Relative Energy Deficiency in Sport

Does bleeding on a contraceptive pill prove recovery from low energy availability?

Author: Dr. Jiwu Chen

Doctor’s answer

No. Withdrawal bleeding can mask natural cycle recovery and does not replace improved fueling and training adjustment. Amenorrhea needs evaluation for pregnancy and other endocrine causes, plus bone and nutritional health. Do not change prescribed medication independently.
