Beyond My Menopause

Quote Icon

Patients often come to me in tears as their day to day stressors have left them imbalanced preventing them from effectively managing their daily life. They have difficulty sleeping, report low energy and libido, poor memory and concentration and emotional lability.

Medical school and residency never prepared me for this challenge even though it affects all women eventually. Unhappy with conventional therapy,
I threw myself into a more integrative approach.

Frequently Asked Questions
Dr. Mueller explains menopause and treatment options.
What is menopause?
 is defined as the end of monthly cycles signaling the end of fertility for women. The mean age is 51. Clinically, menopause is 12 months without a menstrual cycle.
What is perimenopause?

Perimenopause is the time around menopause that begins on average 

4 years
 before the final menstrual period.

What is happening to my body?

The complex balance of estrogen and progesterone in our body is shifting leading to a disruption in our normal physical and mental state leaving us to feel “unbalanced”.

Such symptoms often include:

  • Hot flashes and night sweats
  • Vaginal dryness and painful intercourse
  • Absent or irregular cycles
  • Heavier cycles
  • Skin changes
  • Poor libido
  • Depression
  • Irritability and anxiety
  • Fatigue
  • Poor memory
  • Increase in abdominal fat
  • Insomnia
  • Joint pain
How do I monitor my hormones?

Although we can get an idea of where the problem lies through careful assessment of history and symptoms, blood tests give us more information about exactly what is going on with each patient.

Blood tests:

  • Give a detailed analysis of specific hormones.
  • Ensure an accurate diagnosis.
  • Allows us to ensure the amount of hormones in your body are not higher than what is physiologically appropriate, and to know that the prescribed treatment is working effectively.
  • Help us to understand if any changes to your medication are required.
  • Are essential for monitoring your safety.
When to check my blood?

Hormones are best drawn between 8-10 AM

  • For a topical hormone cream or gel applied once daily, testing should be done approximately 10-12 hours after the last application.
  • If the topical cream or gel is used twice a day or every 12 hours, testing should be done approximately 6-8 hours after the last application.

When you first begin your journey with Beyond Menopause, we may conduct blood tests fairly regularly. But once hormone levels are stabilized, we move to more infrequent testing.

What To Expect From Our
Menopausal Service?
In the initial appointment, we need to understand whether you are perimenopausal, menopausal, or have some other hormonal condition. The first step to achieving youthful hormone balance is to have a blood test panel that evaluates a woman’s individual needs. Continual
assessment of hormone levels
 is necessary for women seeking to maintain a healthy hormonal balance.
If the follicle stimulating hormone (FSH) and luteinizing hormones (LH) are raised, this indicates 
If they are not raised, then this signifies that there could be another kind of hormonal imbalance. We also look at the baseline levels of the sex hormones: estrogen, progesterone, testosterone and DHEA. Once we establish baseline blood results, it enables us to understand the exact situation and correlate the blood results with symptoms, and this then facilitates selection of the best treatment option for you.

Understanding Lab Results

Estrogen and progesterone

For women who have monthly menstrual cycles, we check the blood hormone levels on day 21 of their cycle and analyze the estrogen-to-progesterone ratio. For longer or shorter cycles, count 8 days back from the day your next menstruation would start.

Ideally, the ratio should be 10:1. Day 21 progesterone ( in a 28 day cycle) is indicative of whether a woman is ovulating.

The pattern of hormone change varies from woman to woman, and in perimenopause, estrogen levels can spike and fluctuate.


In menopause, both estrogen and progesterone are low. When looking at testosterone, this is usually the last hormone to deplete. However, in some women, testosterone can decline before estrogen, and this can occur because there is decreased production of testosterone from the adrenal glands.

We need to measure free testosterone because this tells us how much testosterone is bioavailable (available for the body to use).

Dehydroepiandrosterone (DHEA)

DHEA is an adrenal hormone. It is a precursor to the sex hormones and gradually declines with age. Some women have a low DHEA if they have had chronic stress or trauma.
