Triglycerides

What it is

Triglycerides are a type of fat, also known as a lipid, that your body makes. They are the most common type of fat found in your blood and are a major source of energy for your body. When you eat, your body converts any calories it doesn't need to use right away into triglycerides. These triglycerides are stored in your fat cells. Later, hormones release triglycerides for energy between meals.

Think of them like this: when you eat, your body takes in energy from food. If you eat more calories than you need at that moment, your body stores the excess energy as fat. Triglycerides are the main form of this stored fat. They circulate in your bloodstream, ready to be used when your body needs energy, for example, between meals or during exercise.

Why it matters

Having a healthy level of triglycerides in your blood is important for your overall health, particularly for your heart. While triglycerides are essential for providing energy, consistently high levels can be a sign that your body isn't processing fats efficiently.

High triglyceride levels are often linked to other conditions that increase your risk of heart disease, such as high blood pressure, low levels of 'good' cholesterol (HDL), and being overweight or obese. This combination of factors is sometimes referred to as metabolic syndrome, and it significantly raises the chances of developing problems like heart attacks and strokes.

Monitoring your triglyceride levels can therefore be a useful part of understanding your cardiovascular health.

What can cause it to be high or low

Several factors can influence your triglyceride levels, leading them to be higher or lower than the typical range.

Factors that can lead to higher triglyceride levels include:

• Diet: Eating a diet high in carbohydrates, sugars, and unhealthy fats can raise triglyceride levels. Consuming excessive calories, especially from sugary drinks and processed foods, is a common contributor.
• Weight: Being overweight or obese is strongly associated with higher triglycerides.
• Lack of physical activity: Not being physically active can lead to higher triglyceride levels.
• Alcohol consumption: Drinking alcohol, particularly in large amounts, can significantly increase triglycerides.
• Certain medical conditions: Conditions like type 2 diabetes, an underactive thyroid (hypothyroidism), and kidney disease can affect triglyceride levels.
• Medications: Some medications, such as certain diuretics, beta-blockers, and hormone therapies, can sometimes raise triglycerides.
• Genetics: In some cases, a family history of high triglycerides can play a role.

Factors that can lead to lower triglyceride levels include:

• Healthy diet: Eating a balanced diet rich in fruits, vegetables, whole grains, and healthy fats (like those found in fish, nuts, and olive oil) can help lower triglycerides.
• Regular exercise: Consistent physical activity can help reduce triglyceride levels.
• Weight loss: Losing excess weight can have a positive impact on triglyceride levels.
• Limiting alcohol: Reducing or avoiding alcohol intake can lower triglycerides.
• Certain medications: Some medications used to treat high cholesterol, like statins, can also lower triglycerides.

It's worth noting that very low triglyceride levels are less common and usually not a cause for concern unless they are extremely low and associated with other health issues.

Lifestyle factors that may help

Making certain lifestyle changes can be very beneficial for managing your triglyceride levels. These are often the first steps recommended to help bring them into a healthier range.

• Dietary adjustments: Focusing on a diet that is lower in refined carbohydrates, added sugars, and saturated and trans fats is key. This means reducing your intake of sugary drinks, sweets, cakes, biscuits, and processed foods. Instead, incorporating more fruits, vegetables, whole grains, lean proteins, and healthy fats from sources like oily fish, nuts, seeds, and olive oil can be helpful.
• Regular physical activity: Aiming for regular exercise can make a significant difference. This could include activities like brisk walking, jogging, swimming, cycling, or dancing. The general recommendation is to aim for at least 150 minutes of moderate-intensity aerobic activity per week.
• Weight management: If you are carrying excess weight, even a modest weight loss of 5-10% can have a positive effect on your triglyceride levels.
• Limiting alcohol: Reducing your alcohol consumption, or avoiding it altogether, can be a very effective way to lower triglycerides, especially if you drink regularly or in larger quantities.

Discussing these lifestyle approaches with your GP can help you create a plan that's tailored to your individual needs and preferences.

Questions to discuss with your GP

When you have your triglyceride levels checked, it's a good opportunity to have a conversation with your GP about what the results mean for you. Here are some questions you might consider asking:

• What were my triglyceride levels, and how do they compare to the recommended ranges?
• Are my triglyceride levels considered high, and what are the potential health implications for me specifically?
• Are there any underlying medical conditions or lifestyle factors that might be contributing to my triglyceride levels?
• What specific dietary changes would you recommend for me to help manage my triglycerides?
• What type and amount of physical activity would be most beneficial for my triglyceride levels?
• Are there any other tests or checks you would recommend to assess my overall heart health?
