Diarrhea, commonly known as diarrhea, is one of the most common symptoms of the digestive tract, everyone has experienced. The definition of diarrhea of science is significantly more than normal habit of defecation frequency, stool thin, water increased, usually containing undigested food or pus and mucus. Diarrhea is often accompanied by abdominal pain, defecation urgency, tenesmus symptom. The direct cause of diarrhea is the rapid intestinal peristalsis, water absorption decreased, leading to the formation of feces is not rushed out of the body in vitro.
Diarrhea has brought trouble to our life, but from another perspective, diarrhea is a self protective mechanism of the body, from the most common Chihuaiduzi diarrhea is mainly because intake have not clean food pathogenic bacteria breeding, was found the body will start the defense system, to accelerate the peristalsis these harmful toxic substances discharged.
The pathogenesis of diarrhea is very complex, there are some factors from the common causes of reciprocal causation, can be summarized as follows.
Dynamic diarrhea: refers to the hyperfunction of intestinal peristalsis caused by intestinal digesta retention time, has not been fully absorbed due to diarrhea, such as irritable bowel syndrome, hyperthyroidism, gastrointestinal dysfunction.
Intestinal inflammation: it can be because of some infectious diseases such as viral gastroenteritis, bacterial gastroenteritis, intestinal tuberculosis; also can be a number of non infectious disease, ulcerative colitis, Crohn's disease, ulcerated tumor can make the inflammatory exudate increased due to diarrhea, some gastrointestinal endocrine tumors such as gastrinoma caused by diarrhea also belong to secretory diarrhea.
Osmotic diarrhea is caused by an increase in intestinal permeability, blocking the absorption of water in the intestine. Taking salt laxatives, lactulose, mannitol and other laxative is the principle. Some people drink milk diarrhea, but also for this reason, milk contains lactose, they cannot digest lactose, the formation of intestinal permeability, it is like drinking laxatives. In addition the digestive function will not occur this kind of diarrhea: due to chronic pancreatitis, chronic atrophic gastritis, after subtotal gastrectomy, gastric juice, bile and pancreatic diseases and reduce secretion of digestive juice, food can not fully digest the cause intestinal hypertonic take plenty of water to the colon had diarrhea.
Other: because the absorption area of the intestinal mucosa or reduce the absorption of obstructions, such as intestinal surgery, malabsorption syndrome, celiac disease etc..
Although diarrhea side, have protective function but if diarrhea is very serious when, or overkill, are harmful to people and did not stop, which is particularly reflected in the children, because the immune system and intestinal function development has not been perfect, most likely because of diarrhea in children due to dehydration. Mild to moderate dehydration can be supplemented by oral rehydration salts and electrolytes. And long-term diarrhea can lead to malnutrition.
Some of the need to guard against diarrhea
If the red, dark red or bloody diarrhea with tarry black will be especially vigilant, the diarrhea is caused by gastrointestinal bleeding, if blood loss will cause dizziness, even shock, at this time should be timely hospital. Similarly, if diarrhea accompanied by fever, abdominal pain, diarrhea, vomiting, jaundice, fatigue and other conditions should be vigilant, these cases of diarrhea is often not functional due to the cause of the need to find and treat.
Some common misconceptions about diarrhea
Antidiarrheals: many people in diarrhea is to use angidiarrheal most probably it did not actually happen, to the immediate termination of diarrhea, not knowing that it is covered condition, delayed treatment practice. If because of the infection of diarrhea, the diarrhea is a kind of human means of defense, toxic and harmful substances will be discharged as soon as possible, in this case eat angidiarrheal thankless.
Antibiotics: there is a common misunderstanding is that the diarrhea went to the drugstore to buy what "norfloxacin" and other antibiotics, diarrhea caused by bacteria that is, the use of antibiotics to kill bacteria is safe". In fact, our stomach acid will kill most bacteria, and the intestine has normal flora can resist bacteria, generally eat unclean food because of diarrhea is not caused by the bacteria themselves, but these toxins produced by bacteria. The antibiotic itself is for the weak resistance of the auxiliary body to kill bacteria, the bacteria produce toxins is of no use, so that the use of antibiotics is not appropriate in most cases of diarrhea, and long-term indiscriminate use of antibiotics will disrupt the intestinal flora balance, it will lead to intractable diarrhea. There are many reasons to cause diarrhea, diarrhea patients find an antidote against the disease, and not blindly.
What is the cause of diarrhea, what type of diarrhea, being able to judge or to a regular hospital for examination, the unauthorized use of antibiotics, antidiarrheal drugs may have no effect, but also a waste of money, the greatest harm is caused by drug abuse damage and delay.
