What is diarrhea?
Diarrhea is children defined as increased total daily stool output. It is usually associated with an increase in the water content of stool. The normal stool output in a toddler is 5-10 g /kg /day. A toddler is said to be having diarrhea if the daily stool output is more than 10g per kg body weight. It is also defined as loose, watery, unformed stools occurring more than three times in a day. If a toddler occasionally passes loose stool or passes stool more frequently which are well formed it is not called diarrhea.
Types of diarrhea
Based on the mechanism, diarrhea in toddlers is broadly classified in to the following groups.
Osmotic diarrhea – This is caused by presence of substances which are nonabsorbable in the gastrointestinal tract. The substance which is not absorbed results in water drawn in to the lumen of the gastrointestinal tract resulting in diarrhea. Some of the causes of osmotic diarrhea are:
- Lactose intolerance
- Intake of carbonated fluids
- Intake of sorbitol, magnesium hydroxide
Secretory diarrhea – In this type of diarrhea certain factors act on the intestinal wall and stimulate them to secrete water in to the lumen. Some of the causes of secretory diarrhea are:
- Bacterial infections - Cholera
- Viral infections - Rota virus
- Others – Bile salts, hormone (gastrin, vasoactive intestinal polypeptide) induced
There are a few simple methods to find the type of diarrhea that the toddler is suffering from. It is osmotic diarrhea:
- If there is improvement in symptoms with fasting
- If the stool test positive for reducing substances
- If the diarrhea is of small volume (less than 200 ml per day)
