What are the hazards of B-ultrasound to the human body

With the continuous development of medical methods, many diseases that were difficult to cure in the past can now get a good treatment effect, and the emergence of B-ultrasound has brought us great convenience in treating diseases. However, according to many medical reports in recent years, frequent B-ultrasound is more or less harmful to our human body, and these hazards will cause some complications after years of accumulation. So what are the hazards of B-ultrasound to the human body?

Question 1: Why can we see the fetus through B-ultrasound? How does B-ultrasound work?

B-ultrasound, also known as ultrasonic diagnosis, utilizes a sound with a frequency that is beyond the human hearing range. It can penetrate objects and if it hits an obstacle, it will produce an echo. Different obstacles will produce different echoes. People collect this echo through instruments and display it on a screen, which can be used to understand the internal structure of the object. Using this principle, people use ultrasound to diagnose and treat human diseases.

Doubt 2: I had a B-ultrasound once, and it was very painful for me to hold my urine. Do I need to hold my urine during the entire pregnancy when doing ultrasounds?

No. In the early stages of pregnancy (usually the first three months), the uterus is not large enough and has not protruded from the pelvic cavity, so you need to hold your urine and use a full bladder to help see the uterus, fallopian tubes, ovaries, etc. In the middle and late stages of pregnancy, there is generally no need to hold urine, unless there are special circumstances, such as a low placenta or unexplained vaginal bleeding, in which case a full bladder is needed to clearly see the tissue and blood flow in the lower part of the uterus.

Doubt 3: Every time I do an ultrasound, the doctor will apply something like glue on my stomach. Is this sticky liquid harmful to the skin and the fetus?

The colloid applied before B-ultrasound is called "coupling agent", which can make the probe and skin contact closely and develop better. This coupling agent is water-based, non-irritating to the body, and harmless to the skin and fetus. Pregnant mothers can rest assured and just wipe it off with paper after the examination.

Doubt 4: When doing B-ultrasound, doctors will study the screen carefully for a long time. What can they see through B-ultrasound?

After 5 months of pregnancy, you can use B-ultrasound to see a relatively well-developed fetus, such as the face, facial features, torso, limbs, as well as the umbilical cord and placenta connecting to the mother.

The above paragraphs are some of the answers to the question of the harm of B-ultrasound to the human body that I introduced to you today. Therefore, I hope that patients who often need to undergo physical examinations through B-ultrasound must make a cautious choice for this medical method. Of course, I would also like to point out that when we are checking diseases, we should try not to use B-ultrasound for examination first. It is best for us to choose an experienced doctor to avoid the harm of B-ultrasound to the human body.
