Hi, Recently My Brother Aged 37, Had COLONOSCOPY Done, And

Hi, Recently my brother aged 37, had COLONOSCOPY done, and during the blood test, we found that his haemoglobin content is 17.7 (more than normal) and the Ultrasound report showed that the LIVER contained fats (more than normal). The Doctor suggested us to get the opinion of an Hematologist.
What's the problem high haemoglobin + fats in Liver suggest.
