Why is smoking harmful?

Cigarette smoke contains thousands of chemicals. Some of these can damage your blood vessels and heart. Smoking doubles your risk of heart attack and stroke, and recent research shows that smoking just one cigarette a day increases your risk.

Does smoking cause high cholesterol?
  • Smoking makes your LDL cholesterol (bad type) more “sticky” – so it sticks to your arterial walls and clogs them.
  • Smoking lowers HDL cholesterol (a good type), which usually removes cholesterol from the walls of blood vessels.
  • Smoking damages the walls of your arteries and cholesterol accumulates in damaged areas.

These changes mean that your arteries become clogged faster. Smoking also increases your heart rate, narrows your blood vessels and thickens your blood, and reduces its ability to carry oxygen. Blood does not flow easily around your body, your heart has to work harder, and blood clots can form, which can lead to heart attacks and strokes.

How will giving up help?
