Eating After Weight Loss Surgery

There is a whole section about nausea and vomiting, but essentially it boils down to this: if you vomit, stop eating and drinking for a while—give your stomach a rest.  Then resume a clear liquid diet.

Don’t give up on any foods.  There are foods which do better immediately after surgery, but one day tuna fish may not do well, and the next day tuna fish may do just great.

Nausea

Nausea is common the first few weeks after surgery. Your stomach was sutured, it is painful, it wants to rebel, and it will.  Most nausea comes from overfilling your stomach with too much food or fluid.  Once the stomach distends it feels uncomfortable and you will feel nauseated.  When the stomach becomes more filled it will produce more acid. The more acid in your stomach, the less your stomach likes it.  Overfilling the stomach, and too much acid, both cause severe nausea.  When you are nauseated you may also find certain odors bother you (cigarettes, cheap perfume, my mother-in-law’s cooking).
 

• Remember the size of your stomach and do not over fill it. (Simpson commandment number one).
• Take the Pepcid® or Zantac® daily (or Nexium®, Prevacid®, etc.) Pepcid Complete is a great product that allows you to have immediate relief from stomach acid as well as having Pepcid to keep acid decreased later.
• Keep something in your stomach. Some of our patients have found that Matzos works well (it can be found in the international food section of most supermarkets).  Matzos have little salt, and are rather bland.  But every pregnant woman will tell you that a soda cracker soaks up acid and can help with nausea.  Remember, this is early in the postoperative period, the first twelve weeks—we do not expect that crackers, which have high carbohydrates, will be a part of your daily food.
• Odors can cause nausea. Your husband or wife will have to smoke outside. My patients refer to this as the bionic nose.
• Some herbal teas help with nausea, such as Lemon Lift, Peppermint, or Ginger. But if you overfill your stomach or pouch, you will defeat the purpose.
• Avoid all carbonated beverages.  Some surgeons believe that carbonation can stretch the stomach, and even disrupt staples in the early postoperative period.  There is little evidence to prove this, but unless your surgeon says it is okay, don’t do it.  While carbonation seems to work well in some stomachs, you have to remember, your stomach now contains a lot less space.
• The narcotics in pain medicine can cause nausea.  Codeine, Percocet® are two of the more common ones.  Sometimes patients have to simply avoid narcotics and use Tylenol® for pain.
• Keep drinking fluids. Your goal is 2 quarts a day (about 2 liters is fine).  Sip.  But remember, you do not have to drink all of this at once.  Keeping a sports bottle filled with water is a good thing to do.

Vomiting

Vomiting is awful. Often it happens because you overeat.  You have a limited amount of room, and if your stomach does not empty fast enough, you will distend the stomach and you will vomit.  So you must learn portion control. If your stomach holds four ounces, that is eight tablespoons, if you have one teaspoon too much you can feel awful, vomit, you may stay nauseated all day long, and you may not be able to hold food down.

Remember do not eat and drink at the same time early on.  When you had a 50-oz stomach this was okay, but fluids fill your DS 4-oz stomach very fast and a RNY or Lap band one-ounce stomach even faster (one medicine cup or shot glass is one ounce).  If you eat a couple of ounces and then drink some water you can quickly over fill your stomach.  These rules can change after a while; we are talking the first few weeks here.

Vomiting can become a cycle. If you keep vomiting, the outlet from your stomach can swell, obstructing your stomach and causing more vomiting.  This can either be the stoma, in the case of the RNY or lap-band, or the pylorus, or any portion of the stomach.  Sometimes we have to put patients in the hospital and give them intravenous fluids because of intractable vomiting.  Often if we limit the amount they can take by mouth and go back to clear liquids we can stop the vomiting.  If you are having trouble with nausea and vomiting do this:

You may be given a prescription for Reglan® to help empty your stomach.  Some patients find that liquid Reglan works better than pills.  Reglan works particularly well for patients who have diabetes, as they might have a "diabetic gastropathy" which essentially means your stomach doesn’t empty well.  This condition usually improves with time.

Once you are feeling better you may advance your diet gently.  Remember, when you vomit, we go back to the beginning, just like in the hospital.  Stop eating, wait a while, begin a few clear liquids and go from there.

Sometimes patients vomit because they try something that does not agree with them.  Usually this is meat.  The stomach, at first, may have a difficult time digesting certain meats and vegetables.  This is why we advocate that you add one thing new to your diet per day.  If something does not agree with you today, try it later.  Red meat takes some patients three months before they can tolerate it—except for Tammy.  Tammy on her fourth postoperative day was given beef tips.  Sure enough, she ate them.  She did very well in her postoperative period, and was able to get to her goal in a year.

If all this fails, call your surgeon.  If you can only keep water down we need to know.  This is usually an exaggeration, and your surgeon will want to hear what you can keep down, and what you cannot.  If you can only keep water down, then it is fine to drink water for a couple of days.  You will not melt away.  If you truly cannot keep anything down your surgeon will want you in the hospital.

Remember; just because you have this surgery does not make you immune from the flu, stomach viruses, food poisoning, bowel obstruction, or a host of other problems. Do not hesitate to talk to your family physician regarding your vomiting, especially if the flu is going around. If you are having vomiting and diarrhea, you may need intravenous fluids sooner rather than later.

Warning—preventable brain damage

Repeated vomiting episodes can quickly lead to a vitamin deficiency that can cause brain damage, a peripheral neuropathy, and muscle wasting. This can be prevented with vitamin repletion. While hospitalized, it is important to have IV fluids with the yellow stuff (multivitamins) in it, especially if you have been admitted more than two times for dehydration. If you are in another city or are being admitted by different doctors for dehydration, be sure to ask that they include multi-vitamins with their intravenous hydration.
