Just one glance at the fingernails is enough to make a diagnosis, say experts from the American Academy of Dermatology. The nails can identify signs of anemia, problems with the lungs, the presence of fungi.

So, if the nail plate is yellow and laminates, it may be affected by a fungal infection. Also, problems with the liver, lymphatic system or the presence of a pulmonary disease like chronic bronchitis are not excluded, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. Net Dark lines under the nails are associated with an increased risk of skin cancer - melanoma. Experts recommend immediately to contact specialists when detecting lines. But with an abnormal increase in fingertips and bending of the nails, there is likely to be a shortage of oxygen in the bloodstream due to heart and lung diseases (congenital defect, chronic pulmonary infection, cirrhosis of the liver, or infection of the lining of the heart chambers). One of the most common causes is lung cancer.

Cracked or covered with cavities of the nails are often people with psoriasis, chronic dermatitis, focal alopecia or arthritis. And the strips on the nails testify to the experience of the disease, the effect of low temperatures, if a person suffers from Raynaud's disease, the uncontrolled course of diabetes, pneumonia, measles and circulatory system diseases.

Nails in the form of spoons (that is, strongly concave), are associated with trauma, the use of oil solvents, the presence of a syndrome that involves the displacement of the knee cap, deviations in the development of the kidneys and skeleton. Often this syndrome occurs in people with anemia. When most of the nail plate is white, it is worth checking the liver cirrhosis, diabetes, congestive heart failure and malnutrition.
