 Gastric
Surgery - Nutrition and Diet
Nutrition & Diet
Obesity surgery is usually performed after the candidate has tried other methods of weight
loss without success. However, Surgery in itself is not the full solution. Learning new
eating habits and following the diet correctly will help maintain weight loss over time.
The recommended diet is low in calories and fat. Even small amounts of sweet or fatty foods
could make weight loss difficult. Sweet and sugary foods do not contain vitamins or minerals.
Weight loss surgery reduces the size of the stomach, so it may take a while
to get used to the change required in your daily diet and eating regime. Patients report
a wide variety of complications after surgery. Most of these will go away in time, while
others can be lessened with dietary adjustment.
Nausea and vomiting
These are the most common complications occurring in the first few months after gastric
surgery. They can occur after eating too fast, drinking liquids while eating, not chewing
enough, or eating more than the stomach can hold. It is important to learn to eat slowly
and chew thoroughly. Nausea and vomiting can also be triggered after trying new foods. If
this happens, allow a few days to pass before trying something new. Notify a physician or
contact our nutritionist if frequent vomiting becomes a problem.
Dehydration
It is important to prevent dehydration by drinking enough fluids. Here are some tips:
- Make sure you drink 1½ litres a day.
- Do not drink during meals: do not drink 30 minutes before or after
meals.
- Avoid fizzy drinks like Lemonade, Colas, Fanta etc.
- High calorie drinks such as sugar sweetened drinks, alcohol, etc. may
prevent weight loss.
Adapt your diet in several stages, start with liquids and gradually increase
to small meals of soft, high-protein foods. Each person is different and the dietary limits
will also depend on the type of obesity surgery you have had. Meals should be much smaller
than normal, and foods eaten must be smooth in texture. During all stages of the diet, it
is important to drink enough water.
Different stages:
Liquids
The use of liquid nourishment such as soup, milk, fruit juice, buttermilk, yoghurt, pudding,
Soya deserts: this stage should last for the 1 or 2 weeks after surgery. Also at this stage,
the following may be taken: cornflakes (soggy), yoghurts, mashed fruit, milky puddings,
yoghurt, and soup. Some patients may be OK with toast and biscuits as well. As each person

Ensure that you are getting enough Proteins
Protein is the nutrient used to build new tissue, therefore it is important to intake sufficient
proteins after surgery to ensure proper healing. Protein in the diet helps preserve muscle
tissue, so that weight can be lost. Foods such as meat, fish, eggs, cheese, etc, are high
in protein. It is recommended that you eat fruit at least once a day. Do not eat whole wheat
bread. In the first few weeks, try to avoid raw vegetables, green cabbage, sprouts, peppers,
mushrooms and onions – these are difficult to digest; also avoid spicy, burned or
fatty foods.
Things to remember
- Eat several small portions 4 or 5 times a day.
- It is important to chew food well and eat slowly. Enjoy your food and
concentrate on eating slowly.
- Let your stomach tell you when you have had enough.
- Do not drink during the meals and avoid fizzy drinks.
- Eat healthily. Make sure there is enough variation in what you eat.
Large quantities of high-energy food such as ice creams, chocolates, cakes, etc. are not
recommended.
- The way you eat is just as important as what you eat.
- Changing food habits in combination with physical activity will help
to maintain weight loss over time.
