Is it normal for the femur to be small for two weeks, and what to do if the fetal femur is small for

Pregnant mothers believe that they are no strangers to prenatal check-ups and B-ultrasound examinations, and some mothers will be told by the examining doctor that the fetal femur is two weeks smaller, and the mothers who are told will inevitably be worried that the baby in the womb is malnourished or has abnormal development. So, what should I do if the fetal femur is two weeks smaller?

1. In fact, it is very common to check that the fetal femur is one to two weeks smaller, and sometimes the fetus is actually not small, but careless or confused mothers have made the wrong date of pregnancy, or the calculation method is wrong. Please understand that the date of menstrual leave is not the same as the date of pregnancy, and the date of pregnancy is generally half a month later than the date of leave.

2. If the date of pregnancy of the pregnant woman is accurate, it is also necessary to consider the possibility of stunted fetal growth, through the examination of a regular hospital, to determine whether the oxygen in the uterus is insufficient, if the lack of oxygen is serious, the situation is urgent, and directly endangers the child's life, then the doctor will generally take decisive measures, and even terminate the pregnancy is possible.

3. Pregnant women have a special physique, they should pay special attention to their living environment and the food they are in, and they should stay away from things that are harmful to their own and the health of the baby in the belly.

According to the examination results, the biparietal diameter was larger for one week and the femoral length was smaller for two weeks.

In the ultrasound data, the ultrasound data related to leg length are femoral length (fetal thigh length) and tibial length (calf length), and the normal value is 2-3 cm different from the double parietal diameter of the corresponding month. Generally speaking, it is normal for this data to be biased for about 2 weeks.

B-ultrasound measures the various diameter values of the fetus, which is not 100% correct and will be affected by some subjective factors, such as the clarity of the B-ultrasound display, the proficiency of the B-ultrasound doctor, etc. Therefore, a B-ultrasound data cannot determine that the baby has short legs or developmental problems.

Excluding the measurement factors, the current reference value of fetal growth and development given by B ultrasound is only the average value, if the difference between the measurement data and the average value is very small, it can also be regarded as normal, and it is not a problem with the baby's development.

Other factors can also affect the judgment of the ultrasound results, such as the time of implantation of the fertilized egg. In addition, genetic factors should also be considered, if one of the parents is not very long legs, it is normal for the baby to have slightly shorter legs. So don't worry too much about pregnant mothers.

In short, if the baby's legs are short due to some pathological reasons, there must be other data or test manifestations, and the doctor will make a comprehensive diagnosis.

If the fetus is found to be small for two weeks through ultrasound, it is necessary to find out the cause of the small size. There are two main factors.

1. In most cases, it may be due to an error in the calculation of the gestational week. Because the size of the baby is calculated based on the last menstrual period. This estimation method is not completely accurate, and there will be a certain deviation for unstable menstrual cycles, and this deviation is often 1 to 2 weeks of time error.

If this is the case, then it is normal, there is no need to worry too much and there is no need for special handling.

Second, it may also be caused by fetal malformation or fetal growth retardation, which needs to be paid attention to at this time. If growth is retarded due to poor nutrition, pregnant women need to increase nutrition to provide more nutrients for the fetus to grow and develop. If it is caused by a fetal malformation, it is recommended to terminate the pregnancy as soon as possible.

Fetal head is larger for two weeks:

1. This situation should be seen in combination with other specific inspection results.

2. If the fetus has a large simple head, that is, the double parietal diameter data is large, it may be due to genetic factors, as long as everything is normal in the prenatal examination, there is no need to worry.

3. If there is no indication that there is fluid accumulation in the head of the fetus, it should not be a problem, not all fetuses have the same body proportions, and it is possible that some fetuses have slightly larger heads. As long as the ultrasound does not suggest that the fetus itself is significantly abnormal, there should be no problem.

Dietary precautions in the third trimester:

In the third trimester, expectant mothers enter the final sprint stage, and the storage of nutrients is particularly important for expectant mothers. A safe, healthy and reasonable diet is a necessary prerequisite for the healthy birth of a fetus. Combined with the nutritional characteristics of the third trimester, the diet of the second trimester should be adjusted accordingly.

1. Diversified dietary requirements: In the late stage of pregnancy, expectant mothers not only need to supplement calories, but also pay attention to the supplement of nutrients such as high-quality protein, iron, calcium and vitamins, and can adopt a diet of eating less and more often, which can increase to more than 5 meals a day. Do not take a large amount of supplements to avoid excessive obesity and macrosomia (the weight gain of expectant mothers during pregnancy should not exceed 15 kg).

2. Supplement sufficient calcium and iron to help the fetus's teeth and bones calcify well and prevent anemia of expectant mothers, you can eat more kelp, seaweed, dried shrimp, sesame, animal liver, eggs, fish, etc.

3. Increase the intake of plant-based proteins, such as beans and soy products.

4. Reduce the intake of foods with high sugar content, such as fruits, sugar, honey, etc., so as not to overgrow the fetus and affect the smooth delivery.

5. Eat more foods with high nutritional value and small size, such as animal foods; Eat less foods with low nutritional value and large volumes, such as potatoes, sweet potatoes, etc.
