Gastric Bypass Side Effects

Every surgical procedure has side effects associated with the procedure. Side effects occur in the majority of patients after surgery and may require changes in eating habits or the addition of vitamins or medications.

Gastric bypass is associated with the following side effects:

  • Difficulty absorbing vitamins- especially B vitamins, calcium and iron. The part of intestine that absorbs B vitamins is bypassed so you will absorb these vitamins much more slowly. Calcium and iron absorption is affected by the drop in acidity of your intestinal tract. Taking vitamins as instructed by your doctor is critical to avoiding nutritional deficiencies after surgery.
  • Dumping syndrome- your pouch is connected to a piece of bowel that has never seen sugar. If you eat sugar after bypass surgery (not on your eating list), it will drop into this piece of small bowel. Sugar is a large molecule that draws water into the lumen of your bowel causing bowel distention. Your bowel reacts to this distention, producing nausea, vomiting and diarrhea. This reaction is called dumping syndrome and occurs in almost all bypass patients. Avoid sugar and processed foods that may contain sugar.
  • Susceptibility to developing ulcers, especially in patients that smoke.
  • Inability to tolerate NSAID medications- the pouch is more sensitive to medications in the aspirin/Motrin family. In general, bypass patients should avoid these medications.
  • Difficulty ingesting water easily- you will need to consume water more frequently but in small amounts to ingest what you need to avoid dehydration

“The staff and doctors at the New York Bariatric Group are amazing! They are always patient, helpful, and very understanding and pro-active with questions, problems, etc. After Lap Band surgery I feel fantastic. For the last 6 years I have not had to worry if my clothes would fit. I have been able to maintain my weight loss, and have so much more energy.”

"Dr. Holover has a great personality, I love him, I consider him a good friend, and I recommend him to everyone. He and his staff are amazing. I thought my recovery would be worse, but it wasn’t. It was great. After a couple of days I was back on my feet and going, with three boys you don’t have time to be down. Now, my kids have to keep up with me!"

He was genuinely concerned for me, he answered all of my questions and put me at ease. I couldn’t be happier, I think it is the best decision I ever made."

"I was concerned about my health, my blood pressure, cholesterol, my mobility, my flexibility. A few friends told me about NYBG and I went to a seminar. I wanted to live a healthier life and live a long life. My recovery was great, after a week I was 100%. My doctor, Dr. Sekhar, has the best personality in the world."

"I had a couple of friends who had bariatric surgery done by Dr. Garber a few years back and I decided to make the appointment. My favorite thing about the surgery is not being able to eat that much, eating whatever I want but in smaller portions. My results are amazing"
