The probability of modern people suffering from various diseases is constantly increasing, among which blood in stool is also one of the diseases endangering our modern people's health.

Let me talk about it.

What reason is the frequency of defecation much and take blood again

First, if you take iron containing drugs or foods, iron containing multivitamins or iron supplement drugs, it is impossible for all iron to be absorbed, and a small amount of iron will be discharged through the intestines. At this time, the stool may contain dark brown spots, and the occult blood in the stool will be positive.

Second, if the small intestinal mucosa is damaged, there will be red substances in the stool, just like blood in the stool. Occult blood in the stool test is often positive; misuse of drugs or foreign bodies will cause damage to the intestinal mucosa, which will lead to bloody stool.
