what do clubbed fingernails indicate
The visual appearance of the fingernails and toenails may suggest an underlying systemic disease. Clubbing of the nails often suggests pulmonary disease or inflammatory bowel disease. Koilonychia, or âspoon-shapedâ nails, may stimulate a work-up for hemochromatosis or anemia. In the absence of trauma or psoriasis, onycholysis should prompt a search for symptoms of hyperthyroidism.
