Do hormones affect energy levels?

Hormones play a vital role in many body processes, so when they are out of balance, they can disrupt the normal functioning of our body. This can lead to various symptoms, including reduced energy levels and feeling tired all the time.

In this article, we explore how hormones affect energy levels and some of the known links between certain hormones and exhaustion. This will help you understand if hormones could be the root cause of the symptoms you’re experiencing and how testing can help you understand more about your energy levels and overall health.

How do thyroid hormones affect energy?

The thyroid gland is responsible for producing hormones that help control your metabolism, the chemical reactions in your body’s cells that change food into energy.

If your body makes too many of these hormones, you have an overactive thyroid (hyperthyroidism), but if it doesn’t produce enough, you have an underactive thyroid (hypothyroidism). Both can affect your energy levels in different ways:

Underactive thyroid - your body processes start to slow down, making you feel tired, cause you to gain weight, and experience problems with your memory.

Overactive thyroid - you may suffer from restlessness or anxiety, which can make it more difficult to switch off at night, causing problems with your sleep that can lead to increased tiredness.

How does oestrogen affect energy?

Oestrogen is often known as the female sex hormone but is present in both males and females. It is responsible for various functions and plays a key role for women in puberty, the menstrual cycle, and pregnancy.

It is normal for female oestrogen levels to fluctuate throughout their lifetime. However, lower levels are typically associated with tiredness or a lack of energy. This is most commonly seen in women approaching or going through menopause, as during this time, oestrogen levels naturally start to decrease.

Oestrogen and your monthly cycle

Oestrogen levels also play a vital role in the menstrual cycle, and rising and falling oestrogen hormones are known to impact energy levels.

Oestrogen levels increase in the first two weeks of the monthly cycle (the follicular phase and during ovulation), which can often boost energy levels.

However, by the third week of the cycle, oestrogen levels fall, which can lead to a drop in energy and feelings of fatigue.

Does progesterone make you tired?

There is no simple way to answer the question, “Does progesterone make you tired?” depending on the individual, the answer can be yes or no.

Progesterone is an important hormone in a woman’s monthly cycle and in supporting early pregnancy. Although high levels of progesterone hormones and exhaustion are linked, progesterone can also help improve sleep quality, which for people who don’t normally sleep well can result in them feeling less tired than normal.

Progesterone and the menstrual cycle

Levels of progesterone are generally at their highest in week three of a woman’s cycle or during the early stages of pregnancy. This increase in progesterone can make women feel more tired than usual. However, as mentioned, for people who have trouble sleeping, heightened progesterone levels during this time can also help improve their sleep, which may boost their energy levels slightly.

If an egg isn't fertilised in week four of a woman’s monthly cycle, progesterone levels fall, which can cause problems sleeping and lead to increased tiredness.

Progesterone and menopause

Women’s progesterone levels also naturally decrease during menopause. For many women, this can impact their sleep and, as a result, leave them feeling more tired than usual.

Signs you need an energy assessment

Feeling constantly fatigued can be frustrating, and while hormones play a role, there are many other potential contributors, including nutrient deficiencies, lifestyle factors or other underlying health conditions.

You may want to consider a Core Vitamins or Advanced Nutrients and Vitamins Profile test if you notice:

• Fatigue - feeling tired even after rest

• Trouble sleeping - too much or too little sleep

• Difficulty enjoying activities you normally like

• Unexplained weight changes

• Brain fog or reduced concentration

• Low mood or increased irritability

Test your energy levels

At Bluecrest Wellness, our Core Vitamins or Advanced Nutrients and Vitamins Profile tests are designed to assess key nutrients that play a crucial role in energy, metabolism, immunity, and overall wellbeing. By measuring markers such as vitamin D, B12, folate, iron, magnesium and zinc, these tests can provide insights into whether deficiencies or imbalances may be contributing to fatigue or low energy.

Your appointment is quick, convenient, and clinic-based. After your test, you’ll receive a clear, personalised Results Report explaining each reading in plain language, with easy-to-understand green, amber, or red flags so you can see at a glance where any potential concerns lie.
