The stool suddenly turned black. What's wrong?

The sudden blackening of stools may be caused by unreasonable diet, and may also be related to peptic ulcer, digestive tract malignant tumor and other diseases.

1. Unreasonable diet in a

short period of time leads to the accumulation of excessive oxidized iron elements in stools, which will cause sudden blackening of stools.

2. Peptic ulcer

Peptic ulcer mainly occurs in the stomach and duodenum. Patients do not pay attention to gastrointestinal bleeding in time, and black stools will occur.

3. Malignant

tumors in the gastrointestinal tract cause continuous infiltration of cancer cells around the lesions, which will cause bleeding and appear black stools.
