At 28 years, 5'2" and 53 kg, your BMI is around 21.4, which is within the healthy range. A drop from 56–58 kg to 53 kg does not necessarily mean that you're unhealthy, but unintentional or ongoing weight loss should be evaluated.
Next Steps
Consult a physician/GP to assess the cause of the weight loss, especially if the weight is continuing to fall.
Review appetite, meal intake, stress/sleep, bowel habits and menstrual cycle.
