Introduction

A head CT scan showed no abnormalities, but dizziness may still be caused by physiological factors or pathological conditions such as anemia or hypertension. Treatment may include general management and medication. If the patient frequently suffers from insufficient sleep or significant emotional fluctuations, this may affect brain function and lead to symptoms such as dizziness and headache. It is important to get adequate rest and avoid prolonged熬夜 (staying up late).

Normal head CT results do not rule out dizziness, which may be caused by physiological factors or pathological conditions such as anemia or hypertension. Treatment may involve general management and medication. Specific causes are as follows:

I. Physiological Factors

If a patient frequently experiences insufficient sleep or significant emotional fluctuations, this may affect brain function and lead to symptoms such as dizziness and headache. It is important to get adequate rest and avoid prolonged熬夜 (staying up late).

II. Pathological Factors

1. Anemia

Anemia is mainly associated with inadequate red blood cell production, excessive red blood cell destruction, or blood loss. This leads to ischemia and hypoxia in vital tissues and organs, resulting in dizziness. Treatment may include medications such as succinic acid ferrous tablets or iron dextran dispersible tablets, taken as directed by a physician.

2. Hypertension

Hypertension refers to blood pressure against the vessel walls being higher than normal. It may increase intracranial perfusion pressure, causing paroxysmal headaches, nausea, and other symptoms. It typically does not cause damage detectable by CT scans, so normal imaging results are common. Treatment may include antihypertensive medications such as sulfonate amlodipine tablets or felodipine sustained-release tablets, taken as prescribed.

In addition to the above causes, dizziness could also result from conditions such as cerebral hemorrhage or cerebral infarction. Ensure regular ventilation by opening windows frequently to maintain good indoor air circulation.

Will having a cold affect the results of a COVID-19 nucleic acid test?

A cold generally does not directly affect the results of a nucleic acid test for COVID-19. However, since the body is relatively weak during a cold, it's important to stay warm before and after testing to avoid worsening symptoms due to exposure to cold. Avoid smoking, drinking alcohol, or chewing gum within half an hour before the test to minimize irritation to the throat. During sample collection, cooperate with healthcare personnel by tilting your head backward and try to stay relaxed to reduce discomfort.

Is there an effective treatment for avascular necrosis of the femoral head, and can conservative treatment be an option?

Avascular necrosis of the femoral head can be managed with either conservative treatment or surgical options, depending on the severity of the condition. Conservative treatment tends to be more effective in early-stage patients, while those in moderate to advanced stages often require surgical intervention. Individuals experiencing symptoms such as hip pain and limited mobility should seek timely evaluation and treatment at a reputable hospital's orthopedic department. Conservative treatment is suitable for the early stages of necrosis and primarily focuses on reducing weight-bearing on the femoral head.

Can avascular necrosis of the femoral head heal on its own?

Avascular necrosis of the femoral head cannot heal on its own. Its core pathology involves impaired or interrupted blood supply to the femoral head, leading to osteocyte death. The necrotic tissue cannot repair itself and will progressively worsen, potentially resulting in femoral head collapse and joint dysfunction. When symptoms such as hip pain and restricted movement occur, prompt medical evaluation at a reputable hospital's orthopedic or joint surgery department is necessary.

How to manage avascular necrosis of the femoral head in daily life

Daily care for avascular necrosis of the femoral head involves weight control, avoiding weight-bearing activities, engaging in appropriate exercise, taking medications as prescribed, and maintaining a balanced diet. If symptoms such as persistent hip joint pain or limited mobility occur, prompt medical evaluation is necessary. Excess body weight increases pressure on the femoral head, accelerating bone damage; therefore, maintaining a healthy weight through proper diet and exercise is essential.
