Introduction
Small pits on the nails may be caused by dry weather or inadequate nail nutrition, especially deficiencies in trace elements such as iron and zinc. If there are numerous punctate depressions on the nails along with large red patches, and if these patches flake when scratched, it is important to visit a hospital for evaluation to determine whether the nail pitting is related to psoriasis, which requires prompt and active treatment.
In daily life, nails may exhibit abnormal growth patterns, such as vertical ridges, horizontal grooves, uneven surfaces, or small pits—what causes these tiny depressions on the nails?
What Causes Small Pits on the Nails?
Small pits on the nails may result from dry weather or inadequate nail nutrition—particularly deficiencies in trace elements such as iron and zinc. If numerous pinpoint depressions appear alongside large red plaques on the nails, and if these plaques become scaly when scratched, it is essential to consult a physician for evaluation. Such findings may indicate nail psoriasis, which requires prompt and active treatment.
Small nail pits may also stem from calcium deficiency. Calcium insufficiency can lead to irregular nail texture and horizontal ridges. Patients are advised to undergo calcium supplementation to alleviate symptoms and to increase dietary intake of calcium- and vitamin D–rich foods. Alternatively, protein deficiency may be responsible; insufficient protein intake can cause pitting and perforations in the nails. Patients should consider incorporating soy products, meat, nuts, eggs, and milk into their diet.
Zinc deficiency may also contribute to this condition. Vitamin deficiencies—especially those affecting nail health—can cause softening, layering, whitening, pitting, and vertical ridging of the nails. Patients should undergo testing for trace element levels at a medical facility and supplement accordingly based on laboratory results. During recovery, maintaining local nail hygiene is also important. We hope this information is helpful. Wishing you good health and happiness!
