Adolescent Hormonal Health

Changes in behaviour and temperament are normal in teens, however these changes can be minimised through hormonal support to help mood, mental health, weight balance and healthy skin.

What might cause a hormonal imbalance?

Hormonal imbalance occurs when there is too much or too little of a hormone in the blood. There are many causes but common contributors include:


Poor nutrition and an unhealthy lifestyle

Chronic stress

Environmental factors

Early onset of puberty

The onset of puberty is considered normal if it begins at age eight or later in girls or at age nine or later in boys. If these developments begin too soon, a child may be diagnosed with precocious puberty[i].

Delayed puberty

It's not always clear what causes delayed puberty. It may just be a tendency that runs in a family. Delayed puberty is generally more common in boys and may be evident if they show no signs of development by 14 years of age. In girls, delayed puberty should be investigated if their periods have not started by the time they reach 15 years of age [ii].

Male hormone imbalance

The symptoms of hormonal imbalance in teenage males may include loss of muscle mass, decrease in body hair and beard growth and difficulty concentrating [iii].


Responsible for maintaining healthy blood sugar, insulin resistance is common with PCOS and insulin may undergo significant changes prior to and during puberty [vii]

Thyroid Hormones

Too much thyroid hormone can cause anxiety, weight loss, heart palpitations, irregular periods and fatigue among other symptoms. Too much thyroid hormone is known as hyperthyroidism. Hypothyroidism (low thyroid hormone levels) can also lead to fatigue, weight gain, depression, dry skin, hair loss and irregular periods.

Female hormone imbalance:


This hormone increases during ovulation (when the ovaries release an egg). Low progesterone can cause symptoms such as headaches, anxiety and irregular periods. If progesterone is imbalanced it can have knock-on effects for oestrogen levels[v][iv].


Oestrogen dominance is very common, it can cause symptoms such as weight gain, tender breasts, mood swings and PMS. Too little oestrogen can also cause problems such as hot flashes, frequent Urinary Tract Infection, fatigue and poor concentration [vi].


Known as the stress hormone, too much cortisol could lead to weight gain, anxiety and depression in teen girls.

Common hormone disorders in teenage girls:


Common symptoms include acne, weight gain and patches of dark skin on the back of the neck. PCOS can also cause excessive hair growth on the face, back and abdomen and irregular or heavy periods.


Pre-menstrual syndrome includes symptoms such as mood swings, feeling upset, anxious or irritable, fatigue, insomnia, bloating, breast tenderness, headaches and acne.

Painful periods

Painful periods are common in teenagers. The brain is getting used to talking to the ovaries and uterus (known as the hypothalamic axis). Less commonly, period pain can be caused by an underlying medical condition.

Tips to ensure good hormonal balance and optimal health during adolescence

Maintain a nutritious diet

Quality proteins, nutrient-dense plant foods, and healthy fats provide the raw materials a teenager needs to manufacture hormones and build a healthy microbiome. The gut is intricately connected to every other system in the body, including hormone systems.

Regular exercise

Staying active reduces stress levels[viii]. It can also help regulate testosterone[ix].

Look after the liver

Avoid refined sugars and unnecessary additives and preservatives in the diet, ensure a good intake of cruciferous vegetables and leafy greens such as kale and broccoli. An overburdened liver may not effectively metabolise and regulate hormones such as testosterone and oestrogen, which results in high hormone levels in the bloodstream.

Manage stress

Meditation, yoga, Pilates, mindful breathing and exposure to nature are all great stress busters.

Prioritise sleep

Better sleep boosts mental and hormonal health as the body releases several crucial hormones during sleep. Lack of sleep can negatively affect mental health in teenagers[x].
