<s>[INST] I have a high gamma gt level but all other bloods are perfect, I don't drink alcohol and a few years back also my gamma gt was high. Last 8 years I have been using Seretide evohaler for the asthma. can this be a major reason for high gamma gt (95 U/L) [/INST] Hello.Initially,use of mentioned inhaler is not related with increased levels of GGT. Besides alcohol, excessive consumption of fatty foods and  overweight-obesity are common causes of increased levels of GGT.Your doctor should assess about the most likely cause of increased GGT in your situation.I wish you good health.(If the answer has helped you, please indicate this) </s>
