Hyperkeratosis is associated with density of the outer layer of epidermis so in other words it is connected with the natural reaction of organism. If while maintaining due care of nails cornification is still increased without specific reason, then pathological changes in the skin or connective tissue may take place. In the next stage depositions, corns, warts, crackings, ruptures and inflammations may occur. The feet reflect the functioning of arterial and venous circulatory systems. They show whether it is correct or disturbed. The disorders of above mentioned systems damage vegetative peripheral nervous system of sebaceous and sweat glands. In consequence some layers of the skin will not receive enough fluids and lipids. The dry skin may appear on the whole feet or on its part. Yellow, white and yellow, grey and yellow, brown and grey, dried out epidermis changes into solid and homogeneous texture, but it also may be brittle, cracked and prone to peeling. Parts of the feet which bear the most weight are heels, the regions of proximal joints of toenails, external edges of the sole and distal phalanges (especially in case of fallen transverse metatarsal arch) are exposed to hyperkeratosis.
The causes of hyperkeratosis (excessive cornification) are:
- Fracture andpressure
- Endocrine disruption and vegetative symptoms
- Diabetes, rheumatism, liver and kidney disease
- Inappropriate footwear
- Obesity
- Prolonged time in standing position
- Anatomical feet deformity and inappropriate bone positioning
