Why does my head hurt in waves when I stand up after sitting for a long time, and what should I do about it?

Headaches that occur in episodes when standing up after sitting for a long time may be caused by physiological factors, or by pathological conditions such as stroke or cerebral ischemia. Patients can receive treatment through general management or medication. Specific details are as follows:

I. Physiological Factors

Sitting for prolonged periods may slow blood circulation. Suddenly standing up can then lead to dizziness. Usually, no special treatment is required; it is recommended to avoid rising too quickly.

II. Pathological Factors

1. Stroke

Stroke occurs due to sudden rupture of blood vessels in the brain or blockage preventing blood flow into the brain, resulting in brain tissue damage. Common symptoms include dizziness, nausea, and vomiting. Patients may take medications such as Yangxue Qingnao Granules or Yangxue Qingnao Oral Liquid as directed by a physician.

2. Cerebral Ischemia

Narrowing of cerebral blood vessels leads to insufficient blood supply to the brain, potentially causing neurological dysfunction and symptoms such as headache and nausea. Patients may take medications like enteric-coated aspirin tablets or rivaroxaban tablets under medical guidance.

In addition to the above causes, such headaches could also result from conditions such as cerebral infarction or brain tumors. It is recommended that patients seek timely medical evaluation at a qualified hospital upon experiencing these symptoms. Regular physical exercise may also help improve immune function.
