Women have blood in their stool and urine

After we eat, we need to excrete it, and the main functions of excretion are defecation and urination. Normally, people defecate and urinate every day. If the food they eat is messy or their diet is irregular, problems may easily arise in the intestines and the excretion function may not function on time. For example, some female friends find that there is blood in their stool and urine. What is going on?

Blood is discharged from the anus and the stool is bright red, dark red or tarry (melena) in color, which is called hematochezia. Blood in the stool is just a symptom, not a disease. Blood in the stool is more common in lower gastrointestinal bleeding, especially bleeding from colon and rectal lesions, but it can also be seen in upper gastrointestinal bleeding. The color of blood in the stool depends on the site of gastrointestinal bleeding, the amount of bleeding and the time the blood stays in the gastrointestinal tract. Blood in the stool accompanied by bleeding in the skin, mucous membranes or other organs is often seen in blood system diseases and other systemic diseases, such as leukemia, disseminated intravascular coagulation, etc.

Clinical manifestations

1. Bloody stool

Most of the time it is acute (immediate) bleeding, and the blood flows out of the blood vessels and is discharged through the anus with feces in a short time, or flows out directly after defecation. The appearance of the blood flowing out is similar to that of bleeding from external injuries, and its color is bright red, purple red, or dark red. It can coagulate into blood clots after a while. Common in the following diseases:

(1) Hemorrhoids

Internal and external hemorrhoids of all stages and mixed hemorrhoids can cause bleeding in the stool, usually with fresh blood in the stool or blood dripping after defecation. External hemorrhoids generally do not cause bleeding in the stool.

(2) Intestinal polyps

It is painless stool bleeding. Bleeding occurs during bowel movements and stops after bowel movements. The amount of blood varies. Generally, the blood does not mix with the feces. However, if the polyps are located high and the number is large, they may be mixed with the feces.

(3) Rectal prolapse

Bleeding during bowel movements may occur after a long illness.

(4) Anal fissure

Blood in the stool: the bleeding pattern is blood on one side of the stool surface, which is not mixed with the stool. Some patients have blood dripping after defecation.

2. Bloody stool with pus/mucus

That is, the excreted feces contains both pus (mucus) and blood. Purulent (mucous) and bloody stools are often seen in tumors and inflammation in the rectum or colon. The following diseases are common:

(1) Rectal cancer

The blood is fresh or dark red, and there may be mucus in the stool. Blood, mucus and stool are often mixed.

(2) Colon cancer

As the disease progresses, bloody stools gradually appear, mostly containing pus or mucus, and the blood is darker in color.

(3) Ulcerative colitis

Mucus or bloody stools, accompanied by left lower abdominal pain or lower abdominal pain.

(4) Intestinal infectious diseases

Such as bacterial dysentery, amoebiasis, etc.

3. Black stools

Also known as tarry stools, the stools are black or brownish black. It is one of the most common symptoms of upper gastrointestinal bleeding. If the amount of bleeding is small and the bleeding rate is slow, the blood stays in the intestine for a longer time and the feces discharged is black; if the amount of bleeding is large and the bleeding time in the intestine is shorter, the discharged blood is dark red; if the amount of bleeding is particularly large and is discharged quickly, it may also be bright red.

4. Occult blood in stool

Small amounts (trace amounts) of gastrointestinal bleeding will not cause changes in stool color and will only show a positive result in the fecal occult blood test, which is called occult blood in stool. All diseases that cause gastrointestinal bleeding can cause occult blood in the stool, the most common of which are ulcers, inflammation and tumors. A fecal occult blood test detects small amounts (trace amounts) of blood in the stool. Early fecal occult blood tests for intestinal polyps (cancer) may be positive. Regular fecal occult blood testing is an important way to screen (primary screening) for colorectal tumors.
