Women’s Health After 40: The New Rules for Healthy Aging

Turning 40 is a big milestone — especially when it comes to your health. As you enter perimenopause, typically in your mid-40s, estrogen levels fluctuate and naturally decline. 

Estrogen helps reduce inflammation and protects vital systems.“As estrogen levels drop, bone and muscle loss tend to accelerate,” says OB-GYN Kanchi Chadha, M.D. “We also see changes in cholesterol, blood pressure and metabolic health, which can elevate your risk for osteoporosis, diabetes and heart disease.”

The good news is that there are steps you can take now to protect your health in the future. 

“It’s about taking care of the systems that determine how well you’re going to function decades from now,” Dr. Chadha says.

Here, Dr. Chadha and primary care physician Armida Priftani, M.D., who both lead Hackensack Meridian Health’s new Women’s Midlife Health and Longevity Program, provide your playbook for healthy aging after 40.

The New Rules for Healthy Aging After 40

1. Know Your Numbers

Keep track of your blood pressure, cholesterol, blood sugar and weight. As the protective effects of estrogen start to diminish, risk to your heart health rises sharply, Dr. Chadha says.

At your next appointment, ask your doctor if you’re up to date on cholesterol and diabetes screenings based on your individual risk factors.

2. Mind Your Muscles

Most women lose a significant amount of muscle during perimenopause and menopause, Dr. Priftani says. 

To maintain as much muscle as possible, aim to do resistance training two to three times a week. “Even if it’s short sessions using body weight, resistance bands or weights, it can be very meaningful,” says Dr. Chadha.

3. Bone Up

Estrogen protects your bones. As it declines, bone loss speeds up, Dr. Chadha says. Weight-bearing and resistance exercise, plus getting enough calcium and vitamin D can help. 

If joint pain rules out harder workouts, try beginner tai chi classes, Dr. Priftani says. 

Wondering about your fracture risk? Ask your doctor about getting a bone density (DEXA) scan.

4. Rethink Your Plate

After 40, your body doesn’t process cholesterol and carbs the way it used to, so weight gain is common, even if your eating habits haven’t changed, says Dr. Priftani. 

Her advice: Prioritize protein and fiber from fruits and vegetables and eat fewer processed carbs.

5. Make Sleep a Priority

Poor sleep raises the stress hormone cortisol, which can contribute to weight gain, Dr. Priftani says. 

To improve your sleep, keep a consistent sleep and wake schedule, stop eating two to three hours before bed, and skip late workouts. If that doesn’t help, ask your doctor about taking a magnesium supplement, seeing a sleep specialist or pursuing cognitive behavioral therapy for insomnia.

6. Pay Attention to Your Mental Health

Anxiety and depression are common in midlife, Dr. Priftani says. Perhaps because hormonal changes, caregiving and career pressure often peak together, notes Dr. Chadha. 

Give your emotional health the same attention you give your physical health. If anxiety, depression, irritability or a loss of enjoyment persists and disrupts daily life, reach out to your doctor.

7. Ask If Hormone Therapy Is Right for You

Menopause hormone therapy (MHT) is mainly used to treat hot flashes and night sweats, vaginal dryness, urinary symptoms and to prevent bone loss, Dr. Chadha says. 

If you’re experiencing these symptoms, ask your doctor if you’re a candidate. Hormonal and nonhormonal treatments are available. 

Why Your Doctors Should Work Together

“When care is not coordinated, women end up seeing multiple specialists and having each symptom evaluated separately; the patient is then left to connect these dots,” says Dr. Chadha.

The Women’s Midlife Health and Longevity Program makes those connections. Make your first appointment with: Dr. Priftani, who focuses on cardiac and metabolic health as well as autoimmune and sleep and mood disorders, or Dr. Chadha, who focuses on individualized hormonal and nonhormonal treatment plans as well as dietary and lifestyle interventions to optimize health and wellbeing during the menopause transition.

When to Talk to Your Doctor

Any new, persistent, worsening or disruptive symptom is worth a visit. “The first thing the patient will tell me: ‘I don’t feel like myself,’” says Dr. Priftani. That includes irregular periods, hot flashes, brain fog and low sex drive.

Chest pain, significant shortness of breath, fainting, sudden numbness or unusually heavy bleeding shouldn’t wait; get prompt care. 

As Dr. Chadha says, “The 40s are really an opportunity to understand your health risks, establish healthy habits, address symptoms early and create a long-term plan with your doctor.”
