People with lactose intolerance are unable to digest lactose, the main carbohydrate in dairy products. This occurs because the small intestine stops creating a sufficient amount of the lactase enzyme, which is needed to break down lactose.
Several types of lactose intolerance exist and may be caused by different factors. However, all lactose intolerance is characterized by a deficiency in lactase.
If you have had a resection like me, you might find you are bloated after having dairy. Also, if your gut isn't working properly, you might not be producing enough lactase.
If you do stop having dairy, remember to replace the vitamins and minerals found in dairy like the B group vitamins, calcium and vitamin D.
