Pregnancy weight gain. You are more likely to get stretch marks if your weight gain is more than average in pregnancy. Most women gain between 10kg and 12.5kg (22 and 28lb) in pregnancy, although weight gain varies a great deal from woman to woman. How much weight you gain depends on your weight before you were pregnant.
What causes stretch marks? Stretch marks are caused when the skin rapidly stretches as a result of sudden growth or weight gain. The stretching causes the middle layer of skin (dermis) to tear, allowing the deeper skin layers to show through, forming stretch marks. The dermis contains strong, inter-connected fibres that allow your skin to stretch as your body grows.
