Why Do I Feel Lightheaded All Over?

Feeling lightheaded may be caused by various reasons such as colds, hyponatremia, hypokalemia, non-infectious inflammation, tuberculosis, rheumatic diseases, and others. Here are some possible explanations:

1.1. During the early stages of a cold, the body is often attacked by bacteria, viruses, fungi, and atypical pathogens. This triggers the production of immune complexes, which can lead to severe bodily reactions and the release of inflammatory factors such as leukotrienes and histamines. These inflammatory factors can cause a person to feel lightheaded.

1.2. Disorders of ions in the body, particularly hyponatremia and hypokalemia, can also lead to feelings of weakness, fatigue, and lightheadedness.

1.3. Specific reactions to non-infectious inflammation, such as plant nerve dysfunction, immune tissue diseases, and connective tissue diseases, can also manifest as symptoms of lightheadedness.

1.4. Other common causes of feeling lightheaded include tuberculosis, rheumatic diseases, severe anemia, HIV/AIDS, and tumors.

2.1. Anticold medications are typically compound formulations containing multiple ingredients. Common examples include Sudafed, Cold Relief, Contac, DayQuil/NyQuil, Compound Paracetamol and Amantadine Hydrochloride Tablets, Ganmaokang, and Quick Relief. These medications are not recommended for pregnant women, especially during the first four weeks of pregnancy, as they are primarily symptomatic treatments and may not be safe for use during pregnancy.

2.2. Antiviral drugs can have adverse effects on the fetus and should be avoided by pregnant women. If they are necessary, they should be prescribed and used under the guidance of a doctor.

2.3. If a cold is accompanied by high fever, it may indicate a more serious condition and prompt medical attention should be sought. Anti-inflammatory drugs such as indomethacin are contraindicated for pregnant women, and aspirin should also be avoided.

2.4. Antibiotics should not be used for colds in pregnant women unless there is clear evidence of bacterial infection, such as tonsillitis, hypertension, coughing up yellow mucus, or thick nasal discharge. Antibiotics can pass through the placenta and pose a 20%-40% risk of harm to the fetus. Safe antibiotics should be selected under the guidance of a doctor.

2.5. Cough and expectorant medications are generally considered safe, but cough medications containing iodine should be avoided by pregnant women.
