Hello Thanks for writing to HCM Increased ALT indicates liver injury.Increase in ALT may be due to many reasons like hepatitis,alcohol intake,altered lipid profile,medicines,auto immune causes etc. You need few other investigations like routine hemogram,Random blood sugar(RBS),LFT,RFT,GGT,ultrasound of abdomen.Further investigations can be done if needed. You should avoid red meat and high fat milk products. Cook food in olive or canola oil. You should also avoid fried and junk food. Take lot of fruits and vegetables. TSH is also raised.Free T4 estimation should also be done. You may need thyroid hormone supplementation after clinical evaluation. Get well soon. Take Care Dr.Indu Bhushan
