Would like to know.
If the acid production is shut down, it increases the secretion of gastrin by negative feedback mechanism. Long term use may result in gastric polyp formation which have been found to be harmless. In rats it has been found cause a tumor called carcinoid. But there are no reports of PPI causing carcinoids in humans.
The acid environment of stomach forms a protective barrier against infection. When it is altered due to acid suppression by long term PPI, bacteria and other organisms can gain entry in to the gut causing diarrhea which can be controlled by stopping PPI or by adding probiotics.
There is a recent controversy that PPI affects calcium absorption resulting in worsening of osteoporosis in very elderly patients.
All the above mentioned effects are not common associations.
PPI are less than 2 decades old . More time is required to know the effects of life long use of PPI.
Thats why I told in the previous message that it is better to use PPI when you have symptoms (on demand) rather than continous therapy.

However, I do see the position both the drug companies and our doctors are in. There is just not enough long term evidence in and so they have to be cautious. I did see in one response that many of these drugs (like prilosec at 20 mg) only supresses about 80% of acid production. Perhaps there in lies the key. Not ALL acid is suppressed and therefore enough remains for homeostasis of stomach function in terms of bacteria, Ca absorption etc. etc.
I think we as patients need to experiment with this. I take prilo daily, then on occasion stop and see how it goes (especially if I'm careful with my diet). If I have several days of heartburn, I'll go back on the daily preventive. We certainly do not want to cause problems trying to prevent them, but both sides of the equation have issues - too much acid = heartburn, Barretts esophagus, and other changes in the esophagus OR too little acid and bacterial growth, Ca issues and polyps etc. etc.
I'm sure in the upcoming years we'll know more. Thanks Kini for the more detailed answer.
Here's an interesting excerpt:
Prilosec and Nexium
Heartburn can be uncomfortable, but heart attacks can be fatal, which is why the FDA has investigated a suspected link between cardiac trouble and the acid-reflux remedies Prilosec and Nexium. In December 2007, the agency concluded that there was no "likely" connection. Translation: The scientific jury is still out. In the meantime, there are other reasons to be concerned. Because Prilosec and Nexium are proton-pump inhibitors, they are both incredibly effective at stopping acid production in the stomach — perhaps too effective.
A lack of acid may raise your risk of pneumonia, because the same stuff that makes your chest feel as if it's burning also kills incoming bacteria and viruses. You may also have an elevated risk of bone loss — in the less acidic environment, certain forms of calcium may not be absorbed effectively during digestion. "The risk of a fracture has been estimated to be over 40 percent higher in patients who use these drugs long-term, and the risk clearly increases with duration of therapy," says Dr. Rodgers.
