What You'll Learn
Vertical ridges in nails are often a sign of aging
Ridges in your nails are usually harmless but can mean different things. Vertical ridges are often a sign of aging, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau’s lines. According to 2022 research, ridges are usually due to aging. But they can also be a sign of improper nail care, nail trauma, vitamin deficiencies, or even a more pressing medical condition. If you have grooves and ridges in the centre of your thumb, you may have developed a habit of picking at (or pushing back) the cuticles on your thumbnails. Many people are unaware that they do this. A dermatologist may be able to help you break the habit, allowing healthy nails to grow out.
Vertical ridges in nails are often a sign of ageing. As we age, our nails can become thinner and more brittle, which can lead to the formation of vertical ridges. These ridges can run from the cuticle to the tip of the nail and are usually more pronounced on the thumbnails. While vertical ridges are often harmless, they can sometimes be a sign of vitamin or mineral deficiencies, such as a lack of calcium, vitamin D, or magnesium.
In addition to ageing, vertical ridges in nails can also be caused by other factors. For example, they can be a result of nail trauma, such as repeatedly picking at or pushing back the cuticles. This can cause the nail bed to become damaged, leading to the formation of ridges. Vertical ridges can also be a sign of certain medical conditions, such as thyroid disorders or psoriasis.
While vertical ridges in nails are usually harmless, it is important to be aware of any changes in your nails and to consult a doctor or dermatologist if you have any concerns. Changes in nail colour, texture, or shape can sometimes be a sign of an underlying health condition. For example, white nails can indicate trauma, anemia, dietary deficiencies, heart or kidney disease, or even poisoning. Curved nails can also be a sign of disease, and if you notice your fingernails starting to curve, it is recommended that you see a board-certified dermatologist.

Horizontal ridges can point to malnutrition
Ridges in your nails are usually harmless but can mean different things. Vertical ridges are often a sign of ageing, while horizontal ridges can point to issues like malnutrition, serious nail injury, or Beau's lines. Horizontal ridges can also be a sign of vitamin deficiencies, which can be caused by malnutrition. If you are experiencing malnutrition, it is important to address the issue and ensure you are getting the proper nutrients. This may involve making changes to your diet or taking supplements. It is also a good idea to see a doctor or dermatologist to get their advice and ensure that there are no underlying medical conditions causing the ridges. They will be able to examine your nails and determine if there is anything to be concerned about.
Malnutrition can occur when the body does not get enough nutrients, either from a lack of food or an unbalanced diet. This can lead to vitamin and mineral deficiencies, which can affect the health of your nails. Nails are made of a protein called keratin, which requires certain nutrients to be strong and healthy. If you are not getting enough of these nutrients, it can show up as ridges or other changes in your nails.
There are several types of malnutrition that can affect the body, including protein-energy malnutrition, micronutrient deficiencies, and specific nutrient deficiencies. Protein-energy malnutrition occurs when the body does not get enough protein or calories, leading to weight loss and muscle wasting. Micronutrient deficiencies, such as a lack of vitamins and minerals, can also affect the health of your nails. Specific nutrient deficiencies, such as a lack of iron or zinc, can also cause changes in the nails.
It is important to note that ridges in the nails can also be caused by other factors, such as improper nail care or nail trauma. If you are experiencing ridges in your nails, it is a good idea to examine your nail care routine and make sure you are not causing any damage to your nails. This includes avoiding picking at or pushing back your cuticles, as this can cause ridges and grooves in the center of your thumbnails. Additionally, trauma to the nails, such as hitting them or exposing them to harsh chemicals, can also cause ridges and other changes.
If you are concerned about the appearance of your nails, it is always best to consult a doctor or dermatologist. They can examine your nails and determine if there is an underlying cause for the ridges. In some cases, ridges in the nails can be a sign of a more serious medical condition, so it is important to get professional advice. By taking care of your nails and addressing any nutritional deficiencies, you can help promote healthy nail growth and prevent further issues.
