The nails, both of the hands and feet, protect the fibers of the toes. They are consumed, according to the National Library of Medicine, by a layer of protein called keratin, which is also found in hair and skin.
The state of these can be a sign of the general state of health of the organism, so it is necessary to pay attention if any changes appear. According to the aforementioned portal of the doctor, healthy nails are usually smooth and uniform in color. On the other hand, different types of nail colors and growth changes indicate lung, heart, kidney and liver diseases, diabetes and anemia. As for the white spots and vertical ridges, there is no need to worry that they are harmless.
How to detect diseases by your fingernails
The College of Official Pharmacists of Madrid (COFM) shows the most frequent colors and changes that the nails can acquire in the case of pain of some kind of disease or lack of nutrients.
1. Brittle nails
Generally, weak and brittle nails result from a disordered diet, in which there are not enough vitamins, proteins or iron. But the most important thing is to control the food and include in it the amount of fruits and vegetables. It can also be from aging or a fungal infection, in which case it should be seen by a specialist.
2. White nails
White spots that appear in the middle of the nail are not a concern. However, the parallel white lines that can be extended across the entire width of the fingernails indicate, as COFM explains, a low level of protein in the blood, which is due to liver, kidney or heart failure, diabetes, hyperthyroidism and reduced status. .
3. Yellow fingernails
Pitch and hydrogen are the most common causes of yellow nails. Despite this, it can also indicate health problems such as liver or kidney disease and lack of nutrients such as vitamins A and B, iron, zinc, calcium or protein. In addition, the consumption of certain medications and aging can be the cause of this color in the nails.
4. Blue or purple nails
This color will indicate that you have poor blood circulation. Above all, pay attention to darker colors, as they may indicate a heart problem.
5. Brown nails
COFM explains that this is due to the exposure of some financial institutions, such as nail polish. This type of spot most often appears on the nails. Also, in many cases this color can indicate that you have a fungal infection, so you will have to go to a dermatologist to indicate the most appropriate treatment, which is usually based on antifungal lotions or creams.
