Introduction
Narcolepsy may be caused by conditions such as hyperlipidemia, cerebral atherosclerosis, and iron-deficiency anemia. In patients with hyperlipidemia, the blood is more viscous, leading to cerebral ischemia and hypoxia, which results in excessive sleepiness. Insufficient cerebral blood supply due to cerebral atherosclerosis can also cause somnolence. In individuals with iron-deficiency anemia, reduced peripheral red blood cells decrease the body's oxygen-carrying capacity, making them prone to drowsiness.
Generally, hypersomnia may be caused by conditions such as hyperlipidemia, cerebral atherosclerosis, or iron-deficiency anemia, and treatment should be directed according to the underlying cause.
1. Hyperlipidemia: In patients with elevated blood lipid levels, the blood tends to be more viscous. After meals, blood viscosity increases further, slowing blood flow and leading to insufficient blood supply, ischemia, and hypoxia in the brain, which can result in drowsiness. It is important to maintain a low-salt, low-fat diet. Additionally, lipid-lowering medications such as statins (e.g., simvastatin, atorvastatin) may be used as prescribed by a physician.
2. Cerebral Atherosclerosis: If a patient experiences severe drowsiness not only after meals but also at other times of the day, it may be due to inadequate cerebral blood supply caused by cerebral atherosclerosis. Antiplatelet drugs such as aspirin or clopidogrel may be prescribed by a doctor for treatment.
3. Iron-Deficiency Anemia: A reduction in red blood cells leads to decreased oxygen-carrying capacity in the body, often causing symptoms such as sleepiness and fatigue. Patients should visit a hospital for a complete blood count test. Once diagnosed, treatment may include iron supplements such as ferrous sulfate tablets or ferrous succinate tablets, along with increased intake of iron-rich foods like pork liver and pig blood.
