Understanding their results

Your patient’s BMI is below 18.5: this suggests they are underweight. You may want to speak to your patient about healthy ways they can gain weight.

Your patient’s BMI is 18.5–24.9: this is considered healthy and normal.

Your patient’s BMI is 23–27.4: They may be overweight. Suggest to your patient that they make small changes to increase their physical activity and eat a healthier diet. Sustainable changes to their lifestyle can help them to reduce their risk of health problems in the future.

Your patient’s BMI is above 30: this is considered obese. As obesity is linked to many health issues, such as TD, it is important they start to make changes to start living a healthier lifestyle.

Encourage your patient to track their BMI throughout their testosterone therapy to see how it changes as they start to live a healthier lifestyle
