What can my doctor do?

Your doctor will take a detailed history from you and/or your parents. Physical examination will be carried out. Investigations will be done such as blood test, X-rays and other necessary investigations to look for possible causes.



How can these changes be stopped?

There are 2 possible options:

  • Treat the underlying condition (such as an ovarian or brain tumor)
  • Hormonal therapy to treat any hormonal imbalance


How can I catch up with my friends?

Specific hormonal treatment for delayed puberty will be determined by your doctor based on:

  • Your age, overall health and medical history
  • Extent of the condition
  • Your opinion or preference



Outcome is good with early detection and treatment.
