What Causes High Blood Pressure and High Blood Fat?

High blood pressure (hypertension) and high blood fat (high cholesterol and triglycerides) are two of the most common — and most preventable — risk factors for heart attack, stroke, and vascular disease. They often occur together and usually cause no symptoms, which is why they are sometimes called "silent" conditions.

What causes high blood pressure?

Blood pressure is the force of blood pushing against artery walls. It can rise due to a mix of factors:

• Diet high in salt and processed foods
• Excess weight and lack of physical activity
• Stress and poor sleep
• Smoking and excessive alcohol
• Genetics and increasing age
• Underlying conditions such as kidney disease or diabetes

What causes high blood fat?

Cholesterol and triglycerides are fats carried in the blood. Levels rise when:

• The diet is high in saturated and trans fats
• Physical activity is low
• There is excess weight, particularly around the abdomen
• There is a family history of high cholesterol
• Conditions such as diabetes or an underactive thyroid are present

Why they matter for your blood vessels

Over time, high pressure and excess fat damage the inner lining of arteries. Fatty deposits (plaque) build up, narrowing the vessels and reducing blood flow. This is the root of most heart attacks, strokes, and peripheral arterial disease.

How to bring them under control

1. Eat well — more vegetables, fruit, whole grains, and healthy fats; less salt, sugar, and processed food.
2. Move daily — aim for regular, moderate activity such as brisk walking.
3. Maintain a healthy weight.
4. Stop smoking and limit alcohol.
5. Take prescribed medication consistently if your doctor recommends it.
6. Monitor regularly so changes are caught early.

The takeaway

Because they rarely cause symptoms, the only way to know your numbers is to check them. Simple lifestyle changes — combined with medication when needed — can dramatically lower your risk. If you have high blood pressure or cholesterol, a vascular assessment can also check whether your arteries have been affected.
