I am almost two week out from surgery (still on full liquids until Tuesday). Every time I eat (I mean drink) about 10 minutes later, my mouth turns sour. Anyone else have this problem? Not sure if it's my body (hormones) or if it's a side effect of the anesthesia. Any thoughts?

Think mine is more from the vitamin supplements and other chewables I have to take. At least that lizard breath I had, the kind that could melt lead, is gone. But, yes, my taste buds are all whacko right now, too.

This is a new one on me. A lot of people will say they have a strange taste in their mouth from the lack of carbs, but I have not heard of it being called "sour"

I wonder if you are having a little reflux, just enough to get that acid taste?

Are you taking Nexium or Prilosec?

It's a common side effect of being in ketosis. It should go away when you can eat more and your carb intake goes up.

i felt like i had a carpet factory working on my tounge over the last few days since starting full fluids. i was soooo looking fwd to this stage and everything tastes foul!! even my beloved coffee optifast turned my stomach!!!! :-( sounds like we all got issues with tastes linda.....one way or the other.

I am on a PPI - so I don't think it is reflux. Things still taste good while I am enjoying them. But once I am done the taste in my mouth turns sour. So weird. Even brushing my teeth - the toothpaste flavor turns a little bit yucky after a bit. So weird - but it does sound like everyone who has this surgery has something go wacky with their taste buds. I'm losing weight, so I can live with it for now.

I'm tell you guys, it's ketosis. Classic symptoms. :001_tongue:

Why only AFTER you eat?

Seems like you would be in ketosis ALL the time on this diet.

There are several things going on. You have a heightened taste and smell, too. So, you are really going to notice it when you eat stuff. But some people complain about having bad breath all the time as well. I didn't have it too badly, thank goodness.

I think Mac is correct on this one. I bought some Ketone strips - yeah - I'm totally in ketosis. The "sourness" seems to be a little less significant today. I know your body adapts and the initial ketosis symptoms fade away. Hopefully, that is what's happening.

I use tic tacks when I can't stand the taste any longer. They help. I try to eat a bit of fruit because I think we need fruit in our diet and I can still keep the carbs low enough and stay out of ketosis.
