A mild thinness BMI is defined by the World Health Organization (WHO) as a Body Mass Index (BMI) between 17.0 and 18.5 kg/m², falling within the broader underweight category (below 18.5) but above moderate thinness (16.0-16.9) and severe thinness (below 16.0). This classification helps identify nutritional status, though individual health should be assessed by a professional, as BMI doesn't account for muscle mass.
BMI classification
Mild Thinness: 17 to 18.5. Normal: 18.5 to 24.9. Overweight: 25 to 29.9. Class I obesity: 30 to 34.9.
Ozempic is typically recommended for individuals who have a BMI of 30 or higher, which falls into the obese category, or for those with a BMI of 27 or higher who have additional health concerns such as high blood pressure, type 2 diabetes, or high cholesterol.
If your BMI is: under 18.5kg/m2 – you are considered underweight and possibly malnourished. 18.5 to 24.9kg/m2 – you are within a healthy weight range for young and middle-aged adults. 25.0 to 29.9kg/m2– you are considered overweight.
"Ozempic hands" is a slang term for the visible changes in hands due to rapid fat loss from GLP-1 drugs like Ozempic, making them look thinner, bonier, and more aged with prominent veins, tendons, and thinner skin, as subcutaneous fat diminishes and skin doesn't fully contract quickly. It's not a formal diagnosis but a common cosmetic effect of significant weight loss, similar to "Ozempic face".
Most people taking Ozempic see big changes within the first 2 to 6 months depending on the dosage adjustments. Patients can expect 2 to 6 lb per month weight loss and a total of 10 to 15% or body weight loss for the period of 6 to 12 months.
Candidates for Ozempic treatment for weight loss include individuals who have a BMI of 30 or higher and those with a BMI of 27 or higher as well as at least one weight-related condition, such as high blood pressure, high cholesterol, or type 2 diabetes. Ozempic is not the right weight loss approach for everyone.

We found that the BMI in models of 17.1±0.9 was lower than the BMI of 17.5 set by the American Psychiatric Association as a cut-off for anorexia. Korean national standards classify a BMI lower than 18.5 kg/ ㎡ as underweight, 18.5-22.9 kg/㎡ as normal, and 23- 24.9 kg/㎡ as overweight or risk weight.
Starting at 25.0 (using your height in meters and weight in kilograms), the higher your BMI, the greater is your risk of developing obesity-related health problems.

Here is how BMI results are categorized for people age 20 and older: Under 18.5: underweight. 18.5-24.9: healthy weight. 25-29.9: overweight.
Key Milestones for Weight Loss with Ozempic
The standard Ozempic dose starts at 0.25 mg weekly and typically increases every four weeks to 0.5 mg, 1.0 mg, and up to a maximum of 2.0 mg. Significant weight loss usually begins at the higher, therapeutic doses (1.0 mg and 2.0 mg), not the initial starting doses.
It is not known if Ozempic® will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people.
