Hormonal changes can affect everything from energy and sleep to your mood and focus. For many people, these symptoms develop gradually and may not be immediately linked to hormone health. But over time, they can have a real impact on your quality of life. 

 At Fontaine MD Aesthetics and Anti-Aging Medicine, Dr. James D. Fontaine uses bioidentical hormone therapy to help patients restore hormonal balance and improve long-term health. If you've been asking, "What are bioidentical hormones?" or "Is BHRT safe?" our team has the answers here. 

Call our office in San Diego, CA, to book a consultation and find out if hormone therapy is right for you. 

What are bioidentical hormones? 

Bioidentical hormones are made from plant ingredients and match the hormones your body naturally produces. These hormones act just like your own, which makes them easier for the body to use and tolerate. 

Dr. Fontaine uses bioidentical hormone therapy (BHRT) to treat symptoms linked to hormone decline, including:  

  • Hot flashes or night sweats 
  • Mood swings or irritability 
  • Fatigue and low motivation 
  • Pain during sex or vaginal dryness 
  • Poor sleep and concentration 
  • Low libido or sexual dysfunction 

At Fontaine MD Aesthetics and Anti-Aging Medicine, hormone therapy begins with lab testing and a review of your symptoms. This information helps us determine whether BHRT in San Diego, CA is a good fit and what your treatment should include. 

Is BHRT safe? 

So, is BHRT safe? When monitored closely, bioidentical hormone therapy is considered safe for most patients. Bioidentical hormones are made to work with your body, not override it. This allows for a more personalized approach and helps reduce the risk of side effects. 

Managing hot flashes and mood swings 

Hot flashes and mood swings are two of the most common signs of hormone changes. They often start gradually but can become more frequent or harder to manage over time. These symptoms also affect your sleep, which may make it harder to concentrate or stay productive during the day. 

Managing hot flashes is possible with hormone therapy. As your hormones become more balanced, mood swings and irritability often improve as well. 

Some patients notice results within the first few weeks of treatment, though full results may take a little longer. 

Addressing pain during sex 

Pain during sex is a common concern among patients with low estrogen. Vaginal tissues can become thin, dry, or less elastic, which can lead to discomfort or a change in intimacy. Fortunately, BHRT helps restore estrogen levels and support vaginal tissue health. At Fontaine MD Aesthetics and Anti-Aging Medicine, our patients find that hormone therapy improves both their comfort and confidence. 

Why hormone balance supports long-term wellness 

Hormones do more than regulate energy and mood. They also affect your brain, bones, heart, and metabolism. When hormones fall out of balance, these systems can feel the effects, even if the changes are subtle at first. By restoring balance, we aim to improve your daily function while also supporting your long-term health. 

Take the next step toward balance 

If you have questions such as, "What are bioidentical hormones?" or are dealing with symptoms like mood swings or pain during sex, hormone therapy may help. It can go a long way in managing hot flashes and more.

When I came to Dr. Fontaine several years ago, I was going into early menopause and experiencing so many symptoms. Hot flashes, fatigue, pain, brain fog, and depression that were being dismissed by my regular doctors. Dr. Fontaine was truly a godsend. He listened, took my concerns seriously, and helped me create a plan that worked for my body. Over time, we adjusted my medication, and I now feel 100% better. I’m so grateful for his care and support!

Louise initially treated me with Botox at an MD clinic I had been using for years. I was so pleased with my results, when she moved to Fontaine MD I followed her even though it was much farther away. Recently, I decided to also get fillers and expressed to her my desire for a very natural and youthful look, and she nailed it! She is a licensed RN with an Art degree therefore she really understands the anatomy and symmetry of the face. She is welcoming, professional, never rushes and very skilled at injecting both Botox and fillers, I highly recommend Louise!I also highly recommend Fontaine MD, great Doctor, and staff in a lovely, serene setting. They were instrumental in aiding me in a 20+ lb weight loss (so easy) and I could not be more grateful. I feel and look so much better and have maintained my new weight. That is not easy for many 60-year-old females.

Louise is absolutely wonderful to work with! I have seen her for both an IPL facial and Botox (my very first time!). She took the time to answer my questions, address my concerns, and put my mind at ease. I could sense that I was in the hands of someone who was going to take care of me. Louise cares about her clients and their desired outcomes. I have done IPL facials in the past with other providers and the procedures felt very harsh on my skin. With Louise, my skin was not red, bumpy, or painful after and my sunspots were treated effectively! I also trusted Louise with my first Botox experience. Louise made me feel both comfortable and excited about the natural but effective results I was hoping to have! I am thankful I found Louise and will be a returning client!

Louise listened to my skin concerns, made recommendations and completed Botox and filler procedures that that made an amazing difference!

Before seeing Dr. Fontaine, I had no idea I could feel better. I just assumed that as I got older, low energy, hormonal struggles, and general decline were just part of life—something I had to accept. Looking back, I realize how much I had normalized feeling exhausted, unmotivated, and off-balance. My energy had dipped, my sleep was inconsistent, and no matter what I did, things like weight gain and mood swings seemed unavoidable. I wasn’t in crisis—I just wasn’t thriving. Dr. Fontaine completely changed that. From the first appointment, he took the time to listen, evaluate my symptoms, and explain what was really happening in my body. Seeing my lab results was an eye-opener—I finally had real data that explained why I felt the way I did. Within a couple of months of starting treatment, I started feeling like myself again. My energy improved, my focus sharpened, and I finally started sleeping through the night. Over time, the changes were undeniable—I was stronger, my mood was steady, and I didn’t feel like I was constantly fighting against my own body. Dr. Fontaine has been with me every step of the way, adjusting my treatment as needed and making sure I feel my best. He’s thorough, knowledgeable, and truly invested in his patients' well-being. I never feel rushed in my appointments, and he always takes the time to answer my questions. I didn’t realize how much I was missing out on until I started feeling this good again. Now, I feel like I’ve regained the energy, confidence, and vitality I thought were long gone. I’m beyond grateful to Dr. Fontaine for helping me.
