title: Clinical applications of fish oils.
abstract: Fish oil supplements are currently being nationally advertised, and many physicians are being queried about their clinical utility. Epidemiologic studies reveal a low incidence of cardiovascular disease in people, such as the Eskimos, who eat large amounts of seafood. Cardiovascular health may be improved because fish and fish oil supplements lower plasma lipid levels (especially triglycerides), inhibit platelet aggregation, and may decrease blood pressure and viscosity and increase high-density lipoprotein (HDL) levels. Preliminary observations also suggest a potential future role for fish oils in the treatment of some autoimmune diseases, such as atopic dermatitis, psoriasis, and rheumatoid arthritis. Patients with serum triglyceride levels greater than 5.64 mmol/L and/or cholesterol levels greater than 7.75 mmol/L refractory to dietary management may benefit from a medically supervised trial of fish oil supplements. Data currently available are insufficient to recommend fish oil supplements for the general public, or for patients with other diseases, and side effects must also be considered. These include occasional adverse lipid changes, potential for bleeding and vitamin E deficiency, and, with some preparations, vitamin A and D toxicity.
