Routine ultrasound testing not proven safe for pregnant women

Clicks:Updated:2016-09-22 09:09:14

(NaturalNews) It is common for a pregnant woman to undergo several routine ultrasounds during her 40-week pregnancy. What many don't know, and despite what popular medical and government websites state, ultrasound scans have never been proven safe for pregnant women or babies and aren't recommended for routine use and non-high risk pregnancies.

An ultrasound is a diagnostic scan that emits ultra-high-frequency sound waves at tissues or bones. As the echo waves return to the machine, a picture is created. In the 1970s it was thought that ultrasounds were safe for pregnant women because of the very low scanning intensities; however, since 1993 the FDA has allowed high-output machines to scan babies at eight times the tolerable level without conducting any epidemiological studies. In addition, each scan heats surrounding tissues and bones up to six degrees higher than the maximum determined level of safety and can cause cavitation, where gas pockets in tissues and body fluid collapse. This can lead to a disruption in cell function and permeability, bleeding, and can have adverse effects on early fetal development.



Ultrasound studies done on animals have shown cell abnormalities to several generations, brain hemorrhages, lung damage, slow locomotor and learning abilities that worsened with longer exposure, and neuronal migration abnormalities consistent with autism and dyslexia in humans. Mice exposed to 600 minutes of ultrasound survived no longer than ten days.

Despite convincing evidence in animals that ultrasounds are dangerous, few studies have been conducted on humans, most of which are from other countries who limit ultrasound use. These studies have shown the following adverse effects including preterm labor, miscarriage, low birth weight, poorer birth condition, perinatal death, dyslexia, inner ear damage, and delayed speech development. An Australian randomized Doppler study involving high-risk mothers found more fetal distress in labor and lower APGAR scores at birth. Another Australian study showed that babies given five or more ultrasounds during pregnancy were 30 percent more likely to develop intrauterine growth retardation consistent with the findings in animal studies.
