Having clean, healthy fingernails can indicate healthy conditions. When your fingernails are very pale, or even white, that could mean that there is a medical issue that needs to be dealt with. If the issue is with one finger, the problem could be confined to that area. But if the problem is on all your fingers, that could indicate a systemic problem in your body that needs to be attended to immediately.

There are many problems that can cause this condition. If it is one finger or several fingers on the same hand, this might be the result of trauma. Getting your hand caught in a door, or otherwise dealing with a crushing type of injury could lead to white nail beds.

Another problem might be underlying medical conditions, such as diabetes, which lead to problems with oxygenation of the fingertips.


This can make your nail beds look white or even give them a bluish tint. In addition to diabetes, there are other serious medical problems that can lead to white nail beds on all your fingers. This might include malnutrition, severe anemia, cirrhosis of the liver, or kidney disease.

Though it is important to mention your white nail beds to the doctor at your next visit, it might not be cause for serious alarm. However, other problems with your nails, in addition to white nail beds, might mean that you should get attention immediately. These include fingernails that are suddenly thickening, distorting in shape, or developing raised ridges. If there is any problem with your fingernails that changes their appearance, your doctor might want to run tests to figure out what the problem is. This can include testing on the nails itself, or blood work to rule out any underlying medical conditions. What Can Nail Color Indicate? 1. White nail

Remember that if you have white nail beds throughout your life, it probably means nothing – that’s just the way your nails look. But if the change comes on over time, or happens later in life, it might mean that you have a problem need to be diagnosed by your doctor. Such a problem can include renal failure, congestive heart failure, hepatic cirrhosis, diabetes, and some forms of lymphoma. 2. Blue nail

When the nail bed appears to be blue, that is an indication that your fingertip is not getting enough oxygen through the blood that flows there. This might mean you have lung trouble, including emphysema or asthma, or it might be an indication of anemia or other problems with red blood cells. 3. Yellow nail

Unlike white nail beds, if your nails are yellow, that could mean a systemic problem, such as diabetes, liver problems, or respiratory trouble. This is especially true if the nail is yellow or orange in color and thickens or curves into the cuticle. This is often a clear sign of pulmonary disease or lymphedema – it is actually called yellow nail syndrome. 4. Green nail

In most cases, green nail beds indicate a short-term problem, such as an allergic reaction to cleaning agents or something you touched, an infection of the nail itself, or a fungal infection in the area around the nail. But it might also be a sign of advanced emphysema. 5. Grey nail

Nails that turn grey might be indicative of systemic problems that have gone on for a long time, such as lung problems, emphysema, cardio-pulmonary disease, glaucoma or arthritis. It might also stem from malnutrition or edema, also known as swelling or water retention. Some people who have operations wake up to temporary grey nails, but this often resolves quickly. 6. Red nail

Red nail beds are often a serious concern that deserves an immediate trip to the doctor. The problems associated with red nail beds include heart disease, high blood pressure, stroke, lung disease, or carbon monoxide poisoning. They might also indicate a brain hemorrhage. Obviously, any of these issues are an emergency situation. Tips for Caring Your Nails
