What is the matter with pale yellow stool

The color of stool can generally reflect the health condition of the human body to a large extent. For example, if the stool is dark yellow, it may be caused by malignant malaria, hemolytic cell infection or chemical poisoning. White or grayish white stools may be caused by problems such as gallstones and pancreatic cancer. In addition, green, light red, bright red, dark red and black stools are all abnormal.

Dark yellow:

It can be caused by congenital red blood cell defects, hemolytic bacterial infection, malignant malaria, blood transfusion with the wrong blood type, poisoning by certain chemicals or toxins, various immune reactions (including autoimmunity), etc.

White or off-white:

It indicates bile duct obstruction, possible gallstones, bile duct tumors or pancreatic head cancer. In addition, grayish white stools can also be seen after barium meal radiography, which is not physiological stool caused by disease.

green:

It is watery or pasty, has a sour smell and is foamy. It is often seen in diseases such as indigestion and intestinal dysfunction. If the green stool is mixed with pus, it is a sign of acute enteritis or bacillary dysentery. In addition, eating a lot of foods containing chlorophyll or high acidity in the intestines can also cause the stool to turn green.

Light red:

This type of stool is like meat washing water. It is most common in summer due to eating pickled foods contaminated by halophilic bacteria; it is common in diarrhea caused by Salmonella infection.

Bright Red:

Common in lower gastrointestinal bleeding. If the outer layer is stained with blood, the amount is small, and it is accompanied by severe pain, and the pain disappears after defecation, it is anal fissure; if the blood is bright red, the amount varies, or it is in the form of blood clots, attached to the outer layer of the stool and does not mix with the stool, and the blood or blood clots can be washed away with water, there may be internal hemorrhoid bleeding. If the blood is bright red and mixed with feces, it may be caused by intestinal polyps or rectal cancer or colon cancer.

Dark red:

Because blood and feces are evenly dark red, it is also called jam color, which is often seen in amoebic dysentery, colon polyps and colon tumors. Another situation is that normal people who eat excessive amounts of coffee, chocolate, cocoa, cherries, mulberries, etc. may also have dark red stools, which should be distinguished from the above diseases.

black:

Because it is the same color as asphalt on the road, it is also called tarry stool and is a common type of stool causing upper gastrointestinal bleeding. It includes duodenal ulcer, gastric ulcer, antral gastritis, wax prolapse, esophageal varicose vein rupture and bleeding in cirrhosis of the liver, etc. However, if you eat too much meat, animal blood, liver, spinach, take oral iron supplements, bismuth supplements, activated carbon, etc., your stool may also be black, so you should distinguish it. Use water to disperse the black stool. If it turns bloody, it is gastrointestinal bleeding.
