Our nails naturally develop slight vertical ridges as we age. However, severe and raised ridges can be a sign of iron deficiency anemia. Nutritional deficiencies, such as a lack of vitamin A, vitamin B, vitamin B12 or keratin can result in fingernail ridges. Hormonal changes can also cause ridges to appear.
