What if black spots grow under the nails?

The inside of the nails is usually not much different from our skin color. If small black dots appear, you should pay attention. The nail area can reflect the physical condition. The appearance of small black spots may mean that the body is infected with myocarditis and other diseases, so it needs to be diagnosed in time.

What are the black spots on nails?

1. Blackening of the nails and broken spots under the nails indicate infection-induced myocarditis (severe heart infection), other heart diseases, or bleeding disorders.

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

3. Half-white nails and black spots on the fingertips may indicate kidney disease.

Why are nails brittle and fragile?

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

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

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