Body feels weak with cold sweats, and the mind is foggy and drowsy.

Body weakness with cold sweats and mental fogginess may be caused by conditions such as upper respiratory tract infection, hypertension, or subarachnoid hemorrhage. These can be treated through medications, surgery, or other methods. Specific analyses are as follows:

1. Upper Respiratory Tract Infection

An upper respiratory tract infection is a common illness caused by pathogens invading the upper respiratory tract, triggering an inflammatory response. This inflammation can lead to increased body temperature and metabolic rate, resulting in symptoms such as dizziness and general weakness. Patients may take medications such as cefuroxime axetil tablets or amoxicillin capsules under medical guidance.

2. Hypertension

Hypertension increases the thickness of blood vessel walls and raises resistance to blood flow, thereby increasing cardiac load and causing tissue hypoxia, which may lead to symptoms including headache and dizziness. Patients may be prescribed medications such as metoprolol tartrate tablets or enalapril maleate tablets under a doctor's supervision.

3. Subarachnoid Hemorrhage

Subarachnoid hemorrhage is a cerebrovascular disease caused by the rupture of a cerebral aneurysm, leading to bleeding into the subarachnoid space. This can trigger cerebral vasospasm, brain edema, and other complications, causing symptoms such as discomfort in the head and cold sweats. Treatment options include ventricular puncture and drainage, or shunt surgery for hydrocephalus.

In addition to the above causes, similar symptoms may also result from viral meningitis, cerebral embolism, or intracranial tumors. It is important to maintain a healthy lifestyle, ensure adequate sleep, avoid excessive fatigue, and manage diet properly to support recovery.
