Can regular use of fish oil cause blood sugar levels to increase?
A. There is conflicting information regarding fish oil’s affect on blood glucose levels. In most cases, fish oil has not been shown to have a long term adverse effect on blood glucose levels. However, there have been a few studies that have shown worsening blood glucose control in patients taking high doses of fish oil. Monitor your blood glucose levels while taking the fish oil and report any changes to your physician to determine an appropriate treatment plan.
