<s>[INST] Hi, even though my 6 year old daughter does not have symptoms of a low grade fever, she has however keep constant stomach aches and fatigue. Now she is showing brown circles under her eyes (like a very sick child) vs. black circles (tired, allergy, etc..looking). At one point her ped. recommended a CT scan, which revealed backed up bowels. We started using Miralax. Well, her symptoms have not improved and we do have a follow up coming up next week. I am trying to find answers, information, etc... because I have noticed that this is affecting her in school and in our daily lives. Please advise...Thank you... J [/INST] fatigue and abdominal pain which was worrisome that she needed a CT scan is not consistent with constipation unless the child passes motion every couple of weeks , so miralax will not help if she doesn't have sever constipation .this abdominal pain which shifts the child away from school isn't consistent with functional abdominal pain either so it's must be investigated carefully .I recommend the following blood tests : -complete blood count and blood film -fasting blood sugar -urea and creatinine -thyroid function test - celiac screen : anti-TTG IGA and total serum IgA -urine culture. these tests are to role out malignancy , diabetes , chronic kidney disease, hypothyroidism , celiac disease and urinary tract infection which all can cause abdominal pain and fatigue .I hope this helps </s>
