Amenorrhea means the absence of menstrual periods. It can have many explanations, including pregnancy, hormonal contraception, breastfeeding, menopause and medical conditions. Sometimes inadequate food intake, heavy training or stress contribute, but these are not safe assumptions to make without assessment.
A clinician can help establish the cause and decide whether tests or a referral are needed. If you have missed three periods in a row, or are concerned about other symptoms, arrange a GP appointment. Pregnancy testing may be relevant sooner. This website explains the questions to ask and the supportive role of diet and lifestyle; it does not diagnose the reason for a missing cycle.

Read the free guides nowFor diagnosed functional hypothalamic amenorrhea, correcting an energy imbalance can be part of treatment. That may involve eating more, improving nutrition, reducing exercise, and sometimes gaining weight with professional support. It is not a plan for every cause of amenorrhea.
Start by making regular meals easier, noticing training demands and getting help if food or exercise feels difficult to manage. Rest and psychological support can also be useful parts of an individual care plan. There is no universal hormone-balancing food or guaranteed recovery timetable. Our approach focuses on practical support, sensible questions and preserving your relationship with food while your healthcare team investigates and treats the underlying cause.

There is no diet that treats every cause. Nutrition changes may help diagnosed functional hypothalamic amenorrhea, but pregnancy, hormone conditions and other causes need appropriate assessment.
The NHS advises seeing a GP after three missed periods in a row, or sooner when you have concerns or accompanying symptoms. If pregnancy is possible, consider a pregnancy test.
Do not start calorie restriction to treat a missing cycle. In an energy deficit, more restriction can work against recovery. Ask for individual advice.
Irregular or absent periods do not provide reliable contraception. Discuss pregnancy testing, contraception or fertility concerns with a clinician.
Exercise changes depend on the cause and your health. A clinician may advise reducing training in an energy deficit, but there is no universal exercise rule.
