Nausea and Vomiting After Weight Loss Surgery.
Nausea and vomiting can occasionally occur during the first weeks or months after bariatric surgery as the body adapts to changes in the stomach and eating patterns. While this is usually temporary, understanding the causes and how to prevent it can make recovery more comfortable and safe.
Common Causes of Nausea and Vomiting
-
Effects of anaesthesia or post-surgery medications
-
Eating / drinking too much or too quickly
-
Insufficient chewing of food
-
Food intolerances
-
Progressing through diet stages too rapidly
-
Drinking and eating at the same time
-
Lying down too soon after meals
How to Prevent Nausea and Vomiting
To reduce discomfort and support healing, it is important to follow post-operative guidelines carefully:
-
Stay well hydrated throughout the day
-
Chew food thoroughly until it reaches a smooth, puréed consistency
-
Eat slowly while sitting upright
-
Avoid high-fat, sugary, and highly processed foods
-
Do not drink liquids during meals
-
Keep portions small and controlled
-
Avoid lying down for at least 30–60 minutes after eating
-
Progress through diet stages only as advised by your medical team
