Long-term medical research has proven that the condition of the nails can be used to diagnose various diseases in the early stages, long before any symptoms appear. For several centuries, Chinese doctors have accumulated knowledge about methods of identifying diseases by the shape and appearance of human nails.
Examine the nail sockets carefully. In active smokers, as well as in people with pulmonary diseases, they will be thin and small. If the hole is missing on the nail of the ring finger, this means possible problems with the metabolism and the lymphatic system. If there are no holes on all the nails of the fingers of the hand, this indicates the likelihood of a lack of vitamin B12, possible problems with the thyroid gland and disorders of the circulatory system. The bluish color of the wells is a sign of liver problems.
Pay attention to the color of your nail plate. A sign of good health is a delicate pink nail. A bright red color is a possible sign of erythremia. If the color is yellow, it is necessary to check the condition of the liver. The white-blue color of the nail plate is a reason to be examined by a gastroenterologist and a neuropathologist, bluish-purple signals the likelihood of congenital heart defects. If your nail plates are gray, it can mean an attack of malaria, black - diabetic gangrene or thrombosis of the brachial artery.
See if there are any stains on your nails. Small white spots can be associated with a malfunction of the central nervous system, and yellow spots can serve as a sign of a malfunction in the functioning of the brain. A bluish tint indicates cardiovascular pathology. Too pale nails are associated with anemia, lack of iron, vitamins and minerals. If the adrenal cortex is affected, the nail plates may be whitish, and with cirrhosis of the liver, milky white. A black spot indicates a subungual hematoma.
Note that the white dots on the ring finger nail may indicate calcium deposition in the kidneys. If there are white specks on the index finger, this indicates a possible accumulation of calcium in the lungs. The presence of brown or dark yellow stains on the nails is the first sign of a fungal disease, and they can also be the result of prolonged use of antibiotics.
In case you notice grooves on the nail plates, be aware that they are mainly signs of previous infectious diseases. Peeling nails, as a rule, indicate diseases of the endocrine system, bulging and thick ones - about malfunctions in the lungs. Psoriasis, or inflammatory joint disease, can contribute to the appearance of multiple dimples in the nails. Lack of iron in the body can lead to deep and concave nail plates.
Remember that the diagnosis of diseases based on the condition of the nails does not give one hundred percent confidence in the presence of these diseases. Only an experienced doctor can make the correct diagnosis and prescribe treatment.
