BMI is considered unhealthy if <16 or >28. >28 is obese; 25-28 is overweight; 16-18 is underweight; and < 16 is "severely underweight". By plotting the weight over time on a standardized growth curve (available from the CDC), you can see if an individual is tracking appropriately or falling off the curve. Falling off the curve (crossing two percentage lines) is a big red flag. Athletes may be underweight without being unhealthy, and this may actually given them a competetive advantage in some sports. BMI is not the same as body fat percentage, which must be calculated by various skin fold thickness measurements or by using a water tank scale. When we assess people to determine whether or not they are at an unhealthy weight, we look at a variety of additional factors, such as how they feel, whether or not they are menstruating, their lab results (Tot protein, albumin, blood counts, glucose, electrolytes, and liver function), and their bone density. Osteopenia and osteoporosis develop more frequently in underweight athletes, as you might expect. Eating disorders are diagnosed when individuals have unhealthy and obsessive concerns about their weight which cause them to starve themselves, exercise excessively, or to perform ritualistic behaviors such as inducing catharsis through various means after binging. People with eating disorders frequently know their behavior is abnormal, but not always. Sometimes their perception of reality is flawed or they lack insignt. In such instances, family members or loved onces may need to confront the individual or provide the physician with information which, in light of the objective data, can confirm the presence of an eating disorder. Information on the Female athlete syndrome / triad is well documented in the literature, and may be of interest to those involved in the training, nutrition, and guidance of female athletes.
