Stomach Response To Food Intake

Our stomach is made up of folds or mucosal lining called ‘Rugae’ which permits expansion and contraction as a direct response to our food intake. In general, the food you eat gets chewed and swallowed through your mouth and passes through the esophagus into your stomach to be broken down by acids.

The food moves relatively rapidly through the sleeve and into the intestinal tract. As you continue to eat, more food enters the stomach to be processed. Food passing through the stomach and intestine triggers stretch receptors release a chemical called cholecystokinin (CCK) to signal your brain to send signals you experience as feelings of fullness or satiety. In overweight people, the hunger and fullness signals (CCK mechanism) may not function properly.

When your stomach is overstretched, you are constantly overeating. Since it takes a longer time for your stomach to fill up and you will eat larger quantities of food before your brain can signal satisfaction and fullness.

Preventing Your Stomach Stretching

  • Take small bites
  • Eat slowly, pause between bites and chew your food to enjoy the taste.
  • Be cognizant of your body’s response to being satisfied.
  • Use a smaller plate as smaller plates hold less food.
  • Avoid overeating
  • Portion Control
  • Do not drink when you eat. Stop all liquids thirty minutes before and thirty minutes after. This will allow fluids to not to take up space for nutrient-dense foods or push the food through faster.
  • Stop mindless snacking; the only snack when you are physically hungry and chose whole food options like nuts, avocado, boiled eggs, vegetables, and fruits
  • Use healthy recipes that are suitable for people who have gone through sleeve surgery.
  • Remember progress, not perfection; stay focused on your “why.”
