The causes of blood in stool in prolonged squatting are mainly considered to be related to upper gastrointestinal tract diseases, lower gastrointestinal tract diseases and systemic diseases.
1. Upper gastrointestinal diseases: esophageal cancer, peptic ulcer, gastric cancer and other diseases will lead to swelling and congestion of the affected area and thinning of the skin, while squatting for a long period of time, the pressure in the abdominal cavity increases, which will easily cause an acute attack, resulting in ulceration and bleeding of the affected area, and then blood in stool will appear.
2. Lower gastrointestinal diseases: such as colon cancer, proctitis, hemorrhoids, anal fissure and other diseases, in the state of squatting for a long time, the abdominal pressure increases, the anal pressure increases, which can also lead to intestinal bleeding or anal rupture and bleeding, which triggers blood in stool.
3. Systemic diseases: such as hemophilia, sepsis and other diseases, can also lead to the symptoms of blood in stool.
When the symptoms of blood in stool appear, it is suggested that patients should consult a doctor in time, have a systematic examination to make a clear diagnosis, and follow the doctor’s instructions to carry out the corresponding treatment, so as to avoid delaying the condition.
