What to do if the toenails turn purple and black

In fact, we can understand our own health problems by whether the toenails are purple or black, because sometimes toenails can also reflect a person's health status. For example, blackening of nails may be caused by some infection problems. If you suffer from myocarditis, some heart diseases will also have these related symptoms. Therefore, we can use this to determine the correct treatment.

1. Blackening of the nails and broken spots under the nails indicate infection-induced myocarditis (serious heart infection), other heart diseases, and abnormal nail bleeding.

2. Brittle nails may indicate iron deficiency, thyroid problems, impaired kidney function, or blood circulation problems.

3. Brittle, soft and easily worn nails indicate a lack of nutrition and may indicate hyperthyroidism.

4. Black nails and/or thin, flat, spoon-shaped nails are signs of vitamin B12 deficiency or anemia. (Nails may also turn black or gray if hands come into contact with detergents or allergens).

5. Dark blue nails indicate lung obstruction, such as asthma or emphysema.

6. Inward-pointing nail tips indicate abnormalities in the heart, liver, or respiratory system.

7. In addition to local fungal infections, green nails can also indicate bacterial infections in the body.

8. Half-white nails with black spots on the fingertips may indicate kidney disease.

9. The appearance of isolated green streaks on the nail bed, especially on fair skin, is a sign of skin cancer.

10. Beaded nails (uneven surface) are a sign of rheumatoid arthritis.

11. Nails that extend to the fingertips and curve downward are a sign of lung damage, such as emphysema and asbestosis.

12. Easy to break, crack, and peel off indicates malnutrition and lack of hydrochloric acid and protein. Minerals are also extremely deficient at this time.

13. A bulge at the base of the nail with a very small white part indicates respiratory diseases such as emphysema or chronic bronchitis. This symptom may be hereditary.

14. Separation of the nail from the nail bed suggests thyroid disease or localized infection. It may also be due to excessive exposure to chemicals, such as frequent manicures, frequent soaking of nails in water or contact with chemicals.
