Pregnant individuals often have questions and anxieties about their baby’s well-being. Ultrasounds are a common medical procedure, but can raise concerns about their perceived physical intensity. Understanding ultrasounds and the actual causes of miscarriage can provide clarity and reassurance.
How Ultrasounds Work Safely
Ultrasound technology employs high-frequency sound waves to generate images of the fetus and surrounding structures within the womb. A transducer emits these sound waves, which bounce back as echoes from tissues and fluids. A computer processes these echoes, converting them into visual images. Unlike X-rays, ultrasounds do not use ionizing radiation, contributing to their established safety for both the pregnant individual and the developing baby. Diagnostic ultrasound has been a standard and widely used component of prenatal care for decades, with extensive research supporting its safety when performed by trained professionals.
Understanding Miscarriage Causes
Miscarriage, defined as the loss of a pregnancy before 20 weeks of gestation, is common, with most instances happening during the first trimester. The primary reason for early miscarriages is chromosomal abnormalities in the developing embryo. These occur when the fertilized egg has an incorrect number of chromosomes or structural issues, preventing proper development. This genetic imbalance typically happens by chance and is not related to external factors or the pregnant individual’s actions.
While chromosomal issues account for about 50% of first-trimester miscarriages, other factors can also contribute. These include maternal health conditions such as uncontrolled diabetes, thyroid disorders, or uterine abnormalities. Infections, hormonal imbalances, and issues with the implantation of the fertilized egg can also play a role. Routine activities like exercise, sexual activity, or moderate stress have not been scientifically linked to causing miscarriage.
Addressing Concerns About Perceived Rough Ultrasounds
During an ultrasound, sonographers may apply firm pressure with the transducer on the abdomen to obtain clear images. This pressure ensures optimal contact and sound wave penetration. Transvaginal ultrasounds, often used in early pregnancy, involve the gentle insertion of a lubricated probe, which can cause a sensation of pressure or mild discomfort.
This sensation does not harm the fetus. The developing baby is well-protected within the uterus, cushioned by amniotic fluid, which acts as a shock absorber. The uterine walls are strong muscles that further shield the fetus from external forces. Sonographers are trained healthcare professionals who perform these procedures safely, ensuring any discomfort experienced is typically superficial and does not indicate internal injury.
When to Seek Medical Advice
While ultrasounds are safe and generally do not cause miscarriage, pregnant individuals should be aware of symptoms that warrant immediate medical attention. If you experience vaginal bleeding, especially if it progresses from light to heavy, or is accompanied by abdominal pain or cramping, contact your healthcare provider immediately. Other symptoms requiring prompt evaluation include a sudden gush of fluid from the vagina, severe back pain, or a significant decrease in fetal movement (if applicable to your gestational age). If unsure, contacting your doctor or midwife with any concerns about your pregnancy is advisable. They are the best resource for personalized guidance and reassurance regarding your health and your baby’s well-being.
