A lot of people suffer from hormonal imbalance, but they are completely oblivious to it.

The term "hormonal imbalance" refers to a condition in which hormone production is altered and the relationships between the various hormones undergo significant changes, but not big enough for these to be regarded as medical conditions.

As mentioned in our previous blog, hormonal imbalances are sometimes completely physiological – for example, they can occur during puberty, menstruation or the menopause - yet these can have considerable consequences on women’s health and well-being. Although we know that there could be an imbalance in our hormones, it’s not always easy to understand what the particular cause of the imbalance is.

So, what happens if there are too many, or not enough, hormones in our body? Well, since hormones are crucial when it comes to regulating some main bodily functions; including metabolism and appetite, sleep cycle, reproductive and sexual function, growth and development, mood and stress levels, an imbalance in hormones can have several consequences. But what are they? Let’s have a look…

1. Lack of Sleep

The different phases of a woman's cycle are associated with significant physiological and hormonal changes that often alter normal sleep patterns [1]. This problem may be linked to insufficient progesterone production; if levels of this hormone are lower than usual, it can be more difficult to fall into a deep sleep or to fall asleep at all. Low estrogen levels, especially during the menopause, can trigger hot flushes and night sweats, which can also interfere with a normal sleep cycle.

2. Skin problems

If you suffer from severe acne, the problem may be related to excessive androgen production levels. Excessively high levels of testosterone lead to an increase in sebum (oily skin), often resulting in the appearance of pimples. In some cases, it can also lead to facial hair growth [2, 3, 4]. This imbalance could also be a symptom of polycystic ovary syndrome (PCOS). In contrast to oily skin, dry skin is often associated with menopause.

3. Chronic fatigue

This problem can often be caused by an imbalance in progesterone levels, cortisol (also known as the "stress hormone") and thyroid hormones [5]. Additionally, if the levels of these are too high, it can slow down bodily functions and affect energy levels.

4. Mood swings and depression

Frequent, distinct changes in hormone levels trigger emotional instability, especially in the premenstrual phase (PMS). This instability is reflected with feelings of irritability, anger, sadness and anxiety [6, 7]. Sex hormones also play a key role in postpartum depression; the onset of depressive symptoms that are temporarily associated with the big drop in hormone levels that occurs when giving birth.

5. Weight gain

As much as lifestyle, diet and exercise are key factors towards maintaining a healthy weight, hormonal balance also plays an important role [8]. Sudden weight gain can be a clear sign that there is an imbalance. Since hormones regulate metabolic functions, high estrogen levels can influence the secretion of leptin: a hormone that regulates the feeling of hunger and satiety. Hypothyroidism (where the thyroid gland does not produce enough thyroid hormones), polycystic ovary syndrome (PCOS) [9] and menopause may also cause weight gain, especially around the abdomen. Other symptoms of hormonal imbalance that shouldn’t be overlooked include a constant feeling of thirst and the need to urinate frequently.

6. Headaches and migraines

Migraines are predominantly experienced by women. They are not only brought on by menstruation, pregnancy or menopause, but also by hormonal contraceptives and hormone replacement treatments [10]. Headaches usually occur before or during the menstrual cycle, pregnancy and the menopause. Fluctuations in estrogen levels affect the vascularization of the brain [11].

7. Vaginal dryness

A reduction in estrogen levels causes significant changes to the vaginal wall and mucosa. Symptoms of so-called "vulvovaginal atrophy" (VVA) include vaginal dryness, burning, itching, vaginal discomfort and spotting. All these things affect women’s day to day life; also causing discomfort during sex since intercourse becomes more painful rather than pleasant [12]. This mostly happens during premenopause and menopause, but also if hormonal contraceptives (such as the pill) or antidepressants are taken.

8. Loss of libido

Hormonal imbalance can also lower your sex drive; the main reason behind this is the low levels of estrogen and testosterone. Between 20 and 40 years of age, the production of these sex hormones increases, but the production gradually decreases during perimenopause and menopause. Therefore, although it affects women of all ages, the loss of libido is particularly common in women going through the latter.

Learning to recognize early signs of possible hormonal imbalance is essential in order to know whether to solve the problem or whether it’s not necessary. Many women suffer from it and they aren’t aware that the source of the problem comes down to hormonal imbalance.

If you recognise these symptoms and think you have a hormonal imbalance, make sure you consult your doctor who will be able to tell you what tests to do and possible treatments to follow.
