Nail changes can be considered a true measure of a person's health, body requirements and needs. Some indicate the possibility of certain diseases and others that appear as a result of natural changes.
Healthy nails are usually strong, flexible, smooth, shiny color, and any nail changes - such as white spots, cracks, or deformities - are actually signs of specific diseases, according to the German Focus website.
These changes often occur gradually or suddenly. The site adds that nail changes must be taken seriously, because they actually indicate that the body has serious diseases such as heart, lung, and liver diseases.
The shape of the nails is linked to the state of health and any change in the shape or color of the nail may indicate some health problems. There are even signs that the doctor can diagnose it only by looking at the nails. "Ndr" channel displays nails shapes, colors and their relationship to health status:
White spots on the nails, most of which are harmless air pockets that arise when the nail grows.
Yellow spots in the nails can be caused by contact with cleaning agents or by excessive use of nail dye such as red that penetrates the nail plate.
Light brown color indicates the onset of fungus in the nails, so it is advisable to visit the doctor in this case, because the infection can spread to other nails.
Dark brown near black spots whose shape does not change, possible evidence of black skin cancer (melanoma).
Nail cracks are often associated with arthritis or autoimmune diseases such as psoriasis and circular hair loss, or nail cracks may also be caused by the failure of the nails to get enough blood, according to the German website, "Foret Van". If the shape of the nails changes suddenly and becomes rough, this indicates problems in the heart, liver or lung.
