For pregnant women with hyperemesis gravidarum, doctors recommend oral medication. However, pregnant women must weigh the advantages and disadvantages of taking the drug, especially for women in the first trimester of pregnancy, because the first trimester is a golden period for the baby’s growth and all organs are in an important growth period, especially the brain and nervous system, so oral aspirin is not recommended in the first trimester. Oral aspirin is also not recommended for pregnant women who are about to give birth during the first 3-4 weeks of labor to avoid hemorrhaging during labor and increasing the risk of bleeding in the mother and child. If aspirin must be taken, it is recommended that the appropriate amount be given after consultation with an obstetrician and cardiologist.
