Healthy diet after surgery
Especially in the first 8 weeks after surgery, you should change your eating habits to avoid pain, vomiting and wound dehiscence in certain conditions and of course lose weight.
Changing eating habits may also help to prevent gastric obstructions. Swallowing large bites may hinder the passage of food through the intestines. To decrease the risk of intestinal obstruction, it is important that you eat slowly and swallow after good chewing. Your new slogan should be: “slow, small, moist and easy”.
Stop eating when you are full
Just one more spoon may lead to vomiting and stretching of your stomach wall. Focus on the signals of your body not the food on your dish. The signs of satiety may be different from the signs before surgery. Some signs – even though less obvious – showing that your stomach is about to be full are: Pressure or feeling of fullness just under your chest cage in the middle of your abdomen.
- Nausea, vomiting or heartburn. A few minutes after you are really full, you start to feel satiety. You may try the following to find the right portion size: Measure 30 cc of water and drink it and wait a couple of minutes. If you feel full with this volume and you are comfortable, measue your meals similar to this volume. This will prevent the dilatation of your stomach sac and the emergence of discomfort due to overeating.
Tips for general mealtimes
- Take 30-45 minutes for each meal. Take your time to chew your bite well. If you use a dental plate, you have to eat purees or soft foods. Learn to eat more slowly and consciously to allow your body to feel satiety and digest food better. If you eat too fast, you may overeat and not chew sufficiently, and this may cause vomiting.
- Explain to your friends and family why you should eat slowly: Thus, they will not expect you to eat faster.
- Take small bites. You may use a saucer as a visual aid instead of a regular plate for portion control.
- You can use small forks and spoons to determine the correct portion.
- Only eat at mealtimes recommended by your health team. “Snacks” between meals, which are not recommended by your health team, or eating small “snacks” here and there will have a negative impact on your weight loss process and prevents you reach your targeted weight.
- Do not consume fluid while eating solid food. Do not drink fluids 30-45 minutes before and after solid food intake. Taking liquid and solid food together may cause nausea and push food faster through the stomach and lead to overeating.
- Just eat the best food. After all, if you must eat less then eat the best, isn’t it?
What you have to eat after surgery
Proteins
Proteins are essential for your muscles, organs, heart, and brain. Protein is necessary for the repair and regeneration of worn or damaged tissues. In addition, proteins help to fight infections.
A small stomach sac reduces the gastric capacity to a small volume so that protein-containing food should be consumed carefully in every meal. Nevertheless, taking proteins adequate to manage body functions is critical.
The minimum daily protein intake should be at least 60 g in females and 80 g in males.
In the first 6 months, your target should be at least 60 g per day. After three weeks, if you have not taken enough protein, your body will remove protein from your muscles, which are a protein source themselves. This will lead to nausea and fatigue.
In the beginning, it is easy to follow how much protein you are taking when you are consuming protein drinks. Thereafter, while you start to eat normal food, it may be more difficult to follow your protein intake. Use the food labels as a guide. If you want to add drinks or protein bars to liquid protein mixtures, be careful. These types of products contain high amounts of sugar and calories and have a bad taste.
In certain cases, your dietitian may recommend taking more protein.
Vitamins
After bariatric surgery, the created small stomach sac will not allow you to eat enough for an adequate nutrition. In addition, malabsorption as an adverse effect of surgery reduces the capacity of the body to process vitamins and minerals. To get enough vitamins, in line with the recommendations of your health team you have to take a high-dose multivitamin and mineral supplement every day for the rest of your life. For instance, you may need to take the following supplements:
B12: B12 deficiency may develop very fast, but there are few symptoms despite its serious risks. Animal products (meat, milk, fish, poultry) contain high amounts of B12. Let your vitamin levels be checked regularly by your health team.
Calcium: We recommend that you take calcium supplements every day. Calcium is essential for bones, teeth, and neural conduction. Many individuals do not get enough calcium in their diet.
Iron: Many patients, especially females should take iron supplements to maintain an adequate iron depot and prevent iron deficiency anemia. Iron exists in many different forms. The most common form may lead to constipation. Ferrous fumarate may cause less constipation.
Additional vitamin supplements can be prescribed according to your needs. Other medications will be prescribed by your health team.
Patients who have undergone weight-loss surgery and still have a gallbladder may need to take certain medications during the period of greatest weight loss to minimize the risk of gallstone formation. Consult your surgeon to learn whether this treatment is necessary for you or not.
Liquids
You should drink 1,5-2 liters of water between meals. Among the recommended drinks you will find water, unsweetened, low-calorie, and noncarbonated beverages.
- Avoid carbonated beverages: Following swallowing, a cold fluid warms up and releases gas, which stretches and consequently expands the stomach sac. This creates an undesired tension and causes the anastomosis to stretch.
- Do not drink fluids 30 to 45 minutes before and after meals, as it may stretch the stomach sac and provoke vomiting.
- Drink fluids in slow and careful sips.
- Drink small sips regularly during the day to avoid dehydration.
- High-calorie drinks like milkshakes, carbonated water and liquors are not allowed. High-calorie drinks usually have poor nutritional value and contain simple sugars.
NOTE: If the color of your urine is dark or you have a dry mouth, it means that you are not drinking enough fluids.
