The magnitude of the problem

Perhaps 20-30% of all women spot, bleed or suffer cramps during their first 12 weeks of pregnancy, and about 10% miscarry. This figure may be an underestimate, because there are a number of women who miscarry an early pregnancy unknowingly, thinking that their period has been late or heavy. Thus, it is acute common for women to have one miscarriage during the first twelve weeks of their pregnancy. This mostly happens by chance and is not a sign that they have a health problem because most of them will probably have a healthy baby the next time they get pregnant without any treatment.

If, however, a patient has had two or more miscarriages consecutively, this is called repeated or habitual abortion. Now, although the risk of miscarrying again does increase, this risk is still quite small, and go up from the 15% risk a normal woman has to 35% - which still means there is a 65% chance that these will not have a miscarriage again.

Fact and fiction

  • Most women who miscarry do so only once. Their risk for miscarrying again is not increased and is the same as that of a normal woman's - about 15%
  • Women who are over 35 years of age are more liable to miscarry
  • There is an old saying that you cannot shake a good apple off a tree. Travelling, lifting weights and sex do not threaten a healthy pregnancy.

If you've had a previous miscarriage, it is very normal to be frightened and worried during your next pregnancy. It is important to understand that exercise, working and intercourse do not increase the risk of pregnancy loss. Likewise, staying at home and resting in bed probably do not prevent miscarriage.

Causes

Repeated miscarriages can happen because of any of the following:

  • Chromosonal abnormalities
  • Hormone imbalance
  • Physical Illness
  • Polycystic ovarian syndrome
  • Immune problems
  • Antiphospholipid antibodies
  • Problems in the uterus
  • Life style of the woman

Let's discuss these in detail.
