Functional Medicine
Functional medicine means identifying the true root causes of your symptoms – instead of merely treating isolated symptoms. Using modern diagnostics, clear scientific evidence, and a holistic perspective, we develop a precise, highly individualized plan that helps bring your body back into balance step by step.
“Sometimes I feel like a detective when I work together with my patients to uncover the root causes of their symptoms. I really enjoy that – perhaps I would have made a good criminal investigator as well.”
Dr. Katja Aschenbrenner, M.D.
You may be familiar
with one or more of these issues:
chronic fatigue or burnout
hormonal imbalances (PMS, PCOS, perimenopause, menopause, low testosterone, endometriosis)
digestive problems, irritable bowel syndrome, leaky gut, food intolerances
joint or muscle pain
migraines, skin conditions, allergies
autoimmune diseases such as Hashimoto’s thyroiditis, rheumatoid conditions, psoriasis, or multiple sclerosis
mast cell activation syndrome (MCAS)
low mood, anxiety, cognitive changes, brain fog
These symptoms often do not arise from a single issue – but from a system that has fallen out of balance.
I am Dr.
Katja Aschenbrenner, M.D.
A physician specializing in functional medicine in Berlin Steglitz-Zehlendorf (Lichterfelde-West). I am a member of the Institute for Functional Medicine (IFM) in the United States and have completed extensive advanced training there, including:
- Applying Functional Medicine in Clinical Practice (AFMCP)
- GI Advanced Practice Module
- Hormone Advanced Practice Module
- Bioenergetics Advanced Practice Module
- Advanced training in resilience, immune system health, and pandemic management
This is how
we work with you
In functional medicine, our goal is to uncover the underlying root causes of your symptoms – truely investigative work.
exceptionally thorough initial medical history
comprehensive laboratory testing (blood, gut, hormones, micronutrients)
targeted nutrition and lifestyle interventions
optimization of minerals, trace elements, and hormones
support of metabolism, mitochondrial function, and digestion
integration of evidence-based naturopathic approaches
This approach to medicine is science based modern, and future-oriented.
“Functional medicine restores healthy function by treating the root causes of disease. The functional medicine framework allows clinicians to systematically identify and address the underlying processes and dysfunctions that are causing imbalance and disease in each individual.”

Story
I discovered functional medicine while searching for answers that were missing in conventional medicine. What fascinated me was how precisely functional medicine identifies connections – between hormones, gut health, the immune system, mental well-being, and metabolism. Today, I am inspired every day by helping people with this approach – especially those who have been searching for answers for years.
What Treatment in Functional Medicine Looks Like
Step by Step
Comprehensive initial consultation
We thoroughly discuss your symptoms and their progression, medical history, environmental influences, nutrition, stress, and sleep.
Targeted diagnostics
Modern laboratory tests (blood, stool, hormones, micronutrients) reveal where imbalances exist.
Individualized treatment plan
Nutrition, lifestyle measures, micronutrients, and – if appropriate – bioidentical hormones and medications are tailored specifically to you.
Ongoing support & adjustment
We work closely together, monitor progress, and adapt the plan to your individual development.
Addressing Common Concerns & Beliefs
“Do I have to completely change my life?” No. Small, well-chosen changes often have a significant impact – the key is that they fit realistically into your daily life. “How is this different from conventional medicine?” We use conventional medical knowledge, but take a deeper, more individualized approach. It is not an either-or situation, but a complementary and integrative one.
Who Is Functional Medicine
Suitable For?
Functional medicine is particularly beneficial for people with:
- chronic symptoms without a clear diagnosis
- autoimmune diseases
- hormonal imbalances
- digestive disorders
- cognitive changes or a family history of dementia
- fatigue, sleep disturbances, or stress-related conditions
- complex, multifactorial symptoms
- menopause or perimenopause
And for anyone who wants to strengthen and improve their health sustainably.
Functional medicine is not particularly suitable for you:
- if you are looking for a quick “reset” without deeper work
- if you do not want comprehensive diagnostics or laboratory testing
- if you are seeking exclusively “alternative” or non-evidence-based treatments
- if the goal is solely rapid symptom suppression
Do I really need to have blood tests done?
Laboratory values are often essential to identify imbalances that are not visible at first glance. Blood tests are performed at our partner laboratories, where the staff is highly experienced. Many patients find the process much easier than expected – and benefit greatly from the clarity the results provide.
How long does it take to notice improvements?
This varies individually. Some patients notice changes within days or weeks, while more complex conditions require more time. The goal is not quick symptom relief, but long-term stabilization of your overall health.
Can functional medicine be used alongside conventional medical treatments?
Yes. It often complements conventional medicine very effectively and improves stability, energy, and quality of life. Proper coordination is important and will be discussed together.
