2. WHY HIGH
CHOLESTEROL IS
BAD?
High cholesterol is considered bad for
several important reasons, primarily
because it significantly increases the risk
of developing cardiovascular diseases,
such as coronary artery disease, heart
attacks, and strokes. Here's why high
cholesterol is considered harmful.
3. ATHEROSCLEROSIS
High levels of LDL (low-density lipoprotein) cholesterol, often referred
to as "bad" cholesterol, can lead to the accumulation of fatty deposits,
known as plaques, in the walls of arteries. These plaques can narrow
and harden the arteries, restricting blood flow to vital organs, including
the heart and brain.
CORONARY ARTERY
DISEASE (CAD)
Atherosclerosis in the coronary arteries, which supply blood to the
heart muscle, can lead to coronary artery disease. Reduced blood flow
to the heart can cause angina (chest pain) or, in severe cases, lead to a
heart attack.
4. STROKE
When atherosclerosis occurs in the arteries leading to the
brain, it can increase the risk of stroke. A stroke occurs
when blood flow to part of the brain is blocked, leading to
brain damage.
PERIPHERAL ARTERY
DISEASE (PAD)
Atherosclerosis can affect arteries in the limbs, leading to
peripheral artery disease. This condition can cause pain and
limited mobility in the legs and feet due to reduced blood flow.
5. INCREASED BLOOD
PRESSURE
High cholesterol can contribute to high blood pressure
(hypertension), which is a significant risk factor for heart
disease and stroke.
RUPTURE OF PLAQUES
Plaques in the arteries can become unstable and rupture, leading to
the formation of blood clots. These clots can block blood flow in
the arteries, causing heart attacks or strokes.
6. COMPLICATIONS
High cholesterol is a major contributor to chronic heart conditions,
including chronic heart failure.
It's important to note that there are two main types of cholesterol
carriers in the blood:
Low-Density
Lipoprotein (LDL)
High-Density
Lipoprotein (HDL)
Often referred to as "bad"
cholesterol because it can
contribute to atherosclerosis
when levels are high.
Often referred to as "good"
cholesterol because it helps
remove excess cholesterol
from the bloodstream and
carry it to the liver for disposal.
7. Fortunately, high cholesterol can often be managed
through lifestyle changes (such as a heart-healthy diet,
regular exercise, and smoking cessation) and, if
necessary, medication prescribed by a healthcare
provider. Regular cholesterol screenings and discussions
with a hyperlipidemia doctor are essential for managing
cholesterol levels and reducing the risk of cardiovascular
diseases
Having high levels of LDL cholesterol and/or low levels of
HDL cholesterol increases the risk of developing
atherosclerosis and related cardiovascular diseases.
