Blood in stool looks different depending on how early it enters the digestive tract—and thus how much digestive action it has been exposed to—and how much there is. The term can refer either to melena, with a black appearance, typically originating from upper gastrointestinal bleeding; or to hematochezia, with a red color, typically originating from lower gastrointestinal bleeding.

Bromelain extract is a mixture of protein-digesting (proteolytic) enzymes and several other substances in smaller quantities. The proteolytic enzymes are sulfhydryl proteases; a free sulfhydryl group of a cysteine amino acid side chain is required for function. The two main enzymes are: Stem bromelain – EC 3.4.22.32; Fruit bromelain – EC 3 ...
Melena is a form of blood in stool which refers to the dark black, tarry feces that are commonly associated with upper gastrointestinal bleeding. [1] The black color and characteristic strong odor are caused by hemoglobin in the blood being altered by digestive enzymes and intestinal bacteria.

Blood in stool: Red flags There are some symptoms that raise suspicion when they accompany blood in the stool, Dr. Bulsiewicz points out. These can include multiple bowel movements in a row with ...
The presence of bright red blood in stool, known as hematochezia, typically indicates lower gastrointestinal bleeding. Digested blood from the upper gastrointestinal tract may appear black rather than red, resulting in "coffee ground" vomit or melena. [2] Other signs and symptoms include feeling tired, dizziness, and pale skin color. [18]
The bottom line Most vitamins are considered safe for up to two years past their expiration date (unless they contain mold), but may become less potent over time.
Depending on the surface area and depth of the wound, bromelain blood serum concentrations of no more than 40 μg/ml are expected, with peak concentrations reached after 2 to 4 hours. The terminal half-life varied between 8.5 and 19.9 hours in studies. These data have been obtained from 15 patients with comparatively shallow wounds. [5] [10]
