If you look at your nails, you will notice a light area at the base. It is called the lunula. Changing the color , shape and size of the lunula can mean not only that you have a certain disease, but also that you are predisposed to it. With this type of diagnosis, you can detect the problem in time and take appropriate action.
Lunula changes on the same finger
The lunula of the little finger should usually be almost invisible or completely absent. It is linked to the functioning of the kidneys, the small intestine and the heart . A large lunula can indicate high blood pressure.
On the ring finger, it corresponds to the work of the reproductive and lymphatic systems. A poorly marked lunula may indicate problems with the metabolism.
In the middle finger, it corresponds to the functioning of the brain and the cardiovascular system. The absence of a lunula can indicate problems with the blood vessels and high blood pressure.
On the index finger, the lunula may be absent or noticeably reduced due to poor functioning of the intestine, pancreas or due to chronic diseases of the upper respiratory tract.
On the thumb, it reflects the functioning of the lungs and the spleen. It is the largest of all the lunulae and its size should not be more than 25% of the total length of the nail. It can be remarkably reduced in people who smoke or have high blood pressure.
Lunulae that are too large
Lunulas are considered large when they occupy a third (or more) of the nail. It can signal problems with the cardiovascular system, altered heart rate and low blood pressure.
Often times, large lunulae can be seen in athletes and people whose activity is related to heavy physical labor. If the person does a lot of sports, large lunulae may appear under severe stress.
Small lunules that barely reach the surface of the cuticle are a sign of low blood pressure and circulation problems. This can be a sign of a weak immune system, a slow metabolism, but also a lack of iron and vitamin B12 in the body.
If the lunules are visibly isolated from the rest of the nail by a transverse line, this indicates that you have problems with blood sugar levels and it is advisable to watch for a risk of diabetes.
Don’t panic if you can’t see lunulae on your or your children’s nails. In young people, they are often invisible and appear over time. In adults, they may not come out due to a physiological peculiarity of the anatomy of the nail.
However, the disappearance of the lunules is considered by modern medicine to be one of the symptoms of blood circulation problems. A study has shown that the absence of lunules is often linked to thyroid problems, but also to a lack of vitamin B12 and iron.
