Feeling hungry all the time in early pregnancy may be caused by the change of hormone level in early pregnancy, resulting in pregnancy reaction, or it may be caused by the increased absorption of nutrients by the fetus after pregnancy. In the early stage of pregnancy, the hormone level of pregnant women changes and the secretion of gastric acid increases. Individuals with different physique and different hormone secretion status will show different pregnancy reactions, some pregnant women will show nausea, vomiting, loss of appetite, acid reflux, belching, etc. However, some pregnant women in the early stage of pregnancy show that they feel hungry all the time and want to eat, they can enhance nutrition in appropriate amount according to their personal taste. Increase the intake of fresh fruits, vegetables and protein-rich foods, such as lean meat and milk. In addition, the embryo’s absorption of nutrients increases after pregnancy, and the pregnant woman’s metabolism accelerates, thus creating a feeling of hunger. It is recommended that pregnant women can eat less and more meals to reduce hunger and supplement nutrition, avoid overeating, chew slowly, and try to choose low-sugar and low-fat foods, such as whole-grain bread, graham crackers and oats, to increase dietary fiber and prevent early constipation. In addition, gestational diabetes and hyperthyroidism may also cause the symptoms of feeling hungry in early pregnancy, so go to the hospital for appropriate examination and treatment if necessary.
