Possible Nutritional Complications After Weight Loss Surgery
Weight-loss surgery is effective in providing significant weight loss as well as improvements in comorbidities, like diabetes and sleep apnea. Many of the potential complications are caused by a deficiency in the proper nutrient intake or the lack of following the guided behavior changes that are recommended before choosing to have bariatric surgery.
Below are a few guidelines to assist you in avoiding nutritional complications after the operation.
Nausea and Vomiting
Nausea, vomiting or abdominal discomfort are usually due to one of the following:
- Taking bites that are too big (larger than the size of an eraser)
- Eating too fast
- Not chewing your food to applesauce consistency before swallowing
- Eating foods that are dry or harsh
- Drinking with your meals or too soon after you have eaten
- Eating too much at one meal (Remember, your new pouch is about the size of a small egg.)
- Lying down too soon after eating
Frothing is a white mucous liquid that your pouch might produce when dehydrated or overstimulated. This is your body’s way of protecting itself, which may cause you to be nauseated as well.
This may occur when your body is preparing to vomit or attempting to release any food that is stuck in the pouch. If this is happening, your pouch is seeking to lubricate itself. Your nose may feel full after you eat, which is part of the frothing process. If this occurs, slowly sip a mildly acidic liquid, like tea with lemon.
The key to preventing this is to:
- Stay hydrated by consuming a minimum of 48 ounces of fluids.
- Take tiny bites (pea size).
- Chew your food thoroughly before swallowing.

This is specific to gastric bypass surgery. Dumping occurs when the undigested food in your stomach is transported or “dumped” into your small intestines too quickly. Symptoms include feeling nauseous, vomiting, bloating, cramping, diarrhea, dizziness, feeling tired or weak, and sweating. You may feel like you have flu-like symptoms.
This can be avoided by avoiding high-sugar or high-fat foods. If you have had gastric bypass surgery, you need to follow a meal plan that omits simple sugars. You should not have more than 15 grams of total carbohydrates in one sitting.
