The baby started with a cold, running nose, and hoarse voice six and a half months ago. The next day, they had diarrhea. Now that the cold has cleared up, the baby has been having diarrhea for over a week. Yesterday, it seemed better, so the medication was reduced, but this morning they had diarrhea with foam and mucus and even blood threads. If your baby has diarrhea, consider the possibility of gastroenteritis or gastroenteric cold. It could also be due to catching a cold or dyspepsia caused by intestinal flora imbalance. It is recommended that you visit a regular pediatric department hospital promptly for examination. Conduct routine checks to determine if there is inflammation in the child’s stool. After an accurate diagnosis, follow the doctor’s treatment advice and medication and treatment plan.
