Arms Assigned Interventions
Experimental: NASH Drug: Metformin
Metformin is used.

Detailed Description:

In patients receiving bariatric surgery, a preoperative liver biopsy will confirm the presence of NASH. Those patients with NASH (histologically defined according the Brunt's criteria) will be randomized to receive metformin (2 times 850 mg orally daily) or placebo for a time period of 1 year. A control liver biopsy will be performed after one year.
