Names & Terms You Will Hear
Plain-language meanings for the terms your care team may use.
| Term | Meaning |
|---|---|
| Triglycerides (TG) | Blood fats made from the calories your body does not use right away. Measured as part of a standard lipid panel. |
| VLDL | Very-low-density lipoprotein — the particle that carries triglycerides through the bloodstream. High VLDL raises heart risk. |
| Hypertriglyceridemia | The medical term for high triglycerides — any level at or above 150 mg/dL. |
| Remnant Cholesterol | Cholesterol left inside TG-rich particles after they release their fat. Drives plaque even when LDL looks normal. |
| Non-HDL Cholesterol | Total cholesterol minus HDL. Captures LDL plus all TG-rich remnants. Target is your LDL target plus 30 mg/dL. |
| Icosapent Ethyl (Vascepa) | A purified EPA omega-3 fish-oil prescription. Proven in REDUCE-IT to cut heart events — NOT the same as OTC fish oil. |
| Fibrate (Fenofibrate) | A medicine that activates the body's fat-burning enzyme (LPL). Lowers TG by 30 to 50 percent. Used mainly to prevent pancreatitis. |
| FCS (Familial Chylomicronemia Syndrome) | A rare genetic condition in which TG can exceed 1,000 mg/dL. Extremely high pancreatitis risk. Requires specialist care. |
| Familial Hypertriglyceridemia | An inherited tendency toward high TG (usually 200–500 mg/dL). More common than FCS. Responds well to lifestyle and medicines. |
| Pancreatitis | Sudden, severe inflammation of the pancreas. TG over 500 — especially over 1,000 — can trigger it. A medical emergency. |
1. Triglycerides — target < 150 mg/dL. Above 500 = urgent; above 1,000 = emergency.
2. Non-HDL cholesterol = Total minus HDL. Captures TG-remnant risk. Target = LDL target + 30.
3. HDL — target 40 or higher (men), 50 or higher (women). Low HDL + high TG = the metabolic syndrome pattern.
What Is Triglycerides?
- Triglycerides are the most common fat in your body. After you eat, your body converts extra calories into triglycerides and stores them in fat cells.
- Your liver also makes triglycerides — mainly when you eat a lot of sugar, refined carbs, or alcohol. The liver packs these fats into VLDL particles and sends them into the blood.
- A lipid panel checks four numbers: total cholesterol, LDL, HDL, and triglycerides. All four matter. Triglycerides do not get a pass just because your LDL looks good.
- Normal triglycerides are below 150 mg/dL. Borderline is 150 to 199. High is 200 to 499. Very high is 500 or above. Above 500 raises the risk of acute pancreatitis. Above 1,000 is a near-emergency.
- Triglycerides ride on VLDL in the blood. When VLDL drops off its fat, it leaves a remnant packed with cholesterol. Those remnants build plaque in artery walls — even when LDL is normal.
- Most people with high triglycerides feel fine. There are no symptoms at lower levels. Pancreatitis causes severe upper-belly pain that goes to the back. Seek care right away if this happens.
- Fasting gives the most accurate triglyceride reading. If your non-fasting TG comes back above 175, your team may repeat the test after a 9 to 12 hour fast.
Triglyceride categories — what each level means and what to do
| Level (mg/dL) | Category | What it means | Action |
|---|---|---|---|
| < 150 | Normal | Low risk from TG alone | Maintain with lifestyle; recheck every 4-6 years |
| 150–199 | Borderline High | Mild residual ASCVD risk; often lifestyle-driven | Diet and lifestyle intervention; address secondary causes |
| 200–499 | High | Elevated ASCVD risk via remnant cholesterol; may compound diabetes / metabolic syndrome risk | Lifestyle + treat secondary causes; consider statin; Vascepa if high ASCVD risk on statin |
| 500 or higher | Very High | Significant pancreatitis risk; also high ASCVD risk | Urgent: stop alcohol, cut fat drastically; fibrate or Rx omega-3 to prevent pancreatitis |
| 1,000 or higher | Severe (FCS / extreme) | Imminent pancreatitis risk; possible eruptive xanthomas | Specialist referral; may require IV insulin or plasmapheresis in acute pancreatitis setting |
Why It Matters
- High triglycerides raise heart risk two ways. First: VLDL remnant particles carry cholesterol into artery walls, even when LDL looks normal. Second: very high TG can inflame the pancreas — a medical emergency.
- Non-HDL cholesterol (total minus HDL) captures LDL plus all the TG-rich remnants in one number. It predicts heart risk as well as LDL alone. Your non-HDL target is your LDL target plus 30 mg/dL.
- REDUCE-IT (2019) found that icosapent ethyl (Vascepa) 4 g/day in statin patients with TG 135 to 499 mg/dL cut major heart events by 25 percent. The benefit went beyond TG reduction alone.
- High triglycerides often signal insulin resistance — the same process that leads to type 2 diabetes. Lifestyle changes and better blood sugar control bring TG down too.
- High TG plus low HDL plus small dense LDL is called metabolic syndrome or atherogenic dyslipidemia. It is one of the highest-risk lipid patterns for heart attack and stroke.
- Pancreatitis from very high TG hits fast. TG can spike after one high-fat meal or a night of heavy drinking. Know your number — prevention is far easier than treatment.
Risk Factors
Knowing your personal risks helps your care team take extra precautions.
| Risk Factor | Why It Increases Risk |
|---|---|
| Diet high in sugar, refined carbs, and alcohol | Excess carbohydrates and alcohol drive the liver to overproduce VLDL. Cutting these is the fastest way to lower TG without medicine. |
| Overweight or obesity | Excess body fat — especially around the belly — raises TG and lowers HDL. Losing even 5 to 10 percent of body weight can drop TG by 20 to 30 percent. |
| Type 2 diabetes and insulin resistance | Insulin resistance impairs the enzyme that clears TG from blood (lipoprotein lipase). High blood sugar also drives the liver to make more TG. Controlling glucose is part of the treatment. |
| Hypothyroidism (underactive thyroid) | Low thyroid slows TG clearance. A simple TSH blood test finds it; treating the thyroid often normalizes TG. |
| Chronic kidney disease | Impaired kidney function reduces TG clearance and can raise VLDL production. TG often improve if kidney disease is treated. |
| Medicines that raise TG | Corticosteroids, estrogen-containing pills, some beta-blockers, thiazide diuretics (at high doses), retinoids, and some antipsychotics can raise TG. Ask your doctor to review your full medicine list. |
| Genetic causes | Familial hypertriglyceridemia runs in families and causes moderate-to-high TG. Familial chylomicronemia syndrome (FCS) is rarer and causes extremely high TG — often over 1,000 mg/dL — with repeated pancreatitis. |
| Sedentary lifestyle | Physical activity activates the enzyme that clears TG from blood. 150 minutes per week of moderate exercise can lower TG by 10 to 20 percent. |
Lifestyle: The First and Best Step
- No medicine lowers TG as broadly and safely as lifestyle change. Diet and exercise help TG, blood sugar, blood pressure, and weight — all at once.
- The most powerful dietary move: cut added sugar and refined carbs. Swap white bread for whole grain and drop sugary drinks. This alone can drop TG 20 to 25 percent in 4 to 8 weeks.
- Alcohol is a direct TG driver. If TG is above 200, limit to fewer than 7 drinks per week. Above 500, stop completely until TG comes down.
- Omega-3 rich foods — salmon, mackerel, sardines, herring, flaxseeds — lower TG about 5 to 10 percent. They are NOT a substitute for Vascepa if you are a REDUCE-IT candidate.
- Walking 30 minutes a day, 5 days a week, lowers TG on its own. A 10-minute walk after the biggest meal blunts the post-meal TG spike.
- Losing 5 to 10 percent of body weight drops TG by 20 to 30 percent and raises HDL. Even 10 pounds makes a real difference.

Treatment Options
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
- Step 1 — Cut added sugar and refined carbs. White bread, white rice, sugary drinks, candy, and pastries raise TG fast. Swap them for whole grains, vegetables, and beans. This single change can drop TG 20 to 30 percent.
- Step 2 — Limit or stop alcohol. Even moderate drinking raises TG in some people. Stopping can drop TG 20 percent or more within weeks. If TG are above 500, stop completely.
- Step 3 — Lose weight if needed. Losing 5 to 10 percent of body weight drops TG 20 to 30 percent. Any eating plan that cuts calories works. See go.riasalimd.com/heart-healthy-eating-guide.
- Step 4 — Exercise regularly. 150 minutes per week of brisk walking or cycling turns on the enzyme that clears TG from blood. Lowers TG about 10 percent and helps insulin sensitivity.
- Step 5 — Treat secondary causes. Control blood sugar (see Diabetes & the Heart). Treat low thyroid. Review any medicines that raise TG.
- Step 6 — Add a statin if ASCVD risk warrants it. Statins lower TG 10 to 20 percent as a side benefit. The main reason: they cut heart attack and stroke risk. See go.riasalimd.com/statins-guide.
- Step 7 — Icosapent ethyl (Vascepa) 4 g/day if TG stay 135 to 499 on a statin and your heart risk is high. REDUCE-IT showed a 25 percent cut in major heart events. This is purified EPA — NOT the same as OTC fish oil. Prescription only.
- Step 8 — Prescription omega-3 (Lovaza) for very high TG (over 500) to lower pancreatitis risk. Lowers TG 25 to 30 percent. It contains mixed EPA + DHA — not like Vascepa. Not proven to cut heart events in major trials.
- Step 9 — Fenofibrate mainly to prevent pancreatitis when TG exceed 500 and lifestyle is not enough. Lowers TG 30 to 45 percent. ACCORD-Lipid showed a possible benefit in diabetes + high TG + low HDL, but PROMINENT (2022) was neutral on heart events. Use fenofibrate for pancreatitis prevention, not heart protection.
- Niacin (nicotinic acid) lowers TG but is rarely used now. Large trials (AIM-HIGH, HPS2-THRIVE) showed no heart benefit added to a statin. It causes flushing, high blood sugar, and liver stress.
OTC omega-3 capsules (fish oil) contain a mix of EPA + DHA and have not been proven to reduce heart events. Vascepa (icosapent ethyl) is purified EPA only — a prescription medicine proven in REDUCE-IT to cut major heart events by 25% in the right patient. They are not interchangeable. If your doctor recommends Vascepa, get the prescription — do not substitute OTC fish oil.
Comfort Measures at Home (No Medication Needed)
These simple steps support healing and ease symptoms. Use them alongside any medication your doctor prescribes.
- Make vegetables and whole grains the center of every meal — not a side dish. Beans and lentils several times a week.
- Replace sugary drinks with water or unsweetened sparkling water. Juice and soda are among the fastest ways to raise TG.
- Choose whole fruit over fruit juice. The fiber slows the sugar absorption and has far less impact on TG.
- Eat fish twice a week — salmon, mackerel, sardines, tuna, or trout. These contain omega-3 fats that lower TG naturally.
- Limit alcohol to no more than 1 drink per day for women, 2 for men. If TG are above 500, stop completely until they come down.
- Walk 30 minutes a day, 5 days a week. A 10-minute walk after meals blunts the post-meal TG spike.
- Lose weight slowly — even 5 to 10 percent of body weight makes a big difference. Crash diets are not sustainable.
- Read food labels for added sugar. Look for 'cane sugar,' 'high-fructose corn syrup,' 'dextrose,' or 'maltose' — all raise TG just as fast.
- Sleep 7 to 8 hours per night. Poor sleep raises TG, blood pressure, and blood sugar all at once.
Risks, Benefits, and Alternatives
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
Every choice has trade-offs. Use this table to start the shared decision conversation with your care team.
| Option | Risks | Benefits | Alternatives |
|---|---|---|---|
| Lifestyle only (diet, exercise, weight loss) | Requires sustained effort. May not be enough if TG are very high or causes are genetic. Takes 8 to 12 weeks to see numbers shift. | Lowers TG 20 to 40 percent. Also improves blood sugar, blood pressure, and weight. No side effects. Benefits every organ system. | Add medicine if TG stay above 500 or if ASCVD risk is high. |
| Icosapent ethyl (Vascepa) 4 g/day | Prescription-only, often expensive (prior auth required). Minor: fishy taste, GI upset, small rise in atrial fibrillation risk (REDUCE-IT: +5 vs. +3.9 per 100 patients). NOT a substitute for lifestyle change. | REDUCE-IT: 25% relative reduction in major heart events (heart attack, stroke, CV death, unstable angina) in statin-treated high-risk patients with TG 135-499. Beyond just TG lowering. | OTC fish oil (not proven for events). Prescription Lovaza (lowers TG but no proven MACE benefit). Fibrate if TG over 500. |
| Fenofibrate | May raise creatinine (check kidney function). Rare muscle risk if combined with high-dose statin. Does NOT reliably cut heart events (PROMINENT with pemafibrate was neutral in 2022). | Lowers TG 30 to 45 percent. Primarily used to prevent pancreatitis when TG exceed 500. ACCORD-Lipid showed a possible benefit in patients with diabetes + high TG + low HDL. | Icosapent ethyl if MACE reduction is the goal and TG are 135-499 on a statin. Prescription omega-3 for TG lowering alone. |
| Doing nothing | VLDL remnants continue building plaque over years. If TG are above 500, risk of acute pancreatitis — a painful, potentially life-threatening emergency — remains elevated. | No cost or side effects today. | Lifestyle change costs nothing and carries only benefit. Even cutting one sugary drink per day can move the number. |
Common Misconceptions
| Myth | Reality |
|---|---|
| "My LDL is fine, so my triglycerides do not matter." | FALSE. Triglycerides travel on VLDL. When VLDL delivers its fat, it leaves remnant particles packed with cholesterol — and those remnants drive plaque. You can have a 'normal' LDL and still have a high-risk lipid profile if TG and non-HDL are elevated. |
| "OTC fish oil is the same as Vascepa." | FALSE — this is one of the most important distinctions in lipid medicine. Vascepa is purified EPA (icosapent ethyl). OTC fish oil is a mixture of EPA + DHA, with many impurities, and has NOT been shown to cut heart events in major trials. REDUCE-IT proved Vascepa works — not OTC fish oil. |
| "High triglycerides only come from eating too much fat." | Actually, added sugar, refined carbohydrates, and alcohol are bigger drivers than dietary fat. The liver converts excess carbohydrates and alcohol into TG and packs them into VLDL. A low-fat diet rich in white rice and fruit juice can still push TG up. |
| "If TG is high, fibrates will protect my heart." | Not proven across the board. Fenofibrate is used mainly to prevent pancreatitis when TG exceeds 500 mg/dL. The 2022 PROMINENT trial of pemafibrate showed no reduction in heart events despite lowering TG. The only agent with proven MACE reduction for high TG is icosapent ethyl (Vascepa) in statin-treated patients. |
| "High triglycerides are always my fault — it is just my diet." | Genetics play a real role. Familial hypertriglyceridemia and familial chylomicronemia syndrome (FCS) cause high TG regardless of diet. Certain medicines (steroids, estrogen, thiazides) and medical conditions (hypothyroidism, diabetes, kidney disease) are also major causes that are not lifestyle-related. |
| "I only need to check TG if I have heart disease." | TG should be part of every routine lipid panel starting at age 20 (or earlier with family history or obesity). High TG often accompanies insulin resistance, which starts silently years before diabetes is diagnosed. |
| "Pancreatitis from high TG is just abdominal pain — not serious." | Acute pancreatitis is a medical emergency. It can cause life-threatening complications including organ failure, infected tissue death (necrotizing pancreatitis), and prolonged ICU stays. TG above 1,000 mg/dL make this a realistic risk after a single high-fat meal or alcohol episode. |
Possible Complications
Knowing what can go wrong helps you spot problems early. Most complications are uncommon, especially with treatment.
| Where / What | What Can Happen |
|---|---|
| Atherosclerosis (plaque buildup) | VLDL remnants carry cholesterol into artery walls. Even with normal LDL, persistently high TG raises non-HDL and drives silent plaque accumulation over years. |
| Heart attack and stroke | ASCVD events are the most common long-term complication. High TG compound risk — especially when combined with low HDL, high blood pressure, or diabetes (metabolic syndrome pattern). |
| Acute pancreatitis | At TG above 500 mg/dL, fat particles can block tiny pancreatic vessels and trigger inflammation. Risk rises sharply above 1,000 mg/dL. Symptoms: severe upper-belly pain radiating to the back, nausea, vomiting. Call 911 or go to the ER immediately. |
| Type 2 diabetes | High TG is often an early sign of insulin resistance, which precedes type 2 diabetes by years. Treating TG and improving lifestyle may slow or prevent progression to diabetes. |
| Non-alcoholic fatty liver disease (NAFLD) | The same processes that cause high TG — excess calories, insulin resistance — also deposit fat in the liver. NAFLD can progress to cirrhosis in some patients. |
| Eruptive xanthomas | At very high TG levels (over 1,000), fat can deposit under the skin as small yellow bumps called eruptive xanthomas, typically on the buttocks, shoulders, and thighs. They resolve when TG comes down. |
Very High Triglycerides and Pancreatitis
- When TG exceed 500 mg/dL, pancreatitis risk rises sharply. Above 1,000, a single high-fat meal or a night of drinking can set it off.
- Symptoms: sudden, severe pain in the upper belly or back, nausea, and vomiting. Go to the ER right away. Do not drive yourself.
- Hospital treatment: IV fluids, nothing by mouth, pain medicine, and sometimes IV insulin or plasmapheresis to pull TG out of the blood fast.
- Prevention: stop alcohol if TG are above 500. Cut dietary fat below 15 percent of calories short-term — this cuts the chylomicron load. Restart fenofibrate or prescription omega-3 if you have been prescribed them.
- Familial chylomicronemia syndrome (FCS) is the genetic extreme. FCS patients lack the enzyme that clears TG from blood. TG can exceed 5,000 mg/dL. These patients need a lipid specialist.
- If you have had TG-induced pancreatitis before, wear a medical alert bracelet. Carry a letter from your doctor for ER staff.

Icosapent Ethyl (Vascepa) — the REDUCE-IT Evidence
- Vascepa (icosapent ethyl) is a purified EPA prescription medicine. Take 4 capsules (4 g) per day with meals.
- REDUCE-IT enrolled 8,179 patients already on a statin with TG between 135 and 499 mg/dL and either known ASCVD or diabetes plus one more risk factor.
- Result: Vascepa cut the primary endpoint (CV death, heart attack, stroke, unstable angina, or bypass) by 25 percent vs. placebo over 4.9 years (Bhatt et al., NEJM 2019).
- The benefit likely goes beyond TG lowering. Vascepa has anti-inflammatory and membrane effects. OTC fish oil and Lovaza have NOT shown this same benefit in trials.
- One caution: REDUCE-IT found more atrial fibrillation hospitalizations with Vascepa (5.3% vs. 3.9%). Discuss this with your doctor if you have a history of AF.
- Good candidate: high-risk patient on a statin, TG 135 to 499, with prior ASCVD or diabetes plus one more risk factor.
- Not the right choice: if your goal is TG lowering to prevent pancreatitis (use fenofibrate), or if you want an OTC supplement (that is a different product entirely).
Points to Know
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
If you remember nothing else, remember these key points.
- Triglycerides are checked on every standard lipid panel — you do not need a separate test.
- Normal is below 150 mg/dL. High is 200 to 499. Very high (500 or higher) raises pancreatitis risk — tell your doctor immediately.
- High TG adds heart risk through VLDL remnants — even when LDL looks normal. Check your non-HDL cholesterol too.
- Lifestyle is the first and most powerful step: cut sugar and refined carbs, limit alcohol, lose weight, and exercise.
- OTC fish oil is NOT the same as Vascepa (icosapent ethyl). Only Vascepa has been proven in a large trial to cut heart events.
- Fibrates (fenofibrate) lower TG well but are used mainly to prevent pancreatitis — not proven to cut heart events on their own.
- Very high TG (above 500 mg/dL) is an urgent medical situation — do not wait for your next appointment if your level is in this range.
- Genetics, thyroid disease, diabetes, kidney disease, and some medicines all cause high TG — it is not always a lifestyle issue.
When to Call Us — and When to Call 911
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
If you are not sure, call. We would rather hear from you twice than miss a real problem.
- Call 911 or go to the ER if you have sudden, severe upper-belly pain (especially radiating to the back) with nausea or vomiting. This could be pancreatitis — a medical emergency if TG are very high.
- Call our office (727-943-5200) if your triglycerides are above 500 mg/dL. Do not wait for your next scheduled visit — very high TG requires urgent management.
- Call us if your last lipid panel was more than a year ago and you have diabetes, obesity, or a family history of high TG.
- Call us before starting any new medicine — corticosteroids, estrogen, certain blood-pressure medicines, and retinoids can all push TG higher.
- Call us if you have been prescribed Vascepa (icosapent ethyl) and develop irregular heartbeat symptoms (palpitations, racing heart, shortness of breath). REDUCE-IT showed a small rise in atrial fibrillation risk.
- Ask us about repeat testing 8 to 12 weeks after any major diet change, new medicine, or dose adjustment. TG respond quickly to lifestyle — seeing the number improve is motivating.
- Ask about a non-HDL cholesterol target. If your LDL is at goal but non-HDL is still high, you may have residual TG-remnant risk worth treating.
