All causes of grooves in the fingernails at a glance

There are many causes of ridges in your fingernails. Some are harmless and part of the natural aging process, while others may indicate specific health conditions .

Here are some of the most common causes of ridges in fingernails to help you better understand the signals your nails are sending:

Aging process: As we age, longitudinal grooves in the fingernails are a common phenomenon. These types of grooves are usually harmless and a natural part of aging. They often appear as fine, longitudinal lines on the nails.
Vitamin and nutrient deficiencies: A deficiency in certain vitamins and nutrients can manifest itself in the form of ridges on the fingernails. For example, iron deficiency can lead to wavy fingernails, while a deficiency in B vitamins can lead to dents in the fingernails .
Thyroid disorders: Thyroid problems, such as hyperthyroidism, i.e. an overactive thyroid, can cause nail changes . Longitudinal grooves in the fingernails can therefore also be an indication of a thyroid disorder.
Stress and trauma: Acute or chronic stress, as well as physical trauma, can cause transverse grooves in the fingernails. These grooves, also known as Beau's lines, are formed when nail growth is temporarily disrupted.
Inadequate nail care: Incorrect nail care or excessive use of nail polish and nail polish remover can weaken nails and cause ridges to form. It is important to take proper care of nails and avoid harsh chemicals.
Skin diseases: Certain skin diseases such as psoriasis can also cause grooves in the fingernails. These often appear as dot-shaped dents or as deep transverse grooves.
Harsh cleaning products and chemicals: Regular contact with harsh cleaning products and chemicals can damage the nails and nail bed, causing them to become ridged and brittle. Wearing gloves when handling such substances can help protect the nails.
Genetic predisposition: In some cases, ridges in the fingernails can also be genetic. If family members have similar nail structures, this could be an indication that the ridges have a hereditary component.
Chronic diseases: Certain chronic diseases such as rheumatism or diabetes can also cause changes in the fingernails, including the formation of grooves.

These conditions can affect blood circulation and nutrient supply to the nails, which can lead to visible changes.

These causes provide a first clue to understand the health of your nails . If you notice persistent or worrying changes in your fingernails or toenails, it is advisable to consult a specialist.

FAQ

Does age play a role in the formation of grooves in the fingernails?

Yes, age can play a role in the development of ridges in the fingernails. As we age, cell regeneration slows down, which can lead to a change in the nail structure.

This can encourage the formation of grooves. Older people are more likely to notice longitudinal grooves in their nails, which is a normal part of the aging process.

Can medications cause ridges in fingernails?

Yes, certain medications can cause ridges in your fingernails. Drugs that affect nail growth and structure, such as chemotherapy drugs, can cause changes such as ridges.

If you suspect that a medication is causing ridges in your nails, you should discuss it with your doctor.

How long does it take for ridges in fingernails to heal?

The time it takes for ridges in fingernails to heal depends on several factors, including the cause of the ridges and the rate at which the nails grow.

In general, fingernails grow about 3 mm per month, so it may take several months for ridges to grow out completely.

However, good care and nutrition can effectively support the healing process.
