Birth Control, Perimenopause, or Both? How One Woman Reclaimed Her Hormonal Health Through an Individualized Treatment Plan

US Women’s Medical Center

“I Felt Like I Was Aging Overnight”

A 40-year-old woman came to US Women’s Medical Center searching for answers.

Over the previous year, she felt like her body had changed dramatically.

Despite eating well, exercising regularly, and making an effort to prioritize her health, she continued to struggle with symptoms that seemed to worsen month after month.

She reported:

Weight gain despite healthy habits
Brain fog
Irritability and mood changes
Night sweats
Poor sleep quality
Fatigue
Low libido
Vaginal dryness

Like many women entering their 40s, she began wondering whether this was simply a normal part of aging.

What she didn’t realize was that multiple hormonal factors could be contributing to her symptoms simultaneously.

A Long History of Hormonal Birth Control

During her consultation, she shared that she had been taking hormonal birth control since her teenage years.

More recently, she had developed breakthrough bleeding and was switched to a progesterone-only birth control pill (Norethindrone) due to adenomyosis.

Shortly after the switch, many of her symptoms either appeared for the first time or became significantly worse.

She described feeling unlike herself.

Her energy levels had declined. Sleep quality had deteriorated. Brain fog was becoming more frequent. Her libido had noticeably decreased, and she was experiencing regular night sweats.

At that point, a comprehensive hormone evaluation was ordered.

Initial Hormone Testing Revealed Significant Suppression

Laboratory testing revealed remarkably low hormone levels.

Initial Hormone Results

Estradiol: 8 pg/mL

Progesterone: less than 0.5 ng/mL

Testosterone: 9 ng/dL

These values closely aligned with the symptoms she was experiencing.

Many women assume birth control is “balancing hormones,” but hormonal contraceptives work by suppressing the body’s natural hormone production.

For women entering perimenopause, this can sometimes make an already complex hormonal transition even more difficult to evaluate.

The Most Important Question

At this point, we needed to determine what was truly causing her symptoms.

Were they caused by:

Perimenopause?
Hormonal birth control?
Natural ovarian decline?
Or some combination of all three?

Instead of immediately prescribing hormone replacement therapy, we chose a more conservative approach.

We wanted to understand what her body was capable of producing on its own.

The patient discontinued her progesterone-only birth control pill.

Our plan was to:

Allow natural hormone production to recover
Wait for menstrual cycles to return
Reevaluate hormone levels after several cycles
Create a treatment plan based on her body’s actual hormone production

This step proved critical.

Three Months Later: Her Body Started Recovering

Approximately three months after discontinuing birth control, her menstrual cycles returned.

While she still experienced symptoms, repeat laboratory testing told a very different story.

Hormone Levels After Stopping Birth Control

Estradiol: increased from 8 pg/mL to 66 pg/mL

Progesterone: increased from less than 0.5 ng/mL to 4.8 ng/mL

Testosterone: increased from 9 ng/dL to 15 ng/dL

These results demonstrated that her ovaries were still functioning.

Her estrogen level increased more than eightfold.

Progesterone production resumed.

Testosterone improved modestly.

The suppression caused by hormonal birth control had clearly played a role.

However, the story wasn’t over.

Why Symptoms Persisted

Although her hormone levels improved, she still reported:

Brain fog
Insomnia
Night sweats
Bloating
Low libido

Her menstrual cycles had returned but often lasted nearly two weeks.

This is a common presentation during perimenopause.

The ovaries are producing hormones, but often not enough to fully eliminate symptoms.

Simply restoring natural hormone production isn’t always sufficient.

Sometimes the body needs additional support.

A Conservative Hormone Therapy Approach

Because she was only 40 years old and still cycling naturally, we opted for a low-dose bioidentical hormone replacement therapy protocol.

The goal was not to replace large amounts of hormones.

The goal was to support declining hormone production while preserving normal ovarian function.

Her treatment plan included:

Bioidentical Hormone Therapy

Bi-Est 50/50: 0.0375 mg twice daily

Testosterone: 1 mg twice daily

Micronized Progesterone: 200 mg nightly

This individualized approach allowed us to address symptoms while respecting her body’s ongoing hormone production.

Three Months Later: A Remarkable Improvement

When she returned for follow-up, she described a dramatic improvement in how she felt.

Symptoms That Improved

Night sweats resolved
Sleep quality improved
Libido improved
Energy increased
Irritability decreased
Menstrual regularity improved
Breakthrough bleeding improved

For the first time in months, she felt like herself again.

The only symptom that remained mildly present was occasional brain fog.

The Lab Values Told Only Part of the Story

Repeat testing was performed during treatment.

Interestingly, her estradiol level measured only 37 pg/mL.

Many patients assume symptom improvement requires dramatically elevated hormone levels.

This case illustrates why that assumption is often incorrect.

The blood draw occurred during menstruation, when estrogen levels naturally reach one of their lowest points during the menstrual cycle.

Despite that number, the patient reported substantial symptom relief.

This reinforces one of the most important principles of hormone optimization:

We Treat Patients, Not Lab Numbers

Laboratory testing is an important tool.

However, lab values must always be interpreted within the context of:

Symptoms
Menstrual cycle timing
Medical history
Clinical response

The ultimate goal is not achieving a specific laboratory value.

The goal is helping patients feel better.

An Unexpected Win: Healthier Menstrual Cycles

One of the most significant improvements involved her menstrual cycle.

Before treatment, she experienced:

Prolonged periods
Breakthrough bleeding
Irregular cycles

After treatment, she reported:

Cycles occurring every 20 to 30 days
Significantly lighter bleeding
Greater predictability
Improved quality of life

Importantly, these improvements were achieved without aggressive hormone replacement.

Instead, they resulted from restoring balance.

Why This Case Matters

Many women remain on hormonal birth control well into their late 30s and 40s while unknowingly entering perimenopause.

When symptoms develop, it can be difficult to determine whether they are caused by:

Perimenopause
Birth control side effects
Hormonal suppression
Aging
Or a combination of factors

This case demonstrates why individualized evaluation is so important.

Rather than making assumptions, we systematically identified potential contributors, allowed the body time to recover, reassessed hormone production, and then developed a treatment plan tailored specifically to the patient’s needs.

The Final Outcome

Today, this patient reports:

Better sleep
Resolution of night sweats
Improved libido
More energy
Less irritability
More predictable cycles
Significant improvement in overall quality of life

Her story serves as an important reminder that hormone optimization is not always about prescribing more hormones.

Sometimes the most effective approach is understanding what is interfering with the body’s natural hormone production, allowing recovery to occur, and providing the right level of support at the right time.
