115 pounds lands precisely on the healthy-underweight boundary at the UK average height of 5ft 6in, giving a BMI of 18.5. In practice I would not treat this as a concern for a patient who has been stable at this weight for years and is eating well and feeling good. Where I pay closer attention is when a patient has arrived at 115 pounds recently from a higher weight, or when the weight is associated with fatigue, dietary restriction, or other symptoms. A BMI of 18.5 is technically the lower limit of healthy, and what sits just below that number matters as much as the number itself.
