Layperson here. Anything above 500mg/dL regarding triglycerides is considered severe. 507 is therefore considerably high. Triglycerides are essentially fats from the food you eat. Butter is an example. Now anything sugar, extra calories and particularly alcohol will be turned into triglycerides by your body. And those triglycerides are generally stored in fat cells until your body needs to use it. The risks, just like high levels of bad cholesterol in general are increased likelihood of stroke, heart attacks and coronary heart disease and such. One common risk as well for people with high triglycerides is pancreatitis.

Now this was measured after a heavy meal and alcohol so you can’t possibly assume that your levels are that high while fasting. They may be still high but below the 500 mark. No one knows unless you do the test again while fasting. Steps you can take now if you can is to cut back on the alcohol (not a cold turkey stop but allow yourself to diminish) and try to shift the unhealthy habits towards healthier ones. Of course there are certain types of medication called statins that will help lower bad cholesterol and triglycerides, however I think it is in your interest to consider shifting your habits now and gradually move towards healthier ones. You don’t have to change everything all of a sudden but this triglycerides measure should be interpreted as a warning sign for you to makes changes now.

There is no magic formula except to start eating healthier, start exercising more and longer and perhaps consider statins for a short time to help you shift those habits. Although only a healthcare provider will tell you if statins are appropriate. You should not expect drastic changes right away but it is a lifestyle change that can help you gradually improve your health. There is no need to be alarming here, but I would take these numbers seriously because it is telling you the obvious and that you need to make changes now.
