Nutritionally, hunger refers to a state in which the body does not receive or is not adequately supplied with the oxygen, heat or nutrients it needs for its own nutrition. The general term hunger mainly refers to the lack of caloric energy. Adequacy of caloric energy is the basic sign of “hunger” and “fullness”. Anyone can understand a child’s diarrhea caused by eating too much. As the saying goes: “If you eat more, you will have more diarrhea”. How can hunger also cause diarrhea when it generally means eating less? The cause of hunger-induced diarrhea may be due to an increase in bowel movements, so the number of stools increases. When considering that your child’s diarrhea may be caused by hunger, you can increase the amount of food from a small amount. If the number of stools does not increase after the increase in food intake, you can continue to increase the amount. Even if the stool increases by 1-2 times, it can still be persisted. After 3-4 days of observation, the number of stools does not increase again, you can increase the amount again. This is how to observe and increase the amount until the diet can meet the needs of the baby.
