Study Finds Omega-3s Do Not Increase Bleeding During Surgery

There has been some debate in the past about whether fish oil supplementation may lead to longer bleed times, leading some health professionals to suggest that patients stop supplementation before surgery. However, a recent study suggests that there is no association between fish oil supplementation and the risk of bleeding.


Researchers from Aarhus University Hospital, Denmark examined data from 52 studies, 32 of which included healthy participants and 20 including people who were undergoing surgery. After examining the data, they that supplementation was associated with reduced platelet aggregation in healthy subjects.


However, they also determined that there was no association between fish oil supplementation and increased bleeding or the need for blood transfusion during surgery. As a result, they determined that there is no need to discontinue fish oil supplementation prior to surgery.


The study was published in the May 2017 issue of Danish Medical Journal.


Fish oil’s health benefits are due to its high levels of omega-3s. Omega-3s have been linked to a number of health benefits, including improved mood, improved joint mobility, reducing the risk of age related macular degeneration, and aiding your immune system.


Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. For vegans like the ones in this study or for folks who just don’t like fish, consider taking a daily high quality non-fish supplement that has been tested for purity and potency.
