So, what causes excessive back sweating?

There are two main causes:

Primary hyperhidrosis – a medical condition that causes overactive sweat glands. Although it affects all parts of the body, it’s often localised to specific areas like the back.

Secondary hyperhidrosis – this can be a side effect of medication, a change in hormone levels or a damaged nervous system.

Back sweats brought on by either of these are best dealt with by a doctor or dermatologist. They can recommend proper medical treatment.
