Question
If there are vertical lines on the fingernails, what trace elements might be lacking or what other causes could this be due to? How should it be treated, and what precautions should be taken?
Answer
The reappearance of vertical lines or cracks on the nail surface, extending from the tip of the finger to the base of the nail, may indicate intestinal inflammation, vitamin deficiency, iron deficiency, and other conditions. This situation may be caused by a lack of trace elements. If necessary, it is recommended to visit a hospital for relevant examinations and treatment. If diagnosed with a deficiency of trace elements, active digestive treatment should be pursued.
