Drinking soon after eating

If it's not uncomfortable, is there any good reason not to drink right after eating for VSG folks?

Edit:

To clarify, I do not drink soon after eating - I am just interested in researching whether there is any real basis to applying that rule to VSG.

Wow - this study! It's very small but fairly recent. It found that smooth soup delayed gastric emptying and increased satiety more than chunky soup or solid food! https://www.ncbi.nlm.nih.gov/m/pubmed/23093339/

This old study found that drinking while eating does not increase gastric emptying:

Things I've learned reading studies to try to answer this question this morning:

  1. A hot meal seems to move through the stomach faster than a cold meal.
  2. lying on your left side keeps food in your stomach longer while standing makes food exit the stomach faster.
  3. Soup moves through the stomach slower than the same ingredients not blended into a soup but eaten at the same time as drinking water.

Keeping food in your stomach longer is exactly what satiates hunger. Drink and wash the food out, and you will constantly be hungry.

VSGers still have their pyloric valve. Eating dense food closes the valve, and a full stomach means you are happy, and eat less.

Drink liquid and the pyloric valve opens, emptying the contents into the digestive tract. You are able to eat more, and will. You stay hungry. You could eat all day.

Drinking with meals for any surgery pretty much negates its usefullness.

I think I'm not convinced that the pyloric valve would open on a stomach with dense protein in it because some liquid is introduced. Are you sure it would?

It would. It's the way the pyloric valve is supposed to work.

I'm searching for a newer study, but so far I've found this: https://www.ncbi.nlm.nih.gov/m/pubmed/7083695/

adding liquid to dense food in the sleeve allows the food to turn onto" soup" more quickly and any liquids leave the sleeve sooner.

Yeah, bad idea. I think VSGers can get away with a sip to wash down a dry bite easier than RNYer's but still need to avoid it. I just stopped bringing/ordering drinks with meals.

Plus, it hurts like hell. I have done it by accident before (eat dinner, walk away from the table and take a big ol' swig of a water bottle without thinking). OUCH.

The way it was explained to me is dense protein take a long time to be digested/broken down and that's why you feel full longer. Because they stay in the stomach longer therefore you feel full. Liquids just wash them through the stomach faster which means you'll be hungry faster.

The example I remember best is thing about if you put applesauce in a sieve and how long it would take to move through the sieve on it's own (representing food digesting in the stomach) and then think about what happens if you add water to the applesauce - it goes through much faster. Same with your stomach.

30 mins is not a long time to wait to drink and its a good habit to break: drinking while eating.

None of those studies are with people who have had WLS. Our anatomy is completely different.

I'm sorry, but it looks like you are searching desperately for some rationale that allows you to drink with meals. You don't need permission.

If you decide to drink with meals, please post your weekly weight loss results over the next 5 years. I'll be happy to use your results as a case study.

I don't plan to start drinking with meals, I just like to discuss the science or lack of it behind the rules we follow. I think VSG does not change anatomy so drastically that studies done on normal stomachs wouldn't have some weight.
