Spots on the nails: causes, diagnosis, and treatment
About the symptom
Spots on the nails are an unusual manifestation that may signal various health conditions. These changes can vary in color, shape, and size, and generally indicate the presence of certain problems in the body. The most common types of spots are white, yellow, or brown dots that can appear on both fingernails and toenails. They are often ignored, as people assume they are just a cosmetic defect; however, they frequently become the first sign of more serious illnesses.
Often, spots on the nails may arise due to damage to the nail plate, infectious diseases such as fungus, or systemic diseases including diabetes and liver disorders. Some spots may also result from a deficiency of vitamins and minerals in the body, such as zinc, calcium, or vitamin B12. If you notice spots on your nails, it is important to pay attention to them and consult a doctor for diagnosis and treatment if necessary, as identifying the cause is a key step in maintaining the health of the nails and the body as a whole.
Diseases
Spots on the nails can signal various diseases, both serious and less dangerous. Nails serve a protective function, and any changes in their structure and color may indicate internal problems in the body. Most often, spots arise due to nutritional deficiencies, as well as due to various diseases, including infectious and autoimmune conditions. It is important to pay attention to such changes and consult a doctor to determine the cause.
Some of the most common diseases associated with the appearance of spots on the nails include:
- Fungal infections: Mycoses can cause white or yellow spots on the nails, as well as thickening and brittleness.
- Psoriasis: This chronic skin condition can also manifest as spots on the nails, often with characteristic indentations.
- eczema: Inflammatory skin processes can cause changes in the nails, including the appearance of spots.
- Anemia: Iron deficiency in the body can lead to changes in nail color and structure.
- Systemic diseases: Such as diabetes and kidney diseases can also cause changes in the condition of the nails.
Diagnosis
Effective diagnosis is an important step in identifying the causes of the appearance of spots on the nails. The initial appointment with a dermatologist includes taking a medical history, where the doctor asks questions about when the spots appeared, their size, color, and texture. The presence of other symptoms such as pain, itching, or swelling is also significant. An important aspect of the diagnosis is studying the disease history, both from the patient and their relatives. This helps identify possible genetic predispositions to certain diseases.
After collecting the information, the doctor may order additional diagnostic tests. These procedures help exclude serious diseases and better understand the nature of the changes in the nails. Based on the results obtained, the doctor will be able to recommend appropriate treatment and adjust the patient’s lifestyle to prevent further worsening of the condition.

Depending on the cause of the spots, treatment approaches may vary. For example, if the spots are caused by a fungus, antifungal medications are prescribed in both oral and topical forms.
