It is possible to evaluate the state of general health by observing the characteristics of the nails, since most serious health problems are capable of altering the process of growth and development of the nails.
Thus, to evaluate health through the nails, the most important is to maintain the nail without any type of enamel, as it is the only way to correctly evaluate all the characteristics of the nail, such as color, shine, shape and texture, for example.
If it is possible to identify changes in the normal characteristics of the nails, it is recommended to consult a dermatologist to diagnose the problem and start the appropriate treatment.
Major nail changes that reveal health problems
1. Yellowish nails
Yellowish nails can indicate various types of problems, from fungal infection, psoriasis, diabetes or cigarette smoke spots, for example, to smokers. Here's how to treat psoriasis in: Treatment for psoriasis.
What to do: It is advised to consult the dermatologist to assess the presence of fungal infection or psoriasis on the nail and initiate appropriate treatment, especially when you are not a smoker.
2. Dry and brittle nails
Dry and brittle nails are those that break or chip very easily and are usually related to natural aging or excess manicure in the hairdressing salon. However, they can also be a sign of vitamin A, B or C deficiency as they are responsible for producing a protein that gives strength to the nails.
What to do: It is recommended to rest the nail and avoid doing a manicure for about 2 weeks. However, if the problem persists, it is important to consult a dermatologist to assess if there is a vitamin deficiency. Get to know some foods with vitamin A: Foods rich in vitamin A.
3. White spots on the nails
White spots on the nails are usually small and difficult to remove, arising mainly from nail bangs or nail injuries such as clapping the nail on the wall or removing cuticles.
What to do: let the nail grow naturally until the white spots disappear. However, if the stain remains the same over several weeks it is advised to consult the dermatologist as it may be a sign of fungal infection.
4. Bluish fingernails
Bluish fingernails are usually a sign of lack of oxygenation of the fingertips and are therefore a normal symptom when in a cold environment, for example. However, if the blue color appears at other times, it may indicate circulatory, respiratory or cardiac problems.
What to do: It is recommended to consult a dermatologist or cardiologist if the problem appears frequently, it takes time to disappear or other symptoms appear. See the symptoms to watch out for: Symptoms of heart disease.
5. Nails with dark lines
Dark lines under the nail are common in people with dark skin, but when they appear suddenly or develop over time, they may signal the growth of a sign underneath the nail and may be one of the first symptoms of skin cancer. Know others in: Signs of skin cancer.
What to do: It is advised to consult a dermatologist immediately if the stain appears suddenly or develops over time, changing color, size or shape.
6. Face-up nails
Upset nails are a sign that the bloodstream is failing to reach the center of the nail properly and may therefore be a symptom of iron deficiency, heart problems or hypothyroidism, for example.
What to do: You should see a dermatologist or general practitioner for a blood test to see if it is a nutritional deficiency that is causing the problem or if there is a thyroid or heart problem.
In addition to these problems, another less frequent change is the appearance of small holes or grooves in the nails that are usually related to nail traumas such as pinning the finger on the door. However, if no nail trauma has occurred, it may also be a sign of diabetes, hormonal changes, excessive stress, or thyroid problems, so consult your dermatologist or general practitioner.
