Pregnacare A-Z Of Pregnancy And Nutrition – What Does The Letter B Stand For?

Back Pain

What Causes Back Pain In Pregnancy, And What Can I Do To Relieve It?

What causes back pain in pregnancy?

Back pain experienced by pregnant women is caused by the ligaments between the pelvic bones softening and joints loosening in preparation for the baby’s passage through the pelvis. This movement can cause considerable discomfort on either side of the lower back, often with walking, and especially when going up and down stairs.

During the second trimester, the uterus becomes heavier and changes the woman’s centre of gravity. Gradually - and perhaps without being aware of it - women begin to adjust their posture and the way in which they move. These compensations can result in back pain, strain or other injury. The separation of the muscles along the front of the abdomen during pregnancy may also contribute to back pain during pregnancy. These two parallel sheets of muscles run from the rib cage to the pubic bone. As the uterus expands, they sometimes separate along the centre seam, which can make back pain worse.

Careful lifting and carrying during pregnancy is important to prevent injury.

Birth Weight

Your Baby’s Birth Weight

Your baby's birth weight

The average birth weight in the UK is 3.5kgs (7.6lbs), but this can be reduced if you are expecting your first child, or if your baby is a twin or triplet.

Your midwife will check the size of your baby by measuring your bump at intervals throughout your pregnancy. They may need to arrange an ultrasound scan to check the health of your baby if they measure smaller than expected.


Bloating During Pregnancy

Bloating during pregnancy

The sensation of bloating occurs during pregnancy because of hormones that slow your digestion and the pressure of your growing uterus on your stomach and intestines. Eating plenty of fibre and drinking adequate amounts of fluid may help to alleviate this.

Body Mass Index

Body Mass Index And Pregnancy Weight Gain

There are no UK guidelines for weight gain in pregnancy but some studies have provided the information in the table below. You should not try to lose weight during your pregnancy but it is also important not to put on excess weight either.

Body mass index is a measure of weight in relation to height. It is calculated using the following equation.

BMI = weight kg ÷ (height m)2

BMI Chart

The average pregnancy weight gain for women in the normal weight category is 10-12kgs or 22-28lbs. Generally, women gain 1.1-4.4lbs during the first trimester. During the second and third trimester, women of a ‘normal weight’ will gain an estimated 1lb a week, with obese women gaining 0.5lb.

Bowel Movements

How Will My Bowel Movements Change During Pregnancy?

Constipation (difficulty passing bowel movements) is common in pregnancy due to hormones slowing the gut and the physical pressures of the baby. After child birth some women may experience bowel problems. An adequate fibre and fluid intake should help with this, but see your GP if you have any concerns.


Breast-feeding Your Newborn Baby

Breastfeeding your newborn baby

Breast milk is the best possible nutrition for your baby. During breast-feeding, your baby is entirely dependant on you as their only source of nutrition. By ensuring your diet contains adequate levels of specific vitamins and minerals, your baby will receive all the nutrients they need. Some women choose to take a multivitamin and mineral supplement that is specifically designed for pregnancy and breast-feeding, for extra peace of mind and to safeguard their own nutritional requirements, such as Vitabiotics Pregnacare.
