The reason why you fart after drinking milk

Milk is a type of milk with relatively high nutritional value, and with the continuous improvement of economic conditions, many people drink milk every day. However, some people fart frequently after drinking milk, which makes them feel very embarrassed. Therefore, they want to fully understand the reasons why people fart after drinking milk. The following is a detailed introduction so that you can have a comprehensive understanding.

Lactose intolerance refers to the body's inability to break down and metabolize lactose (a sugar found in milk and other dairy products). This is caused by a lack of the required lactase in the intestines or a decrease in the activity of the lactase. It is estimated that approximately 75% of adults worldwide have reduced lactase activity. The incidence of this symptom is about 5% in Northern Europe, but exceeds 90% in some Asian and African countries.

Simply put, lactose intolerance is a condition caused by a lack of lactase or insufficient activity of the enzyme used to digest lactose. This condition is common in Asia and Africa.

Overview

Disaccharides (lactose belongs to disaccharides) cannot be directly absorbed by the intestinal mucosa and enter the blood circulation. Therefore, in the absence of lactase, the lactose in dairy products directly enters the colon without being broken down. At this time, operons of enteric bacteria in the intestine will convert into lactose metabolism, ferment in the body and produce a large amount of gas (this gas is a mixture of hydrogen, carbon dioxide and methane). This process may cause abdominal symptoms, including stomach cramps, bloating, and gas. In addition, like other unabsorbed sugars (such as sorbitol, mannitol, and xylitol), lactose and its fermentation products can cause the contents of the large intestine to form a state of hyperosmotic pressure.

Classification

There are three main types of lactose intolerance:

1. Primary lactose intolerance: It can be caused by environmental factors, such as weaning a child in an environment without dairy products. This often happens in Asian and African countries where an industrialized, market-oriented dairy industry has not yet been established.

2. Secondary lactose intolerance: It can be caused by environmental factors; or by specific gastrointestinal diseases, including intestinal parasites (such as Giardia), in which case the function of producing lactase will be permanently destroyed. Gastroenteritis is a common cause of temporary lactose intolerance, especially when rotavirus (a virus that causes gastroenteritis in infants and newborns) is the causative agent. If infants consume too much lactose, it can also lead to temporary lactose intolerance.

3. Congenital lactase deficiency: This is a functional failure of lactase production caused by genetic dysfunction. This congenital condition can be diagnosed shortly after birth.

The above is a comprehensive introduction to the reasons why drinking milk causes farting. After fully understanding the above content, I believe you will have a full understanding of the reasons why drinking milk causes farting. After understanding the reasons, it can be recommended to replace it with other milk or other foods, and farting will no longer occur.
