At the same time, it will be decomposed into lactic acid and acetic acid by bacteria, which will reduce the pH value of the intestine and stimulate intestinal peristalsis. Moreover, the increase of acidic components in the intestine will further increase the osmotic pressure in the colon and retain more water in the intestine, thus making the stool soft and having a cathartic effect. In addition, lactulose can also promote the proliferation of Bifidobacterium, increase the number of probiotics in the intestine, inhibit the growth of harmful bacteria such as Escherichia coli, and be beneficial to the recovery of intestinal function.
Therefore, although lactulose is an artificial disaccharide, functionally speaking, it is actually a hypertonic laxative, which belongs to what we often call a "laxative". If the baby is seriously constipated, you can give it to the baby. It will hardly cause systemic toxic and side effects and will not harm liver and kidney, so it is safe. But be careful not to eat it for a long time to avoid dependence. If it really needs to be used for a long time, it is up to the doctor to judge.
Finally, the baby's constipation is mostly due to the lack of cellulose and intestinal contents (that is, food residues and feces), which leads to slow intestinal peristalsis, so that feces are continuously absorbed in the intestine and eventually become dry and difficult to discharge. Therefore, in order to avoid constipation, it is necessary to increase intestinal peristalsis and increase the moisture of feces. Usually encourage children to exercise more, drink more water and eat more fruits and vegetables, and constipation will be relieved a lot.
