Get my 3 simple steps to healing your gut, increasing your energy, and resolving persistent pain.

✅ No complicated food plans
✅ No expensive supplements
✅ No forever dietary changes 



What’s going on with me?

You wonder.


Constant stomach pain, unexplainable exhaustion (all the time!), bloating, brain fog, constipation, diarrhea, fear of food, food cravings, and unpredictable bathroom trips. 

These symptoms leave you confused, overwhelmed, and feeling isolated, but they all have one thing in common.

They’re related to your gut.

Your wonderful Doctor tries to help but…

Medications work in the short term, and then you’re back to square one.

Conventional approaches often focus solely on managing symptoms. While you may feel better for a while, the underlying issues may worsen over time. And then you're back to square one, frustrated and confused.

You want to feel better, to live life fully. 

But until you understand the root cause, your symptoms will continue chasing you. And no amount of nutrition, medication, diet or detoxes will help, until you look (and understand) the full picture.

Gut issues affect more than just digestion.

It’s time to say goodbye to:



Bowel irregularities



Acne, eczema, or Psoriasis


Constant fatigue

Brain fog

Focusing issues

Painful indigestion

Allergies and intolerances

Hi, my name is Dr Avraham Gundle DO. ND.

In over 30 years of private practice, I have been privileged to help hundreds of patients fully heal from crippling gut health issues. 

I specialize in integrating Functional and Mind-Body Medicine approaches that address the root cause of health problems. 

I had patients visit with a diverse range of chronic health conditions such as digestion problems, anxiety, diabetes, skin issues, weight loss, autoimmune disorders, and eczema to name a few.

These conditions had one thing in common - a gut in serious need of attention!

One of my greatest accomplishments is helping my own daughter live a healthier life. 

We are blessed with a special needs child who struggled for many years with stomach pain, low appetite, excessive weight loss, constipation, and other digestive issues. The conventional approach didn't get to the root cause of her symptoms, so I took matters into my own hands.

I created a program that helped balance her gut, ending her stomach pain, resolving her constipation, and maintaining her weight. These integrated and functional medicine approaches included a combination of diet, natural remedies,  and probiotics that were transformative to my daughter's health.

Not only that, but I personally have suffered from a sluggish and irregular bowel for most of my life and finally experienced lasting relief and wellness.

But I learnt the hard way.

I spent the last 30 years of my life literally traveling around the world to learn from experts in the fields of natural health and well-being in mind, body and spirit.

In my quest for answers, I made plenty of painful and costly mistakes until I found the right experts who I could truly learn and gain from.

I don’t want you to make the same mistakes.

What do others think?

Dear Dr. Gundle,
Please share our story with any patient struggling with inflammatory bowel disease to inspire patience and adherence to your guidance.
When my daughter L. was 11, she was hospitalized with severe stomach pain and blood in her stool, leading to an "indeterminate ulcerative colitis" diagnosis.
Traditional treatments offered only temporary relief.
Turning to you, Dr. Gundle, we embraced your belief in a cure, not just symptom management.
With your program and her levels of inflammation dropped dramatically, astonishing her gastroenterologist.
Today, she feels great and continues to thrive under your care. Your dedication and my daughter's hard work have made a remarkable difference.

Dr. Gundle Our son suffered from severe stomach pains, constant throat infections, and aching joints, which left him unable to sleep or walk well. Despite numerous consultations with top doctors, his condition only worsened. Turning to you was our last hope. Your calm and patient approach, combined with state-of-the-art diagnostics, identified the root cause of his suffering. Through a tailored healing program of cleansing diets, vitamins, minerals, and homeopathic remedies, you restored our son's health. Today, he is strong and vibrant, free from the pains that once plagued him. Dr. Gundle, you are a healer of exceptional quality, and we thank you deeply.
Mrs Novick

I suffered from reflux for 8 years and eventually even the strongest medications no longer brought relief. I consulted Dr Avraham Gundle, followed his eating plan and took the supplements he recommended. Within three months of starting his program, I was totally pain-free!

How We Work on Healing your Gut

Both women and men experience gut-related issues. It's time to heal your gut, end symptoms, and enjoy lasting well-being.

You shouldn’t have to:

  • be afraid of food because you don't know what's going to trigger you
  • feel nervous about relying on long-term medication to ease (not cure) IBS,  SIBO or other inflammatory bowel disorder symptoms
  • ‘get by’ with a chronic condition like an autoimmune disorder or arthritis
  • suffer from eczema, acne, psoriasis or other skin problems
  • experience a forever growing list of food sensitivities, allergies, and intolerances
  • deal with bouts of depression, anxiety, mood fluctuations and exhaustion 


That’s why I developed WEED, SEED, & FEED

The three core components of my program teach you how to create and maintain a healthy gut—and happier life. 


Clear the Path

In the first stage, we WEED out foods and lifestyle habits that get in the way of healing. We do this by detoxing from foods or activities that cause inflammation.


To new beginnings

I’ll share everything I know about SEEDing and cultivating a healthy gut microbiome with foods and lifestyle practices that rebalance your body.


Nourish to flourish

With a healthy foundation in place, it’s time to FEED and nurture your gut with the right nutrients and ongoing support.
