Ideal body weight

Adjusted body weight = ideal body weight + 0.3 (actual body weight - ideal body weight)... 

Infants and children with maldigestion may have evidence of failure to thrive (below age-based normals in both height and weight), and adults may be near or below their ideal body weight despite apparent adequate caloric intake. 

Refer the patient for nutritional counseling if there is decreased caloric intake and weight loss. Compare actual body weight to ideal body weight. 

In patients younger than age 65 with overt hypothyroidism, the average LT4 replacement dose is 1.6 mcg/kg per day (use ideal body weight in obese patients25). If there is no history of cardiac disease, these patients may be started on the full replacement dose. The full replacement dose in patients over age 75 is lower, about 1 mcg/kg per day.26 In the elderly, the starting dose is 25 to 50 meg/day, and the dose is titrated to the... 

Dose per weight is based on ideal body weight. Children weighing more than 40 kg should be dosed as adults.

The product of U X V equals the production of creatinine during the collection period and, at steady state, should equal 20 to 25 mg/kg per day for ideal body weight (IBW) in males and 15 to 20 mg/kg per day for IBW in females. If it is less than this, inadequate urine collection may have occurred, and CrCl will be underestimated.

Figure 1.1 The body mass index (BMI) is a formula that calculates whether a person is an ideal body weight, overweight, or obese. The formula used to calculate BMI considers a person s weight and height. BMI has some limitations. It may not be accurate for people who are very muscular, such as bodybuilders, and people with very little muscle mass, such as the elderly. BMI is one of several factors health-care providers consider when they determine whether a person is overweight or obese. Note that this BMI chart is designed for adults who are age 20 or older.

Use actual body weight for all calculations. Adjusted body weight may be used for obese patients (>130% of ideal body weight). 

Obese patients (>120% ideal body weight) without contraindications should be started on metformin initially, titrated to about 2,000 mg/day. A thiazolidinedione (rosiglitazone, pioglitazone) may be used in patients intolerant of or having a contraindication to metformin.
