<s>[INST] My son is 5 and half month old, having loose motion for last 7 days.. 7 to 8 times daily which is not usual for him. It s only water and no lumps in it. First it was yellow with mucous and later became green. Had stool exam .. Dr told lactose intolerance.. Started enterogerma yesterday ... Had fever before two days... Requesting opinion . [/INST] Lactose intolerance at 5 months of age could be due to an intestinal infection causing damage to mucosa and loss of Lactase enzyme function. Stool test will reveal Acidic pH. As for its management, put the child on lactose free diet for some time(avoid milk and milk products). Continue with Probiotics like Enterogermina, Give him Syrup Zincolife 2.5 ml once daily for 14 days. Also give a course of antibiotics in form of Syrup Oflox- Ornidazole complex. Give ORS solution so that he doesnt dehydrate and doesnt have electrlyte imbalance in the body. Once the acute condition subsides, reintroduce milk into the diet slowly. If he tolerates it, well and good. Otherwise keep him Off mil diet for a longer period. </s>
