50 days baby does not poop only fart, common in constipation, may be indigestion, intestinal flora imbalance and other reasons, can be improved through the bowel habits, the application of drugs and other ways to promote defecation. 1. Indigestion: Indigestion leads to slower gastrointestinal peristalsis, which increases the amount of feces retained in the intestines for a long period of time, resulting in farting all the time without pooping. You can give compound pepsin to help digestion, bacillus subtilis bacillus granules to regulate intestinal flora, and you can also rub the baby’s abdomen to increase gastrointestinal peristalsis and promote defecation. 2. Intestinal flora imbalance: Harmful bacteria in the intestines multiply more, resulting in no poop and fart. Probiotics, such as Saccharomyces boulardii and Bacillus subtilis granules, can be given to regulate the intestinal environment and promote defecation. If your 50-day-old baby is not pooping but farting, we suggest that you consult a doctor to find out the cause of the problem and take active treatment. The above medications should be used according to medical advice.
