This is what the nails say about your health

Whether short, long or painted – nails can reveal a lot about people, but most of all about their health. Some changes may indicate diseases. KUKKSI reveals what you should pay attention to and when you should rather see a document.

Nails should not only look good, they can also tell a lot about our health. In healthy conditions, the nails are quite smooth on the surface, in the nail bed area they are pink and are long or wide – this is innate in this case and cannot be affected. Sudden changes or discoloration in the nail bed can indicate disease or a nutrient deficiency.

These changes can indicate diseases

longitudinal grooves

The longitudinal grooves are actually completely harmless – if you have them, you don’t have to worry too much. Mostly older people get them too. However, if you drink too little, longitudinal grooves may appear thicker.

transverse grooves

It’s a little different with the transverse grooves – these can actually indicate a disease. There may be an insufficient supply of nutrients, but they can also appear after a finger is injured. However, transverse grooves can also be a warning sign for very serious illnesses, including heart disease or infections.

Brittle nails

This can be a sign that your body is not getting enough nutrients, particularly you may be deficient in zinc or vitamin B. This also affects your nails, which are usually brittle.

The nails curve down

There is also a shortage here – with oxygen! That’s why you should definitely take downward curving nails seriously. This may be an indication of cardiovascular disease, but there may also be something wrong with the liver and lungs. If so, you should definitely see a document!

Yellow discoloration

If your nails turn yellow and are also brittle, there may be a fungal infection behind them. In the worst cases, this can also lead to nail fungus (onychomycosis) – although this can be cured, overall it is very annoying.


If you pinch or squeeze your finger somewhere, then the blackening of the nails is not particularly dramatic at first – these are bruises under the nails, which disappear again after a certain time and grow. But things are a little different if a dark discoloration suddenly appears – there may be a mole or skin cancer behind it. This means: In this case, it is essential to have it checked by a doctor.

Blue nails

On the other hand, if your nails tend to be blue, the winter cold is probably to blame. However, if they work this way for a long time, anemia may be behind it. The nail will not get enough blood flow in this case. Already read? Nail biting is really that dangerous!
