What causes hyperhidrosis?
Primary hyperhidrosis, which often begins in childhood, is caused by genetics. Secondary hyperhidrosis, which means it’s been caused by another condition, can occur for any number of reasons.
It can happen because of anxiety but it can also be caused by endocrine or metabolic conditions, infections or heart failure. Excessive drinking or drug use can also be a contributing factor.
What are the symptoms of hyperhidrosis?
The main symptom of hyperhidrosis is excessive sweating that happens at times other than when you would naturally sweat. Your sympathetic nervous system sends a signal to your brain telling it to release sweat from glands when it gets too hot, whether that be due to warm weather or carrying out exercise. It acts a bit like your body’s own thermostat.
In someone with hyperhidrosis, this same messaging occurs, but at times when there’s no real reason for you to sweat or for the body to cool down.
Can hyperhidrosis lead to other problems?
On its own hyperhidrosis isn’t a dangerous condition, although it can be frustrating to live with. However, in some cases, it can be a sign of other health conditions or illnesses that might require medical attention or a visit to your doctor to make sure all is well.
