What Causes Hormonal Imbalance? 7 Factors That May Be Affecting Your Hormones

Hormonal symptoms can be frustrating because they don't always look like what we traditionally think of as a “hormone problem.”

Maybe your periods suddenly changed. You're waking up at 3 a.m. Your anxiety is worse. You're gaining weight differently, experiencing more PMS, feeling exhausted, having hot flashes, or noticing that your mood just isn't the same.

It's easy to assume that estrogen or progesterone must be the problem.

But hormones don't work in isolation.

Your reproductive hormones interact with your brain, thyroid, stress-response system, metabolism, insulin, sleep, nutrition, and stage of life. That's why figuring out what's contributing to your symptoms can be more complicated than simply checking one hormone level.

What Does “Hormonal Imbalance” Actually Mean?

“Hormonal imbalance” isn't one specific diagnosis.

Hormone levels naturally rise and fall throughout the menstrual cycle and change considerably during different stages of life, particularly pregnancy, postpartum, perimenopause, and menopause.

Symptoms commonly associated with hormonal changes can include:

• Irregular or changing periods

• PMS

• Breast tenderness

• Hot flashes or night sweats

• Difficulty sleeping

• Anxiety or mood changes

• Fatigue

• Changes in weight or body composition

• Difficulty concentrating or brain fog

• Headaches or migraines

• Acne

• Hair changes

• Low libido

• Fertility concerns

The tricky part is that many of these symptoms can also occur with thyroid disorders, blood sugar problems, nutrient deficiencies, chronic stress, poor sleep, certain medications, and other health conditions.

That's why I prefer to look at the whole picture rather than automatically assuming every symptom is caused by estrogen or progesterone.

1. Perimenopause and Menopause

For women in their late 30s, 40s, and early 50s, this is one of the first things I consider.

Perimenopause can begin years before your periods stop completely.

During this transition, estrogen doesn't simply decline in a nice, predictable line.

Hormone levels can fluctuate, while progesterone may also change as ovulation becomes less consistent.

That's why one month you may feel completely normal and the next month feel like your body has suddenly changed.

Symptoms can include changes in your menstrual cycle, increased PMS, anxiety, sleep problems, hot flashes, night sweats, headaches, brain fog, fatigue, and changes in body composition.

And yes—you can still have regular periods and be in perimenopause.

Understanding the stage of life you're in is an important part of understanding what's happening hormonally.

2. Chronic Stress

Stress and hormones are closely connected.

Your hypothalamic-pituitary-adrenal (HPA) axis helps coordinate your body's response to stress and regulates cortisol.

Short periods of stress are normal. The problem is when your body rarely gets a chance to come out of that stress response.

Poor sleep, emotional stress, overtraining, under-eating, illness, work stress, caregiving, and simply doing too much for too long can all add to your overall stress load.

You may notice:

• Feeling tired but wired

• Difficulty falling or staying asleep

• Increased anxiety

• Changes in appetite

• Low libido

• Fatigue

• Difficulty concentrating

• Feeling less resilient to everyday stress

I used to see the term “adrenal fatigue” used frequently to describe this collection of symptoms. Today, I prefer talking about stress physiology and HPA-axis function, because the adrenal glands don't simply become “exhausted.”

The symptoms are still very real. We just need to be more accurate about what's happening physiologically.

3. Thyroid Function

Your thyroid has an enormous influence on how you feel.

Thyroid hormones are involved in metabolism, energy, body temperature, digestion, heart rate, menstrual function, and many other processes.

Symptoms associated with an underactive thyroid can include fatigue, feeling cold, constipation, dry skin, hair changes, difficulty concentrating, menstrual changes, and changes in weight.

Notice how much overlap there is with symptoms women often attribute to hormonal imbalance or perimenopause?

That's why thyroid function can be important to evaluate when the symptoms and health history point in that direction.

And rather than assuming every thyroid symptom requires an enormous panel of testing, I prefer choosing laboratory testing based on the individual patient's history, symptoms, previous results, and clinical picture.

4. Blood Sugar and Insulin

This is one of the pieces of hormonal health that doesn't get enough attention.

Insulin is a hormone too.

What you eat, how frequently you eat, your muscle mass, activity level, sleep, genetics, and metabolic health can all influence blood sugar regulation and insulin sensitivity.

Blood sugar fluctuations can also affect how you feel throughout the day.

Some people notice:

• Energy crashes

• Strong sugar or carbohydrate cravings

• Feeling shaky or irritable when hungry

• Increased hunger

• Fatigue after meals

• Changes in body composition

Insulin resistance is also closely associated with conditions such as PCOS, where reproductive and metabolic hormones can both be involved.

This is one reason nutrition and strength training can be such important parts of women's hormonal health.

5. Sleep

We tend to think of poor sleep as a symptom of hormonal changes, but the relationship goes both ways.

Your sleep and circadian rhythm interact with cortisol, insulin sensitivity, appetite-regulating hormones, and reproductive health.

And during perimenopause, it can become a frustrating cycle:

Hormonal fluctuations disrupt sleep → you're exhausted the next day → stress tolerance decreases → cravings and appetite change → you feel even worse → and then you don't sleep well again.

This is why improving sleep is often one of my priorities when working with women experiencing hormonal symptoms.

Sometimes we don't need another “hormone-balancing” supplement.

We need to figure out why you're waking up every night.

6. Nutrition and Nutrient Status

Your body needs adequate energy, protein, healthy fats, vitamins, and minerals to function normally.

Extremely restrictive dieting, chronically under-eating, nutrient deficiencies, or losing weight too rapidly can affect reproductive function and menstrual cycles.

Nutrition can also indirectly influence hormonal health through blood sugar regulation, digestion, metabolic health, and overall energy availability.

That doesn't mean there's one magical “hormone-balancing diet.”

There isn't.

I prefer building nutrition around the individual woman—her stage of life, activity level, symptoms, metabolic health, digestion, and goals.

7. Medications and Hormonal Contraceptives

Certain medications can influence hormones or produce symptoms that overlap with hormonal changes.

Hormonal contraceptives intentionally alter reproductive hormone signaling to prevent pregnancy and may also be prescribed for concerns such as painful periods, heavy bleeding, acne, endometriosis, or PCOS.

Some women experience side effects, while others do very well on them.

I would not say that birth control permanently “shuts down” your body's ability to make progesterone or that hormonal contraceptives are inherently a major cause of hormonal imbalance.

Instead, your medication and contraceptive history is simply one piece of information that should be considered when evaluating symptoms.

If you think a medication is contributing to how you feel, talk with the prescribing clinician rather than stopping it on your own.

What About the Liver and Hormones?

Your liver absolutely plays a role in hormone metabolism.

It helps metabolize and process many substances in the body, including steroid hormones. But I don't like describing the liver as “sluggish” or saying that you need to detox your liver to balance estrogen.

For most people, your liver is already doing its detoxification work every day.

Supporting overall liver and metabolic health means focusing on the fundamentals:

balanced nutrition, appropriate exercise, limiting excessive alcohol, maintaining metabolic health, getting adequate sleep, and addressing actual liver disease when present.

The Chinese Medicine Perspective Is Different

This is where terminology can get confusing.

In Chinese medicine, when I talk about Liver Qi stagnation, I'm not diagnosing a diseased or poorly functioning anatomical liver.

“Liver” in Chinese medicine describes a traditional functional system and pattern of signs and symptoms.

For example, a woman experiencing irritability, breast tenderness, PMS, bloating, headaches, and emotional changes may fit a pattern involving Liver Qi stagnation.

Another woman with hormonal symptoms may show signs of Kidney Yin deficiency, Kidney Yang deficiency, Spleen Qi deficiency, Blood deficiency, or a combination of patterns.

That's why Chinese medicine treatment is individualized.

Why Can My Hormone Tests Be “Normal” When I Don't Feel Normal?

I hear this frequently.

First, a normal laboratory result doesn't mean your symptoms aren't real.

But it also doesn't automatically mean conventional testing “missed” a hormonal imbalance.

Hormone levels can vary with age, menstrual-cycle timing, medications, and the particular hormone being measured. And sometimes the symptoms aren't primarily being caused by reproductive hormones at all.

Sleep problems, thyroid disorders, anemia or nutrient deficiencies, metabolic issues, medication effects, mood disorders, and other medical conditions can produce overlapping symptoms.

The goal shouldn't be to keep testing until we find an abnormal number.

The goal should be to use your symptoms, history, physical evaluation, and appropriate testing together to understand what deserves attention.

Do You Need Hormone Testing?

Sometimes.

But not every woman experiencing hormonal symptoms needs every hormone tested.

Testing should answer a clinical question.

Depending on your age, symptoms, menstrual cycle, medical history, and medications, appropriate evaluation might include thyroid testing, metabolic markers, nutrient-related testing, reproductive hormones, or other labs.

And in perimenopause specifically, one hormone test doesn't always tell the whole story because hormone levels can fluctuate significantly.

Testing is a tool—not the entire diagnosis.

💡 Dr. Stephanie's Tip: Don't assume that every symptom after 40 means your estrogen is low—or that you need a cabinet full of “hormone-balancing” supplements.

Start with the bigger picture.

Look at your menstrual cycle, sleep, stress, nutrition, thyroid health, blood sugar, exercise, medications, and stage of life. Sometimes the clue isn't one abnormal hormone. It's the pattern created by several things happening at the same time.

A More Personalized Approach to Hormonal Health

If you're experiencing changes in your periods, sleep, mood, energy, weight, temperature, or overall sense of well-being, you deserve a more thoughtful approach than simply being told that everything is “normal.”

At New Direction Natural Medicine in Altamonte Springs, FL, I combine functional medicine with acupuncture, Chinese medicine, nutrition, and Chinese herbal medicine when appropriate.

The goal isn't to blame every symptom on hormones—or chase every lab value.

It's to understand your symptoms in context and create a treatment plan based on you.

If you're struggling with hormonal symptoms, perimenopause, or simply don't feel like yourself anymore, schedule a consultation and let's take a closer look at the bigger picture.
