Babies with megacolon will have dry, dark stools, and a large amount of stool after passing. If the baby is born with megacolon, he or she may have symptoms of constipation, and the baby may not have a bowel movement for several days or the stool discharged is dry and hard, and the color of the stool is dark. If the baby rarely defecates by himself, he can stimulate the anal area by means of unguents or soap bars to promote the discharge of stool, and the amount of stool discharged in this case will be larger. In addition, within two days of birth, if there is no stool discharge or a small amount of stool is discharged, within two or three days of low-level partial or complete intestinal obstruction, the baby will also show some manifestations such as vomiting, abdominal distension, and no bowel movement. Therefore, you can go to the hospital for examination, and only after rectal rectal examination or warm saline enema, a large amount of stool and gas can be discharged and the baby’s symptoms can be relieved.
