Your blood’s ability to clot properly is essential, but too much clotting protein can be dangerous. Fibrinogen is a key player in blood clot formation, and elevated levels can increase your risk of heart attack and stroke. South Asians typically have 15-20% higher fibrinogen levels compared to Western populations, potentially explaining our higher rates of early heart attacks. Think of fibrinogen as the “emergency response team” that’s supposed to repair vessel damage – but when levels are too high, it can create harmful roadblocks in your blood vessels.
Understanding Fibrinogen: The Blood Clotting Protein
What Is Fibrinogen?
Fibrinogen is a protein in your blood that helps with clotting. Think of it as your body’s natural “glue” that stops bleeding when you get a cut.
When you injure yourself, fibrinogen transforms into fibrin, creating a sticky mesh that catches blood cells and forms a clot. This is helpful when you need to heal a wound.
However, too much fibrinogen can be a problem. Like too much glue that makes things stick when they shouldn’t, high fibrinogen can make your blood thicker and more likely to form clots when you don’t need them.
Why It Matters for South Asians
Research shows that South Asians (Indians, Pakistanis, Bangladeshis, Sri Lankans, and Nepalis) often have 15-20% higher fibrinogen levels than Western populations. This is one reason why heart attacks and strokes happen earlier in our community.
Here’s why this matters:
This hidden risk factor helps explain why a seemingly healthy 45-year-old South Asian man might have a heart attack despite normal cholesterol levels.
What Causes Fibrinogen to Rise?
Several factors can increase your fibrinogen levels:
Lifestyle Factors:
Other Causes:
For South Asians, the combination of genetic tendency, vegetarian diets sometimes low in certain nutrients, and modern stressful lifestyles can create the perfect environment for high fibrinogen.
Can You Test for It?
Yes, fibrinogen can be measured with a simple blood test. It’s not part of standard blood work, but you can ask your doctor to include it, especially if:
The test costs about $30-80 and doesn’t require special preparation.
Normal fibrinogen levels are generally between 200-400 mg/dL. Levels above 400 mg/dL may indicate increased risk.
What Can You Do If It’s High?
If your fibrinogen is elevated, there are several natural approaches that may help bring it down:
Food Changes:
Lifestyle Adjustments:
Talk to Your Doctor: Your doctor might recommend additional steps, especially if your levels are very high. Here’s what you might say at your next visit:
“I’ve read that South Asians often have higher fibrinogen levels, which might increase heart risk. Could we check my fibrinogen level to better understand my clotting risk?”
If you’re already on aspirin or other medications, never adjust them without medical guidance.

A cardiovascular risk calculator is a medical tool that estimates your chance of having a heart attack or stroke in the next 10 years.
Think of it as a personalized weather forecast for your heart health—it combines multiple factors about your health to predict future risk.
Risk calculators are built using data from large medical studies that follow thousands of people over many years.
Researchers track who develops heart disease and identify the common factors that increase risk.
These patterns are then turned into mathematical formulas that can predict individual risk.
Key Components:
Most calculators evaluate these core factors:
Risk Categories:
What Your Number Means: A 10% risk means that out of 100 people exactly like you, about 10 will have a heart attack in the next 10 years. It's a probability, not a certainty.
Most widely-used risk calculators were developed using predominantly white populations.
This creates significant problems for South Asians:
Just as weather forecasts are more accurate when they account for local geography and climate patterns,
heart disease risk assessment is more accurate when it accounts for population-specific health patterns.
A good risk calculator doesn't just give you a number—it helps you understand:
Risk assessment is most valuable when it guides action:
Modern risk calculators are becoming more sophisticated:
The future of cardiovascular risk assessment is moving toward truly personalized predictions that account for:
Remember These Important Points:
Bottom Line: A good cardiovascular risk calculator is a powerful tool for understanding and preventing heart disease,
but it works best when designed for your specific population and used alongside professional medical care.
