(HealthDay News)-- Becoming drenched with sweat during an intense workout is to be expected. But what if you constantly sweat, even without exertion?

Excessive sweating, especially when accompanied by other symptoms, may signal that you should visit your doctor. The ADAM Encyclopedia cites these examples:

• Sweating heavily for an extended period without an identifiable cause.
• Feeling pressure or pain in the chest, along with sweating.
• Losing weight.
• Sweating that usually happens while you sleep.
• Any of these symptoms accompanied by difficulty breathing or a very fast, pounding heartbeat.
