Body mass index (BMI) is a health screening tool commonly used to determine someone's overall body composition based on their height and weight.
According to the Centers for Disease Control and Prevention (CDC), you are considered underweight if your BMI is less than 18.5.

Even if you're "underweight" according to the BMI chart, that doesn't mean you're "unhealthy." However, if you are underweight and have difficulty gaining weight, it may be time to see your doctor.

It is normal for your body weight to fluctuate within a small range. However, if you notice that you have unexplained weight loss that is not the result of intentional dietary or lifestyle changes, you should see your doctor to find out the cause.

If you don't have a medical condition that's making it difficult for you to lose weight or gain weight, your doctor may refer you to a dietitian.
