You can tell how lactose intolerant you are by the symptoms that can occur with lactose intolerance.

Look to see if you can finish your milk at each meal

Lactose intolerance can be judged by life experience. If you can't finish your milk every time, this could be a sign of lactose intolerance. We can also test the concentration of galactose in the urine after drinking milk by testing the urine, which is the most common way to test for lactose tolerance, with reliable and inexpensive results. It is also possible to determine this by testing DNA, because if DNA fragments associated with lactose tolerance are detected in the body, this method is reliable but slightly more expensive.

Whether you get headaches

If you get headaches caused by abnormal metabolism after eating some lactose-based foods, this is a good time to be aware that you may be lactose intolerant. In addition, because the water in the body's colon will increase, so that the volume of feces and the content of liquid in the rapid expansion, which can cause diarrhea symptoms. If your have diarrhea occurs and at the same time you eat some lactose foods, then it may be lactose intolerance.

Other Symptoms

If your body is unable to absorb and digest whey protein, it may cause bloating, which is caused by bacterial lysis in the abdomen. Skin eczema is a common condition that can be easily seen, but few people realize that when lactose intolerance occurs, skin eczema may also occur. So if you have such a condition, all aspects should be taken into consideration. Finally, people with lactose intolerance can also experience severe constipation. However, it is important to emphasize that diarrhea and constipation are not contradictory. Since half of the whey protein is digested and absorbed in the body, bacterial dissolution occurs when it enters the stomach, and this is converted to methane gas, which restricts intestinal peristalsis in the gut and then severe constipation occurs. If the above situation occurs, then the probability is lactose intolerance. Usually in terms of diet, you need to pay more attention to the issue of dietary matching.
