Patient: My baby is now eight months old, from six months onwards, the stool began to be abnormal, the shortest once every four or five days, the longest once every six or seven days, the child’s stool began to be particularly dry and hard, egg-shaped part, and then the part of the stool came out softer, the last half of the month defecation only slightly soft into a pout, the color of the big change is normal, the child also did not appear bloating, abdominal pain, but the child has been crying when the stool, very painful. Also, my baby breastfeeding, six months ago has been diarrhea, had taken 3 times Smita, when I also took 10 consecutive days Smita, found that the child then began to constipation, has lasted for more than two months, all kinds of methods have been used, drinking water, juice, vegetable juice, etc., are not effective, read the information on the Internet, do not know if it is a giant colon? How can I do a barium permeation for my child? Will it be very painful? Doctor: From the situation you described, six months after birth began to appear abnormal bowel movements, mainly prolonged intervals between bowel movements, no abdominal distension, vomiting? There is no bloating or vomiting. The possibility of having megacolon is unlikely, but of course the possibility of megacolon homologation cannot be completely ruled out. It is recommended that: 1. add complementary food feeding and increase the amount of vegetables; 2. if the third day does not defecate, consider the application of corked aid; 3. appropriate application of some intestinal bacteria drugs, such as gold bifid; 4. after 2 to 3 months of active treatment without significant effect, come to the hospital to perform anal and rectal manometry and barium enema angiography, some children may need to take pathological sections for diagnosis.
