My pints of blueberries donât weight 16 ounces!â. A dry pint is not a measurement of weightâit is volume, as in cubic inches. (A liquid pint, as in a pint of cream, gives you fluid ounces). A pint of feathers takes up the same amount of space as a dry pint of marbles, but they certainly donât weight the same!
1 Liver disease can damage nails. 2  Thyroid diseases such as hyperthyroidism or hypothyroidism may cause brittle nails or splitting of the nail bed from the nail plate (onycholysis). 3  Severe illness or surgery may cause horizontal depressions in the nails (Beau's lines).
Brittle nails that crack frequently have been noted with iron deficiency and thyroid or kidney problems. Splitting nails or pitting of the nails themselves are both seen with psoriasis. Low levels of Vitamin C, folic acid, and certain proteins in the diet are also known to cause nail splitting. Changes in nail shape can also give some information about underlying health. Nails that grow in a spoon shape can be associated with a deficiency of either iron or vitamin B12. Finally, changes in nail color can also be significant. White lines in the nail can be seen in patients with live problems, while whitish spots in the nail itself are most often caused by local trauma or injury to the nail bed. A gradual yellowing of the nail can be associated with many things, including liver or kidney disease or chronic infections.
