Another happy patient:
"Dr. Ettinger not only healed my husband who was for several years with terrible case of HPylori and doctors were unable to detect why my husband was soo sick. My husband says this is the best he has ever felt in his entire life. Dr. Ettinger also healed my sister who has dealt with Lupus and chronic illness since 12 years old. She never looked soo good in her whole life. He is a miracle worker he is currently treating me for Potts and a chronic bacteria, keeping me from healing doctors have not been able to find out what's wrong with me but by the grace of God, Dr. Ettinger has found the problem.

Seriously soo grateful we met him we always send everyone we know to get treated by him. For those who don't believe in hollistic approach it's time to start. This man is a medical detective and he truly changed our lives. Thank you Dr. Ettinger."

Digestive disorders like small‑intestine bacterial overgrowth, H. pylori infection, leaky gut, or chronic gut imbalance can cause persistent discomfort and affect overall health. At The Digestion Coach we use integrative, research‑based protocols to support gut healing rather than only treating symptoms.

"Dr. Ettinger helped me with my digestion issues after three Gastroenterologists failed. His prices are reasonable and doesn't try to sell you on any of his products. The blood test he recommends is very comprehensive and I plan on having it done yearly. I highly recommend him if you have digestive issues."

Same symptoms… VERY different fixes.
IBS = your gut nerves & serotonin are out of tune
→ I fix the alarm system.
SIBO = too many bacteria/archaea living in the wrong place, making gas that jams traffic
→ I clear the traffic jam first.

The same bloating, constipation, or diarrhea can come from either one or both. That’s why a breath test can change everything. Most doctors treat the label.
I test → see the real cause → use the exact tools that actually work.
No more “I’ve tried everything.”
Just the right thing, finally.

I have run HUNDREDS of stool tests on symptomatic patients, and over the 30 years I've been ordering them, the only reported have been B. hominis and E. nana. I have had patients swear to me they have seen them, and even feel them moving inside them. They can't be convinced that they don't. Every time the tests come back negative. Genova Diagnostics not only performs PCR but also microscopic examination. Bottom line, they are rare.

Don't get scammed into believing you have parasites without a positive stool test from a reputable company. If you would like help ordering and interpreting a stool test, I have accounts with all major companies. This is because they all have strengths and weaknesses, and I can choose the test that best fits what we are looking for.
