You didn't deliberately lose weight. It's definitely not normal to lose 8 pounds a month. What you have to do now is to go to the hospital for examination. The first step is to measure your blood sugar. When blood sugar is high, you will lose weight soon. Step two, check the thyroid gland. People with abnormal thyroid are either thin or fat. The third step is to check whether there is a tumor. There are many tests, such as blood test, B-ultrasound, B-ultrasound, nuclear magnetic resonance, etc. In short, I hope you don't bother to check. For your own health, you can rest assured to check early.
