Bile acid malabsorption (BAM), known also as bile acid diarrhea, is a cause of several gut-related problems, the main one being chronic diarrhea.It has also been called bile acid-induced diarrhea, cholerheic or choleretic enteropathy, bile salt diarrhea or bile salt malabsorption.
It is commonly found when the ileum is abnormal or has been surgically removed, as in Crohn's disease, or cause a condition that resembles diarrhea-predominant irritable bowel syndrome (IBS-D). This condition of bile acid diarrhea/ bile acid malabsorption can be diagnosed by the SeHCAT test and treated with bile acid sequestrants .
The basic unit of the Reactome database is a reaction; reactions are then grouped into causal chains to form pathways [115] The Reactome data model allows us to represent many diverse processes in the human system, including the pathways of intermediary metabolism, regulatory pathways, and signal transduction, and high-level processes, such as ...
In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway
Atypical HUS (aHUS) represents 5–10% of HUS cases [5] and is largely due to one or several genetic mutations that cause chronic, uncontrolled, and excessive activation of the complement system, [5] which is a group of immune signaling factors that promote inflammation, enhance the ability of antibodies and phagocytic cells to clear microbes ...
Carcinoid syndrome is a paraneoplastic syndrome comprising the signs and symptoms that occur secondary to neuroendocrine tumors (formerly known as carcinoid tumors). [1] The syndrome is caused by neuroendocrine tumors most often found in the gut releasing biologically active substances into the blood causing symptoms such as flushing and diarrhea, and less frequently, heart failure, vomiting ...
The signs and symptoms of protein losing enteropathy include diarrhea, fever, and general abdominal discomfort. [4] Swelling of the legs due to peripheral edema can also occur; however, if the PLE is related to a systemic disease such as congestive heart failure or constrictive pericarditis, then these symptoms could be due directly to the underlying illness.

The disequilibrium caused by these changes often causes withdrawal when the long-term use of a drug is discontinued. Upregulation and downregulation can also happen as a response to toxins or hormones. An example of upregulation in pregnancy is hormones that cause cells in the uterus to become more sensitive to oxytocin.
