Starch-based oral rehydration solutions

Some research suggests that this reduces stool formation (i.e. reduces the amount of liquid expelled from the body) in cholera cases, compared to standard oral rehydration solution recipes.

A mechanism for this is that nonabsorbed carbohydrates produce short-chain fatty acids in the colon, which enhance sodium absorption.

• Reduced osmolarity oral rehydration solution

• Rice-based oral rehydration solution for treating diarrhoea.
• Amylase-resistant starch plus oral rehydration solution for cholera.
