There are a few conditions that give classical nail changes. Psoriasis is a good example it produces characteristic pitting.

Finger clubbing is also an important nail condition, however it may indicate a large number of different systemic diseases.

Splinter hemorrhages are longitudinal thin lines, red or brown in colour, that occur beneath the nail plate.

They are visible when capillaries within the epidermal ridges leak . While splinter hemorrhages may denote benign problems such as local trauma, psoriasis, or localised fungal infection, they are a classic finding in patients with endocarditis.





The white spots on nails (Leukonychia), often associated with various conditions such as calcium deficiency are in fact non-pathological.How can you tell medical conditions from finger nails?
Well,


With a lack of certain vitamins in the diet or certain medications being taken, the nails will change color or have a very brittle texture.


One interesting thing that I have found is that anyone who is missing certain vitamins, or suffering from malnutrition, will actually have ridges as the nail grows out. These are quite noticeable bumps that develop as the nail grows. They can be a dropping off point, or even more interesting with those with eating disorders, waves in the nail.





Fascinating stuff.How can you tell medical conditions from finger nails?
some
any blemishes (spots of white etc) that you can see in your fingernails are caused by impurities in your blood etc. These can indicate the presence of toxins and the like.
yes if you press down on them they go white then the blood rushes back in and they go red again...try it. doctors use this for some sort of heart and blood problems diagnosis i think.
Some conditions, yes.
Some minor conditions such as eczema, psoriasis, lack of iron or zinc and arthritis

See the little white flecks in your finger nail, and i don't mean the white growing tips, but little flecks, they are an indication of too much or too little calcium in your diet, I know, I was diagnosed with a calcium deficiency when i was a kid :o)
Finger nails show past trauma in a person's life...if they are very ridged, this would be evidence of recent emotional or physical trouble.





There are probably other signs, but that it the one I'm sure of.
