Half and half nails, also known as Lindsay’s nails, is a condition where the nails appear to have two different colors or characteristics. One half of the nail (usually the proximal half) is white or pale, while the other half is pink, red, or brown.
This condition can be caused by various underlying factors, including:
- Renal (kidney) disease: Half and half nails are commonly associated with chronic renal failure. The changes in nail coloration are thought to be a result of abnormal blood supply and the accumulation of waste products in the body.
- Liver disease: Liver dysfunction can also cause half and half nails. It is believed that the liver’s decreased ability to properly metabolize chemicals and toxins may contribute to the nail color changes.
- Malnutrition: Nutritional deficiencies, particularly of protein, iron, and vitamins, can affect nail health and lead to the development of half and half nails.
- Heart disease: In some cases, half and half nails can be linked to certain heart conditions, including congestive heart failure and endocarditis.
- Other potential causes: Half and half nails have also been associated with systemic diseases like hyperthyroidism, HIV infection, diabetes, and systemic lupus erythematosus.
It is important to consult a healthcare professional if you notice any changes in your nails, including the development of half and half nails. They can evaluate your symptoms, perform necessary tests, and help identify the underlying cause.« Back to Glossary Index
