Why do many people have stomach aches after drinking milk?

Milk is a nutritious food that is good for health, however, many people often have problems when drinking milk such as stomachache, bloating, nausea, and diarrhea. Nutritionist Nguyen Thu Ha - Nam Sai Gon International General Hospital - said that there are many causes that can cause stomachache when we drink milk.

Drink milk when hungry

When milk protein enters the stomach, it will be broken down into amino acids for the body to absorb easily. However, when the stomach is empty, the process of breaking down protein into amino acids cannot be performed. At this time, the amount of protein supplied to the body cannot be absorbed and will be pushed into the colon to be converted into toxic compounds, causing many people to have stomach aches.

Lactose intolerance is also a cause of stomach pain after drinking milk.

Poor quality or expired milk

Milk that is not of good quality, milk that is not hygienic due to violations of production and storage procedures, or milk that has expired, etc., contains toxins and bacteria that are harmful to the digestive system. When consumed, it can cause food poisoning, leading to diarrhea after drinking milk.

Lactose intolerance

Lactose intolerance occurs when your body does not produce enough lactase, so it cannot break down and digest the lactose sugar in milk and other dairy products. This condition often causes stomach upset and symptoms such as: abdominal pain when drinking milk, bloating, diarrhea, cramps and flatulence after eating or drinking dairy products containing lactose. However, symptoms only occur half an hour to a few hours after drinking milk.

Milk allergy

Milk allergy is an abnormal response of the body's immune system to milk and products containing milk. Common signs and symptoms of milk protein intolerance or lactose intolerance include digestive problems, such as bloating, gas, or diarrhea, after drinking milk or products containing milk.

According to Dr. Nguyen Thu Ha, there are a number of ways to help drink milk without causing stomach pain such as:

Use yogurt : The fermentation process of yogurt in the intestines will help lactose to be more easily absorbed, contributing to reducing the symptoms of lactose intolerance. On the other hand, the probiotics in yogurt are very good for the digestive system, increasing the ability to absorb nutrients. You should use yogurt every day to stimulate the digestive system to work more effectively.

Divide the amount of milk into small portions : If your body cannot immediately adapt to a large amount of milk, it is best to reduce the amount of milk you drink each time so that your body can gradually get used to it. In addition, you should drink milk after eating. This will help your body easily digest the nutrients in milk, avoiding diarrhea after drinking milk.

Do not drink milk with certain foods such as chocolate, tangerines, sugar, fruit juice. You should also drink milk at night, because milk contains tryptophan L, which makes the body more sleepy.
