Medical scales are specialized devices used to measure a person's weight accurately. They are commonly found in hospitals, clinics, and doctor's offices, helping healthcare professionals monitor patients' health. These scales can vary in design, from simple mechanical models to advanced digital versions that provide additional information, such as body mass index (BMI). In addition to measuring weight, some medical scales are equipped with features that assess other health metrics. For example, bioelectrical impedance analysis scales can estimate body fat percentage and muscle mass. This information is valuable for doctors in creating personalized treatment plans and tracking a patient's progress over time.
