It doesn't matter what you lose weight and whiten. Personal health is the most important.
Personally, I think we can discuss it.
Record your daily diet and exercise, sleep time, and the time and length of illness. If you are a girl, you should also record your physiological cycle. A year later, or a year and a half later, the general health curve should come out. Should I go to the hospital for a comprehensive physical examination before recording? Oh, by the way, if you eat out, record the visual hygiene.
