The condition of drowsiness, mental sleepiness, lack of energy and desire to sleep is mostly considered to be caused by unstable blood sugar or high blood lipids. If the test belongs to low blood sugar, it is recommended to take a small number of meals to change the blood sugar situation. If the test is high blood lipids, it is recommended to take simvastatin drugs under the guidance of a doctor to maintain the treatment, so that it will return to normal. There are also people who are often drowsy because they stay up late at night, rest less, and are mentally tense, and generally this kind of work will bring patients drowsy. Usually pay more attention to rest, eat more protein-rich food, and pay attention to eat more fresh vegetables and fruits to see if there is any improvement.
