You need to gain weight!
You must gain at least 2 kg. Then BMI will be normal.
The Body Mass Index (BMI) is calculated using the following formula: multiply height in meters by your height in meters and then divide body weight in kilograms by the resulting multiplication result. So, for example, for a height of 1.75 (in meters) and a weight of 63 (in kilograms), BMI is 20.57 (BMI = first increase the growth of 1.75 by the growth of 1.75, and then divide the weight of 63 by the resulting multiplication result). If the result of the calculation is in the range 18.5 - 24.99, then this is the norm.
