Why does water come out of diarrhea

Watery diarrhea is usually caused by a decrease in the ability of the colon to absorb water during diarrhea, and the water or digestive juices ingested in the gastrointestinal tract are not absorbed.
It is usually caused by acute gastroenteritis, food allergies, etc. This is mainly related to the intake of bacterially contaminated food or the patient’s allergy to ingredients in the food. Diarrhea is caused by an imbalance in secretion and absorption due to excessive secretion of water and electrolytes or suppressed absorption as a result of inflammatory stimulation of the intestinal mucosa.
For patients with severe diarrhea, antidiarrheal agents such as montelukast can be used for treatment, and patients who are severely dehydrated need to be rehydrated intravenously in a timely manner. For acute gastroenteritis caused by bacteria, patients can use levofloxacin, ciprofloxacin and other antibiotics for treatment. Diarrhea caused by allergies can also be treated with drugs such as loratadine and cetirizine.
Patients with diarrhea should rest more, avoid fatigue, and drink warm and lightly salted water appropriately to avoid dehydration and electrolyte disorders. There are many causes of diarrhea, it is recommended that patients seek timely medical attention to clarify the cause of diarrhea and timely treatment to avoid aggravation of symptoms.
