Lactose intolerance is the inability to produce enough lactase to digest the diasacchride lactose
Lactose can be found in milk or any diary products. It can be hydrolysed by the enzyme lactase.
Babies have a large amount of lactase as milk is their main diet. However the amount of lactase reduces as less milk consumed
In some people the reduction in lactase is so great that they produce very little or no lactase. As a result these peop;e are unable to digest the lactose they consume but however they can they van take either lactase tablets or add lactose droplets or consume lactose free products.
A lactose intolerent person may have different symptoms such as
- abdominal cramp
How diarrhea works
Undigested Lactose cannot be absorbed.
This lowers the water potential of the lumen
The water potiential in the lumen is lower than the water potiential in the blood/cell
Therefore water moves into the lumen by osmosis
Resulting in diarrhea
