Have you ever looked closely at your fingernails and noticed ridges? Don’t worry, you’re not alone. Ridges in fingernails are quite common and can be caused by various factors. In this blog, we will explore the possible reasons behind those ridges and what you can do about them.
Vertical Nail Ridges
According to a study from 2015, people often get small vertical bumps on their fingernails as they get older. This may be because cell turnover slows down with age. This is when new skin cells that are being made below the surface of your skin come to the surface to replace the dead skin cells that are being shed from the surface.
If you have other symptoms, like changes in the feel of your nails, it could be a sign of a health problem. In trachyonychia, also called “twenty-nail dystrophy,” the ridges may look shiny or break easily.
Iron deficiency anemia can also cause your nails to change shape and get straight bumps.
Horizontal Nail Ridges
2018 study found that Beau’s lines, which are deep, parallel bumps, are often signs of a dangerous disease. They might even stop the nails from growing until the problem is fixed. If Beau’s lines are there, you may also have acute kidney disease.
According to a study from 2015, when Beau’s lines appear on all 20 nails, it could be a sign of:
- mumps,
- parathyroid disease,
- uncontrolled diabetes,
- syphilis,
- lung diseases that cause high fevers for a long time, and
- zinc shortage.
- Beau’s lines could also be caused by chemo.
If you hurt your nails, you might get red or brown spots under them. If the color under your nails changes to dark brown, black, or red and you haven’t hurt your nails, it could be a sign of something more serious, like endocarditis or melanoma.
Reasons Behind Ridges on Nails
Aging
As we age, our nails tend to develop ridges naturally. These ridges, known as longitudinal ridges, run from the cuticle to the tip of the nail. They are often harmless and simply a result of the aging process.
Nutritional deficiencies
A lack of essential nutrients in your diet can affect the health of your nails. Ridges can be a sign of insufficient vitamins, minerals, or protein. Pay attention to your diet and make sure you’re getting a balanced intake of nutrients.
Dehydration
When your body lacks proper hydration, it can affect the health of your nails. Dehydration can lead to dry and brittle nails, which may develop ridges. Stay hydrated by drinking an adequate amount of water throughout the day.
Trauma or injury
If you have experienced an injury to your nail bed or frequently use your hands for activities that put stress on the nails, such as typing or playing instruments, it can result in ridges. The ridges may appear as a response to the trauma and usually grow out over time.
Medical conditions
Certain underlying health conditions can contribute to the presence of ridges in your fingernails. Conditions like psoriasis, eczema, thyroid disorders, and autoimmune diseases can affect the nail matrix and cause ridges to form.
If you have ridges in your fingernails, it is important to see a doctor to rule out any underlying medical conditions. In most cases, ridges are harmless and do not require treatment. However, if the ridges are severe or are accompanied by other symptoms, such as pain, swelling, or discoloration, it is important to see a doctor to rule out any underlying medical conditions.
