Introduction
Fatigue usually refers to weakness. Dizziness and fatigue may be caused by lack of sleep, upper respiratory tract infection, iron-deficiency anemia, hypertension, cervical spondylosis, or other conditions. Patients should promptly visit a正规 hospital for proper diagnosis and receive targeted treatment accordingly. In daily diet, it is important to avoid spicy, stimulating, raw, cold, and hard foods, and focus on light, easily digestible meals.
Weakness usually refers to fatigue. Dizziness and fatigue may be caused by lack of sleep, upper respiratory tract infections, iron-deficiency anemia, hypertension, cervical spondylosis, or other conditions. Patients should promptly visit a正规 hospital to determine the underlying cause and receive appropriate treatment. Specific analyses are as follows:
1. Sleep deprivation
Long-term熬夜 or poor sleep quality can lead to sleep deprivation, causing excessive brain fatigue, cerebral blood vessel spasms, and consequently cerebral hypoxia and ischemia, resulting in symptoms such as dizziness and fatigue. It is recommended to ensure adequate sleep, avoid长期熬夜 or overexertion, and maintain scientifically sound daily routines to help alleviate these symptoms.
2. Upper respiratory tract infection
Upper respiratory tract infections are primarily caused by viral infections. Besides symptoms such as coughing, sneezing, and runny nose, severe cases may also trigger systemic symptoms including dizziness, fatigue, and breathing difficulties. Under medical guidance, patients may use medications such as acetaminophen tablets, ibuprofen tablets, or compound licorice tablets for treatment.
3. Iron-deficiency anemia
Iron-deficiency anemia occurs when the body lacks sufficient iron to produce adequate red blood cells, leading to reduced oxygen-carrying capacity. The central nervous system may exhibit signs of hypoxia, such as dizziness and blurred vision, along with symptoms like fatigue and easy tiredness. Patients may take ferrous sulfate tablets, ferrous succinate tablets, or ferrous fumarate tablets as prescribed by a physician.
4. Hypertension
Hypertension refers to blood pressure levels exceeding normal values as blood flows through the vessels, leading to symptoms such as dizziness and general weakness. Prolonged high blood pressure may also contribute to atherosclerosis, further worsening symptoms like dizziness, insomnia, and tinnitus. Under medical supervision, patients may use antihypertensive drugs such as valsartan/hydrochlorothiazide tablets, nifedipine tablets, or spironolactone tablets.
5. Cervical spondylosis
Cervical spondylosis results from compression of neck nerves and blood vessels due to herniated intervertebral discs, neck injuries, bone spurs, or similar causes. Common symptoms include dizziness, headache, nausea, vomiting, neck soreness, and numbness or discomfort in the upper limbs. Patients may take medications such as betahistine mesylate tablets, eperisone hydrochloride tablets, or celecoxib capsules as directed by a doctor.
In daily diet, it is important to avoid spicy, stimulating, raw, cold, or hard foods, and instead focus on light, easily digestible meals. If symptoms persist without improvement, timely medical evaluation and diagnosis are recommended.
