Black and sticky stools may be caused by dietary factors, gastrointestinal bleeding, medication factors and other reasons.
1. Dietary factors: mainly caused by patients eating meat, animal blood products and green leafy vegetables. Usually, during the digestion of such meat and animal blood products in the gastrointestinal tract, a large number of red blood cells, proteins and fats remain undigested, resulting in dark and sticky stools.
2. Gastrointestinal bleeding: usually seen in moderate bleeding in the upper gastrointestinal tract, where a large amount of blood flows into the gastrointestinal tract and is thus digested by the gastrointestinal tract. Usually a large number of undigested red blood cells are black and sticky, thus leading to the phenomenon of black and sticky stools.
3. Drugs: mainly found in metal preparations, such as ferrous succinate, ferrous sulfate and medicinal charcoal, etc. Taking these drugs may lead to the phenomenon of black and sticky stools.
There are many other reasons for black and sticky stools, so it is recommended that patients seek medical advice in a timely manner to identify the cause of the problem under the guidance of a doctor and carry out the relevant treatment.
