Bio-Identical Hormone Replacement Therapy

Bioidentical hormone replacement therapy (BHRT) is a comprehensive, non-surgical procedure that helps the body regulate itself naturally. Hormones represent the control panel of the human body. As we age, our hormone levels decline or fluctuate. The best way to restore energy, a keen mind, and a strong, fit body is by balancing hormones. BHRT can help return the body to its optimal physiological state.

Hormones such as estrogen, testosterone, triiodothyronine (T3) and thyroxine (T4) are all extremely important factors in maintaining cardiac, musculoskeletal and cerebral health.

About Hormone Treatment

Many people wonder why they experience fatigue and weight gain, despite eating healthy foods and engaging in a vigorous exercise program. The key to maintaining a stable physiologic state is balancing hormones to maximize the benefits of proper diet, exercise, and supplements.

We customize our bioidentical hormone replacement therapy for each individual. Both men and women can benefit from BHRT because it balances hormone deficiencies by harnessing the exact biochemical structure of the human hormone.

BHRT is an ideal treatment for menopause, andropause and other age-related conditions. Estrogen and Testosterone replacement therapy and a few of several treatment options to balance hormones. Derived from natural plant-based ingredients, our bioidentical hormones are not animal-derived replicas. BHRT are proven to carry fewer risks than synthetic options, which are sometimes associated with breast cancer and/or cardiovascular disease.[1]

How Is BHRT Administered?

Hormone treatments can be delivered via pills, creams, gels, oils and shots but those methods all have a peak-and-valley effect. The human body secretes hormones in a more regulated, steady manner. Hence, the most effective way to receive BHRT is through pellet therapy.[2] Since pellets are administered under the skin and directly into the bloodstream, the body continuously extracts the correct amount of hormone on an ongoing basis that lasts several months.

Benefits of BHRT

The aging process affects us all differently. Some people grow wearier as time passes while others experienced diminished sex drive, weight management challenges and difficulties with their sleeping patterns. The best way to determine how BHRT can address your individual needs is to schedule a consultation with Dr. Castillo and explain which specific benefits you seek. 

Hormone Replacement for Women

Hormone Pellet Therapy in Women

Although it may sound counterintuitive, testosterone therapy has proven to be extremely beneficial for many women as they mature.[3] BHRT offers the body a natural testosterone boost, which can be highly preventative against breast cancer, osteoporosis, Alzheimer’s, and other forms of dementia, just to name a few.

Menopausal women often struggle with insomnia. One of the major benefits of BHRT is its ability to help regulate sleep patterns and thereby replenish one’s energy.[4] Hormone therapy for women can also restore the loss of lean muscle tone, increase libido, and stabilize mood swings to address anxiety and depression related to hormone imbalances. Additionally, women can remedy their loss of bone density and prevent osteoporosis with the help of BHRT.[5]

Hormone Replacement for Men

Hormone Pellet Therapy in Men

Many of the benefits enjoyed by female recipients of BHRT can also translate to their male counterparts. Men who wish to experience a boost in mental focus, decrease in fatigue or loss of libido should call (925) 905-9922 to learn how hormone replacement therapy can improve their general health.

One of the perks of BHRT that is specific to men’s physiology is its ability to address loss of libido. Adequate testosterone levels are crucial to drive, focus, lean muscle and are important to maintaining libido. Erectile dysfunction is another common concern among men that may benefit from adequate testosterone. It would be an oversimplification to state that testosterone therapy alone immediately restores a man’s erectile function, but it can safely and effectively treat one of the underlying causes of ED. For example, testosterone replacement has been proven to address some of the complications associated with diabetes.[6] Inconsistencies in blood sugar levels tend to lead to a depletion in nitric oxide, the compound responsible for providing rigidity to the penis during arousal.[7] Hormone replacement therapy can replenish testosterone levels, in turn alleviating nitric oxide depletion due to diabetes. By treating a man’s wellness holistically, Dr. Castillo can remove some of the obstacles to his sexual issues and improve his overall quality of life
