What doctor should I go to if I have a problem with the absorption of zinc?

First of all, I encourage you to verify the following issues: 1. Does the zinc preparation you were taking have the status of a drug and contained the appropriate dose of zinc? There are drugs with zinc on the market, such as: - Zincas forte: https://www.gdziepolek.pl/produkty/85973/zincas-forte-tabletki/apteki - Zincas: https://www.gdziepolek.pl/produkty/85972/zincas-tabletki/apteki 2. Have you not taken foods with zinc that may reduce zinc absorption? These are, for example, phytates present in m.in cereal products, nuts, legumes. They form insoluble complexes with zinc in the intestines that are not absorbable. If, after introducing appropriate modifications, the level of zinc does not improve, you should see a doctor, e.g. with a gastrological or internal medicine specialization. However, I suggest going to your GP first, who can give you another cause of the problem and refer you to the appropriate specialist.
