In the early stage of pregnancy, pregnant mothers most commonly experience early pregnancy reactions such as nausea, vomiting, fatigue, gastrointestinal discomfort, etc. Some pregnant mothers also feel particularly hungry easily. First of all, after pregnancy, the body automatically gives part of the nutrients to the fetus in the womb and stores more nutrients for the growth and development of the fetus. In order to ensure the basic nutrition supply, pregnant mothers achieve sufficient nutrition composition by actively taking in nutrients outside the body, so the body gives pregnant mothers a kind of hunger reflex, so pregnant mothers are easily hungry in the early stage of pregnancy. Moreover, due to the increase of estrogen level, the cells of reproductive organs and breast and other tissues proliferate and hypertrophy, which need more nutrients to support the growth of these cells. At the same time, the metabolic level of the body increases after pregnancy, which leads to the increase of the body’s daily consumption, including the role of progesterone, the body will also have a certain degree of effect of raising the body temperature, which will also accelerate the body’s basal metabolic rate and easily produce hunger. Finally, due to the existence of pregnancy reactions, such as child drama, vomiting, etc., some of the food consumed by the pregnant mother itself is not absorbed, the body needs less nutrient intake than before, and the pregnant mother will also feel hungry. Therefore, it is normal for pregnant mothers to feel hungry in early pregnancy. It is recommended that pregnant mothers eat less and more meals to ensure normal nutritional intake, and for pregnant mothers with heavy early pregnancy reactions, they can eat a little bit, and their symptoms will gradually ease as the pregnancy week grows and the fetus gradually increases and stabilizes.
