Why Your Hormones Are Out of Balance (And What to Do About It)

The Symptoms That Get Dismissed

You're tired all the time, even after a full night of sleep. Your weight is shifting in ways it never did before, despite no real change in diet or activity. Your mood fluctuates unpredictably. Your periods have become irregular, or more painful, or both. Your hair is thinning. Your libido has quietly disappeared.

You bring these to your doctor, labs come back "within normal range," and you're told it's probably stress. Or perimenopause. Or aging.

This is one of the most common stories I hear from women who find their way to functional medicine. The symptoms are real. The conventional workup often misses the nuance. And the consequences of leaving hormonal imbalances unaddressed extend far beyond quality of life — into cardiovascular health, bone density, cognitive function, and metabolic stability.

Hormones Are Not Isolated Variables

The conventional approach to hormonal health tends to be siloed. Thyroid goes to endocrinology. Mood goes to psychiatry. Weight goes to primary care. Periods go to gynecology. But the endocrine system is a finely tuned network — changes in one hormone cascade through the entire system.

Estrogen, progesterone, testosterone, cortisol, insulin, thyroid hormones, DHEA, and melatonin all influence each other through feedback loops. You cannot optimize one without understanding the others.

The Most Common Imbalances I See

Estrogen dominance is not simply high estrogen — it's the ratio of estrogen to progesterone. When progesterone is low (which happens throughout the luteal phase of cycles that don't ovulate properly, and accelerates in perimenopause), even normal estrogen levels can create dominance effects: heavy periods, bloating, breast tenderness, fibrocystic changes, and mood instability.

Subclinical hypothyroidism is extraordinarily common and routinely missed. Standard thyroid panels measure only TSH. A full thyroid panel — TSH, free T3, free T4, reverse T3, and thyroid antibodies — tells a completely different story for many patients. Women with Hashimoto's thyroiditis, an autoimmune condition, often have "normal" TSH while suffering significant symptoms because their T4 is not converting efficiently to active T3.

HPA axis dysregulation (what most people call "adrenal fatigue") reflects a cortisol rhythm that has become blunted or dysregulated from chronic stress. This affects energy, immune function, sleep architecture, and the production of downstream sex hormones — because when the body perceives ongoing threat, it deprioritizes reproductive hormones in favor of cortisol production.

Insulin resistance is a hormonal condition that amplifies estrogen dominance, drives ovarian cyst formation, disrupts the LH/FSH ratio, and contributes to the constellation of PCOS. It is also among the most reversible imbalances when caught early.

Why Conventional Testing Misses the Picture

Most conventional lab reference ranges are built on population statistics, not optimal function. A TSH of 3.5 is "normal" by most lab standards — but emerging research and functional medicine practice suggest that many patients feel best with levels closer to 1.0–2.0.

Beyond ranges, timing matters. Sex hormone levels fluctuate dramatically across the menstrual cycle. Testing estrogen and progesterone on a random day, without mapping where a patient is in her cycle, produces nearly meaningless data.

And urinary hormone metabolite testing — which shows not just hormone levels but how the body is clearing them — is rarely ordered in conventional settings, despite being clinically illuminating.

A Functional Medicine Approach

In my practice, a hormonal workup includes:

  • A comprehensive symptom and cycle history
  • Full thyroid panel (not just TSH)
  • Sex hormones timed to cycle phase (typically day 3 and day 19-22 in cycling women)
  • Fasting insulin and hemoglobin A1c alongside glucose
  • DHEA-S and cortisol (ideally 4-point salivary for rhythm assessment)
  • Urinary hormone metabolites when indicated (DUTCH test)
  • Micronutrient status, particularly vitamin D, magnesium, B vitamins, and iron

From this picture, we build an intervention strategy. This might include dietary changes to support estrogen metabolism, targeted supplementation, bioidentical hormone therapy when indicated, sleep optimization, and stress physiology work. Every protocol is matched to the individual — because no two hormonal patterns are identical.

What You Don't Have to Accept

Hormonal imbalance is not a normal part of aging. It is a treatable, often reversible condition — and the suffering that comes with it is not something you simply have to manage. If you've been dismissed with generic advice or a prescription for antidepressants when your intuition says something hormonal is wrong, trust that instinct.

You deserve a complete picture. That's what we build together.
