Fish oil can do good things for your heart, but sometimes that help comes at the expense of your stomach. It's not uncommon for fish oil supplements to cause a number of gastrointestinal side effects that may lead to abdominal pain. However, since numerous conditions can cause stomach pain, don't assume fish oil is causing your problems. Instead, check with your doctor to find the source of the pain.
Omega-3 Fatty Acids
Fish oil is widely available in liquid or capsule form, and has grown in popularity as a supplement because of research into the many benefits of omega-3 fatty acids. Fish oil contains both docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). If you're buying fish oil, check the label to see how much DHA and EPA you'll be getting in each dose. Your doctor can recommend the right amount for you based on your health condition.
Fish Oil Benefits
If you have high triglyceride levels, your doctor might recommend taking fish oil supplements because the omega-3 fatty acids in the oil can help to bring your triglyceride levels into a healthier range. The DHA and EPA in fish oil also can help reduce other risk factors for heart attack, such as high blood pressure. For people who have experienced a heart attack, fish oil can help lower the risk of another attack. Scientists are also researching fish oil's benefits for people with medical conditions such as diabetes, rheumatoid arthritis, osteoporosis, depression and other mental health issues.
Fish Oil Side Effects
Unfortunately, one of fish oil's common side effects is gastrointestinal trouble. Some people experience gas, bloating and diarrhea, which can cause discomfort or pain. Others are bothered by a fishy aftertaste or fishy burps. In that case, swallowing frozen capsules or taking them with food may help. Some supplements are sold with an enteric coating that also can help with these milder side effects. In high doses, fish oil may cause excessive bleeding, so it's important to check with your doctor to make sure that it is safe for you.
Warning
If you're experiencing stomach pain, don't assume your fish oil capsules are to blame. MayoClinic.com notes that painful bloating may also be related to stress, smoking, a gastrointestinal infection, blockage or disease, irritable bowel syndrome, or conditions such as celiac disease or lactose intolerance. It's important to seek medical help if your pain is severe or if you experience nausea, vomiting, bloody stool, weight loss, fever, chest pain, diarrhea or constipation.
