4. Lactose Intolerance

In order for the body to properly digest lactose, the type of sugar found in dairy products, an enzyme called lactase is produced. Lactose intolerance results when the body isn’t able to produce enough lactase to break-down milk into its simplest form, causing bowel irritation. This irritation of the digestive tract can present with different symptoms such as abdominal pain, cramps, nausea, bloating, diarrhea and vomiting, and discomfort.
