What smart scales can do for pregnant women

During pregnancy, the expectant mother needs to monitor her weight; not only her well-being, but also the condition of the fetus largely depends on this. Weighing should be done regularly, and not just during a visit to the antenatal clinic, since too rapid weight gain may be a consequence of swelling inside the body. Scales for pregnant women should not only record weight as accurately as possible, but also be absolutely harmless. What measuring instruments are best to use during this period?

Scales for pregnant women. Which ones to choose?

To measure weight at home, floor scales are usually used, of which there are two types.

Mechanical

They are the simplest and most accessible. Measuring actions are carried out due to a spring mechanism installed inside. The principle of operation of mechanical scales is quite simple: under the influence of the gravity of the body, the spring stretches and forces the needle to move along the scale. The value from one division to another usually corresponds to 1 kg, less often 0.5. The advantages of such measuring instruments include low cost, ease of use, calculation accuracy, and durability. They do not contain batteries, so there is no need to change anything.

ADVICE! Press the scale with your foot before use. The arrow should be at the zero mark.When weighing, do not make sudden movements, stand straight and calm.

Electronic

The accuracy of such devices is much higher than that of mechanical analogues. In addition, they may have other functions, which include:

• luminous display with backlit numbers;
• computer analysis of growth and body parameters;
• moisture meter

Among electronic scales, several subgroups can be distinguished:

• Simple, having mechanical internals and an information digital display.
• Models with two different operating principles.
• New generation of devices with four sensors.

The first ones have a built-in disk. Their principle differs little from mechanical analogues, only the measurement results are displayed on the display.

For the second subgroup, the principle of an electric capacitor is used, when two metal plates are located one above the other. Under the weight of the body, the gap between them changes and is transmitted to the microprocessor. The result is an electronic signal on a digital display.

The use of a stress sensor has revolutionized weighing technology. When exposed to the surface of the device, a wire is drawn in, through which an electric current is passed, which leads to a change in the electrical signal. The microprocessor converts it into a numerical value and displays it on the display.

REFERENCE! The operating principle of the new generation models is based on the operation of 4 sensors interconnected. They record the impact pressure on the scales and display the results via a microprocessor on the display.

What pregnancy scales can do

Modern devices can act as a home nutritionist who gives practical recommendations taking into account body mass index and physical activity, determines the difference between weighings, and provides graphical results. They turn on and off automatically, so pregnant women don't have to bend over and do these steps manually.

Expectant mothers should not analyze the amount of water in the body, the ratio of fat and muscle mass. During pregnancy, these results will most often be given with large errors. In addition, scales with such functions transmit electrical impulses through the feet, which can pose a danger to the baby’s health. The instructions for the device usually indicate contraindications.

How much are

The cost of weighing scales depends on the material from which they are made and the number of additional functions. The body can be metal, wood, glass or plastic. Weighing devices have load limits and different power sources, which also affects the price.

Smart plastic scales powered by batteries cost from 3.7 thousand rubles.

The range of prices for devices with individual recommendations that measure twelve parameters of your body varies from 2.8 thousand rubles (mini version) to 6.5.

The most expensive models range from 15.5 to 18.3 thousand rubles. not only perform a detailed analysis of your body, but also monitor the state of the cardiovascular system.

The choice of scales designed to monitor changes in the weight of the expectant mother is huge. Therefore, it is best to immediately decide what is especially important and choose the model that will be convenient to use.
