Generalized weakness, cold sweats, and persistent fatigue—what could be the cause, and what should I do?

Generalized weakness, cold sweats, and drowsiness may be related to autonomic nervous system dysfunction, hypoglycemia, upper respiratory tract infections, and other causes. These symptoms can be managed through daily care, medication, and other interventions. Specific analyses are as follows:

1. Autonomic Nervous System Dysfunction

If the autonomic nervous system becomes dysregulated, it may affect the respiratory and cardiovascular systems, leading to symptoms such as chest tightness, shortness of breath, sweating, and generalized skin warmth. Patients should maintain a positive mood and, under medical guidance, take neurotrophic medications such as oryzanol tablets and vitamin B1 tablets.

2. Hypoglycemia

During hypoglycemia, the body does not receive sufficient energy, resulting in symptoms such as generalized weakness and fatigue. Patients may take oral glucose solution, furosemide tablets, or other medications under a doctor's supervision.

3. Upper Respiratory Tract Infection

An upper respiratory tract infection is a type of respiratory illness. During the course of the disease, the body consumes significant energy to fight pathogens, which often leads to systemic fatigue. Patients may follow medical advice to take medications such as compound paracetamol and amantadine hydrochloride capsules or phenylephrine, dextromethorphan, and acetaminophen tablets.

In addition to the common causes listed above, these symptoms may also be associated with anemia, hypotension, and other conditions. Patients should seek medical evaluation at a hospital to determine the underlying cause and receive standardized treatment.
