Note to weight loss surgery patients on hydration:

It is very important in the early days and weeks following your discharge from the hospital after weight loss surgery that you focus on your fluid intake to prevent dehydration and potential readmission to the hospital.

Fluid Goal: 64 ounces (oz) each day

  • 32 oz of fluid should be from clear liquids without protein or added sugar
  • 32 oz can be from full liquids and protein supplements

Tips to help reach fluid goals:

  • Keep fluids on hand at all times. If your fluids are not with you, you cannot drink them.
  • Sip fluids slowly throughout the day. Drinking too fast or gulping can cause pain, bloating or other intolerances.
  • Sip fluids frequently throughout the day. You may only be able to drink 4-8 oz of fluid over an hour when first discharged to home. As you heal and the abdominal swelling goes down you will be able to drink more in a shorter period of time. Eventually, you should be able to drink 8 oz of fluid in 5-15 minutes. You will not meet your fluid goals if you are not drinking every hour.
  • Have a plan to drink defined amounts of fluid by certain times of the day. For example: 8 oz of fluid by 10 am, 16 oz by noon, 24 oz by 2pm, 32 oz by 4pm, 40 oz by 6pm, 48 oz by 8 pm and 64 oz by 10 pm.
  • Use a tool like Ulla to remind you to drink as time can pass quickly and it will be difficult to make up the difference later. You cannot rely on your body to tell you when to eat or drink after surgery as the physical cues will be altered.
  • Track your intake on paper logs or using a smartphone app. This will increase your awareness and make sure you meet your goals.
