Introduction

Miscarriage is a heartbreaking and often misunderstood part of many pregnancies. It is defined as the loss of a pregnancy before the 20th week, and while it is a common occurrence, it is something that many people feel uncomfortable discussing. According to the American Pregnancy Association, up to 20% of known pregnancies end in miscarriage. However, the emotional and physical impact is often profound for those affected.

One myth that frequently circulates is that stress can directly cause a miscarriage. Many expectant mothers worry that their emotional struggles could harm their pregnancy, especially when under significant life stress. But is this belief grounded in scientific evidence, or is it just a misconception? This article will explore the facts about stress, its effect on pregnancy, and clarify some of the common myths surrounding stress and miscarriage.

What is Stress? Understanding Its Impact on the Body

Stress is the body’s natural reaction to any challenge or demand, triggering the "fight or flight" response. Stress can come from various sources — physical, emotional, or psychological. During pregnancy, the body goes through significant hormonal changes, and these changes can make stress more difficult to manage.

When we experience stress, the body releases hormones such as cortisol and adrenaline. These hormones can increase heart rate, elevate blood pressure, and, over time, affect the immune system. While stress in small amounts is a normal part of life, excessive and chronic stress can contribute to health problems, both for the mother and her baby.

However, the effects of stress during pregnancy are complex. Research suggests that although high levels of stress might affect pregnancy health, it does not directly lead to miscarriage in the majority of cases. Instead, stress can influence other pregnancy complications, such as preterm birth or high blood pressure, which can affect the health of both mother and baby.
