Over 80% of patients with severe liver disease, specifically cirrhosis, have been found to have Terry's nails, indicating a strong link to systemic illness rather than a direct nutritional cause. This distinctive nail appearance, with a ground-glass whiteness and a narrow pink or brown tip, is a crucial diagnostic clue for doctors.

According to the National Institutes of Health, iron deficiency is the most common nutritional cause of koilonychia, a condition where your nails become thin, brittle, and shaped like a spoon. This specific type of nail curling is often a direct result of inadequate iron stores in the body, which can affect the protein structure of the nail plate. However, iron deficiency is not the only cause, as other nutrient shortfalls and systemic diseases can also lead to changes in nail curvature.

In rare cases, onycholysis, or the painless separation of the nail plate from its bed, indicates an underlying systemic issue like iron deficiency anemia. Recognizing this less common cause is vital for proper diagnosis and treatment, as many people assume the issue is purely local or cosmetic.

Trauma is the most common cause of splinter hemorrhages. This fact often surprises those who suspect a nutritional link. Many people ask, "Can low iron cause splinter hemorrhages?" The direct connection is not what you might think, as iron deficiency typically manifests with different nail symptoms.

Contrary to a common misconception, fingernails that curl down at the tips are not caused by a vitamin deficiency but are instead often a sign of underlying systemic health conditions. This downward curvature is medically known as "clubbing," a phenomenon distinct from other nutrient-related nail issues, such as spoon-shaped nails, which can result from iron deficiency.
