System-based Care for Complex & Chronic Conditions
Root‑Cause Integrative & Regenerative Medicine
Neuroregeneration Chronic Pain Conditions Autonomic Dysfunction Post‑Surgical Recovery Fracture and Tear Conditions Personalized, Mechanism‑Focused Treatment Plans for Complex and Chronic Conditions.
Chronic and complex conditions rarely come from a single cause. Many mechanisms cannot be seen on imaging or blood work, and true progress often comes from identifying the right direction rather than searching for one perfect answer. Integrative Medicine focuses on understanding systems, recognizing patterns, and guiding the body toward repair — even when the root cause is multifactorial or not fully visible.
Why Diagnosis and Evaluation Comes First?
Many symptoms—such as pain, fatigue, dizziness, numbness, and brain fog—can arise from multiple interacting systems. Effective treatment begins with understanding the underlying mechanisms contributing to each individual's condition. 1. Comprehensive Assessment Every patient receives a thorough evaluation that may include medical history, physical examination, neurological and structural assessment, and review of previous imaging or laboratory testing when appropriate. 2. Root-Cause Identification Chronic symptoms are often influenced by multiple factors, including neurological, structural, metabolic, inflammatory, autonomic, and lifestyle-related systems. Our goal is to identify the mechanisms most relevant to your condition. 3. Personalized Treatment Strategy Therapies such as FSM, PEMF, regenerative-oriented injections, nutritional support, structural correction, acupuncture, and lifestyle interventions are selected only when they align with the underlying mechanisms identified during evaluation. 4. Monitor, Refine & Optimize Recovery is an ongoing process. Treatment plans are continually monitored and adjusted to support healing, restore function, and achieve long-term improvement rather than temporary symptom relief.

Regenerative Medicine
Regenerative medicine focuses on restoring function by supporting the body’s natural repair processes.
Rather than suppressing symptoms, regenerative approaches aim to improve tissue healing, nerve recovery,
and long‑term resilience.
This includes mechanism‑based therapies such as FSM, PEMF, regenerative‑oriented injections, metabolic
support, and structural correction — selected only when they align with the underlying mechanisms
identified during evaluation.

Dr Chang has been a godsend to me. I came to see Dr Chang because of high potassium in my blood. My Nephrologist told me that my kidney is functioning normally but he do not know the reason for my Hyperkalemia. In just one consultation and a blood test, Dr Chang was able to found out the root cause. Now I do not have to take the thousand dollars a month medication (Lokelma). I highly recommend her!

Dr. Lily Jei-ho Chang is an absolute godsend! I sought her out after experiencing severe complications following recent ER visits and antibiotics that wreaked havoc on my body and caused frightening, unexplained symptoms, in addition to some ongoing chronic issues. After feeling dismissed, unsupported, and without answers or recourse from my primary care team (other than more prescription medications, or a multi-month waitlist to see specialists), I wanted to believe there was another way. And indeed, there is! After my first comprehensive consultation with Dr. Chang, I finally felt heard and knew I was in excellent, capable hands. She takes a truly holistic approach, looking at the interconnectedness of the body rather than treating symptoms in isolation. My first Frequency Specific Microcurrent (FSM) treatment was incredibly transformative. I experienced immediate relief, particularly in calming my nervous system, which has been in overdrive, and inflammed, angry joints. I also noticed improvements in my breathing, GI symptoms, better and an overall sense that my body was finally beginning to heal. After my allergy panel review, second FSM treatment and first allergy treatment this week, I am feeling much more empowered and like I’m actually reclaiming my health. I am experiencing a level of clarity and calm that I haven’t felt in what seems like forever. Some of the frightening neurological symptoms I had been experiencing—including persistent migraines, tingling, shaky hands and tremors, and sensitivity to light, noise, motion, as well as joint pain —have noticeably subsided. Additionally, I notice a huge improvement in overall mood and increasing energy again. It is absolutely amazing to experience this kind of relief after everything I’ve been through. Dr. Chang identified environmental allergy triggers and is taking a much less invasive, individualized approach to helping me address them. Rather than simply relying on temporary symptom relief, she is working with me to understand and address the underlying factors contributing to my symptoms. It’s remarkable to finally have a practitioner who takes the time to investigate, explain, and treat the bigger picture. If you find yourself without answers or frustrated with the limitations of conventional medical care, as I did, do yourself a favor and connect with Dr. Chang. Her approach is truly exceptional, revolutionary and my experience with her has been one of the most transformative and life-changing experiences I’ve had. I am incredibly grateful to her and look forward to continuing my healing journey. This is what medicine should feel like: compassionate, comprehensive, and focused on helping you truly get better. Dr. Chang has got you covered in spades. I am so very grateful to have found her and I know you will be too.

Dr. Chang is the very best! Her approach is to devote time to fully understand your medical situation. Armed with this understanding, she diligently works to address the real cause and not simply the symptom, which is refreshing. She is well versed in all types of medicine and uses her vast knowledge to truly help her patients to a speedy recovery. Wish I could give Dr. Chang a 10 STAR rating!!

My experience with Dr. Chang has been both healing and revealing! I have had hot flashes for 18 years and have tried all types of herbs and diet restrictions…all to no avail. Because of Dr. Chang’s saavy questions, innovative equipment and specific targeting to address the source of my hot flashes, I am sensing fewer and less severe symptoms after just 2 treatments. This is a new lease on life and I highly recommend the experience.

I came to Dr Lilly Chang due to extreme pain in left shoulder. Later found out by an MRI that I had a severely torn rotator cuff, dislocated bicep muscle that needed to be cut and relocated in bone by pin. I also had scar tissue in joint and 2 bone spurs cleaned out. A week before my surgery, I saw Dr. chang. and was on FSM. It immediately dulled pain. I used it 20 hrs a day. 10 hrs longer than prescribed. It was uncomfortable the first 2 days. But then I could tell when the machine went off. The pain would begin to radiate and I couldn’t wait to start over. After surgery I was not able to get it on till day 2 because of the bandage locations. Once I did it was immediate pain relief and never removed it till my first Physical Therapy apt. The therapist did an initial overview of my pain and then stared testing my range of motion. He was completely amazed!! He had never seen my range of motion after such an extensive surgery 1 week out before. He was very impressed and interested in the multi current machine. I see my orthopedic surgeon tomorrow and can’t wait to share the results with him as well. I decided to lower my pain meds dramatically and it absolutely possible with my FSM machine. My husband and I are purchasing a machine and will use it in the years to come! Thank you Dr Chang 🩷
