Visit your general practitioner, gynecologist or naturopath to do further investigations into why you are not menstruating. Some tests to consider are: complete hormone testing, thyroid profile, iron studies, coeliac serology, plasma zinc, vitamin D, full blood count and liver function tests.
Reduce high intensity exercise. Whilst moving the body is good, now is the time to lean into restorative movement such as yin yoga, bush walking, or gentle stretching. For some, limiting to meditation and breathwork is enough.
Include zinc rich foods in the diet, you need zinc to make hormones and zinc is required for all parts of the reproductive process. Zinc rich foods include: cashews, oysters, mushrooms, pumpkins, spinach, lentils and walnuts, and hemp seeds. Typically, vegetarian/vegans are low in zinc as zinc is often found in high amounts in animal products.
Nourish your body with regular meals and snacks focusing on a mix of protein, healthy fats, and complex carbohydrates. If you have a poor relationship with food & eating, seek the guidance and support from a counsellor or psychologist well versed in this, alternatively The Butterfly Foundation has wonderful resources for those who are experiencing disordered eating.
Depending on the cause of amenorrhoea, herbal medicines may be beneficial in restoring balance to the menstrual cycle. Herbs such as Vitex, Peony, Tribulus, Withania, Licorice, Dong Quai, or Shatavari may all be considered to stabilize hormonal function and revive a weakened menstrual cycle.
Whilst exploring plant medicines, and causes of imbalances within your health, before making any changes to your diet, medication or beginning any herbal or nutritional supplements it is vital to consult your G.P, naturopath, health care professional for personalised guidance and advice.
