Bacterial diarrhea will present with nausea, vomiting, abdominal pain, bloating, increased frequency of stools, mucous pus and blood stools, etc. Bacterial enteritis affects the functioning of the digestive system leading to an increase in the intestinal pressure, so the food in the stomach is not able to be emptied into the intestinal system, and it will be excreted by means of nausea and vomiting. Bacteria will violate the intestinal mucosa and cause spasmodic contraction of the intestinal system, so most patients will experience abdominal pain. Since the function of the intestines is affected, they are unable to absorb the nutrients from the food, so the patient will be accompanied by a feeling of bloating. Patients will also have electrolyte disturbances as the food is excreted as it is and the nutrients and water in it are not absorbed. The frequency of bowel movements will also be more frequent, even up to a dozen times a day. When the condition of bacterial enteritis worsens, it will also lead to intestinal mucosa detachment and necrosis, so some patients will be accompanied by mucus, pus and blood stools.
