Hungry a little while after eating, mainly consider physiological factors and pathological factors, physiological factors such as too little diet, pathological factors such as gastrointestinal tumors and so on. 1. Physiological factors: when the patient eats too little, only eats vegetables and fruits and takes too little protein and fat food, the gastrointestinal metabolism will be too fast, and the patient will be hungry after being full for a while. 2. Pathological factors: when the patient has gastrointestinal tumor, because the tumor belongs to malignant consumptive disease, the patient will also be hungry a while after being full. When the patient has serious hyperthyroidism, hyperthyroidism will cause the patient’s metabolism to increase, and the patient will also be hungry a little while after he is full. In addition, there may be other reasons for being hungry after being full, so we suggest that patients should go to the hospital in time, improve the examination, clarify the cause of the disease, and then carry out targeted treatment or therapy under the guidance of the doctor.
