Gastric bypass surgery can lead to complications such as dehydration, malnutrition and rapid emptying syndrome. To avoid them, you will have to eat and drink carefully. Read below to find out what you can do.

I carried a daily record of food and beverages. Write down everything you eat, including condiments such as ketchup sauce and chopped pickles; Also write down all the drinks you drink, including water. This will help you keep track of what you consume.

Keep your hydration. Lack of sufficient fluids can cause dehydration, which has symptoms such as extreme thirst and dark yellow urine. Your new stomach can hold only a small amount of liquid at a time, so it is important that you drink sips during the day. Drink at least 6 to 8 cups (1 cup equals 8 ounces) of sugar-free liquids every day. Drink slowly. Do not use straws or drink directly from bottles, as this can produce painful gases. Avoid drinks with bubbles for the first few months, as they can also produce gas. Do not drink anything before, during or after meals, as drinks can interfere with the proper digestion of food.

Eat enough protein. Protein is a very important part of your new diet, as it produces a feeling of fullness and maintains normal body function. After surgery, your surgical team may ask you to take protein shakes. You will have to eat high protein, low fat foods with each meal. Slowly increase the amount of protein you eat until you eat 60 to 100 grams a day. If you eat meat, make sure it is not hard or full of fat or connective tissue. To avoid clogging the stoma, do not swallow the meat if you can not chew it thoroughly. Avoid protein foods high in fat such as sausages, bacon, hotdogs and fatty meat for hamburgers. Eat foods that are high in protein and low in fat, such as:

• Chicken and turkey (breast)
• Fish and seafood (not breaded or fried)
• Eggs, egg whites and egg substitutes
• Dairy products (milk, yogurt, cottage cheese) low-fat or fat-free
• Soy milk and tofu
• Canned tuna and salmon
• Peanut butter (peanut)

Although beans, lentils, vegetables and nuts also contain protein, they do not possess all the amino acids present in animal protein. You can eat these foods but you must do so in addition to consuming the other animal proteins indicated above. If you have difficulty meeting your daily protein needs, you may have to take a protein supplement. If so, make sure the supplement does not contain sugar (or lactose, if you are lactose intolerant).
Not getting enough protein can lead to a lack of protein. Symptoms of inadequate protein (and caloric) intake include excessive hair loss, dry skin, fatigue and feeling cold when no one else feels cold. Some of these symptoms are common after a gastric bypass. You can minimize them by concentrating on protein consumption. These symptoms should disappear 4 to 6 months after the operation.

Reintroduce the food little by little. After the operation, certain foods such as meat, fruits, vegetables, breads, pasta and rice are more likely to cause pain, nausea vomit or blockage Try adding these foods to your diet one at a time. Chew food well. If you can not tolerate a food, try it again 1 to 2 weeks later. Also, be careful with dairy foods as they may cause cramping, swelling or diarrhea after the operation. This is because your body may lose the ability to digest lactose after the operation. Try the lactose-free versions of dairy products; You can also try taking lactase pills with dairy products.

Avoid the rapid emptying syndrome. After a gastric bypass surgery, a condition called rapid emptying syndrome may occur. This syndrome can appear between 10 and 30 minutes after consuming sugary foods or even up to 2 to 3 hours later. It can also occur after eating too fast or in excessive amounts at once. Some of its symptoms are intestinal colic, nausea, vomiting, diarrhea, accelerated heart rate, dizziness, flushing and sweating. The symptoms usually disappear in 15 to 30 minutes or even faster if you drink 1 cup of water in sips. Maybe I want to rest later. A few hours later you may have more symptoms, such as a low blood sugar level that can cause tremors and anxiety. Sugar is the most common cause of rapid emptying. You can prevent rapid emptying syndrome if you keep a low-sugar diet, where you avoid:

• Sugary foods such as candy, chocolate, sweetened chewing gum, sweetened yogurt (which can also be frozen), sweetened cereals, baked candies, ice cream and dried fruit
• Sugary drinks such as soda pop, fruit juice and coffee and tea with sugar or flavored syrup
• Sugary condiments such as jam, honey and syrup

Read the labels on food and beverages to see if they contain sugar. Look for sugars, sweeteners, syrups, cane juice, agave, maltodextrin and words that end in “osa”. You can substitute sugar for artificial sweeteners such as aspartame, saccharin, stevia and sucralose.

Take vitamins and mineral supplements. After the operation, your body will not be able to absorb all the vitamins and minerals that you need from the food symptoms of lack of vitamins and minerals in the body (malnutrition) are tiredness, swelling of the ankles or excessive loss of hair. Over time, deficiencies of vitamins and minerals can cause serious health problems. To avoid this, it will be necessary for you to take vitamin and mineral supplements every day for the rest of your life. Some of the supplements are:

• A multivitamin with chewable minerals (1 to 2 pills a day; take them just before eating)
• Calcium citrate with vitamin D (1,200 mg daily, take it just before eating)
• Other supplements, such as vitamin B12. or those indicated by your health care provider.
