Heather Yoshimura - Nurse Practitioner

You probably found me because you have already tried the things you were supposed to try.

You have been on birth control since you were a teenager. You have seen more than one specialist. You have been told, more than once, that your tests look normal. You have a heating pad at work and Advil in your bag for the days you cannot get through without it. You may have had a laparoscopy. You may have flown somewhere for an excision. The surgery may have worked for a while. It may not have. Either way, you are reading this page, which means you are still looking.

I was the patient you are now.

I had two excision surgeries in six months — the second with one of the most respected endometriosis excision surgeons in the world. I flew to the Mayo Clinic for a second opinion. I had been on birth control since I was a teenager. I followed every protocol the right doctors gave me. I had spent more than $125,000.

And I was still in pain. I had had SIBO for five years that no one had connected to my endo. My hormones were a mess. My sleep was broken. My anxiety was constant. My bloating was bad enough that some days I looked six months pregnant. And, on top of all of that, endo was impacting my marriage and eventually ended it.

By the time I was 30, my surgeons told me a hysterectomy was probably my last remaining option. I almost said yes. I am grateful I did not.

I had received the standard of care from the best providers in the country, and I still had every problem I had walked in with. So I went looking for training the gynecologists, pain specialists, gastroenterologists, and surgeons could not give me. I had to learn pain neuroscience, and why my pain had become its own disease independent of my lesions. I had to learn somatics across multiple disciplines, and the truth that chronic pain teaches you to leave your body without your permission, and that coming back is the keystone for everything else. I had to learn how the food I ate, the sleep I missed, and the way I worked were quietly feeding the inflammation. I had to learn how to regulate a nervous system that had spent decades in fight-or-flight. I had to learn how trauma lived in my pelvis. I had to learn what boundaries were, and that their absence had been a chronic dose of cortisol I did not know I was taking.

Conventional medicine did not have the language, or the time in a 12-minute visit, to teach any of that. So I learned it. And then I built it into a clinical model, because no patient should have to figure this out alone.

Today, endometriosis is a diagnosis I carry. It is not something I struggle with.

What I do

The Luteal Health practice exists because of one observation: endometriosis is not a gynecological disease. It is a systemic disease that happens to manifest in the pelvis. The pain has three mechanisms running through it (nociceptive, nociplastic, neuropathic). The systemic side has six body systems feeding into it (gut, hormones, nervous system, mind/body, lifestyle, and immune function). Most patients have all of them running at once. Almost no clinician maps them. No patient gets out of pain by treating one at a time.

That is the work. The Endo Pain Signature maps which pain types and which systems are driving your case. The Endo Recovery Protocol treats all six in coordinated care over four months. Both pages explain the structure in detail.

What I bring to your case

I am a board-certified nurse practitioner trained at UCSF, with advanced certifications in functional medicine, pain reprocessing therapy, hormone optimization through WorldLink Medical, peptide therapy through A4M, and relational training through the Somatica Institute. The full credential breakdown is in the section below.

I am also a voracious reader. There are entire bodies of clinical knowledge I do not hold a certification in, and I read them every week anyway, because my patients deserve a clinician who is current, not a clinician who is comfortable.

What I did not have, and what almost cost me my uterus and did cost me my marriage, was one provider who could see all six systems at once and treat them as the connected disease they actually are. That is the role I now play for my patients.

For the women who fall through the cracks.

Luteal Health was not built for everyone with endo. It was built for a very specific group of patients — the ones the standard model wasn't designed to help.

i.

The woman whose pain persists after technically successful surgery.

The MRI is clean. The surgeon did good work. The pain came back — or never left. That gap is where most patients get told there's nothing more to do.

ii.

The woman who wants the full picture before her next decision.

You're trying to choose between another surgery, more hormones, hysterectomy, or waiting. You want to know what's actually driving your case before you decide.

iii.

The woman optimizing her body before she goes into the OR.

Surgery is on the calendar. You want the next six weeks to be the strongest pre-op preparation possible — so recovery is shorter and outcomes are better.

I am not anti-surgery. I had two of them. I am not anti-medication. I prescribe hormones, peptides, and pharmaceuticals when they are the right tools. I am not anti-anything. I am pro-treating the whole disease, instead of the most visible 20 percent of it.

If you have tried everything for endo, you have not tried Luteal.

§ III · The Book

The Endo Dilemma.

Evidence-Based Options for Healing Beyond Birth Control and Surgery.

Conventional endometriosis treatment keeps falling short because it's built around one assumption — that lesions are the disease. The book lays out the multi-system framework that actually moves the needle: gut health, hormones, nervous system, pelvic floor, trauma, and the food you eat between appointments.

It's the plain-language version of the case I'd been making to colleagues for years — and the playbook patients can read before they ever book a visit.

What patients say.

"Working with Heather has been such a gift during a time when I felt overwhelmed and discouraged. I had surgery in 2022 for stage 4 endometriosis. It was a rough experience, and I was still in pain afterward. When I first connected with her, I had just gone through an extremely painful cycle. I felt hopeless and was seriously considering a hysterectomy at 30 because I felt like I had no other options. I also wanted to conceive, which made everything feel even heavier. Since then, I've learned how inflammation, stress, estrogen dominance, and many other factors can affect symptoms. The biggest change for me has been my cycles. My periods have been mostly pain free, which is something I never thought I would be able to say or experience. I got emotional when my cycle started and I did not even realize it. I was so used to the pain hitting me like a train days before. That alone has completely changed my life. Heather brings so much compassion and understanding to this work. She has always been incredibly supportive and genuine. I feel heard, supported, and more in tune with my body, which is something I had not felt in a long time. I am beyond grateful to have been part of what she is building and to experience something that could help many other women who feel lost, alone, or hopeless with this disease."

— J.N.

"Heather did a phenomenal job and I was really impressed with both the visit I experienced with her as well as her report. I was really taken aback by the personalization of the report and really found her to be as intelligent as she was focused. Forget being the best NP visit I have ever had, she was the best general health focused practitioner I have seen for my personal health."

— R.B.

"Heather is, hands down, the most effective and caring medical practitioner I've ever worked with. In a short amount of time, she helped me address long-standing sleep issues that no other provider has been able to solve. Heather is remarkably thorough, deeply resourceful, and tailors everything to my lifestyle and long-term health goals."

— D.D.

"I worked with Heather for over a year, and I can honestly say she made a lasting impact on my health and my trust in the care process. What stood out immediately was how deeply she listened and how open she was to exploring every layer of what was going on. She consistently took the time to research, dig deeper, and consider different possibilities."

— L.B.

"Heather really changed my health for the better with her guidance and recommendations. I'm finally sleeping through the night, down 15+ pounds, and my bloodwork is all improving across the board to normal levels. I didn't realize what I needed before seeing her — I feel the best I have in years."

— C.A.

"My goal is to be truly healthy, rather than settling for the 'not sick' standard often found in traditional medicine — Heather has helped make that possible. While there will always be health factors beyond my control, I am much closer to my ideal state of health. I truly could not have done it without Heather."

— S.Z.

"Heather is the best clinician I've ever had. I am totally impressed with her approach — very thorough and tuned in to all the things that are important for long-term health."

— J.M.

"You're a very warm, very special person. I understand why you've gone into the field you've chosen. You're well suited for your vocation."
