Written by Dr Muhammad Usman, MBBS: At this weight in an adult above 5ft 3in, the concern is not just the number itself but what it represents. A BMI below 17.5 at any adult height warrants clinical attention — the questions are whether this is the person's natural constitution, whether there has been recent change, and whether their nutritional intake is adequate. I am also mindful that this weight appears in searches by people who may be struggling with low body weight concerns. If that applies, a conversation with a GP is a supportive and confidential first step.
