What causes a feeling of dizziness when standing, body lightness, and limb weakness, and what should be done about it?

Feeling light-headed, weak in the limbs, and dizzy when standing may be caused by physiological factors, or by pathological conditions such as anemia or insufficient cerebral blood supply. Treatment can be achieved through general management or medication. Specific details are as follows:

I. Physiological Factors

If excessive workloads or high mental stress lead to severe sleep deprivation, symptoms such as physical fatigue, dizziness, and lethargy may occur. It is important to get adequate rest and avoid overexertion.

II. Pathological Factors

1. Anemia

Anemia is a condition characterized by a reduced volume of red blood cells in the peripheral blood, which decreases the body's ability to carry oxygen, leading to weakness in the limbs. Treatment may include medications such as ferrous succinate tablets or Shengxue Ning tablets, taken as directed by a physician.

2. Insufficient Cerebral Blood Supply

Conditions such as hyperlipidemia or thrombocytosis can increase blood viscosity and slow blood flow, resulting in inadequate blood supply to the brain, causing symptoms like headache and nausea. Medications such as simvastatin tablets or rosuvastatin calcium tablets may be prescribed by a doctor for treatment.

In addition to the above causes, dizziness and weakness could also result from cerebral hypoxia, cerebral hemorrhage, or cerebral infarction. Regular, moderate physical exercise can help improve immune function.
