What is the difference between hiatal hernia, gerd, and achalasia?

HH, GERD, achalasia. Simplistically, a sliding hiatal hernia is a common upward bulge of stomach (with acid) thru the diaphragmatic hiatus (hole in diaphragm thru which esophagus & stomach connect). Gerd is physical movement of stomach contents into the esophagus, often associated with esophageal inflammation that can progress to esophageal cancer. Achalasia is motility disorder of esophagus and its lower sphincter.
Big difference. Hiatal hernia is an anatomical problem, gerd is a functional problem with the valve between the stomach and esophagus being "too loose", and achalasia is a problem whereby the esophagus doesn't function at all due to loss of nerve function. The normal valve between the esophagus and stomach then becomes stiff, making swallowing food progressively more difficult.
? Hiatal hernia is a hernia at the esophageal hiatus through the diaphragm. Gerd is acid reflux from the stomach into the esophagus. Achalasia is hypertrophy/ stricture at the distal esophagus. Gerd can be associated with both hiatal hernia and achalasia but more so with hiatal hernia.
Se. Below. Herd is a symptom of hiatal hernia achalasia a a nesophogeal motility disorder when part of your stomach is in your chest the sphincter of the end of the esophagus dosent work as well to close off the esophagus-.
Big difference. Hiatal hernia is when the stomach goes up in to the chest because the hole in the diaphragm for the the esophagus stretches out. Gerd is abnormal reflux of stomach contents into the esophagus typically causing heartburn and regurgitation. Achalasia is when the esophagus doesn't work to propel food through the esophagus and in to the stomach.

Can I continue my passion of weightlifting despite having a GERD and hiatal hernia.

Absolutely. Symptoms of gerd can be aggravated by heavy straining, and if this the case, surgical consultation should be considered, as anti-reflux surgery can be very effective if diminishing these symptoms. Behavior and diet modification is imperative as well. See your physician.

Are you more prone to having esophagus polyps after having one with severe GERD and common hiatal hernia?

Not true polyp. Esophageal polyps are called pseudopolyp, mean not real polyp, caused by the inflammation driven by the reflux, there are not a true polyp that can turn to cancer and they diseapear with treatment so try to take care of your reflux, follow the diet, no late meal, or snack, sleep with head elevated, take medication as Rx, avoid caffeine and spicy food, and eat multiple small meal, avoid tight cloth.

I have been diagnosed with GERD hiatal hernia (maybe also asthma) 3 months ago, I am also v stressed. Could it be all from stress or worse from it?

Relux workup. Although stress plays an important role in our health, gastroesophageal reflux (gerd) disease is caused from numerous factors. Some to consider: alcohol and tobacco use, diet, anatomy (hiatal hernia), obesity, and medications. Work up with endocsopy, ph (acid test) probe, xrays (upper gi), and possible manometry (pressure tests) are necessary. Treatment begins with medication and lifestyle change.

Have GERD hiatal hernia had dialation xs 3 in 6month been on several meds only help awhile also have schatzki ring would I benefit the fundoloplicatio?

Yes. Reflux might be the source of the ring. In that case an anti reflux operation would help but I advise a motility study of the esophagus prior to considering surgery. If motility is impaired your condition will worsen with surgery.
Maybe. Need a more complete picture of symptoms, size of hiatal hernia, and general medical condition. The ring has nothing to do with hernia or GERD. After anatomic & physiologic testing, you may be a candidate for an endoscopic procedure such as Stretta, or a surgical fundoplication. Gastric bypass is even an option in obese patients also considering weight loss surgery. Hope this helps!

Please talk to me about melatonin vs ppi's for gerd...I have a moderately sized hiatal hernia.

Go with ppi. I know of no role for melatonin as treatment for reflux made worse by hiatal hernia. Melatonin is a sleep aid. Ppis are proton pump inhibitors and reduce acid production in stomach at the source - helping to relieve reflux issues common with hiatal hernia.
