Many people do not know that they are suffering from lactose intolerance. Lactose is found in many products: milk, cheese, yogurt, but also in chocolate and many other products. However, many people do not know that they are suffering from lactose intolerance.

Symptoms are not as strong as in allergies, so people continue to consume milk and dairy products, and the body suffers. If you suspect, here are the damaging symptoms that are indicators of lactose intolerance …


One of the typical symptoms of lactose intolerance is bloating. Collecting carbon dioxide and methane in the gut and causing great bloating.

Pain in the stomach

If you suffer from gases and bloating, it’s normal that you can not let them go at any moment. However, it has its consequences: when you keep the gases, the intestines are tense and cause pain and strange sounds.

Cramps in the stomach

One of the symptoms of lactose intolerance is definitely stomach cramps.


Another symptom of lactose intolerance is diarrhea. The body is not capable of dividing lactose into the small intestine, so it all happens in the colon. In addition, lactic acid, due to which water is accumulated in the digestive tract and diarrhea occurs, among other things.


It may sound contradictory, but with time, lactose intolerance also causes constipation. This can happen when methane is caused by intolerance in the intestine. The intestines work slower due to gases and come up with unpleasant constipation.

Nausea and vomiting

Due to the inability of the body to break down the lactose, the digestive system is extremely overburdened and it comes to nausea, and in severe cases, to vomiting.

Headache and Dizziness

Untypical symptoms of lactose intolerance are headache and dizziness. It is not entirely clear why these symptoms occur, but it is possible because of the lactose in the colon to produce substances that reach through the blood through the whole body and thus cause problems.
