After bariatric surgery you are recommended to eliminate eating from drinking. You have to drink your liquids at least for 30 minutes before a meal, and for 30 minutes after a meal. People ask, is it forever? Yes, it is forever. 

Here's why it's not recommended to eat and drink together after bariatric surgery:

  • Limited Stomach Capacity

One of the main goals of Bariatric surgery is to reduce size of the stomach and to restrict stomach capacity. Consuming both, food and liquids, together fills up the stomach quickly, potentially leading to discomfort, nausea, or vomiting and stretching the stomach.

  • Slowed Digestion and Nutrient Absorption

Drinking fluids with meals dilute gastric juices and digestive enzymes, impairing the digestion and absorption of nutrients from food.

  • Proper chewing

Need to drink with food comes more likely from too big bites and poor chewing, so you might have a wish to wash everything down with fluid. Digestion process of carbs begin in mouth by enzymes of saliva. If you do not chew your food properly, you slow down the digestion process.

  • Satiety Feeling

By consuming food and fluids separately, individuals are more likely to feel full and satisfied with smaller portions of food and longer, which can aid in weight management and prevent overeating.

  • Dumping Syndrome Risk

Dumping syndrome is quite a common side effect after bariatric surgery. It occurs when food or liquids move too quickly from the stomach into the small intestine, leading to symptoms such as nausea, sweating, weakness, and diarrhoea. Consuming food and fluids together can increase the risk of dumping syndrome. Recently doctors often mention dumping syndrome as a positive side effect of bariatric surgery as it motivates person to commit to dietary changes after bariatric surgery.

  • Hydration and Nutrient Intake

Drinking fluids between meals, rather than with meals, helps ensure adequate hydration and allows for better nutrient absorption.


By following post- bariatric operative guidelines and avoiding simultaneous consumption of food and beverages you can support your nutritional needs, optimize weight loss results, and reduce the risk of complications after weight loss surgery.
