generally related to the above 6 diseases. In addition, if you suffer from some infectious intestinal diseases, such as amoeba enteropathy and bacterial dysentery , you will also experience bloody stools.
