Why Nausea Happens After Surgery
Nausea is one of the most common complaints following weight loss surgery. The biggest trigger is often overeating, which places excessive pressure on the newly reduced stomach.
Because your stomach’s capacity is significantly smaller, you must stop eating or drinking the moment you feel full. Continuing past this point makes nausea much more likely.
Eating Habits That Increase Nausea
Eating too quickly or swallowing food without chewing thoroughly are common causes of discomfort after a gastric sleeve.
While these habits may have been normal before surgery, they must be adapted to ensure a smooth recovery. As you heal, nausea usually becomes less frequent; however, if poor eating habits persist, symptoms may continue for weeks.
Following Your Nutrition Plan
Your dietitian will guide you through a specific post-surgery nutrition plan tailored to your healing stage. If you experience indigestion or pressure after eating, it is often a warning sign that nausea may follow.
When this happens, it is best to avoid eating for about two hours to let your stomach settle.
If symptoms improve, stick to clear liquids for the rest of the day, such as water, diluted sugar-free fruit juice, or weak herbal tea. Any specific food that caused the nausea should be avoided for one week before being reintroduced.
When Nausea Becomes More Serious
Persistent nausea can lead to fatigue, weakness, dehydration, and even muscle cramps caused by retching.
If these symptoms occur, it is vital to contact your dietitian or bariatric team promptly. Close follow-up ensures you receive the right support to prevent complications and stay on track.
