Fetal hiccups are usually physiologic and may be caused by normal swallowing of amniotic fluid by the fetus, and usually do not require special treatment. If the hiccups are caused by other pathological factors, prompt medical attention is needed.
Fetal hiccups are usually a normal part of pregnancy and occur regularly every 2 to 3 seconds. It is a sign of increased respiratory capacity of the fetal lungs and often occurs after a pregnant woman has eaten a meal.
Fetal hiccups and fetal movements are sometimes easily confused. Fetal movement is generally more active between half an hour and an hour after eating, and manifests itself as a series of irregular movements of varying intensity, which may be manifested as writhing, stretching of limbs, or kicking of the legs, etc. However, the strength and amplitude of fetal movement are generally greater than that of fetal hiccups.
Experienced pregnant women can sometimes use the hiccups to self-monitor changes in fetal position.
Fetal hiccups are usually not a cause for concern and should be checked regularly. If other pathologies cannot be ruled out as the cause of frequent hiccups, prompt medical attention is recommended.
