Pre bariatric surgery diet
Bariatric surgery is a life-saving procedure. You will lose weight. You will reduce your co-morbidities. You will feel more confident and look better. However, to be long-term successfu, you have to change your diet. This sounds simple, but it’s not. Be prepared for challenges. You’ve spent much of your life building and reinforcing bad eating habits. This is one of the reasons why you are now qualified for bariatric surgery. This pre-operative diet aims to prepare you for your planned bariatric procedure and is essential to reduce the size of your liver and amount of fat surrounding internal organs. This is important for the safety of your surgery. The sooner you start, the better your results will be.
Before obesity surgery, it is essential for you to follow a a calorie-restricted diet. The energy value of this diet needs to stay between 1000 – 1500 calories per day. The last 5-7 days before the procedure, please stay only on a liquid diet in order to better prepare your stomach and liver for bariatric surgery. Avoid alcohol. All beverages and liquids should be sipped very slowly. Beverages should not be consumed with meals, you should wait at least 30 minutes after a meal before consuming any type of liquid. Please spread food and drinks throughout the day at regular intervals. Separating your liquids and solids applies after surgery, but it’s a good practice to start developing this habit already.
If you currently control diabetes with medication, this will need to be adjusted during the pre- operative
diet. Please speak with your doctor, you may need to reduce your diabetes medication parallel to reducing
your food intake. Blood sugar level should be controlled more regularly to avoid hypo-glycemia. If you
control your diabetes by diet alone, you don’t need to be worried about your blood sugar.
Additional Pre Surgery Notes:
- Talk to your doctor about stopping certain medications prior to your surgery.
The following medications are typically stopped 5-7 weeks before the treatment.
Coumadin, Warfarin, Acenocoumarol, Marcumar, Xarelto, Pradaxa, other anti-coagulation medications (blood thinners) like: Aspirin, Clopidogrel, Plavix, Brilique, Motrin, Advil, Celebrex and any other NSAIDs
- If you have sleep apnea and use a CPAP machine, please bring it with you to Hospital
- Stop smoking. Smokers have an increased risk of blood clots and complications during and after the
7-14 days before the procedure, the compulsory preoperative diet should include:
- Only sugar-free and no caffeinated beverages, no fizzy drinks, no alcohol
- Fat low natural yoghurt, milk, smoothies, milkshakes
- Soup with no solid pieces of food
- Cooked vegetable
- Fruits juice (low in sugar)
- Fresh vegetables and fruits
- One daily steam cooked fish or dairy
- Minimum of 2 liters of fluid per day at regular intervals
- 2-3 times per day Protein shakes/ Nutri-drinks as replacement for meals

Post bariatric surgery diet
You’ve just opened the door to a new, healthy life – congratulations!
You’ve chosen the most effective means of treating overweight problem and obesity related diseases, creating a sustainable weight loss. It is time now to move to the next stage – amending your lifestyle. The essential change you will be making is correcting your diet and the amount of food you can eat.
There is no room for cheating anymore. Abiding by the appropriate diet, especially the initial 4 weeks, will help you to prevent the postoperative complications. That is why, it is extremely important that you take the instructions seriously.
Non-compliance to your postoperative diet may result in diarrhoea, dehydration, constipation, bowel obstruction, or a very serious gastric leak.
Here are some basic rules for the first 6 weeks after your surgery:
- Consume food once it’s cooled down to a moderate temperature
- Do not consume carbonated drinks
- Take small portions (150g) meals every 2-4 hours
- Chew thoroughly
- Drink fluids 8-10 times per day, 100 ml – 150 ml each portion
- Drink no later than 30 min. before meal and not earlier than 30 min. after meal
- Avoid food that are too sweet, spicy, sour, greasy, hot or cold
- Consume slowly and stop eating as soon as you start feeling full up, even if it means leaving your food on the plate
- Avoid dishes with asparagus, spinach, leafy, cauliflower, broccoli stems, green beans, leeks, cabbage and onion
- Avoid products of small size which may be swallowed as a whole bit, for instance: broad beans, cherries, nuts, etc.
- Cancel the consumption of high energy products and replace them with a variety of low-calorie products to provide your body with a large amount of vitamins and minerals
- Take your medication and vitamins according to the recommendations
- The use of thromboprophylaxis reduces the risk of embolic complications
In case of adverse effects, like vomiting after meal, indigestion or nausea, ask yourself the question:
- Did I eat too fast?
- Was the meal sufficiently well chewed?
- Did I eat too much ?
- Did I drink with the meal?
- Did I drink too soon after meal?
- Did I lay down too soon after meal?
Your Diet – Weeks 1 to 5 and after:

Soft Blended Food
The third week brings some real food into your diet. But the good news is, you can start adding some “real” food to your diet. Nevertheless, the food must still be eaten soft or mixed. You still need to be careful to limit sugar, fat and salt.
The goals for week 3 include:

- Eat slowly, chew your food throughly
- One at the time and cautiously introduce new food slowly
Food might taste different and is tolerated differently than before the surgery. Give your organism some time to react to each new food. Doing so, will enable you to determine food that you
tolerate and food that is upsetting your stomach or cause diarrhoea or winds.

The first three weeks of the diet are behind you. Now it’s time to start introducing new dishes.
