High Cholesterol's Effects on Circulation & Breathing

Elevated LDL cholesterol harms the circulatory system and indirectly affects respiration.

Circulatory System

• Atherosclerosis – Plaque narrows arteries, restricting flow.
• Heart attack – Plaque rupture → clot blocks coronary artery.
• Stroke – Cerebral artery plaque/clot blocks brain blood flow.
• Peripheral Artery Disease – Limb artery narrowing causes pain/numbness.

Respiratory System (Indirect)

• Sleep apnea association – High cholesterol linked to obstructive sleep apnea (airway blockage during sleep).
• COPD link – Slightly increased COPD risk; mechanisms under study.

Manage cholesterol via diet, exercise, and prescribed medication to reduce cardiovascular/respiratory risks.
