Has anyone successfully used chiropractor to repair hiatal hernia?

No, extremely unlikely without surgery.

Sounds hokey. My husband was a chiropractor and hated those doctors who thought they could cure anything and everything. Those chiropractors gave the good chiropractors a bad reputation.

In my 20's I had a hiatal hernia, (diagnosed) The acid reflux was terrible, and the chiropractor did fix it!
I remember him taking his hand and moving them to the center of chest above that area where your ribs are at a V. I remember him using 4 fingers on both sides under that V area and pushing down towards a couple of times.
It Worked. Never had an issue again. He said it could come back but never did.

I have not been to a chiropractor in years. I mainly went for a couple of adjustments for migraines but decided I just did not want to go anymore.

I’m very skeptical that a chiropractor could ‘fix’ a hiatal hernia. Even if they could somehow manipulate the hernia back through the diaphragm, it doesn’t sound safe at all.
I frown upon chiropractors for this reason. They tend to jump right in without X-rays or much medical background sometimes doing more harm than good.

Interestingly chiropractors do like to call themselves doctors, which in reality they are not. A chiropractor is a physical therapist ranking between a nurse and a medic. I would never fully trust a chiropractor. In many cases they don't fully understand the complexity of the problem(s), their aggressive intervention could result in irreversible injuries.

As I said earlier, my holistic chiropractor was never taken to a physician. It is my belief that she could cure it.

Chiropractors do have a doctorate of chiropractic. It is imperative that you do your due diligence when it comes to choosing a chiropractor. A good one will not string a patient along and, if necessary, recommends a medical doctor.

I recently went through a whole slew of tests at a local chiropractor/ Functional medical Dr’s office .
I did tests that I didn’t even know existed along with lots of X-rays and lots of bloodwork ( the bloodwork done at a lab ).
When I went for my results, he went over everything w/ me . My gosh at 62 with all my 10 years of digestive disorders ( and after seeing 6 Gastro Dr’s having 7 diagnoses).. this guy made me feel like on was on deaths door at 62 .
His treatment plan was extensive and $9,600 .
I said , no thanks .
I went for a few adjustments and the machine that vibrates your back and neck that my insurance paid and I paid $22 co pay .
I no longer go .
I still suffer greatly but I don’t think anything he was offering would change that .

They are not Medical Doctors that can do surgery.

I agree with you. I think they do a lot of damage.
