She has lost 21 pounds she is in constant pain she was seen by GI this past friday and they have set her up for colonoscopy and EGD.  The pain increases after she eats and after she has a bowel movement and her bowel movements have had mucous in them.  What could this be please help???? [/INST] Hi. Thanks for your elucidate history. Young child of 10 years loosing so much weight and have Mesenteric Lymphadenitis and symptoms of bowel movements with mucus and has to go after food is suggestive of Tuberculosis of the abdomen / or a Cancer like lymphoma.IT is good that she will be subjected to Colonoscopy that biopsy can be taken if a lesion is seen in the colon. EGD for secondary changes. The best diagnostic tools in such a case are :Blood-complete blood picture, kidney functions tests, blood sugar fasting and post-lunch, Urine-routine, microscopy, culture and sensitivity (before start of antibiotic)Diagnostic Laparoscopy with FNAC or preferably biopsy of the lymph nodes will give a definite diagnosis. So that a proper treatment can be started ASAP </s>
