Who We Are

The Integrative Medical Group of Irvine blends the best of conventional, naturopathic, and holistic medicine, providing comprehensive, integrative healthcare for women of all ages.

Integrative Medical Group of Irvine provide a wide range of services, including physical exams and annual women’s visits, acute and chronic care, and a full spectrum of preventive and wellness care.

Because coordinated care at one site provides the best opportunity for achieving optimal health, IMGI provides:

  • Comprehensive healthcare
  • Integrative gynecology
  • Complex disease diagnosis and management
  • Advanced testing
  • Anti-aging medicine
  • Aesthetics and skincare
  • Nutrition and fitness

Additional services include naturopathy, acupuncture, massage, and IV therapy.

We believe that…

A doctor and her patient are equal partners in health. As our patient, you should fully understand and consent to all recommended treatments.
The best treatment is the most natural, least toxic treatment. Many pharmaceuticals have terrible side effects. These powerful drugs should be last resorts, not first-line treatments.
Illnesses are usually interconnected. We want you to tell us about all of your symptoms so we can treat them together.
In many cases, the body can heal itself. Your body is designed to be healthy. If you give your body what it needs, it can usually heal all on its own.
The goal of medicine is optimal health, not tolerable illness. We want you to feel amazing.
Health is an ongoing journey. As you travel through life, we will be here for you.

Dr. Felice Gersh Interview

Dr. Gersh is the medical director of IMGI and is board-certified in Integrative Medicine and OB-GYN. She is a globally-renowned expert in women’s health and complex disease management.

Why do women live longer than men? Does the ability to bear children play a role and to what extent do evolutionary forces discriminate between men and women?

In this in-depth interview Dr. Gersh explains why she “had to unlearn” about half of everything she learned at medical school calls for a fundamental “shake-up” in the delivery of health care.

Dr Gersh discusses hormones and menopause associated weight gain ...

Concerns about weight gain are one of the leading reasons that some women are wary of using hormone replacement therapy (HRT).

Hormones play a critical role in the body`s ability to create and store energy, which translates into building, storing, and burning fat. And not just fat, but muscle, too.

Some of the questions I plan to address tonight:
* Can HRT cause weight gain and if so, what type of weight?
* Why do women in menopause tend to gain weight?
* What is weight redistribution?
* Can HRT cause weight loss?
* Can adding androgens to traditional HRT improve weight profile?

I`ll be checking here on Instagram for questions, so if you have any additional questions regarding HRT and weight that you`d like me to address, please add them to the comments of this post. And if you have any topics that you`d like me to address in future IG Lives, also let me know!

Many (but not all!) women in menopause and even perimenopause are low in DHEA and would benefit from supplementing. DHEA-S and DHEA are critical steroid hormones that play a role in virtually all aspects of health.

Watch my full talk to learn more about what this hormone is, symptoms of deficiency, testing, and supplementing. Because you can get DHEA as a supplement in any drug store or online, I also cover approaches to dosing.

I highly, highly recommend getting your levels checked and working with a knowledgeable healthcare provider to optimize your dosage, but I also know that approach isn`t feasible to everyone and I want to make sure that if you do decide to dose yourself, you do so safely.

Watch my full talk to get all the info on DHEA.
