Introduction
Malnutrition is generally caused by insufficient intake or imbalanced proportions of nutrients. Long-term nutritional imbalance, especially deficiency in key nutrients such as iron and vitamins, may lead to abnormal nail growth, resulting in spoon-shaped nails (koilonychia). It may be accompanied by symptoms such as diarrhea and weight loss. Patients can follow medical advice to take medications such as compound vitamin B tablets, vitamin C effervescent tablets, and oral zinc sulfate solution for treatment.
Under normal circumstances, spoon-shaped fingers (koilonychia) may be caused by genetic factors, changes during growth and development, malnutrition, onychomycosis, iron deficiency anemia, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analysis is as follows:
1. Genetic Factors
In some families, spoon-shaped fingers may have a hereditary tendency and are associated with specific gene variations. If family members exhibit symptoms of spoon-shaped fingers, offspring may also have a higher likelihood of developing this condition. Spoon-shaped fingers caused by genetic factors usually do not require special treatment unless they interfere with daily life or are accompanied by other health issues.
2. Changes During Growth and Development
During the growth and development period, the nail bed and bones grow rapidly. Sometimes, the rate of nail growth fails to keep up with bone growth, which may lead to inward indentation of the nail plate, resulting in spoon-shaped fingers. In most cases, spoon-shaped fingers resolve naturally once growth and development are complete.
3. Malnutrition
Malnutrition is generally caused by insufficient intake or imbalance of nutrients. Long-term nutritional imbalances, especially deficiencies in critical nutrients such as iron and vitamins, can lead to abnormal nail growth and the development of spoon-shaped fingers. This may be accompanied by symptoms such as diarrhea and weight loss. Patients may take medications such as compound vitamin B tablets, vitamin C effervescent tablets, and oral zinc sulfate solution as directed by a physician.
4. Onychomycosis
Onychomycosis is usually caused by fungal infection, which may also alter the shape of the nails, including causing spoon-shaped fingers. Common symptoms include nail thickening, discoloration, and shedding. Treatment typically involves antifungal medications such as itraconazole capsules, terbinafine hydrochloride tablets, and ciclopirox olamine cream, used according to a doctor's recommendations.
5. Iron Deficiency Anemia
Iron deficiency anemia is usually caused by reduced hemoglobin synthesis. Decreased hemoglobin reduces the blood’s oxygen-carrying capacity, thereby affecting normal nail growth and metabolism, leading to spoon-shaped fingers. Symptoms may include pallor, fatigue, and dizziness. Under medical supervision, patients may take medications such as compound ferrous sulfate granules, dextran iron tablets, or ferrous fumarate tablets.
It is recommended to maintain healthy lifestyle habits, balance work and rest, and avoid excessive fatigue to promote overall health.
