Does alcohol raise triglycerides?
On this page
Yes. In 42 studies, about 2 drinks a day raised triglycerides by about 6 mg/dL on average, with a range of 2.5 to 9. Some people react far more. At fasting triglycerides of 500 or more, the 2026 US guideline says no alcohol at all.
What we’d do
If your triglycerides are high, alcohol is the first thing we’d cut. It’s the change you control completely, and a retest 4 weeks later will show you what it did. Ignore the idea that a drink a day is good for your cholesterol because it raises HDL. If you drink heavily every day, talk to a doctor before you stop, because sudden withdrawal can be dangerous.
Why people miss it
Alcohol doesn’t look like fat or sugar, so it rarely makes the list when someone wonders why their triglycerides are high. And the same drinks raise HDL, which gets alcohol a reputation as heart-friendly. The guideline lists alcohol excess among the common causes of high triglycerides.
What the studies found
In 1999, researchers pooled 42 studies where healthy adults, none dependent on alcohol, drank a set amount every day for 1 to 9 weeks. At 30 g of alcohol a day, a little over 2 US drinks:
| Number | Change |
|---|---|
| Triglycerides | up 5.7 mg/dL (2.5 to 8.9) |
| HDL | up 4.0 mg/dL (3.3 to 4.7) |
A US standard drink holds about 14 g of alcohol: 12 oz of regular beer at about 5%, 5 oz of wine at about 12%, or 1.5 oz of spirits at about 40%.
That’s an average for healthy people at a moderate dose. The guideline lists heavy drinking among the main causes of high triglycerides.
The HDL trap
The same 1999 paper estimated that these changes in the blood, the HDL rise among them, could mean about a quarter less heart disease. Raising HDL with a drug hasn’t held up. In the AIM-HIGH trial, 3,414 people with heart disease on a statin took niacin or a placebo. Niacin raised HDL from 35 to 42 and lowered triglycerides from 164 to 122, and after 3 years the two groups had the same rate of heart attacks, strokes and deaths (16.4% against 16.2%). A higher HDL from drinking makes your panel look better, and nothing has shown that it helps your arteries. See how do I raise my HDL? for what to do instead.
What the guideline says, by level
| Fasting triglycerides | Alcohol |
|---|---|
| 150 to 499 mg/dL (1.7 to 5.6 mmol/L) | keep it to a minimum, along with added sugar, refined carbs and saturated fat |
| 500 to 999 (5.7 to 11.3) | none |
| 1000 or more (11.3) | none, with a very low fat diet and no added sugar, planned with a dietitian |
Triglycerides track your drinking like a phone bill tracks your calls. Fewer drinks this month shows up on next month’s panel. The four week plan starts with the drinks.
For heavy drinkers
MedlinePlus warns that alcohol withdrawal can “quickly become life-threatening.” If you drink heavily every day, plan the cut with a doctor. Alcohol also raises blood pressure and lowers HRV, which bloodpressure.guide and hrv.guide cover.
