Sudden excessive sweating can be caused by a variety of factors including an underlying medical condition, medication side effects, or hormonal changes. Conditions like hyperthyroidism (overactive thyroid), diabetes (low blood sugar), infections, fever, menopause, and certain cancers can trigger sudden sweating. It may also be related to hyperhidrosis, where sweat glands overwork without typical triggers like heat or exercise. Stress and strong emotions can also cause sudden sweating. If the sweating is severe or accompanied by other symptoms like chest pain, dizziness, or fever, it is important to seek medical evaluation promptly to rule out serious causes such as a heart attack or infections.
Key reasons for sudden excessive sweating include:
- Medical conditions (e.g., hyperthyroidism, diabetes, infections, cancers)
- Medication side effects (e.g., antidepressants, beta blockers)
- Hormonal changes (menopause, pregnancy)
- Emotional triggers (stress, anxiety)
- Primary hyperhidrosis (inherited overactive sweat glands)
If experiencing this symptom suddenly and intensely, consulting a healthcare provider is recommended for diagnosis and appropriate treatment.
