What is the reason for black stool after eating pig blood

After eating pig blood, black stool may be caused by increased iron content, gastritis, gastric ulcer and other reasons.

1. Increased iron content

Pig blood is rich in iron. When eating a large amount of pig blood, the iron content in the body will increase. Iron combines with gastric acid to form a black substance, which leads to black stool.

2. Gastritis

When the stomach tissue of the patient is stimulated by inflammatory substances, it will cause bleeding symptoms, resulting in patients with bloody stools after eating pig blood.

3. Gastric ulcer

Ulcerative damage to the stomach tissue will lead to bleeding. Blood will be partially decomposed under the action of gastric acid to form black stool.

It is recommended that patients with black stool symptoms should actively seek medical examination to exclude discomfort caused by pathological reasons.
