High Triglycerides: Causes, Symptoms, Diagnosis & How to Reduce It 

Introduction

You may be confused if your blood test results show high triglyceride levels, especially if you have no visible symptoms. Triglycerides are a form of fat found in the blood that your body uses for energy¹. However, when their levels rise too high, they might raise the risk of serious health issues such as heart disease, stroke, fatty liver disease, and pancreatitis².

The good news is that high triglycerides can often be managed with the right lifestyle changes, healthy eating habits, and timely medical care. In this blog, you will learn what high triglycerides mean, their causes and symptoms, how they are diagnosed, and effective ways to reduce them naturally and medically. 

What Does High Triglycerides Mean?

High triglycerides means that there is an excess amount of triglycerides, a type of fat (lipid), circulating in your blood.  

Our bodies use calories for functioning and physical activity, which are supplied from the food we eat. Excess calories that are not utilised by the body get converted into triglycerides, which are not needed immediately. These triglycerides are stored in fat cells and used for energy when required¹.

Triglycerides are important for normal body function, but having too much of them in the blood can become harmful. High triglyceride levels are frequently associated with unhealthy lifestyle practices such as consuming too much sweet or fatty food, lack of physical activity, smoking, consuming excessive alcohol, etc². They can also occur due to conditions like diabetes, thyroid disorders, kidney disease, or due to certain medications¹.

In most cases, high triglycerides do not cause noticeable symptoms², which is why many people discover them only during a routine blood test called a lipid profile. When triglyceride levels remain high for a long time, fatty deposits can build up in blood vessels, making it harder for blood to flow properly (atherosclerosis). This increases the risk of heart-related diseases and other complications³. Very high triglyceride levels can also affect the pancreas, leading to a painful condition called pancreatitis².

High Triglycerides Signs and Symptoms

• Yellow-red bump like fatty deposits under the skin (eruptive xanthomatosis). Usually seen on shoulders, thighs, legs, etc⁴ 
• Unexplained weight gain or obesity²
• Stomach pain, memory problems for a short period, and skin becoming red or warm after drinking alcohol (caused when excess fat builds up in the blood- multifactorial chylomicronaemia syndrome)²  
• Neurological symptoms like burning sensation, tingling, numbness or weakness on feet, legs, hands or arms (mainly caused when high triglycerides linked to diabetes)⁵ 
• Abdominal pain, vomiting or nausea (often linked with high glycerides causing pancreatitis)^2,6 

Since symptoms are often absent, regular health check-ups and lipid profile tests are important for early detection. 

What Causes High Triglycerides?

High triglycerides can be caused by an unhealthy lifestyle, certain medical problems, drugs, or genetics. Common causes include: 

1. Lifestyle Factors

• Diet

Consuming foods rich in calories regularly, especially sugary and high fat foods, can cause an elevation in triglycerides. 

• Exercise

Lack of physical activity can contribute to increased triglyceride retention in the body as less fat is burned as energy. 

• Smoking

Smoking can raise triglyceride levels by affecting the way your body processes fats and increasing unhealthy fat buildup in the blood. 

• Alcohol

Excessive alcohol consumption can increase the levels of triglycerides in the body^1,2.

• Stress

Long-term stress can affect the hormonal balance and alter the body’s way of how fats are utilised; this can increase triglyceride levels⁷.

2. Medical Conditions

• Diabetes

Poorly controlled diabetes or insulin resistance can cause high triglycerides in the body^1,8.

• Liver or Kidney Disease^1,2

Liver or kidney disease can raise triglyceride levels by reducing the body’s ability to remove fats from the blood. 

• Thyroid Problems

Thyroid issues, mainly hypothyroidism, a condition where less thyroid hormones are produced, can reduce the metabolism, thereby altering the processing of fats and increasing triglyceride levels in the body^3,9 

• Obesity

Obesity can raise triglyceride levels by causing the body to store fat around the abdomen³.

3. Certain Medications

 Certain medications such as corticosteroids, hormonal pills (oestrogen), antivirals (ritonavir), antipsychotics, water pills (diuretics), BP medications (beta blockers) can increase triglycerides in the body^2,10.

4. Genetics

Some genetic disorders can also cause high triglyceride levels. Examples: Familial hypertriglyceridemia and combined hyperlipidaemia³.

Identifying the reasons for high triglycerides are important for choosing the right treatment and lifestyle changes to lower triglyceride levels effectively. 

Normal vs High Triglyceride Levels

Triglyceride levels are measured through a blood test known as a lipid profile. These levels help doctors determine how much fat is in your blood and whether it raises your risk of heart disease and other health issues. 

The following is a table which shows the ranges of triglycerides¹:

If you have normal triglycerides, it may suggest your body is successfully consuming and storing fats for energy without allowing excess fat to accumulate in the bloodstream. People who have normal triglyceride levels are less likely to have heart disease, stroke, or pancreatitis, especially if their other cholesterol levels are also within healthy range¹¹. 

High triglyceride levels imply that there is too much fat circulating in the blood. This usually occurs when the body consumes or retains more calories than it burns. Over time, extra fats can harden or restrict blood vessels, increasing the risk of cardiovascular disease².

Triglyceride levels above 500 mg/dL can increase the risk of pancreatic inflammation (pancreatitis), resulting in severe stomach pain. Very high levels may also alter blood vessels in the eyes, and cause skin changes on the chest, back, arms, or legs. Extremely high triglyceride levels (above 1,500 mg/dL) can sometimes stop the body from properly breaking down fats, a very dangerous condition called multifactorial chylomicronaemia syndrome².

Therefore, checking triglyceride levels regularly is important to identify potential health risks early. People with diabetes, obesity, heart disease, thyroid disorders, or a family history of lipid disorders may need more frequent monitoring².

Note: Triglyceride or lipid profile levels should be interpreted by a qualified doctor, as the results might vary depending on age, medical history, medications, and other personal factors. 

Blood Tests to Diagnose High Triglycerides

High triglyceride levels are detected with a simple blood test known as a lipid profile, which analyses the amount of fats (lipids) in the blood, including triglycerides, cholesterol (LDL, HDL), and total cholesterol. This test allows doctors to determine your risk of heart disease and other problems¹².

What the Triglyceride Blood Test Involves?

Your doctor will collect a simple blood sample, usually from an arm vein, for the test. It is a short, very minimally invasive process. The obtained sample is then analysed in a laboratory to identify the concentration of triglycerides in the bloodstream, as well as other lipid parameters¹². 

Fasting Requirements for the Test

For accurate triglyceride results, fasting is generally recommended: 

• Fasting duration: 9-12 hours before the test¹²
• What is allowed: Only water during the fasting period 
• What to avoid: Food, tea, coffee, juice, alcohol, smoking, etc. before the test¹³ 

Note: Taking a test without fasting can show variations in values of triglycerides and other lipids. Talk to your doctor if you are taking any medications or supplements, as they can also interfere with the result. Also, do not stop any medications without your doctor’s permission¹².

When Should You Take the Test?

Your doctor might suggest a lipid profile test in the following situations: 

• As part of a routine health check-up (typically every few years for adults) 
• If you have risk factors such as obesity, diabetes, high blood pressure, smoking habit or a sedentary lifestyle¹⁴
• If there is a family history of heart disease or lipid disorders²
• To monitor the effectiveness of treatment for high cholesterol or triglycerides¹⁴

Your doctor might suggest taking the test in the morning following an overnight fast, making it easier to meet the fasting requirement and ensuring consistent and reliable findings¹⁵.

High Triglycerides Treatment

High triglyceride levels are addressed based on their severity and the individual’s overall risk of heart disease or pancreatitis. Doctors may give drugs to help lower triglycerides and avoid problems. Common medications include the following: 

• Statins: Commonly used medications for high cholesterols and triglycerides. 
• Prescription Omega-3 Fatty Acids: These are high-dose fish oil–based medicines that help reduce triglyceride production. 
• Fibrates: One of the effective medicines to lower triglycerides and cholesterol in blood. 

Doctors may also address conditions like diabetes or thyroid issues that trigger excessive triglyceride levels. Managing these conditions helps improve overall lipid levels².

Diet for High Triglycerides

A healthy diet plays an important role in managing high triglyceride levels. Certain foods can help improve fat metabolism, support heart health, and reduce excess triglycerides in the blood. The following are few among them: 

• Complex Carbohydrates: Carbs such as oats, brown rice, and other whole grains should be chosen as they are rich in fibre, which helps reduce the absorption of fat and sugar in the body, thereby lowering triglyceride and cholesterol levels and reducing blood sugar spikes¹⁶.
• Proteins: Lean protein from sources such as kidney beans, lentils, chickpeas etc. can be consumed. Fatty fishes such as salmon, sardines and mackerel can be a great choice as they are rich in omega-3 fatty acids, which help lower triglyceride production³.
• Green Leafy Vegetables: Plenty of leafy greens such as spinach, kale, and other leafy greens should be included in the diet as these are low in calories and high in fibre and antioxidants. They may help improve metabolism and support overall cardiovascular health¹⁷.
• Healthy Fats: Sources of healthy fats such as fish, nuts and seeds like almonds, walnuts, chia seeds, flaxseeds, fruits like avocado, unsaturated oils like canola, sunflower, soyabean etc. can be included as they may help reduce the triglycerides and other bad fats. They also support good cholesterol (HDL) levels when eaten in moderation^2,18.

Food to Avoid with High Triglycerides

High triglyceride levels can be worsened by certain foods, so it is important to limit or avoid them to help maintain better blood lipid control. Here are few among them: 

• Sugary foods and Sweets: These include cakes, candies, chocolates, and desserts, which are high in sugar. The body converts them into triglycerides when consumed in excess².
• Refined Carbohydrates: These include white bread, pasta, noodles, etc., which digest fast and contribute to high triglycerides in the body¹⁹.
• Fried or Processed Foods: These include burger, processed meat, French fries, chips, etc., which are high in fat and triglycerides¹⁹. 
• Alcohol: Alcohol can significantly increase triglycerides, especially when consumed regularly or in large amounts^1,2. 

How to Reduce High Triglycerides Naturally?

High triglyceride levels can typically be reduced with easy lifestyle adjustments that enhance fat management and general heart health. These include the following: 

• Dietary Adjustments: Reducing sugar, refined carbohydrates and unhealthy fats while including more fibre, omega-3 rich foods and healthy fats can help lower triglyceride levels^2,3. 
• Healthy Lifestyle Habits: Avoiding alcohol, quitting smoking, getting proper sleep and managing stress can significantly help manage triglycerides in the body².
• Healthy Body Weight: Achieving and maintaining an optimal weight helps reduce excess fat in the blood and lowers triglyceride levels naturally^1,2.
• Physical Activity^1,2,: Regular exercise helps burn excess calories, improves metabolism, and supports better triglyceride control in the blood. 

When to Consult a Doctor?

You should consult a doctor if: 

• Your blood test shows high triglyceride levels 
• You have diabetes, obesity, or high blood pressure^1,2 
• You have symptoms such as chest pain, abdominal pain, or breathlessness²⁰ 
• You have a family history of heart disease¹⁴
• Lifestyle changes are not improving your triglyceride levels 

Early diagnosis and treatment may help avoid serious complications and improve long-term health.
