The structure of the nail is a good indicator of the general state of health.
You should suspect an infection or fungus if the nail changes color. Sometimes the cause of the color change is nail polish or an allergic reaction. The nail may also turn yellow when the body lacks vitamins or minerals.
In some clinical cases, yellow nails are a symptom of serious diseases such as chronic lung pathologies, lymphatic obstruction, rheumatoid arthritis.
In some clinical cases, despite a repeated course of treatment, your nails remain yellow and this is due to thyroid diseases, psoriasis or diabetes.
To prevent nail discoloration, it is recommended to observe hand hygiene. Use only those beauty salons and spa centers where all sanitary standards are observed. Use nail polish remover only once a week. Always clean the area under your nails - clean the area of your toenails.
To protect yourself from toenail infections, you should always wear new, clean socks and keep your feet in the fresh air.
If your nail does not improve within 10 days to 2 weeks after trying home remedies, see a doctor. See a doctor immediately if you notice a dark line on your nail.
