Hi thanks for contacting HCM... Here your GGT level slightly elevated... This enzyme present in bile canaliculi ..So whenever damage to this this enzymes elevated in blood.... So you could have cholangitis like infective condition .... For that USG abdomen done for hepatobiliary system workout.... Second your diarrhea and fever could be by gastroenteritis infection .... So you can take suitable antibiotic treatment for five days .. Symptomatic management done with more fruits ... Avoid smoking and alcohol ... Fatty and fried food less.... Junk foods restricted.... Some good foods for liver can be taken like carrot/ spinach / Indian goosebery / lomon juice etc... Maintain hydration for diarrhea... For vomiting metoclopramide or domperidone can be taken... If after few days still GGT elevated consult gastroenterologist for that... Take care
