Ideal body weight Practice, Theory, and Evidence
Ideal body weight is frequently confused with body mass index. However, ideal body weight is used to calculate the dosage of medications, whereas body mass index calculates the healthy weight of an individual.
It is important to note that the IBW took what was considered an attractive height and weight at the time it was developed as its primary consideration.
Calculations of medications using the ideal body weight have become increasingly complex in recent years as physicians and pharmacists account for the flaws in the design of the ideal body weight ratio. Body composition, genetics, and diet are all factors influencing the body's absorption of drugs that the ideal body weight calculator does not take into account. Additional modifications in dosing may be required for individuals who are over or underweight according to the body mass index.
