Causes of Hyperhidrosis
The cause of hyperhidrosis is based upon the origin of the stimulus causing the sweating response.
These triggers may come from the;
Hypothalamic Area (area of the brain that controls temperature, hunger and thirst)
- Emotional response
Medullary Area (area of the brain that controls involuntary functions, like breathing)
- Systemic diseases - infections, etc
- Chiari malformations (malformation of the brain) can cause localized hyperhidrosis
- Infarction (stroke)
- Syringomyelia is a disease of the spinal cord that can also cause rare hyperhidrosis,
- Spinal cord mass lesions (such as tumors) can cause it
Axon reflex: (local nerve reflexes)
- Hyperhidrosis can occur bordering painful skin lesions such as venous ulcers
Endocrine System: (Hormonal)
- Post-sympathectomy (surgical interruption of nerves)
- Ross syndrome
Primary or Idiopathic Hyperhidrosis - Cause unknown, usually appears in localized areas:
- Hyperthyroidism - excessive activity of the thyroid
- Hyperpituitarism - excessive secretion of the pituitary gland
- Increased release of catecholamine (shock, fight-or flight response)
- Axilla - underarms
- Palms of hand
- Soles of feet
Common sites of excessive sweating and their impact on Quality of Life (QOL)
Palms and Plantar (soles of feet)
- Sweaty palms and feet have a higher QOL impact than axillary sweating
Face and scalp
- QOL impact can be significant - embarrassing, sweat stains, odor
- Highly visible, highest QOL impact (more than hands & feet, and more than axillary)
- Generalized (QOL impact is higher than isolated localized hyperhidrosis)
