GLP-1 Medications and Perimenopause: Why Weight Changes After 40 and What Helps
Weight gain in perimenopause is driven by estrogen decline and a shift in how the body stores fat, not just calorie intake. GLP-1 medications address the appetite and metabolic piece that diet and exercise alone often can't reach during this transition.

What Nobody Told You About Perimenopause
Hot Flashes Treatment: What Works and What the Research Shows

Low Sex Drive During Menopause: Why It Happens and What Works
Low desire is one of the most common sexual health changes of menopause, and it tends to get dismissed as inevitable. Hormones are part of the picture, but desire runs on its own brain pathway that estrogen alone doesn't always reach. Both pieces have medical options.
Perimenopause Belly Fat: What HRT Alone Doesn't Fix
You started HRT a year ago. The hot flashes went away. The mood is steadier. The sleep is much better. The belly fat that showed up around 44 is still there, and looked at squarely, it might even be slightly worse. Here's why HRT alone often doesn't address this specific problem.
NAD+ and Perimenopause: Why You're Still Tired After HRT
Perimenopause is a hormonal transition. But the fatigue that comes with it has a second driver, NAD+ levels fall faster in your 40s than age alone predicts, because estrogen is part of what keeps NAD+ production running. Here's how the two declines interact and why some women add NAD+ to their HRT regimen.
The 3 AM Wake-Up Club: What Perimenopause Does to Your Cortisol

Perimenopause Sleep: Why It Breaks at 42 and What's Actually Helping
Sleep disruption is one of the most common complaints in perimenopause, and the mechanism is more specific than 'hormones.' Progesterone decline removes GABA-ergic calm. Estrogen fluctuation disrupts temperature regulation. Cortisol shifts change the architecture of early-morning waking.
