Can Intake Of Iron Supplements Damage The Liver?

Dear Doctor, This is Diptiman Chakravorty age 32 male, obese individual height 5ft 7 in, weight 122 kgs. Two years back, I was diagnosed with fatty liver. Last month, I started feeling extremely weak and consulted a Dr. Blood tests revealed low Haemoglobin levels of 10.8. Last year it was 14. I was advised upper GI endoscopy, Colonscopy and stool for routine and occult blood tested. Upper GI endoscopy result:-Gastritis in antrum and healed duedonal ulcer. Colonoscopy report :Normal. and occult bleeding in stool negative. Dr prescribed Vivolib 500, Omez 500, Kinpride, Pibizyme, ursocol 300 and mild iron supplement Livogen(once daily at night). Within a week my hb levels went to 12.2 which Dr says is not bad.Other drugs described above are being used to treat gastritis and fatty liver. II have also been asked to loose weight. I am not diabetic and do not smoke or drink alcohol. My query is does gastritis cause such types of anemia, and how long should I continue to take Livogen (iron supplement)? Moreover, I am worried whether taking iron supplement will damage liver(fatty liver)further and am I in the taking the right medicnes for my condition? MY SGPT and SGOT are at normal levels at present..my present energy levels are low, yet I am walking 20 minutes daily.My doctor loosing weight gradually through exercise and diet modifications will help, but I am worried about anemia :-too much iron :-liver damage, too less anemia. How do I strike a balance. Please advise accordingly. I am still young and keep worrying constantly due to my helath conditions.
