Black stool with blood

Introduction Gastrointestinal hemorrhage causes changes in fecal traits, which are black with blood. Gastrointestinal hemorrhage is a common clinical symptom. The digestive tract refers to the duct from the esophagus to the anus, including the stomach, duodenum, jejunum, ileum, cecum, colon and rectum. The upper gastrointestinal bleeding site refers to the esophagus, stomach, duodenum, upper jejunum, and pancreatic duct and bile duct bleeding above the ligamentous ligament. Intestinal hemorrhage below the ligamentous ligament is called lower gastrointestinal bleeding. The amount of blood loss is small, below 400ml, the blood volume is slightly reduced, and can be compensated by tissue fluid and spleen blood storage. The circulating blood volume can be improved within 1 hour, so there is no symptom.

Cause

1 upper gastrointestinal bleeding (see hematemesis).

2 small intestinal bleeding: such as intestinal tuberculosis, localized enteritis, acute hemorrhagic necrotic enteritis, small intestine tumor, intussusception and so on.

3 colon bleeding: such as dysentery, ulcerative colitis, localized enteritis, colon cancer and so on.

Followed by abdominal pain, mostly in the right upper abdomen. Occasionally constipation. Severe infections are often accompanied by nausea, vomiting, paralytic ileus, abdominal distension, electrolyte imbalance, dehydration, and even intestinal perforation, systemic failure, and death. Some acute patients can excrete squeaky, smoky white stools and even severe fat cramps. The cause may be related to malabsorption or rupture of the intestinal lymphatic vessels, and fat entering the intestinal lumen.

2, baby brown or dark green mucus:

The amount of feces is reduced to mucus, dark brown or dark green, which often occurs after indigestion and limited food intake. Diarrhea feces, excessive moisture in the feces or uneven fecal matter, egg-like soup, obvious astringency or a lot of foam or mucus, which indicates that the baby has diarrhea. The stool of the artificially fed child is green, indicating an increase in intestinal peristalsis or intestinal inflammation, as well as diarrhea.
