Diet is the foundation for maintaining human health and life activities, but unreasonable diet can lead to the occurrence of various diseases. If you often lie down when you are full, it will make the food in the body unable to be fully digested and absorbed. These incompletely digested foods will remain in the intestines, gradually decay and spoil, and then produce harmful substances, causing damage to your health.
In addition, long-term full eating and lying can also lead to obesity, hyperlipidemia, hypertension, diabetes and other diseases. Because the human body needs to consume a large amount of energy to digest and absorb food, long-term satiety and lying down can lower the body's metabolic rate, reduce energy consumption, and excess energy will be converted into fat for storage, leading to obesity in the body. And obesity is the foundation of many chronic diseases, so long-term satiety and lying down can seriously harm physical health.
饮食是维持人体健康和生命活动的基础，但是不合理的饮食却可以导致多种疾病的发生。如果经常饱食即卧，会使身体内的食物无法得到充分的消化和吸收，这些没有被完全消化的食物会残留在肠道中，逐渐腐败变质，进而产生有害物质，对身体健康造成损害。

此外，长期饱食即卧还会导致身体肥胖、高血脂、高血压、糖尿病等多种疾病的发生。因为人体需要消耗大量的能量来消化和吸收食物，而长期饱食即卧会使身体的代谢率降低，能量的消耗减少，多余的能量就会转化为脂肪储存起来，进而导致身体肥胖。而肥胖又是很多慢性疾病的基础，因此长期饱食即卧会严重危害身体健康。
