Understanding the new structure of the stomach after sleeve
Each of the types
The nutritional program after sleeve is usually divided into four phases: At none of these stages is it allowed to eat the "whole fruit" raw. But why? Fruits such as pineapples, mangoes, persimmons, and oranges may cause obstruction or irritation of a freshly operated stomach due to their hard texture or insoluble fibers. After sleeve, the stomach is not able to digest such tissues, especially in the first months. Useful example: A person who started consuming raw pineapple two weeks after SLI got stomach blockage and severe nausea; Finally, he was treated by going to the hospital and washing his stomach. Fruits with high sugar such as grapes, ripe bananas, figs, dates and watermelon can cause a rapid increase in blood sugar and a sudden drop after that, which is a phenomenon called "dumping syndrome". Symptoms: Dizziness, shaking, sweating, nausea and pressure drop. Conclusion: Although sugary fruits are natural, they can cause harmful effects due to rapid insulin secretion and limited stomach volume. Fruits such as raw apples, pears, plums, cucumbers and even watermelons may cause gas, bloating and pressure in the stomach. These cases are especially problematic during the soft period and the beginning of the solid food period. Next, you will see a list of fruits that should be avoided for at least the first 3 to 6 months after SLI. This table can also be used as a daily guide: Although some fruits are not completely prohibited, they require proper preparation of the stomach and body system, proper timing and controlled amount. Baked apple without skin Unripe and crushed bananas in the fourth month Sugar-free compote of fruits such as peaches or pears Diluted natural juice without added sugar Important note: In all cases, the amount of consumption should be limited and under the supervision of a nutritionist. Imagine that the patient, who is in the fourth week after SLI, consumes a few grapes and a piece of ripe banana due to a strong desire for sweets. Within half an hour, he may experience symptoms such as heart palpitations, nausea and severe bloating. This actually indicates that the stomach is not ready to digest that sugar compound and special texture. Many patients worry that eliminating fruits will deprive them of vitamins and antioxidants. But there are logical and scientific solutions: Use of multivitamin supplements for bariatric patients Use vegetables for weight loss cooked like carrots, squash or spinach Using pureed fruits such as peaches or cooked apples Drinking natural vegetable juice without sugar No. In the first two months, no fruit should be eaten raw. Only compote without sugar or puree is allowed. Ripe bananas have high sugar and sticky texture that can cause stomach blockage or dumping syndrome. It is better not to consume raw apples at least until the end of the fifth month after the sleeve. In the fourth month, you can eat cooked apples without the skin. Only if the juice is completely natural, without added sugar and diluted with water, in small quantities and carefully. Vitamin supplements, cooked vegetables and sugar-free compote of light fruits can be good alternatives. The period after sleeve surgery is a golden opportunity to change your lifestyle. Adherence to nutritional tips - especially avoiding heavy, sugary and flatulent fruits - will not only help the health of the digestive system, but also prevent serious complications. Finally, with patience, training and following expert advice, you can go through the path of weight loss with health and satisfaction.Steps of diet after sleeve surgery
