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 nail ridges can be a sign of malnutrition. Malnutrition is a condition that results from eating a diet that does not contain enough nutrients or the right balance of nutrients for good health. It can also result from an inability to absorb or use the nutrients that are consumed. Malnutrition can cause a variety of symptoms, including changes in the appearance of the nails.
Horizontal nail ridges can be a sign of a vitamin or mineral deficiency, which is a common consequence of malnutrition. For example, iron deficiency may cause vertical ridges in your nails, while a deficiency in zinc, vitamins A, C, or D can also contribute to the development of nail ridges. Biotin is also highly recommended to aid in nail health, although more research is needed to understand the full extent of its benefits.
If you notice horizontal ridges in your nails, it is important to see a healthcare provider to determine the underlying cause. Treating the underlying cause of the ridges, such as addressing any nutritional deficiencies, can help to improve the appearance of your nails over time. With proper treatment and care, smoother nails may grow in to replace the ridged nails.
In addition to malnutrition, horizontal nail ridges can also be caused by other factors such as nail injuries, infections, or underlying health conditions. Therefore, it is important to consult a healthcare professional to determine the specific cause of the ridges in your nails and to receive appropriate treatment or advice.
