The best measure of whether you are a healthy weight is the body mass index (BMI). This is calculated using your weight and your height. In adults, a healthy weight range is a BMI of 18.5 to 24.9. If your BMI is under 18.5 then you would be considered underweight.
Women with a BMI of less than 18.5 are considered underweight. The average woman's height is 5 feet, 4 inches. If you weigh 107 pounds or less at this height, you are considered underweight with a BMI of 18.4. A healthy weight range for that woman would be 108 to 145 pounds.

It may be that you have a fast metabolism (meaning your body burns energy from food at a fast rate than the people around you) or you're just naturally slender. For some people, underlying health conditions and certain medications and treatments can make it difficult to reach and/or maintain a healthy weight.
BMI values of less than 18.5 kg/m2 are considered underweight. BMI values between 18.5 kg/m2 to 24.9 kg/m2 are healthy. BMI values between 25 kg/m2 to 30 kg/m2 are overweight. BMI values greater than 40 kg/m2 are considered obese.
