High triglycerides are a common but often silent health concern for many Canadians. Triglycerides are a type of fat found in your blood, and when levels stay too high for too long, they can increase your risk of heart disease, stroke, and diabetes. The good news is that lifestyle changes — and sometimes medication — can bring your levels back to a healthy range. This article explains what high triglycerides are, what causes them, and what you can do about them.

What Are High Triglycerides?

Triglycerides are the most common form of fat in the human body. After you eat, your body uses the calories it needs for immediate energy. Any extra calories — whether they come from fat, carbohydrates, or protein — get converted into triglycerides and stored in fat cells for later use.

When you consistently eat more calories than your body burns, your triglyceride levels rise. In normal amounts, triglycerides are healthy and useful. However, when levels climb too high, they become a warning sign worth paying attention to.

Doctors measure triglycerides as part of a routine blood test called a lipid panel (also called a lipid profile). This is the same test that checks your cholesterol. According to Health Canada, getting regular blood work through your family doctor is one of the best ways to catch problems like this early.

Triglyceride Level Ranges

Understanding your numbers helps you take action. Here is how triglyceride levels are classified (measured in milligrams per decilitre, or mg/dL):

  • Normal: Less than 150 mg/dL

  • Borderline high: 150–199 mg/dL

  • High: 200–499 mg/dL

  • Very high: 500 mg/dL or above

Levels above 200 mg/dL are considered too high and require attention. Levels above 500 mg/dL are especially serious and can cause dangerous complications.

How High Triglycerides Connect to Heart Health

Researchers are still studying the exact link between high triglycerides and heart disease. However, high triglyceride levels are a key part of a condition called metabolic syndrome. This is a group of health problems that together raise your risk of heart attack, stroke, and type 2 diabetes.

Metabolic syndrome includes the following:

  • High triglycerides

  • Low HDL cholesterol (the “good” cholesterol)

  • High blood pressure

  • High blood sugar

  • Excess weight around the waist

If you have several of these conditions at the same time, your overall cardiovascular risk increases significantly. Therefore, treating high triglycerides is rarely about one number alone — it is about looking at your overall health picture.

Common Causes of High Triglycerides

Several factors can push your triglyceride levels above the healthy range. Some are related to lifestyle, while others involve underlying medical conditions or medications.

Lifestyle and Diet

The most common causes of high triglycerides are obesity and poorly controlled type 2 diabetes. Eating a diet high in refined carbohydrates — such as white bread, pasta, pastries, and sugary drinks — can cause levels to rise quickly. Excess alcohol is another major trigger. Even occasional heavy drinking can cause sudden, sharp spikes in triglyceride levels.

Being physically inactive also plays a big role. A sedentary lifestyle combined with a high-calorie diet is one of the most reliable ways to push triglyceride levels into the unhealthy range.

Medical Conditions

Certain health conditions can raise triglyceride levels even in people who eat well and exercise regularly. These include:

  • Hypothyroidism — an underactive thyroid gland that slows metabolism

  • Kidney disease — affects how the body processes fats

  • Poorly controlled diabetes — high blood sugar contributes to fat buildup in the blood

  • Inherited lipid disorders — some people are genetically prone to high triglycerides

For this reason, when a doctor finds high triglycerides, they will often check for these underlying conditions as well. As noted by the Mayo Clinic’s guide to triglycerides, treating the root cause is just as important as treating the number itself.

Medications

Some common medications can raise triglyceride levels as a side effect. These include:

  • Oral contraceptives (birth control pills)

  • Estrogen therapy used during menopause

  • Diuretics (water pills)

  • Beta-blockers (such as metoprolol)

  • Corticosteroids

If you take any of these medications and have high triglycerides, talk to your doctor. Do not stop any medication on your own without medical advice.

Symptoms of High Triglycerides

High triglycerides usually cause no symptoms at all. This is why so many Canadians do not know they have a problem until a routine blood test reveals it. In most cases, the first sign is an abnormal result on a lipid panel ordered by a family doctor or at a walk-in clinic.

When Symptoms Do Appear

In rare cases, very high triglyceride levels can lead to a serious complication called pancreatitis — inflammation of the pancreas. This condition causes sudden, severe abdominal pain, nausea and vomiting, loss of appetite, and fever. Pancreatitis is a medical emergency and requires immediate care.

In people with a genetic form of high triglycerides, fatty deposits called xanthomas may appear under the skin. These are yellowish, waxy bumps that tend to form on the elbows, knees, or buttocks. However, this is uncommon in the general population.

Because high triglycerides rarely cause obvious symptoms, regular blood work is your most important tool for catching this condition early.

Treatment and Lowering High Triglycerides

The first line of treatment for high triglycerides is almost always lifestyle change. In many cases, this alone is enough to bring levels back to a healthy range. Medications are added when lifestyle changes are not enough or when the risk of heart disease is already high.

Lifestyle Changes That Help

Making changes to your daily habits can have a powerful effect on your triglyceride levels. Here are the most effective steps:

  • Lose excess weight: Even a modest weight loss of 5–10% of your body weight can make a meaningful difference.

  • Reduce refined carbohydrates: Cut back on white bread, sugary cereals, pastries, and sweetened beverages.

  • Limit alcohol: Even moderate drinking can raise triglyceride levels. Some people may need to stop drinking entirely.

  • Increase physical activity: Aim for at least 150 minutes of moderate exercise per week, as recommended by Canadian physical activity guidelines.

  • Choose healthier fats: Replace saturated fats (found in fatty meats and full-fat dairy) with unsaturated fats found in olive oil, avocados, and nuts.

  • Eat more fibre: Vegetables, legumes, and whole grains all help manage blood fat levels.

  • Quit smoking: Smoking worsens cardiovascular risk and should be stopped as part of any heart-health plan.

According to Healthline’s overview of triglyceride reduction strategies, dietary changes combined with regular exercise consistently produce the best results for most people.

Medications for High Triglycerides

When lifestyle changes are not enough, your doctor may consider medication. This is especially true if you already have heart disease or are at high risk. Common drug options include fibrates, niacin, omega-3 fatty acid supplements, and statins.

In Canada, your family doctor or a specialist may also first focus on lowering LDL cholesterol (the “bad” kind) and raising HDL cholesterol (the “good” kind). Research shows this approach most clearly reduces the risk of heart attack and death. Lowering triglycerides alone may provide additional benefit, but the evidence is strongest for managing overall cholesterol levels first.

When to See a Doctor

You should ask your family doctor for a lipid panel if you are 40 or older, or sooner if you have risk factors like obesity, diabetes, or a family history of heart disease. Provincial health plans across Canada generally cover this routine blood test when ordered by a physician.

If you do not have a family doctor, a walk-in clinic can order a lipid panel and refer you for follow-up care. Do not wait for symptoms — high triglycerides are a silent condition that is much easier to manage when caught early.

Seek emergency care immediately if you develop sudden severe abdominal pain, nausea, and vomiting. These could be signs of pancreatitis, which requires urgent treatment.

Always speak with a qualified healthcare provider before making changes to your diet, exercise routine, or medications. The information in this article is for general educational purposes only.

Frequently Asked Questions About High Triglycerides

What level of triglycerides is considered dangerous?

Triglyceride levels above 200 mg/dL are considered high and warrant medical attention. Levels above 500 mg/dL are very high and can lead to serious complications such as pancreatitis. If your results show high triglycerides, speak with your doctor about the right treatment plan for you.

Can you lower high triglycerides without medication?

Yes, many people can significantly lower high triglycerides through lifestyle changes alone. Reducing refined carbohydrates, limiting alcohol, losing weight, and increasing physical activity are all highly effective strategies. However, some people also need medication, especially if levels are very high or other cardiovascular risk factors are present.

What foods cause high triglycerides?

Foods that are most likely to raise triglyceride levels include sugary drinks, white bread, pastries, candy, and alcohol. High triglycerides are strongly linked to diets rich in refined carbohydrates and added sugars. Reducing these foods and replacing them with fibre-rich vegetables, whole grains, and healthy fats can help bring levels down.

Do high triglycerides cause symptoms?

In most cases, high triglycerides cause no noticeable symptoms at all. Most people only find out their levels are elevated through a routine blood test called a lipid panel. This is why regular check-ups with your family doctor or at a walk-in clinic are so important.

Are high triglycerides the same as high cholesterol?

No, but they are related. Both triglycerides and cholesterol are types of fat found in the blood, and both are measured on the same lipid panel blood test. High triglycerides often appear alongside high LDL cholesterol and low HDL cholesterol, which together can significantly raise your risk of heart disease.

How quickly can you lower high triglycerides?

With consistent lifestyle changes, many people see a meaningful drop in their triglyceride levels within a few weeks to a few months. Reducing alcohol and refined carbohydrates tends to produce some of the fastest results. Your doctor can monitor your progress with follow-up blood work and adjust your treatment plan as needed.
