If the patient is of weak immunity then the severity of disease is high. Children below the age of 5 are more prone to suffer from this infection as they have low immunity make up of the body.

The invading bacteria when enters the gastric tract settle there, and colonize and adhere to walls of gastric tract lead to mucosal wall invasion and destruction and produce enterotoxin production, ultimately these toxins leads to a destruction of a tract.

Due to this destruction process by bacteria secretions from intestinal tract increased and absorption of food decreases.

During this time of action of bacteria absorption of the fluids by intestine walls also decreased and leading to loss of electrolytes and nutrients and also causing dehydration.

Small intestines are the major part of a body which helps in fluid absorption but when this wall is going to be destroyed fluid is not absorbed and due to this stools are loose.

Gastroenteritis occurs in those patients who suffer from slow bowel movements i.e. are motility is less; it leads to colonization of pathogens.

The part of the bowel which is more commonly affected is proximal small intestines. This part is highly motile for removal of pathogens from intestine but when the functioning of this part is lost due to any underlying disease.

The pH of stomach and intestines is acidic in nature. This acidic pH is the primary defense of the body against the pathogens entering the gastric tract.

When this pH level of gastric tract changes from acidic to alkaline and this transformation of acidic to alkaline state is due to achlorhydric states ( i.e gastric surgery, antacids, the decrease in colonic anaerobic bacteria), then this defense is lost and pathogens invade mucosal tract directly and cause gastroenteritis.
Who Are Infected?
