Let’s talk about Specks under your fingernails
Looking into your fingernails once in awhile is a good health habit, as it is a good health indicator that you may not be familiar with.
If you observe dark spots under your nails, and if you have not banged your fingers recently, it could point out to an infection in the lining of your heart or valves. This condition is called endocarditis and valvulitis, respectively.


You can also get these specks with diabetes, and such people are two to four times more likely to have heart disease and stroke.
Let’s discuss about Pale & white Nails Normal color of the fingernail is pinkish due to minute capillaries with red blood in them. If you press on the nail, it blanches, because the blood moves away from the capillaries. On releasing the pressure, the color comes back due to capillary return. If the capillary return is prompt means that your heart is pumping blood efficiently.
So that would be the first clue for good heart function.
Though healthy nail plate is pink in color, your nail bed would be white, as it grows off the nail bed.
If you are anemic you will have very pale fingers like as if you have bled a lot. You need to see your doctor to do a full blood count to check what is brewing up.
In congestive heart failure too, the nailbeds will be pale, because the heart is not pumping blood efficiently due to the heart failure.
Another condition you get pale fingernails is- liver disease. You palm become bright red and we call it ‘liver palms. This is due to abnormal hormone levels in the blood.
Low protein stores due to malnutrition will also give pale nails. This condition is referred to as ‘Hypoalbuminemia’ In chronic kidney failure towards the terminal stages with loss of protein in the urine, you may get pale nails.
Yellow fingernails-Yellow nail syndrome When women use nail polish for a long time, the nails could turn yellow.
However, yellow nails could be due to a fungal infection, internal malignancies, lymphoedema, chronic bronchitis and COPD, diabetes, rheumatoid arthritis Psoriasis and thyroid disease.
