What is the reason for the red water in the toilet after defecation?

After defecation, the toilet water is red, which may be caused by physiological factors, or may be caused by pathological factors such as hemorrhoids and anal fissure.

1. Physiological factors

If the woman is in physiological period, a small amount of menstrual blood will drip into the toilet during defecation, resulting in red toilet water after defecation, which is a normal physiological phenomenon.

2. Hemorrhoids

are caused by congestion and swelling of the anal canal and the lower rectal vein. When the patient defecates, the feces will rub against the hemorrhoids and cause it to break and bleed, which will also cause the toilet water to be red after defecation.

3. Anal

fissure is a disease caused by the longitudinal cracking of the entire skin of the anal canal. The patient will bleed locally, which will also cause the above symptoms.
