Mom worries how can I be underweight without eating disorders?

Need Good Evaluation. If you are underweight and have not been intentionally restricting your calorie intake, then it would be a good idea to undergo a thorough physical evaluation to make sure there are no causes for your weight loss that need to be revealed.
By definition. By definition, some people will be underweight for height by standards created when studying large populations.Within this group (5%) there are some that are culturally/genetically slim but also include some with underlying medical conditions that prevent them from achieving a more normal weight for height.
