Periods often get heavier in perimenopause, not lighter. As ovulation turns patchy, cycles can make oestrogen with little progesterone to thin the lining, so it builds unopposed and the next bleed runs heavy. Usually hormonal, but very heavy bleeding is worth getting checked.

[The Hormone Blueprint @mvideika1]

@_CynthiaThurlow The piece that keeps it missed: perimenopause is driven by oestrogen swinging, not steadily falling. Levels can test normal on the wrong day, so women are told they are fine while the volatility itself drives the sleep, mood and cycle chaos. Treat the pattern, not one number.

@hormonedietdoc A mechanism worth naming here: the cephalic phase. The sight and smell of food should trigger the vagus to prime stomach acid and pancreatic enzymes before the first bite. Eat in fight-or-flight and that priming never fires, so you under-secrete and absorb less of a good meal.

@VikramSinai A tell that spares needless workup: menopausal arthralgia is often symmetrical, worse on waking and migratory, but without the swelling, raised CRP or erosions of inflammatory arthritis. Oestrogen receptors sit in cartilage and synovium, so bloods read clean while joints hurt.

Taking testosterone can quietly switch off the sperm you make.
Exogenous T tells the brain to stop sending LH and FSH, so the testes wind down. Men who start TRT expecting a fertility boost can get the opposite.
If children might be on the cards, ask about that before you start.

[The Hormone Blueprint @mvideika1]

@ThatPHCBoy One precise tweak: it's actually oestrogen, not testosterone directly, that fuses the growth plates. The body makes it by aromatising testosterone, so with none before puberty there's nothing to convert, the plates never close, and the long bones keep going.

Sudden dizziness in perimenopause often gets filed under anxiety. But the inner ear is an oestrogen-sensitive organ: the tiny calcium crystals that sense head position depend on it, and as levels fall they can destabilise. It's why positional vertigo spikes around menopause.

[The Hormone Blueprint @mvideika1]

@ElieJarrougeMD A hormone loop sits on top of this: insulin resistance drags testosterone down — partly via lower SHBG, partly at the testis. Low T then makes muscle harder to hold, shrinking the glucose sink further. Muscle isn't just storage — it's an endocrine organ.

[The Hormone Blueprint @mvideika1]

@hormonedietdoc The same trap runs through sex hormones — SHBG is the transporter there, and oestrogen raises it too. So the pill, HRT or pregnancy inflate total testosterone while the free, active fraction barely shifts. It's why the free number, not the total, is the one worth reading.

[The Hormone Blueprint @mvideika1]

Testosterone doesn't make you go bald. DHT does — and only in scalp follicles that are genetically sensitive to it.

The same hormone thickens your beard and thins your crown, depending on the receptor. Which is why plenty of high-T men keep their hair, and low-T men lose it.

[The Hormone Blueprint @mvideika1]

@VikramSinai The part that gets lost once treatment ends: a 25-year-old pushed into menopause loses decades of oestrogen, not a few years — a real hit to bone and vascular risk. Yet these young survivors are often the least likely to be offered HRT, on cancer fears that rarely apply to them.

[The Hormone Blueprint @mvideika1]

@hormonedietdoc Olive oil earns its spot hormonally, not just as anti-inflammatory garnish. Its polyphenols — oleocanthal, hydroxytyrosol — seem to nudge aromatase down a touch and cut the oxidised LDL that drags testosterone with it. A small androgen lever on top of the polyphenol story.

[The Hormone Blueprint @mvideika1]

@iam_preethi There's a hormone angle here: thyroid status gates that conversion too. An underactive thyroid slows beta-carotene to retinol — which is why some hypothyroid women get faintly orange palms while genuinely low on true vitamin A. A BCMO1 variant and a sluggish thyroid can stack.

[The Hormone Blueprint @mvideika1]

Restless legs that flare in perimenopause aren't 'just stress'. Low brain iron is the classic driver of that crawling urge to move, and oestrogen swings shift how the brain uses dopamine. Which is why checking ferritin — not just a normal blood count — often settles it.

[The Hormone Blueprint @mvideika1]

In men, belly fat isn't only a symptom of low testosterone — it's a cause.

Fat carries aromatase, the enzyme that turns testosterone into oestrogen. More fat, more conversion, less usable T, which lays down more fat.

A loop — and the way out is often the waist, not a script.

[The Hormone Blueprint @mvideika1]

@hormonedietdoc The hormone tie-in people miss: copper and zinc see-saw against each other, and zinc drives testosterone synthesis. So chasing T with high-dose zinc can quietly tank copper. Oestrogen also raises serum copper — one reason it reads high on the pill or in pregnancy.

[The Hormone Blueprint @mvideika1]

@iam_preethi The mechanism is real: high insulin pushes the ovary to make more testosterone and lowers SHBG, so more runs free. Drop the insulin and it reverses. Though PCOS isn't one thing — the lean, adrenal-driven type responds far less, often why 'tried everything' feels true.

[The Hormone Blueprint @mvideika1]

@_CynthiaThurlow The bit that compounds it: much of women's ischaemia is microvascular, so the arteries look 'clean' on an angiogram and she's sent home reassured. Add the oestrogen drop at menopause stiffening vessels and shifting lipids, and a male-pattern workup misses her twice.

[The Hormone Blueprint @mvideika1]

@iam_preethi Brilliant list. One piece to add at 65 months of lactation: sustained nursing keeps prolactin high, which suppresses the ovarian axis — so low oestrogen can quietly hit bone, libido and mood while feeds continue. It eases as nursing tapers, but it's the axis, not a failing.

[The Hormone Blueprint @mvideika1]

@hormonedietdoc Agree on the sequencing — I'd add one tier above supplements: the hormonal set-point. In midlife, what won't budge on a clean diet and solid basics is often falling thyroid, testosterone or oestrogen resetting the ceiling, not a nutrient gap. Test the axis first.
