Can probiotics improve constipation in babies?

Can.
Dysbiosis of the intestinal flora can reduce the peristaltic function of the intestine, raising the pH of the intestine and disrupting intestinal function eventually leading to constipation.
Bifidobacterium bifidum is a micro-ecological agent that lowers the pH of the intestine, promotes intestinal motility and speeds up the elimination of faeces, thus improving the symptoms of constipation in infants.
