Having colonoscopy next week. Is it critical that low dose aspirin, fish oil, multivitamin, and vitamin C be discontinued 7 days in advance?

Yes If Told Not: The Aspirin and fish oil both can thin your blood and cause bleeding issues during the procedures. Vitamins often have dyes in them that can discolor the tissues and make it difficult to accurately assess any conditions that might be present. Do you really want to go through the prep for the test to get false or inaccurate results? Follow the doctor's orders! ...Read more

Can taking fish oil cause LDL to be elevated? I'm taking it and i've never had a high LDL before.

Yes: Fish oils contain two active omega-3 fatty acids, dha and epa. Most fish oil products are a blend of these two fatty acids. Dha + epa frequently increases LDL cholesterol in a dose dependent manner (the higher the dose, the greater the increase). Recent studies show that purified epa (without dha) decreases LDL cholesterol with significant reduction seen at a 4 gram per day dosage. ...Read more

Unlikely: Red yeast rice is equivalent to 5mg of lovastatin. It could cause muscle aches and liver damage, but you won't notice this after only two days. Consult with your doctor regarding palpitations ; it would be reasonable to get bloodwork, and an ekg, as well as a holter monitor. ...Read more
