Introduction
In general, sudden dizziness lasting for several hours without relief may be caused by factors such as lack of sleep, iron-deficiency anemia, or high blood pressure. It can be alleviated under medical guidance through medication and lifestyle improvements. It is recommended to increase daily nutritional intake and consume more foods rich in iron and protein, such as milk, eggs, and similar items.
Generally, sudden dizziness lasting for several hours without relief may be caused by factors such as sleep deprivation, iron-deficiency anemia, or hypertension. Symptoms can be alleviated under medical guidance through medication and lifestyle improvements.
1. Sleep deprivation: Long-term lack of sleep may disrupt the body's blood supply system, slowing blood flow and reducing blood volume, leading to insufficient blood supply and resulting in hypoxia and ischemia. This can cause symptoms such as dizziness, headache, nausea, and vomiting. It is recommended to maintain adequate sleep. For severe cases, medications such as Anshen Bunao Liquid or Bailleimian Capsules may be taken orally as directed by a physician.
2. Iron-deficiency anemia: Iron deficiency reduces blood volume and lowers the number of red blood cells in circulation, decreasing blood oxygen levels, which may lead to persistent dizziness. It is advisable to increase nutritional intake, especially foods rich in iron and protein. Additionally, treatment should include iron supplements such as ferrous sulfate tablets or ferrous succinate tablets, taken as prescribed.
3. Hypertension: Elevated blood pressure can cause cerebral blood vessel spasms, reducing cerebral blood flow and resulting in dizziness. Increased blood pressure may also trigger neurological reflexes that produce abnormal sensations, leading to symptoms such as dizziness and headache. Treatment should follow medical advice, including oral administration of antihypertensive medications such as nifedipine sustained-release tablets or losartan potassium tablets.
