Diaphoresis = sudden, profuse sweating without obvious trigger (heat, exertion). It often signals an underlying issue.
Medical Causes
- Hormonal: Menopause, hyperthyroidism, diabetes (hypoglycemia), pheochromocytoma, carcinoid.
- Cardiac: MI, angina, heart failure—often with chest pain, dyspnea.
- Infectious: TB, endocarditis, HIV, malaria, sepsis.
- Neurological: Autonomic dysreflexia (SCI), Parkinson's, stroke, syringomyelia.
- Malignancy: Lymphoma, leukemia, solid tumors.
- Medications: Antidepressants (SSRIs/SNRIs), antipsychotics, opioids, steroids, some BP meds.
Other Triggers
- Stress, anxiety, panic attacks
- Spicy food, alcohol, caffeine
- Withdrawal (alcohol, opioids, benzos)
Red Flags—Seek Emergency Care
- Chest pain, shortness of breath, dizziness, nausea/vomiting
- Profuse sweating + hemodynamic instability
- New-onset unexplained diaphoresis
Self-Care (Non-Urgent)
- Hydrate, cool environment, loose clothing
- Identify/avoid triggers (spice, caffeine, stress)
