Although Dr. Marina Johnson’s endocrinology practice arose from traditional mainstream medicine roots, her natural curiosity and quest for the safest, most effective estrogen hormone replacement led her to explore other therapies that she did not learn in medical school. As a top rated doctor, she believes there is a definite role for traditional prescription medicines, but many chronic milder conditions respond just as well to safer natural therapies. As a result, her philosophy is to give patients the best of both worlds. In some instances, less is more when it comes to achieving the best and safest response. In addition, Dr. Marina Johnson stresses patient education as a means to involve the patient in her own care. Working together as a team, we find the best hormone imbalance treatments to improve your health and happiness.

As one of the nation's top endocrinologists, Dr. Marina Johnson’s vast experience enables her to treat several hormone imbalance symptoms that affect a woman's overall health and long term well-being:

·Hysterectomy - A hysterectomy is an operation to remove a woman's uterus. Before having a hysterectomy, it is important to discuss other possible treatments with a top endocrinologist. A hysterectomy will stop your periods, and you will no longer be able to get pregnant. If the surgery removes both ovaries, you will enter menopause. Hysterectomy and hormones go hand-in-hand. When estradiol (your body's own estrogen) levels fall at menopause, especially if it occurs suddenly as in surgical removal of the ovaries, it's a shock to the system. Withdrawal of estradiol sets off alarms in your body causing release of cortisol and other stress hormones. Some women may only respond with severe hot flashes, drenching night sweats and insomnia. In women with a family history of anxiety disorders, estradiol withdrawal may trigger panic attacks which are the worst case of anxiety.

·Menopause - Menopause is a critical time in every women's life as it marks the end of our monthly periods and the stop of estrogen production. As a menopause endocrinologist, Dr. Johnson has personally treated over 5,000 menopausal women. She has been prescribing, measuring and monitoring "pharmaceutical" bioidentical hormones (NOT compounded products) for over 20 years. She also has expertise in andropause (male menopause), thyroid disorders, PMS and in adult growth hormone deficiency.

·Thyroid - The thyroid produces hormones that affect your body's metabolism and energy level. The three most common thyroid problems are underactive thyroid, overactive thyroid and thyroid nodules. Hypothyroidism is probably the most commonly recognized endocrine disorder. As a thyroid endocrinologist, Dr. Marina Johnson specializes in treating thyroid problems, which are often misdiagnosed and mistreated with wrong medications. Because the symptoms that occur with hypothyroidism can be similar to other endocrine deficiency diseases, it is important that an appropriate diagnosis be established.

Dr. Marina Johnson is a practitioner of functional medicine which approaches patient treatment by dealing with the cause of the disease, rather than just treating the symptoms of the disease. For example, if a nutritional or hormonal deficiency is diagnosed and treated, this may lead to resolution of a chronic illness like high blood pressure and eliminate the need for prescription drugs. Her strong background in internal medicine and pharmacology gives her the ability to evaluate your medication regimen and make proper recommendations for estrogen hormone replacement. Dr. Marina Johnson's board-certified training as a thyroid endocrinologist, plus three decades of clinical experience, provides a solid foundation for developing and prescribing sophisticated hormone protocols that are customized to each patient.

Dr. Marina Johnson is not only an expert and top rated doctor, but aggressively pursues new information and techniques to remain a top endocrinologist. She averages 80 hours of American Medical Association PRA Category 1 continuing medical education (CME) each year by attending educational programs in endocrinology, preventive and functional medicine. She well exceeds the 12.5 hours of continuing medical education (CME) hours physicians are required to attend each year. Because of her extensive knowledge and training, Dr. Marina Johnson is often asked to conduct original clinical research in seeking solutions for a variety of patients.
