Living Longer and Better with Hormones: Bioidentical Hormone Replacement Therapy

At approximately age thirty-five, perimenopause (for women) and peri andropause (for men) begins and people experience a decrease in hormone production. Stress can also catalyze hormone deficiencies. 

No matter the cause, the symptoms of decreasing hormone levels are the same and may include a loss of libido and energy, a diminished sense of well-being, less ability to control body composition (i.e., difficulty getting rid of a stubborn layer of fat around the middle), decreased cognitive function, anxiety, and insomnia—just to name a few. 

This is when bioidentical hormone replacement therapy (BHRT) is very useful. We’ve learned how to restore hormones to youthful levels and restore patients’ vigor and vitality with few side effects (which we’ve also learned how to manage). 

Cheating Hormonal Decline in Both Men and Women 

On the surface, the logic of BHRT is simple: we lose hormones as we age, but now we can restore these hormone levels to where they were when we were younger. It’s not just about numerical hormone levels, though. As I’m fond of saying, we treat the patient, not the numbers.

Why Do We Experience Hormone Deficiencies?

While aging is the primary reason we experience hormone deficiencies, stress can accelerate the decline. Most people start losing hormones at age thirty-five, but people under significant stress can start losing them even earlier. Given the society in which we live and the pressure many of us are under, it’s not surprising that people today lose hormones faster than hundreds of years ago in an agrarian society.

We fail to get adequate sleep, don’t eat or hydrate properly, and fail to do stretches or use other techniques to help our soft tissues loosen after intense exercise. All of these factors can contribute to hormone loss. 

The term sick thyroid refers to how the thyroid gland reduces its hormone production because of overwork. Many years ago in human societies, the thyroids of people who couldn’t hunt and gather because of injury or illness reduced hormone production in order to save energy. Today, if we overtax our bodies, the thyroid responds similarly. 

Detection

Doctors rely on two methods to determine if hormone deficiency is occurring. First (and foremost), we look for the signs and symptoms just described, factoring in the age of the patients and how much stress they’re under. Second, we take blood samples to measure hormone levels that support why an individual might be experiencing their symptoms. 

Though hormone replacement isn’t the only option when we determine a deficiency exists, it’s often the best one.
