There is a myth that when you eat a lot, you get more stomach and eat more. This myth is erroneous information from the fact that the stomach has elasticity. The stomach may swell up to 5 times depending on the amount of food you eat. However, the size change is temporary. After digesting the food, it returns to normal size. The size of the above may vary slightly from person to person, but the permanent size does not change at the end of the growth. However, once you have over-eaten in your experience, you may have felt like you have more food. This is not because the size of the stomach actually changes, but to the effects of hormones.
The hormone that regulates the diet is called 'ghrelin', also called fasting hormone. If you eat a lot of repeated ghrelin before you are more secreted, you feel a big hunger, you will not be satisfied with small food. In addition, eating a diet 'YY (PYY3-36)' hormone secretion is releasing the hunger is easing hunger, repeated overeating and overweight people in this peptide YY secretion is less. Even if overeating does not increase stomach, it is not good to repeat overeating. Overeating reduces the rate of digestion and increases the amount of excrement, and too much can cause gastrointestinal disturbances. Obesity due to overeating as a result of weight gain, hypertension, diabetes, hyperlipidemia and metabolic syndrome is likely to occur. Drinking lots of water helps prevent overeating. Leptin, a hormone that makes us feel embarrassed, is secreted from 20 minutes after meals.
