Determining a single "biggest" risk for miscarriage is challenging because multiple factors can significantly increase the likelihood of pregnancy loss. However, advanced maternal age is often cited as a major contributing factor. Other notable risks include lifestyle factors and underlying health conditions.
Key Risk Factors for Miscarriage
Several factors contribute to the risk of miscarriage, as outlined in the provided references:
- Being older: Advanced maternal age is a significant risk factor.
- Smoking: Smoking during pregnancy increases the risk of miscarriage.
- Using Certain Drugs: The use of certain drugs, particularly stimulants like cocaine or high amounts of caffeine, can elevate the risk.
- Uncontrolled Chronic Conditions: Uncontrolled chronic conditions such as diabetes or high blood pressure can contribute to miscarriage.
Understanding the Combined Risks
While age is a significant factor, it's important to consider these risks in combination. For example, an older woman with uncontrolled diabetes who smokes would face a considerably higher risk than a younger, healthy non-smoker. Addressing modifiable risk factors can potentially improve pregnancy outcomes.
