Now that you’re in your late 30s or early 40s, do you occasionally feel like your premenstrual cramps and PMS mood swings have sidelined you a bit more?

Bonafide Chief Medical Officer, Dr. Alyssa Dweck confirms it: PMS can become worse with age. Here, she weighs in on why PMS can feel different in your 30s and 40s and what changes you could potentially expect with your menstrual cycles as menopause draws near.

Is Your PMS Getting Worse with Age?

PMS, or premenstrual syndrome, refers to the symptoms many women experience in the 2 weeks leading up to their period.¹ PMS symptoms can range in both type and severity, but may include: ²

Irritability
Mood changes
Trouble sleeping
Fatigue
Decreased Libido
Food Cravings and Appetite Changes
Breast Tenderness
Bloating
Changes in Digestion
Abdominal Cramps

Many women may find that these symptoms—and others—can worsen as they approach the menopause transition, or the 2-10 years leading up to menopause where hormones, estrogen and progesterone, are volatile and then significantly decline.^3,4 Mood changes may become less predictable, flow may increase, and fatigue may reach disruptive new levels.

In other words, the body is preparing to no longer have periods—and it’s no surprise you’re feeling it.

“Predictable cycles with regular hormone peaks and valleys mean a more predictable timing and resolution of these symptoms,” Dr. Dweck explains. “Fluctuating estradiol and progesterone levels— more commonly experienced during a woman's late 30s and 40s during the perimenopause years—can intensify premenstrual syndrome symptoms.”⁵

What Causes Worsening PMS in Midlife?

While women may anticipate less frequent periods leading up to menopause, many women in midlife may actually experience the opposite. As cycles shorten or shift, periods—and the associated PMS symptoms—may be more frequent and severe.⁶

So, what exactly causes these more severe perimenopause PMS symptoms? According to Dr. Dweck, shifting hormones.

“Symptoms of premenstrual syndrome (PMS), including specific food cravings and increases in appetite, can intensify during perimenopause due to hormonal volatility, specifically estradiol and progesterone,” she explains. “The irregularity of the cycle during perimenopause only makes these symptoms worse because they are often unpredictable and unanticipated.”
