Nutrition for Bariatric Surgery Patients:

Bariatric surgery, especially gastric sleeve, and gastric bypass are very effective methods for the long-term treatment of obesity.

These procedures are increasingly becoming popular because they lower obesity-associated complications such as sleep apnea, diabetes, hypertension, dyslipidemia, and ASCVD (atherosclerotic cardiovascular diseases).

However several nutritional deficiencies after surgery are frequent and have a variety of reasons.

Nutritional deficiencies are common in obese patients and individuals who are on a weight loss diet, especially the crash weight loss diet.

Following surgery, the risk of insufficiency is increased by decreased food intake, inadequate diet quality, altered digestion and absorption, and noncompliance with supplementation schedules.

To overcome these deficiencies that are common in post-bariatric surgery patients, it is recommended to add a certain amount of micronutrients and macronutrients to their daily meals.

Lunch is one of the vital options to add a good amount of calories to fulfill the basic needs of individuals after such an invasive surgery.


How to Plan Your Diet Postoperatively?

 The first 8 weeks after a bariatric surgery are very crucial. It is recommended to plan post-operative meals according to the following table:

Post-Meal Discomfort After Gastric Bypass:

Postmeal abdominal discomfort is common after gastric bypass and gastric sleeve surgery.

These include nausea, bloating, diarrhea, abdominal pain, fatigue, tachycardia, and hypotension.

Most symptoms develop as a result of the rapid carbohydrate influx into the intestine resulting in fluid shifts. This leads to hypotension after meals.

In addition, the rapid absorption of carbohydrates leads to insulin production causing hypoglycemia.

Collectively, these symptoms are called the “Dumping Syndrome

Certain eating habits e.g.; fast eating and consumption of large amounts of foods, result in an increased postprandial satiety signal production and therefore false signals being sent to the brain.

Also, postprandial discomfort often occurs due to the consumption of fatty meals.

It is recommended that the use of a high-fiber diet and a diet with balanced amounts of protein, carbohydrates, and fats would be helpful postprandially to recover the health and multiple deficiencies.

A balanced and fiber-rich meal may also reduce some of the symptoms of abdominal discomfort after meals.
