Drinking and Nutrition in the First Week After Bariatric Surgery
The stomach is very sensitive at this stage, so nutrition is limited to fluids and staying hydrated is the top priority. Find the full details in our guide to drinking water after bariatric surgery.
Small sips
Drink slowly and frequently throughout the day, never large amounts at once.
Liquid protein
Approved protein supplements protect your muscles and speed up wound healing.
Avoid
Fizzy drinks, sugars, too much caffeine, and drinking through a straw.
Pain and Wound Care
- Incision pain: mild and controlled with painkillers prescribed by your doctor only, avoiding drugs that harm the stomach.
- Shoulder pain: caused by laparoscopic gas and eased by walking.
- Wounds: keep them clean and dry; showering is usually allowed after one to two days as instructed.
- Medications: take your stomach-protection medicine and blood-thinning injections if prescribed to prevent clots.
Movement and Activity
Walking is your best friend at this stage: it reduces the risk of clots, improves breathing and helps relieve gas. Start with short walks every hour while awake, and avoid heavy lifting or strenuous exercise until your doctor allows it. For details, read exercise after bariatric surgery.

FAQs About the First Week After Bariatric Surgery
When can I leave the hospital after bariatric surgery?

The gradual goal is about 1.5 to 2 liters of fluids a day, taken as small, frequent sips throughout the day, according to your doctor’s instructions.
