Question
My child has been diagnosed with iron and zinc deficiencies through trace element tests. After taking calcium, iron, and zinc supplements for a week, their lips have become notably black. They were normal before the supplements. What could be the reason for this?
Answer
There are two situations that can cause lips to turn white. One is an external cause, which is the excessive thickening of the keratin layer on the lips. The other is an internal cause, involving multiple organs such as the heart, lungs, liver, and blood, and could also be due to poor digestion. Do not ignore lips turning white; see a doctor immediately. First, consult a cardiovascular specialist. It is recommended that you visit at least a level three A-grade hospital like ours. You should also provide a detailed description of your other symptoms, such as how you feel after doing many intense exercises, your sleep quality, and your dietary habits. Are there any cardiovascular issues in your family?
