Typical regions of excessive sweating include the hand palms, underarms, the sole of the foot, and sometimes groin, face, and scalp. Indeed, profuse sweating is present mostly in the underarms, followed by the feet, palms and facial region. [9] Evidence demonstrates that a positive family history is also present (see the Genetics part). [10]
According to Henry Gray's estimates, the palm has around 370 sweat glands per cm 2; the back of the hand has 200 per cm 2; the forehead has 175 per cm 2; the breast, abdomen, and forearm have 155 per cm 2; and the back and legs have 60–80 per cm 2. [2] In the finger pads, sweat glands pores are somewhat irregularly spaced on the epidermal ridges.
Hands, feet, armpits, groin, and the facial area are among the most active regions of perspiration due to the high number of sweat glands (eccrine glands in particular) in these areas. When excessive sweating is localized (e.g. palms, soles, face, underarms, scalp) it is referred to as primary hyperhidrosis or focal hyperhidrosis.
Palmoplantar hyperhidrosis is excessive sweating localized to the palms of the hands and soles of the feet. It is a form of focal hyperhidrosis in that the excessive sweating is limited to a specific region of the body. As with other types of focal hyperhidrosis (e.g. axillary and craniofacial) the sweating tends to worsen during warm weather. [1]
Or cold hands that come with other symptoms, such as joint pain, a new rash, weight loss, night sweats (as seen in connective tissue/autoimmune diseases), pallor, weakness, shortness of breath ...
Acquired idiopathic generalized anhidrosis appears to have a variety of etiologies. Theoretically, dysfunction or degeneration of cholinergic sympathetic nerve fibers involved in sweating (sudomotor neuropathy), dysfunction of acetylcholine receptors and/or cholinergic signals (idiopathic pure sudomotor failure may fall under this category), and primary failures of the sweat glands with ...
Decreased sweating, while less common, can occur with those who have diabetic neuropathy, which damages nerves and interferes with the ability of the sweat glands to function.
Treatments for hyperhidrosis include antiperspirants, iontophoresis, and surgical removal of sweat glands. In severe cases, botulinum toxin injections or surgical cutting of nerves that stimulate the excessive sweating ( endoscopic thoracic sympathectomy ) may be an option.
