Question:
Why do I hear that it is

Why is it not ok to drink when you eat after wls surgery? I get very thirsty when I eat and need something to drink. If I do not drink one half to one hour before and after each meal like suggested then I can not get in enough water through the course of the day. Does anyone know why you are not suppose to drink during or right before or after a meal?    — Elaine B. (posted on July 28, 2001)

There are a couple of reasons. The first one is because it HURTS!!! Another very important one is that if you are eating and drinking at the same time, your liquid will take up precious space in your small pouch and you won't be able to get enough nutrients. Also, if you drink right after eating, it will wash the food out too soon and you will lose the nutritional value. As a former drinker/eater, I can tell you that this is something that you will get used to. It was probably the hardest thing for me to adjust to along with slowing down.

The library on this site has many answers to this frequently asked question. There are many opinions and points of view given there. Try looking under post-op diet or post-op help. Do a search for "drinking" or other related words.

I think people have covered the reasons why one is not supposed to eat and drink simulaneously with an RNY procedure. However, I have to mention that this is not the case with the BPD/DS because the intact pyloric valve keeps the contents in the stomach to be processed and it isn't 'washed' into the intestines too soon. Some people experience an extreme fullness or pain upon eating/drinking immediately post-op with the DS, too. It's a pretty normal result of swelling and tenderness in the 'new stomach'. However, I did not have problems with this and drank a little with my meals. I drink whenever I'm thirsty (whether it's right after the meal or before, etc.) and have to make myself drink more water just about like everyone else on this planet! LOL The 'rule' about not eating and drinking was one of the reasons I originally investigated the DS in the first place since I was also worried about staying hydrated and being thirsty. I just couldn't see myself sticking to a schedule or worrying about when I drank in relation to when I ate (or would eat). I'm not saying this is a problem for any post-op RNY folks -- and perhaps it isn't as big of a deal further out once the pouch stretches a bit and can accomodate more. But, it was a concern for me, too. All the best, (laparoscopic BPD/DS with gallbladder removal, January 25, 2001)

If you get too thirsty when you eat, you might want to watch the sodium content of the foods you are eating. If your doctor has said not to drink when you eat, why not just listen to him? As difficult as it is (I was a take a bite/take a sip kind of person, too, once!!!) he only has your best interest (and best weight loss) in mind. Do it his way until you reach your goal. Try it your way after.

Hi Marie...it seems like you have gotten a lot of answers here but I am not sure you have gotten the one you are looking for. I had RNY and my doc told me the reason I shouldn't drink during eating and I should wait 15 minutes until after is because the liquid washes the food down so you don't fill up as fast. Since I gather from the other answers you have gotten that different surgeries have different requirements, I would suggest just point blank asking your doctor why you can't drink while eating. I am sure you won't be the first one to have asked. Good luck!

I drink up until the first bite of solid food. By the time I've cooled & chewed that first bite, most of the liquid has gone on through. I rarely sip during meals as I know it can cost me as much as 20# in the long term, so I keep the drinking til about 30 min after. I also used to down 3 HUGE glasses of milk with every meal and that's a hard habit to break. But given a choice of weighing 110 or 130? I CAN control that urge to bite 'n sip. Yes, I can do this!

I can't drink with or after meals because I vomit all of the food I have consumed and lose valuable nutrients.

Hi Marie, I had R-N-Y Feb 28th. I can sometimes eat and drink with my meal. It just depends on what I'm eating. I think to each his own. If it hurts than you are doing something wrong. Don't get me worng I don't gulp down a whole glass. I try to just take little sips if I need it while I'm eating. I think that everyone is different. I agree with the other posts that you should call and ask your doctor.Oh btw I'm down 82 pounds in 5 months. Not bad for a lightweight. c-ya and goodluck

Hi. I am only 7 days post-op VBG, but I am also a R.N. The reason my physician gave for not drinking with meals is because some foods can "swell" when they encounter liquid. So....say your pouch is 2 ounces big.......then after about 1 ounce of food, you drink several sips of liquid....if this is a food that swells when it encounters liquid, then your pouch could become full. This could present a couple of problems....one is that it could cause you to over-eat. But, suppose you ate 2 whole ounces and drank liquids immediately...if your pouch was only 2 ounces big in the first place, then you could "stretch" your pouch! We want our pouches to stay as small as possible. A little stretching is going to happen....but some of it can be prevented. My doctor said to wait at least 45 min to 1 hour after a before and after meals to consume liquids. Hope that helps.

I am 2 weeks post op. Drinking after eating makes me very very sick. I can't stand the feeling. I now have to wait 2 hours after eating before drinking. I can only eat one fourth cup at a time of solids, but can eat 2 cups of broth.
