Water is life. According to the CDC, water has so many functions in the body including temperature regulation, lubrication and cushioning of joints, protection of sensitive body tissues, and ridding our body of waste through bodily fluids such as urine and sweat. These functions do not change after bariatric surgery. In fact, individuals who have had bariatric surgery should be even more vigilant about getting in enough fluids. Because eating patterns and portion sizes are different after bariatric surgery, it can be an adjustment to get in enough water, which puts individuals who have had bariatric surgery at a higher risk for dehydration.

How Much Should I Drink After Weight Loss Surgery?

The fluid goal after surgery is 60-80 oz per day. Fluids that count towards this goal include water, non-carbonated beverages, decaffeinated beverages, sugar free beverages, and non-alcoholic beverages. So, get in that fluid! Below are some recommendations for ways to spice up your fluid intake:

  • Plain water
  • Flavored water
  • Protein shakes
  • Broth
  • Decaffeinated coffee
  • Decaffeinated tea
  • 1%, skim, or plant-based milk
  • Sugar-free popsicles
  • Sugar free Jello
  • Sugar free juice
  • Protein waters
  • Sugar free sports drinks
