Concerns over the potential risk of bleeding associated with this anti-platelet effect have led to recommendations that patients stop taking fish oil supplements before surgery and for delay in surgery if they are taking fish oil.
In a study published in the Journal of the American Medical Association (JAMA), researchers from the University of California, San Francisco (UCSF) School of Medicine, and the Mayo Clinic in Rochester, Minn., examined the effects of a single dose of omega-3 fatty acids (EPA and DHA) on platelet function in patients undergoing coronary artery bypass graft (CABG) surgery.
The study was funded by the National Heart, Lung and Blood Institute (NHLBI), National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), and National Center for Complementary and Alternative Medicine (CCAM) at the NIH.

How soon should you stop taking fish oil before surgery?
3 weeks prior to surgery, fish oil should be stopped. It is advisable to stop taking a daily dose of vitamins at least three weeks before surgery to reduce the risk of blood clots.
Does fish oil cause bleeding during surgery?
During and after surgery, fish oil exposure did not increase bleeding or blood transfusions. Fish oil supplements reduced the amount of platelets in healthy volunteers.
Is fish oil blood thinner?
Fish oil is a natural anticoagulant, which means it can prevent the blood from clotting. Thinning the blood may improve cardiovascular health, so this property may help explain some of the benefits. Omega-3s can increase the risk of bleeding when taken with certain drugs.
Omega-6 fatty acids are found in fish oil, but they are not as effective at preventing blood clots. They may also increase the risk of heart attack and stroke, especially in people with high blood pressure, high cholesterol, or diabetes.
What vitamins should I avoid before surgery?
These items should be avoided. Vitamin E, vitamin C, vitamin K, B vitamins, fish oils, and all herbal supplements should all be STOPPED 1 week pre-surgery.
Does fish oil slow wound healing?
Scientists Suspect Omega-3 Fatty Acids Could Slow Acute Wound Healing. A recent study shows that popular fish oil supplements have an effect on the healing of small wounds.
The study, published in the Journal of the American College of Cardiology, found that omega-6 fatty acids, which are found in fish oils, were more effective in reducing the rate of wound healing in a group of patients with acute, non-healing wounds compared to a control group that received a placebo. Fish Oil Supplements May Reduce the Risk of Heart Attack and Stroke in Patients With Type 2 Diabetes.
The risk of heart attack and stroke in people with type 2 diabetes has been linked to high blood pressure, high cholesterol, and high triglycerides. However, the mechanisms by which these risk factors contribute to the development of these diseases are not well understood. In the present study we investigated the effects of fish-oil supplements on blood lipids and lipoproteins in healthy, normocholesterolemic men and women aged 40 to 70 years.
Why do doctors ask if you take fish oil?
It’s important to get your triglyceride levels under control because research shows that high levels are linked to an increased risk of heart disease and stroke. If you have a history of high blood pressure or high cholesterol, you may want to avoid high-dose statin drugs. Statins are used to lower cholesterol levels, but they can also increase your risk for certain types of cancer, including breast, colon, prostate, and pancreatic cancer.
The most common side effect is weight gain.
Is it okay to take vitamin D before surgery?
Vitamin D3 (cholecalciferol) 50,000 IU by mouth daily for each of the five days prior to surgery. The pre-operative blood draw will check for the following: Resistin, Calcium, and Vitamin D. Pre-operatively, a blood sample will be taken from the patient’s arm to check for vitamin D deficiency.
The patient will also be asked to provide a urine sample to test for resistin, which is a protein found in the urine that can be used as a marker for the presence of resistance to antibiotics. If resistance is present, the sample should be sent to a laboratory for further testing to confirm the diagnosis.
If a patient is found to be deficient in any of these micronutrients, he or she will need to supplement with a daily dose of a vitamin or mineral supplement. This will help to ensure that the body is getting the nutrients it needs to function optimally.
Is it OK to take fish oil before a colonoscopy?
You should stop taking fish oil two days before your colonoscopy. Unless otherwise instructed by your health care provider, you can continue taking this after the test. If your test result is abnormal, you should see your doctor right away. Your doctor may order additional tests to rule out other conditions that may be causing the abnormal results.
Does fish oil affect blood clotting?
It’s possible that all fish oil capsules can cause trouble with clotting. prostaglandins are substances that affect the body’s ability to clot, both from the inside and the outside of the blood vessels, after ingestion of the fish oils.
This can lead to a condition called thrombocytopenia, in which the red blood cells are unable to carry oxygen to the tissues, causing a buildup of clots that can block blood flow to vital organs, such as the heart, lungs, and brain.
In severe cases, this can result in a heart attack, stroke, or even death. †‡† Fish oil supplements are not approved by the FDA for the treatment of heart disease.
