Hormonal Imbalance Symptoms: A Starting Point, Not a Diagnosis
A map of which symptoms point toward which hormone system, what overlaps with what, and why the pattern matters more than the checklist.
Somebody arrives with a list. Tired in a way sleep does not fix, foggy, cycles that have gone strange, weight that will not move, mood that is not theirs. They have been told it is stress, or age, or that their labs are normal. They want to know which hormone it is.
This page is the honest version of that answer. It is a map of which symptoms point toward which system, and it is deliberately not a quiz with a result at the end.
Two things before the lists
Hormonal imbalance is not a medical diagnosis. There is no test for it. What exists is specific hormones measurably too high or too low, each with its own test and its own treatment. I use the phrase here because it is the one people search with, not because it means something on its own.
Almost every symptom below appears in several places. Fatigue is on most of these lists. So is brain fog, so is weight change, so is low mood. That is not sloppiness, it is the actual biology: these systems interact, and they also overlap with things that are not hormonal at all, including anaemia, sleep apnoea, depression, coeliac disease and simply not sleeping enough.
Which means a symptom list cannot diagnose you and this one is not trying to. It can tell you which direction to look, and what to ask for.
Estrogen
When it is low: hot flushes, night sweats, irregular or absent cycles, vaginal dryness and painful intercourse, recurrent urinary tract infections, fatigue, brain fog, low mood, headaches, sleep disruption.
When it is high relative to progesterone: breast tenderness, bloating and water retention, heavy periods, headaches, anxiety, low libido, weight gain around the middle.
Low estrogen is the perimenopausal and menopausal picture, and it also appears with significant underweight or very high training volume. The metabolic side of that transition, which gets missed most often, is in the perimenopause metabolic shift.
On "estrogen dominance". You will see the term everywhere. It describes a real idea, estrogen high relative to progesterone rather than high in absolute terms, and it has no agreed clinical definition and no test that establishes it. What can be measured is estradiol, progesterone and where you are in your cycle. I am not dismissing what people mean by it. I am saying that a saliva panel claiming to diagnose it is selling you something.
Progesterone
When it is low: irregular cycles, spotting between periods, difficulty conceiving, poor sleep and insomnia, anxiety, mood changes before the period, headaches, hot flushes.
When it is high: usually in the luteal phase or in pregnancy, breast swelling and tenderness, bloating, fluid retention, fatigue, low mood, irritability.
Progesterone has to be measured at the right point in the cycle or the result means nothing, which is the most common reason a woman is told hers is fine when it has not actually been assessed.
Testosterone, in women
When it is high: acne along the jaw and chin, oily skin, hair growth on the face, chest or abdomen, thinning hair at the temples, irregular or absent cycles, difficulty conceiving, mood changes.
When it is low: low libido, fatigue, brain fog, muscle weakness, low mood.
High androgens in a woman with irregular cycles is the polycystic ovary syndrome picture, and the driver underneath is usually insulin: PCOS is a metabolic condition that happens to affect ovaries. Low testosterone in women is real, underinvestigated and covered in testosterone is not only a men's hormone.
Thyroid
Underactive, hypothyroidism: fatigue, cold sensitivity, weight gain and fluid retention, constipation, dry skin, hair loss, brittle nails, low mood, slowed thinking, heavy periods, facial and periorbital puffiness. The full picture is in hypothyroidism symptoms.
Overactive, hyperthyroidism: weight loss, heat intolerance, sweating, tremor, palpitations or a fast or irregular heartbeat, anxiety and nervousness, irritability, more frequent bowel movements, difficulty sleeping.
Thyroid is where the most testing goes wrong, because TSH alone is frequently the only thing ordered and it is not sufficient to characterise the problem: TSH alone is not a thyroid panel. If you are treated and still feel unwell, that is a known situation with known causes, in you are on thyroid medication and you still feel off. And not every underactive thyroid has the same cause: two people, the same thyroid number, two different diseases.
Cortisol
When it is persistently high: weight gain centrally, sugar cravings, disturbed sleep, feeling tired but wired, mood changes, raised blood pressure and glucose, and in genuine cortisol excess a characteristic rounding of the face, easy bruising and purple stretch marks.
When it is low: profound fatigue, low blood pressure, dizziness on standing, nausea, low blood sugar, salt craving, weight loss, darkening of the skin.
Two things need saying clearly here.
Adrenal insufficiency is a real diagnosis and it is an emergency when it decompensates. Untreated adrenal crisis can be fatal. If you have severe weakness, vomiting, abdominal pain, confusion or collapse, particularly if you take or have recently stopped steroid medication, that is an emergency department, not a clinic appointment, and not a page on the internet.
"Adrenal fatigue" is not that condition and is not a recognised diagnosis. Being exhausted by a sustained period of stress is real and common. It is not a cortisol deficiency, and the supplement protocols sold for it treat a diagnosis you do not have. The actual effects of sustained high cortisol on metabolism are in high cortisol is a metabolic blocker.
Insulin
When insulin is high and cells are resistant to it: weight that accumulates around the middle and resists what used to work, energy crashes after meals, hunger returning quickly, cravings after eating, darkened velvety skin at the neck or armpits, skin tags, and in women irregular cycles and androgen symptoms. Later, as glucose rises: increased thirst, frequent urination, frequent infections, tingling in hands and feet.
This is the one most likely to be present while every standard test comes back normal, because glucose stays in range for years while insulin climbs. What is happening at the cellular level is in why your cells stopped listening to insulin, and the timeline in the ten years before anyone says the word diabetes.
Why so many of these look the same
Because the systems are not independent. Sustained cortisol works against insulin and suppresses the conversion of thyroid hormone into its active form. High insulin raises ovarian androgens. Falling estrogen reduces insulin sensitivity. An untreated thyroid makes insulin resistance worse.
So a person can have one primary problem and symptoms from three systems, and they will be told each one separately looks minor. The order in which to untangle that is in the four hormonal systems that decide metabolic progress.
What to do with this page
Do not count your symptoms and conclude something. Use it to ask a better question.
Take the pattern rather than the individual items. Note when it started and what changed around then. Note where you are in your cycle if you have one. And ask for the test that looks at the system the pattern points to, rather than the general panel that will come back normal.
If it has already come back normal and you still feel unwell, that is a specific situation with specific causes, and it is the single most common reason people end up in my office: your labs came back normal, so why do you still feel unwell.
Symptoms overlap. That is the honest headline on a page like this, and it is why the list is a starting point for a conversation rather than the end of one.
