The ecstasy is a very complicated syndrome of many diseases caused by metabolic disorders, abnormal taste and improper diet management. In a broad sense, the eclipse also contains evil. People with this condition continue to bite non-nutritional substances such as dirt, paper, dirt and so on. In the past, people thought that the eclipse was mainly caused by the lack of trace elements such as zinc and iron. At present, more and more doctors believe that pica is mainly caused by psychological factors. But there is no substantial progress in its true causes and treatments. I suggest you check the trace elements first.
