Terrys Nails, Muehrcke’s Nails
The nail will look mostly white and grainy with a pink or perhaps red strip at the top because of an increase in connective tissue and a decrease in blood supply in the nail bed. This change in nail health can be found in 80 percent of patients with liver cirrhosis, as well as in patients with congestive heart failure, hyperthyroidism, malnutrition, diabetes, or HIV.
Abnormal blood flood in the nail bed will make the nails appear as if they have horizontal (often paired) white lines, most often in the second, third, and fourth fingers. The lines disappear if the nail is pressed and blood is squeezed out of the nail bed blood vessels. Because this problem occurs in the nail bed, it will not progress up as the nail grows. Problems associated with this are hypoalbuminemia, liver disease, malnutrition, and nephrotic syndrome; it is also a side effect of chemotherapy.
