Sweaty Conditions

Eccrine glands are the major sweat glands of the human body, found in virtually all skin, with the highest density in palms and soles, then on the head, but much less on the trunk and the extremities.

Apocrine glands are found in the armpit, around the nipples, perineum (between the anus and genitals), in the ear and in the eyelids.

Anhidrosis – [an: without + hidros: sweat] Characterized by an absence of perspiration.

Bromhidrosis – [bromos: stench + hidros: sweat] Characterized by abnormal or offensive body odour, to a large extent determined by apocrine gland secretion. The condition is further aggravated by poor hygiene or underlying disorders promoting bacterial overgrowth, including diabetes and obesity.

Cyanhidrosis [kyanos: dark blue + hidros: sweat] - Characterized by bluish perspiration.

Dyshidrosis - [dus: bad + hidros: sweat] Dyshidrosis is a misnomer, because it has virtually nothing to do with sweat.

Hemihidrosis - [hemi: half + hidros: sweat] Characterized by sweating of symmetrical areas of the torso[2].

Hyperhidrosis – [huper: over + hidros: sweat] Characterized by increased sweat secretion.
- Acrohyperhidrosis - Characterized by increased sweat secretion of the hands and feet.
- Axillary Hyperhidrosis - Characterized by increased sweat secretion in your armpits.
- Cranofacial Hyperhidrosis - Characterized by increased sweat secretion on your face, head and scalp.
- Facial Hyperhidrosis - Characterized by increased sweat secretion on your scalp or face.
- Gluteal Hyperhidrosis - Characterized by increased sweat on your backside, lower back or buttocks.
- Inguinal Hyperhidrosis - Characterized by increased sweat secreton in your groin.

Melanidrosis - An obsolete term for Melanephidrosis.

Menhidrosis [men: month + hidros: sweat] An obsolete term for vicarious menstruation via sweat glands at the time of menses. At least some cases of which may have been due to endometriosis.

Urohidrosis - [ouron: urine + hidros: sweat] is the habit in some birds of defecating onto the scaly portions of the legs as a cooling mechanism, using evaporative cooling of the fluids. Several species of storks and New World vultures exhibit this behaviour. The term is also used to describe the analogous behaviour in seals that cool themselves while basking by urinating on their hind flippers.
