If you're thinking about taking fish oil supplements, you need to weigh the risks and benefits. Many doctors recommend fish oil to lower triglycerides and the risk of heart problems. Some people use fish oil to treat a host of other health issues, too, such as depression, dry eyes, diabetes and asthma. But the supplements can cause problems, such as diarrhea and other gastrointestinal ills. Talk with your doctor about the advisability of taking fish-oil supplements or eating more fish.
Fish-Oil Benefits
Fish oil is a popular supplement, because it contains omega-3 fatty acids, which play a role in brain function and growth and development. In addition, omega-3 fatty acids may reduce the risk of heart disease. Because your body cannot make these essential fatty acids, you need to get them from food or supplements. The American Heart Association recommends eating fish at least twice a week to get omega-3 fatty acids in your diet, but some people turn to fish oil supplements to make sure they're getting enough.
Diarrhea
One of the known side effects of taking fish oil supplements is diarrhea. While it is usually just an unpleasant condition, any time diarrhea persists for more than three days you should see your doctor. Dehydration can be a serious result of diarrhea. Fish oil can cause other gastrointestinal problems, too. Some of the common complaints are burping, indigestion, abdominal bloating and abdominal pain. You also might get a fishy aftertaste from the supplements.
Reduce Risk
You can lower your risk of diarrhea and gastrointestinal upset. First, check with your doctor to make sure fish oil is right for you. If it is, start with small doses, and gradually increase the dosage over time. If you take fish-oil capsules, try storing them in the freezer to minimize burping and the fishy aftertaste. Freezing slows the breakdown of the capsules in your stomach. Take your fish oil with meals to further minimize digestion problems.
Warning
In addition to gastrointestinal problems, fish oil may increase the risk of bleeding. High doses may increase your risk of stroke, nosebleeds and blood in the urine. Health officials recommend limiting your intake to no more than 3 g a day, unless you are under the supervision of a doctor. The supplements also can interact with some medications, including blood-pressure drugs and blood thinners, such as warfarin.
Choose your supplements carefully to reduce risk of mercury contamination. Look for USP verified on the label, which means the product meets standards for purity and potency set by the U.S. Pharmacopeia.
