More patients than ever are asking whether their hormones are behind their fatigue, anxiety, or low mood. Hormones can shape how we feel, but the evidence is more nuanced than the online claims suggest. At Carencia, we start with the whole person, not a target number on a lab report.

Fatigue. Irritability. Brain fog. Poor sleep. Anxiety. Low motivation. Changes in libido.

These are symptoms that show up often in our everyday lives. Now, more than ever, patients are asking whether their hormones may be responsible. The growing popularity of hormone replacement therapy (HRT) and testosterone replacement therapy (TRT) has created a wave of online claims suggesting that correcting a hormone level can resolve everything from depression to fatigue. At Carencia, we know that the conversation surrounding hormones deserves a more individual and tailored approach to care.

Quick Look: What This Article Covers

  • Hormones and the brain: estrogen, progesterone, testosterone, and their metabolites influence mood, sleep, cognition, and stress response.
  • Perimenopause: a period of higher depression risk, where the right answer may be estrogen, an SSRI, both, or neither.
  • Testosterone: a low level needs confirming with repeat morning testing, and TRT is not a replacement for depression treatment.
  • PMDD, postpartum, and DHEA: sensitivity to hormonal change can matter as much as the level itself.
  • Testing and treatment: labs should answer a clinical question, and hormone therapy is still medical therapy.

Hormones like estrogen, progesterone, testosterone, and their active metabolites can interact with many of the same systems involved in mood regulation, sleep, cognition, motivation, and stress response.

But, as with most areas of medicine, the evidence is more nuanced.

At Carencia, we believe hormone health and behavioral health should not exist in separate worlds. When clinically appropriate, evaluating hormonal labs can provide another piece of the puzzle. But hormone therapy should be based on symptoms, medical history, appropriate diagnostic evaluation, and current evidence rather than simply trying to achieve an “optimal” laboratory number. We are all more than a number on a piece of paper.

Why Hormones Matter to the Brain

Hormones do much more than regulate reproduction.

Estrogen, progesterone, testosterone, and their metabolites influence neural pathways involved in neurotransmitter activity, cognition, sleep, sexual function, and emotional regulation. This helps explain why certain periods of hormonal change can also become periods of mental and emotional vulnerability.

The issue is not always that someone has “too little” or “too much” of a particular hormone. For some patients, the change or fluctuation in hormones can be just as relevant.

That distinction matters.

The goal of evidence-based hormone management is not simply to increase hormone levels. It is to understand whether a patient’s symptoms, hormonal stage, medical conditions, medications, sleep, metabolic health, and psychiatric history fit together in a clinically meaningful way.

Perimenopause, Menopause, and Mental Health

Perimenopause is one of the clearest examples of the relationship between reproductive hormones and behavioral health.

During the menopausal transition, estrogen and progesterone levels can fluctuate substantially before eventually declining. Although hot flashes and menstrual changes receive much of the attention, patients may also experience changes in sleep, concentration, anxiety, irritability, and mood.

Recent evidence supports what many patients have been reporting for years: perimenopause can represent a period of increased vulnerability to depression. A 2024 systematic review and meta-analysis found that women in perimenopause had a significantly greater risk of depressive symptoms and diagnoses than premenopausal women (Badawy et al., 2024).

For appropriately selected patients, menopausal hormone therapy may improve vasomotor symptoms (hot flashes), sleep disruption, and other menopausal symptoms that can significantly affect mental well-being. Research also suggests that estrogen therapy may have modest antidepressant effects in some perimenopausal patients (Tseng et al., 2023; Xiang et al., 2024), although the evidence is not strong enough to consider HRT a universal treatment for depression. And, as always, your team at Carencia is here to discuss your options in a way that is unique to your healthcare journey and personal story.

This is an important distinction.

A patient experiencing a major depressive episode during perimenopause still deserves a comprehensive psychiatric evaluation. Psychotherapy, antidepressant treatment, lifestyle interventions, treatment of sleep disorders, and hormone therapy may all have roles in care depending on the individual.

In other words, sometimes the answer is estrogen. Sometimes it is an SSRI. Sometimes it is both. And sometimes neither addresses the actual underlying problem.

Testosterone: More Than Energy and Libido

Testosterone has received enormous attention in recent years, particularly through men’s health and direct-to-consumer clinics.

Low testosterone can be associated with decreased libido, reduced energy, changes in body composition, and mood symptoms. However, fatigue, poor motivation, low libido, and depressed mood are also extremely nonspecific symptoms.

Depression, obesity, sleep apnea, chronic illness, medication effects, substance use, chronic stress, and inadequate sleep can produce remarkably similar complaints.

For that reason, current endocrine recommendations emphasize diagnosing hypogonadism based on both compatible symptoms and consistently low testosterone levels, generally confirmed with repeat early-morning testing (Endocrine Society, 2026). A low (or borderline) number by itself does not automatically mean someone needs TRT. Conversely, a “normal” level may not mean that someone doesn’t need TRT.

When true hypogonadism is present, testosterone replacement may improve some aspects of well-being, particularly sexual symptoms. Research examining depression has found possible improvements in depressive symptoms in some populations, but testosterone should not be viewed as a replacement for established treatment of major depressive disorder.

From a behavioral health perspective, that means asking a broader question than simply, “Is the testosterone low?”

At Carencia, we also want to know why it might be low, and what else could be contributing to how this person feels.

Reproductive Hormones and Mood

Hormonal influences on mental health are not limited to menopause.

Some individuals appear particularly sensitive to reproductive hormonal transitions despite having hormone concentrations that would otherwise be considered physiologically normal.

Premenstrual Dysphoric Disorder (PMDD)

PMDD is an important example. PMDD is not simply the result of having an abnormal estrogen or progesterone level. Instead, susceptible individuals appear to experience an abnormal neurobehavioral response to normal hormonal changes across the menstrual cycle. That distinction changes treatment.

Rather than simply “replacing hormones,” evidence-based management may include SSRIs, certain combined hormonal contraceptives, psychotherapy, and lifestyle interventions. Current ACOG guidance recommends an individualized, multimodal approach (ACOG, 2023), and that is what Carencia does best.

The Postpartum Period

The postpartum period provides another example of the relationship between reproductive hormones and psychiatry. Following childbirth, reproductive hormones and neuroactive steroids change dramatically. Research involving the progesterone metabolite allopregnanolone and its effects on GABA-A receptors ultimately contributed to an entirely new class of treatments for postpartum depression (Dennis et al., 2024).

This development is an important reminder that reproductive psychiatry is not simply about “balancing hormones.” It is about understanding how hormonal transitions interact with the brain.

DHEA: The Precursor Hormone

Another important reproductive hormone is DHEA (dehydroepiandrosterone). Often described as the precursor to estrogen and testosterone, DHEA illustrates the connection between physical and behavioral health, and we know that it declines with age. Produced primarily by the adrenal glands, DHEA may influence mood, stress response, cognition, and sexual health.

At Carencia, DHEA can be considered alongside mood, sleep, metabolic health, reproductive status, medications, and other laboratory findings as we develop a care plan to help you feel your best. This is just another example of how our integrated approach allows us to look beyond a single symptom or lab value and treat the whole patient.

Hormone Testing: More Isn’t Always Better

One of the biggest misconceptions surrounding hormone care is that extensive laboratory panels can identify an ideal hormone level for every symptom.

Laboratory testing can absolutely be valuable, but only when the result answers a clinically meaningful question.

When a Lab Test Answers a Real Question

  • Testosterone: appropriately performed testing, with repeat early-morning samples, can help diagnose hypogonadism.
  • Thyroid: thyroid testing may identify a medical contributor to depression, anxiety, fatigue, or cognitive symptoms.
  • Other labs: further laboratory evaluation may be appropriate depending on symptoms and medical history.

Perimenopause is different.

Because reproductive hormone concentrations can fluctuate considerably during the menopausal transition, a single estrogen or follicle-stimulating hormone measurement may provide far less information than patients expect. Clinical history (including menstrual changes, vasomotor symptoms, sleep disruption, age, medications, and psychiatric history) often provides more meaningful context.

At Carencia, we believe laboratory values should support clinical decision-making, not replace it.

Hormone Therapy Is Still Medical Therapy

The increasing availability of online hormone clinics has sometimes created the impression that estrogen, progesterone, or testosterone are simply wellness products.

They aren’t.

These are biologically active medications with meaningful benefits, contraindications, interactions, and potential adverse effects.

Menopausal hormone therapy requires individualized assessment of factors such as age, time since menopause, uterine status, cardiovascular and thromboembolic risk, cancer history, symptoms, and treatment goals. Patients with a uterus receiving systemic estrogen generally require adequate endometrial protection with a progestogen.

Similarly, testosterone therapy requires appropriate diagnosis and frequent monitoring. Testosterone can increase hematocrit, affect fertility and spermatogenesis, and requires consideration of prostate health and other medical conditions.

Hormone management therefore works best when the goal is not simply more hormones, but the right treatment for the right patient. It is the same standard we apply to peptide therapy and every other treatment we offer.

Already on Hormone Therapy and Not Feeling Heard?

Some patients come to us already taking hormone therapy, started by another practice or an online service, and it may even be helping. But if the visits have gotten shorter, the lab work has stopped, or your questions have started to feel like interruptions, your instincts are worth trusting. Refilling a prescription is not the same as being cared for. Hormone therapy deserves ongoing attention, including periodic lab monitoring when indicated, reassessment of your dose and delivery method, and honest conversations about whether treatment is still meeting its goals. If you are already on HRT or TRT and wonder whether it is being monitored as closely as it should be, we are glad to take a careful look. Not to stop what works or start over, but to review your history, your current regimen, your labs, and your mental health together, and to make sure the plan still fits the person it was written for.

The Carencia Approach

At Carencia, we view hormonal assessment and management as one potential component of a broader treatment plan, not as a replacement for evidence-based psychiatric or medical care.

When symptoms suggest that hormonal factors may be contributing, evaluation can include:

What a Hormone Evaluation at Carencia Can Include

  • A detailed medical and psychiatric history
  • A medication review
  • Sleep and metabolic assessment
  • Reproductive or menopausal history, when applicable
  • Targeted laboratory testing
  • Discussion of evidence-based treatment options

When hormone therapy is appropriate, treatment should have a clear clinical indication, realistic goals, appropriate monitoring, and ongoing reassessment of both benefits and risks.

Just as important, we do not assume that every case of fatigue, anxiety, depression, brain fog, weight change, or low libido represents a hormone deficiency.

Sometimes hormones are an important part of the story. Sometimes they aren’t. Good medicine means being willing to investigate both possibilities. At Carencia, our goal is to understand the whole patient: their symptoms, medical history, behavioral health, sleep, metabolic health, medications, laboratory findings, and stage of life. Our functional medicine and primary care providers work alongside our psychiatric team, so no part of that picture gets looked at in isolation.

Hormone therapy may be one tool within that process.

And when it isn’t, identifying what is actually driving the symptoms is just as important.

Frequently Asked Questions

Can a hormone imbalance cause anxiety or depression?

It can contribute. Estrogen, progesterone, testosterone, and their metabolites interact with the same systems that regulate mood, sleep, cognition, and stress response, and periods of hormonal change can be periods of vulnerability. But fatigue, low mood, anxiety, and brain fog are nonspecific symptoms. Depression, sleep disorders, thyroid problems, medications, and chronic stress can produce the same complaints, so a comprehensive evaluation looks at all of them.

Does perimenopause increase the risk of depression?

Yes. A 2024 systematic review and meta-analysis found that women in perimenopause had a significantly higher risk of depressive symptoms and diagnoses than premenopausal women. Menopausal hormone therapy may help selected patients, and estrogen may have modest antidepressant effects for some, but it is not a universal treatment for depression. Sometimes the answer is estrogen, sometimes an SSRI, and sometimes both.

Will testosterone therapy fix my mood or energy?

Not on its own. Hypogonadism is diagnosed from compatible symptoms plus consistently low testosterone, usually confirmed with repeat early-morning testing. When true hypogonadism is present, testosterone replacement may improve some aspects of well-being, particularly sexual symptoms. It is not a replacement for established treatment of major depressive disorder, and a low number alone does not mean someone needs TRT.

Do I need a full hormone panel?

Not always. Testing is valuable when the result answers a clinically meaningful question, such as confirming low testosterone or checking thyroid function. During perimenopause, hormone levels fluctuate so much that a single estrogen or FSH measurement often tells us less than your clinical history does.

Is hormone therapy safe?

Estrogen, progesterone, and testosterone are biologically active medications with real benefits, contraindications, interactions, and potential side effects. Safe use means a clear clinical indication, an individualized assessment of factors like age, time since menopause, uterine status, cardiovascular and clotting risk, and cancer history, plus appropriate monitoring and ongoing reassessment.
