What are the possible reasons for always feeling drowsy and lacking energy?
Feeling constantly drowsy and lacking energy may be caused by physiological factors or pathological conditions such as anemia or insufficient cerebral blood supply. The specific causes are as follows:
I. Physiological Factors
If a patient has frequent social engagements and a busy work schedule in daily life, leading to reduced sleep duration and inadequate deep sleep, the above-mentioned symptoms may occur. This phenomenon is considered a normal physiological response and can be relieved with proper rest.
II. Pathological Factors
1. Anemia
Anemia refers to a clinical syndrome characterized by a reduction in peripheral red blood cell volume below the lower limit of the normal range, resulting in inadequate oxygen delivery to tissues and organs. Anemia may deprive the brain of sufficient oxygen and energy, thereby causing the aforementioned symptoms. Patients can increase their intake of iron-rich foods such as pork liver and spinach. If necessary, medications such as ferrous gluconate tablets or ferrous fumarate granules may be taken under medical guidance.2. Insufficient Cerebral Blood Supply
Narrowing of cerebral blood vessels or arterial hardening may lead to inadequate blood flow to the brain. When cerebral perfusion is insufficient, patients may experience the symptoms described above. Treatment may include taking medications such as clopidogrel hydrogen sulfate tablets or warfarin sodium tablets as prescribed by a physician.
In addition to the above, other possible causes include hypotension, cervical spondylosis, and fatty liver disease. It is recommended that patients pay attention to adequate rest in daily life and avoid chronic sleep deprivation to prevent worsening of their condition.
