There is no difference between food stagnation (the accumulation of food in the stomach due to indigestion) and food accumulation, both of which belong to the Chinese medicine point of view of the identification of the meaning of food stagnation and inability to digest. Food stagnation is caused by stagnant food in children over one year of age, which stagnates in the stomach for a long time, thus causing indigestion. The symptoms of food accumulation and food stagnation are the same, and clinically, they mainly manifest as abdominal distension, abdominal pain, vomiting, diarrhea, and loss of appetite. To deal with food accumulation or food stagnation, the first thing you need to do is to improve your diet. You should pay attention to a light diet and reduce the amount of food you eat, especially reduce the intake of greasy food. In addition, it can be regulated by taking medicines to eliminate food and strengthen the stomach (to promote food digestion and strengthen the function of the stomach and internal organs), such as tablets for strengthening the stomach and eliminating food and pills for preserving and strengthening the stomach. If your child develops symptoms of overeating or food accumulation, it is recommended that you seek medical attention for scientific treatment under the guidance of your doctor.
