Diarrhea is the condition of at least three defecations each day.
The following classification is proposed:
(1) acute - less than 14 days in duration
(2) persistent - more than 14 but less than 30 days in duration
(3) chronic - more than 30 days in duration
Fructose malabsorption | |
The ingestion of large amounts of fructose may induce diarrhea in patients with fructose malabsorption. |
|
Glucose-Galactose Malabsorption | |
Diarrhea manifests within the first weeks of life and causes severe life threatening dehydration unless glucose and galactose are eliminated from the diet. |
|
Histamine Intolerance | |
In patients with histamine intolerance diarrhea manifests after the ingestion of greater amounts of biogenic amines. |
|
Lactase deficiency | |
In patients with congenital lactose intolerance, diarrhea manifests with breast feeding. |
|
Adult type lactose intolerance | |
In patients with adult type lactose intolerance, diarrhea after the ingestion of milk and other lactose containing products becomes apparent with increasing age. |
|
ATTR amyloidosis | |
Diarrhea and obstipation can alternate. They are the result of autonomous polyneuropathy. |
|
Trehalase deficiency | |
Diarrhea in patients with trehalase deficiency manifests after the ingestion of greater amounts of trehalase, predominantly in young mushrooms. |
