Is stomach disease caused by what we eat? Focus on these 3 key elements for stomach health. Eating is something we do every day, with three meals a day, each with a healthy proportion. During the work week, we might not be able to rest after meals due to work or other reasons. But on our days off, we can completely relax. After a hearty meal, we can even get a good night's sleep. But why do people say that lying down to rest after a full meal will affect digestion and even cause weight gain? Is there any truth to this? Today, we'll reveal the truth. Many people feel sleepy after eating. At this time, they want to lie down and rest. The reason for this phenomenon is actually related to orexin. When we eat a full meal, the level of orexin in our bodies changes. When it decreases, it plays a role in regulating sleep, thus making us sleepy. If people with high blood sugar, such as diabetics, may have eaten carbohydrate-rich staple foods during meals, which may also cause drowsiness. So, can you lie down to rest after feeling sleepy? If you don't have gastroesophageal reflux, you can. People with gastroesophageal reflux disease (GERD) may experience irritation and heartburn if they lie down due to their condition. If you don't have GERD, lying down to rest is fine. This allows your digestive system to work properly, preventing weight gain and maintaining proper digestive function, provided you eat a moderate amount. However, if you've eaten a large meal, it's recommended to take a walk first. This aids digestion and can also energize you. For those who don't nap, this can improve your afternoon work performance. This is better than playing games immediately after eating and is also a good way for obese individuals to control their weight. Of course, strenuous exercise after meals, such as running, sit-ups, or skipping rope, is not recommended. These activities can impair digestion and cause side stitches. Instead, a leisurely walk is preferable, especially at midday when the sunlight is still plentiful. Uncontrolled eating and irregular lifestyle are related to this condition. These factors gradually increase coldness in the body, leading to decreased gallbladder contraction function, reduced bile excretion, and even reflux into the stomach through the pylorus, where it interacts with stomach acid and damages the gastric mucosa. In more severe cases, it can even reflux into the throat and mouth, damaging their mucosal barriers. Reduced bile makes food difficult to digest and absorb. Since fat metabolism mainly relies on bile, irregular fat metabolism is also a problem. It's not hard to see that gallbladder problems are not good. Many people are experiencing these symptoms, and the trend is becoming more pronounced among younger people. This needs attention. In addition to making some adjustments, when you have free time, you can go to the nearby countryside to pick some bitter herbs and cook them into a soup with brown sugar. By regulating the gallbladder, these symptoms will gradually improve, and your health will naturally improve. With a controlled diet and moderate exercise, you can definitely make a difference. Walking in places where the sun is not too strong can also help the body synthesize vitamin D and promote calcium absorption. After walking around, those who have eaten too much can lie down and rest for a while. A 15-minute nap will be very good for their work performance in the afternoon.
