lightening

[lī′təning]
Etymology: AS, leoht, light
a subjective sensation reported by many women late in pregnancy as the fetus settles lower in the true pelvis, leaving more space in the upper abdomen. The diaphragm, no longer restricted by the fundus of the uterus beneath it, can move down more fully during inspiration, allowing deeper breaths. The stomach, too, is less compressed, so the woman can comfortably eat more food at each meal. Urinary frequency occurs as the fetus drops. The profile of the abdomen changes with lightening, because the round, full uterus is visibly lower. The baby is then said to have "dropped."
The descent of the foetus, resulting in decreased fundal height, an event that occurs about 2 weeks before labour, caused by physiologic changes of the uterus; lightening is characterised by an abrupt sensation of ‘lightness’ or relief from the weightiness felt by the mother which corresponds to the drop of the baby’s head into the pelvis

light·en·ing

(līt'ĕn-ing)
Sensation of decreased abdominal distention during the later weeks of pregnancy following the descent of the fetal head into the pelvic inlet.

lightening

The sense of relief felt, during the last three or four weeks of pregnancy, with the descent of the presenting part of the fetus, usually the head, more deeply into the pelvis so that the womb occupies a smaller volume of the abdomen. This reduces abdominal distention and occasions some easing of breathing and general discomfort. Lightening is usual in first pregnancies but may not be apparent later.
