Every drug has its own advantages and disadvantages. A medicine should be taken only if prescribed or recommended by a qualified healthcare professional. Omega-3 fatty acids may reduce the risk of coronary heart disease but more research is needed. Few side effects can occur with omega-3 supplementation like hypotension, high blood sugar, allergies etc. Do not stop statins without consulting your doctor. It is suggested to consult your doctor for more queries and assistance. I hope it helps.
Best wishes and kind regards!
Omega 3 oils by themselves won't replace statins. Doing this the natural way would require a complete program, including diet, exercise, relaxation exercises, and supplements for reducing cholesterol, protecting the integrity of the blood vessel walls, etc. You would need expert help here, such as a naturopath or a practitioner of integrated medicine to determine whether your condition is even amenable to natural medicine without risk since we have no idea the seriousness of your stroke or how clogged your blood vessels are.
