High triglycerides? Here's what you can do about it

When you get your blood work, be sure to consider not only the "good" (HDL) and "bad" (LDL) cholesterol readings; also ask your doctor to assess whether that third thing the test measures -- triglycerides -- is within a healthy range.

Most of the sources I read say that a level at or above 200 is cause for concern.
This is a measure of fatty substances in your blood, and too high a reading can lead to significant health problems, including heart disease or stroke.
Here's advice (from Web MD) about ways to bring down your triglyceride reading.

• Moderate exercise on five or more days each week can help lower triglyceride levels.
• Losing 5%-10% of your weight can lower triglycerides. People with a healthy weight are more likely to have normal triglyceride levels. Belly fat is associated with higher levels.
• Reducing saturated fat, trans fat, and cholesterol in your diet can improve triglyceride levels and help manage cholesterol. Eating less carbohydrates in your diet will also help lower triglyceride levels.
• Drinking alcohol can raise triglyceride levels. Some studies show that drinking more than one drink a day for women or two for men can raise triglyceride levels by a lot. Some people with high triglycerides may need to cut out alcohol entirely.
• Eating more fish high in omega-3s can lower triglyceride levels. Fish like mackerel, lake trout, herring, sardines, albacore tuna, and salmon are high in omega-3s. It may be hard to get enough omega-3s from food to help lower your triglycerides. Your doctor may recommend a supplement or prescription omega-3s.

If these steps don't provide enough relief, you may have to go on medication. This is something you'll have to take up with your physician.
Because I drink alcohol, I tend to have elevated triglycerides. That along with other considerations does cause me to cut back on drinking -- from time to time, at least.
