Why Miscarriages Occur In 1st Trimester

A miscarriage happens when the embryo or foetus is spontaneously expulsed from the uterus but can’t survive in the outside world. The majority occur around the 12th week of gestation.

Miscarriages can be caused by many factors, ranging from genetic defects in the growing baby to immune reactions by the mother’s body. However, they are not caused by falls, sex or work stress.

Here are some factors to watch out for that may increase the likelihood of it occurring:

Age. Older mums are more likely to conceive a baby with a chromosomal abnormality and to miscarry as a result.

Vitamin levels. Researchers have found that deficiencies in vitamin D and vitamin B can increase a woman’s risk of miscarrying. (Recommended: Take a prenatal vitamin and get your vitamin levels tested).

Being overweight or underweight. Obese women (those with a BMI of 30 or higher) have a higher risk of miscarrying. Likewise, women with a BMI under 18.

Smoking. Smokers, past and present, have an increased miscarriage risk compared with non-smokers.

Caffeine Consumption. Drinking more than 200mg of caffeine a day. (1 mug of coffee contains around 100mg of caffeine). (Note: Caffeine is also found in fizzy drinks, energy drinks and chocolate.)

Certain STDs. Sexually transmitted diseases, including syphilis and some forms of viral hepatitis can make a woman more prone to having a miscarriage.

Medications. Some over-the-counter medications, including common painkillers, have been linked to miscarriages. (Recommended: Always check with your doctor before taking any medicine.)

Environmental toxins. Exposure to lead, mercury, organic solvents and ionizing radiation.
