When adults have problems such as constipation, diarrhea and food accumulation, they will mostly take probiotic preparations to improve the gastrointestinal environment, promote the improvement of the disease and restore the gastrointestinal health. However, it is absolutely wrong to use this way to treat pre-six-year-olds, expecting them to take probiotic preparations to strengthen their gastrointestinal resistance. In addition, the author believes that it is best not to give probiotics to pre-six-year-olds. First of all, it is certain that if synthetic probiotic products are taken for a long time, the intestinal tract will gradually lose its ability to reproduce beneficial bacteria, thus making the body dependent. This is known as “”probiotic dependence”” in medical science. If you suffer from this disease, you will have to rely on this oral probiotic product to maintain your health for the rest of your life. Babies before the age of six are the most likely to suffer from this helpless disease. In addition, if probiotics are overused, they can also breed new hotbeds of superbugs in the body. This is mainly because many lactic acid bacteria have multiple resistance to antibiotics, through the common life and contact with the pathogenic bacteria, it is likely to carry their own resistance genes to the pathogenic bacteria, so that they get resistance and become “super germs”, resulting in infection can not be cured. Of course, it is not completely impossible to supplement probiotics for babies. In the following two cases, it is possible to supplement in moderation. 1, the baby if long-term use of antibiotics, then you need to supplement probiotics. Because antibiotics will not only kill the pathogenic bacteria, but also kill the probiotics that coexist with them. 2, when the baby has diarrhea, the baby’s intestines will lose a large number of probiotics, thus causing various diseases, resulting in an imbalance of intestinal bacteria, you can also follow the doctor’s advice, appropriate supplementation of probiotics.
