<s>[INST] I had blood tests done last week and the results showed slightly elevated liver enzymes levels. I am wondering is this serious and what could the cause be. Is there any precautions I can take. I am 64 years. My GP has suggested I have same repeated in 2 months. [/INST] it may be serious condition. there are many causes of raised liver enzymes. most common of them are viral hepatitis like hepatitis b and c, fatty liver, alcoholism, autoimmune ds, drugs etc. you need to be worked in sequence for these various causes. it may turn out to be a simple disease as fatty liver or life threatening disease like cirrhosis or luver cance.so get evaluated by a Gastroenterologist as soon as possible.also workup will also be affected by level of these enzymes, i think basic test should be done before leaving as it is for 2 months in a old age patient. i would suggest go for basic test like viral marker,  usg etc uf no significant liver dysfunction noted can wait for 2 months and loose weight in the meantime if obese </s>
