Excessive sweating or hyperhidrosis may not appear serious, but it’s also a sign of Parkinson’s disorder. Most people with hyperhidrosis, usually sweat too much on their hands, the bottom of their feet, or their body’s upper portions. Some even say that they sweat so much at night that they have trouble getting a good night’s sleep. 

This issue can result not only from Parkinson’s itself but also the medications you’re taking to treat it. Your doctor may ease the symptom if the latter is the case by adjusting the dosage of your medicine. Meanwhile, hypohidrosis or anhidrosis is the exact opposite. This condition causes a lack of sweating. Similar to hyperhidrosis, the cause of the symptom may either be your medication or the disease itself.
