Our videos to understand your health
Clear explanations, with their medical sources cited. Videos are in French, with English subtitles available.
Bloating, reflux, transit: what really changes in your belly
In the morning your trousers close, in the evening they do not. This is not fat: fat does not appear in ten hours. What perimenopause really changes about digestion, and why what gets worse later is the pelvic floor, not the gut. In French with English subtitles.
Video pageIs your body inflamed at menopause? What is true
Low-grade chronic inflammation does rise around the final period, but not in every woman, and it does not explain hot flashes. What food really changes for bones, weight and mood, with the exact size of the effects. In French with English subtitles.
Read the full articleVery heavy periods: this is not just your age
Why periods become endless and heavy in perimenopause, and why it is not a lack of estrogen but an absence of progesterone. The iron nobody thinks to measure, and the signs that mean seeing a doctor without waiting. In French with English subtitles.
Read the full articleThyroid or menopause? The signs that actually tell them apart
You feel cold when nobody else does, and at 50 you are told it is the menopause. Maybe. Or maybe the thyroid: the signs that really point one way, how TSH settles it, and why finding something is not the same as finding the cause. In French with English subtitles.

Frequently asked questions
Short answers, grounded in the studies. To go further, our articles and videos.
At what age does perimenopause start?
Perimenopause usually begins between 40 and 45, sometimes earlier. It lasts on average 4 to 8 years before menopause (12 consecutive months without a period). First signs: irregular cycles, disturbed sleep, mood swings. Take the Menopause Test to identify your stage.
Why am I gaining weight in menopause despite eating healthily?
The drop in estrogen redistributes fat toward the abdomen, muscle mass decreases (metabolism slows down) and cortisol promotes abdominal storage. It is not a lack of willpower: it is hormonal, and validated strategies exist. Read our cortisol & weight guide.
Is brain fog in menopause normal?
Yes, it is a frequent, documented symptom: estrogen is fuel for the brain, and its decline temporarily affects memory and concentration. The phenomenon usually improves in postmenopause. Understanding brain fog.
Are phytoestrogens (soy, flax) effective against symptoms?
Clinical studies show a modest but real effect in some women, particularly on hot flashes. The effect varies with the gut microbiome. The complete phytoestrogen guide.
Is intermittent fasting suitable for women over 45?
The female body responds differently to energy deficit: overly aggressive fasting can stress the hormones (cortisol, thyroid). Studies suggest gentle windows (12 to 14 h) and a gradual approach. Watch the intermittent fasting video.
Is menopause hormone therapy (MHT) dangerous?
Recent data are more reassuring than its reputation: for most women under 60, within 10 years of menopause, the benefits often outweigh the risks. The decision is made with a doctor. What the studies say about hormone therapy.
