When these muscles are weak, the pressure on the backbone is greater and causes discomfort.
When these muscles are strong and toned up, the baby’s weight exerts less pressure on the backbone and no backache occurs. Bad posture also causes backaches.
A good posture is simply good balance of the different parts of the body. As you stand, gravity has the effect to constantly pulling you down to the floor, but you remain upright against the force of gravity.
Typically in pregnancy, one stands with one’s bottom out and the hollow of one’s back exaggerated. Instead, one should learn to stand straighter. Keep your bottom tucked in and use your abdominal muscles to support the extra weight, instead of overstretching them by just letting them go.
You will be benefited by looking and feeling better, and suffering less from backache and tiredness. Also, your stomach will flatten faster after delivery. Tightening your abdominal muscles is not harmful to the baby at all.
The baby is comfortably cushioned in the uterus with amniotic fluid; it gets its supply of oxygen through the umbilical cord; and makes place for itself by nudging the intestines, bladder, liver and other organs away.
To relieve backaches, pull your tummy in, tuck your bottom in and straighten the length of your backbone against wall. Rest should also help soothe your backache.
Do not let yourself get overtired. Lie down more often. When lying on your back with legs straight, place a small pillow or folded towel in the hollow of your back. Or else, lie with your legs bent at the knees, feet flat on the floor. As you lie like this, flatten the hollow of your back against the floor.
If you prefer to lie on your side, place pillows as high as your hips. Bend and place the leg on the upper side, bent at the knee, on top of the pile of pillows. Place the arm on the underside, towards your back, along the length of your backache.
Severe low backache may sometimes be caused by lack of calcium, or by the baby’s position. If it is due to lack of calcium, the doctor would recommend supplementary calcium.
Upper backache may be caused by poor posture or heavy breasts. Correct your posture and wear a good well-fitting cotton bra, adjusted at the straps to carry the weight of the breasts.
