Lactose intolerance is very common. Every 1 in 3 people have this condition which lactase, a sugar that is a constituent of milk and other dairy products is not produced in adulthood. So, when they consume anything that consists of a lot of lactase, like milk, it results in excess gas production, stomach aches and diarrhea.
Majority of humans stop producing insignificant amounts of lactase between the ages of 2-5. So, by the time we reach adulthood, the lactase production keeps reducing considerably with each passing year.
When a lactase intolerant person consumes milk, the lactase in milk remains uncleaved and unabsorbed. Since, lactose cannot pass easily through the walls of the intestine and thus remains in the intestine. Soon, bacteria adapt to lactose and produce profuse amount of gas.
