There is no obvious hunger, but the desire to ingest food may be a pregnancy reaction after pregnancy. In early pregnancy there is a rapid increase in blood HCG and the body may experience nausea, vomiting or increased eating because it is not adapted to this change, with a relatively large individual difference in which symptoms occur. If you have had intercourse or your period is delayed, you can check for chorionic gonadotropin or a gynecological ultrasound to determine if you are pregnant. If pregnancy is ruled out, pathological changes such as gastritis, hyperthyroidism or diabetes are considered. In the case of gastritis, some people can show increased appetite or hunger-like pain; hyperthyroidism can easily induce hunger because of increased energy consumption; diabetes can induce blood glucose deficiency because of glucose excretion from urine, which stimulates the brain nerves to produce hunger; gastroscopy, thyroid function and blood glucose tests can be done to rule out the disease.
