Hyperlipidemia early on does not show specific clinical symptoms and is typically indicated by increased blood lipid levels during physical examinations. If it is not taken seriously and left untreated, long-term hyperlipidemia can lead to noticeable clinical symptoms. Mild cases may experience fatigue and weakness. Prolonged elevated blood lipid levels can cause the blood to become viscous and flow slowly, affecting the supply of blood to the heart, leading to palpitations and shortness of breath that worsen with activity. It can also affect blood supply to the brain, causing irritability, restless sleep, frequent nightmares, and even sleepiness. Therefore, it is crucial to treat hyperlipidemia actively upon diagnosis to prevent it from impacting the blood supply to vital organs.
