Physiological Effects of Twins in Two Fetal Test Tube Infants on Maternal Health
The development of IVF technology has enabled more and more couples to realize their dream of having a second child. However, the twins of two test tube babies may have some physiological effects on the maternal health. This article will elaborate on the nutritional requirements, pregnancy complications, weight control and genital changes.

1、 Nutritional requirements
The emergence of two test tube twins means that the mother needs to provide sufficient nutrition to support the growth and development of the two fetuses. This means that the mother needs to increase daily calorie intake to meet the needs of fetal growth. In addition, twin pregnancy also needs more protein, vitamins and minerals. If the mother can not meet the nutritional needs of twins, it may lead to complications during pregnancy.
In addition, pregnant women need to pay special attention to weight control during the second IVF twins. Obesity or obesity may increase the risk of prenatal complications. Therefore, compared with singleton pregnancy, the nutritional requirements of twins of two test tube babies are greater, and mothers need to make scientific and reasonable diet plans.
2、 Pregnancy complications
Compared with singleton pregnancy, twin pregnancy has a higher risk of complications. For example, twin pregnancy may lead to an increase in the incidence of pregnancy induced hypertension and diabetes. In addition, twin pregnancy also has a higher risk of complications such as uterine fibroids, placental abruption and placenta previa.
Therefore, during the period of two test tube twins, pregnant women need to pay more attention to their own physical conditions and conduct regular prenatal examinations. Doctors will make corresponding nursing plans according to the weight and physical condition of pregnant women to reduce the risk of complications.
3、 Weight control
During the period of two test tube twins, pregnant women need to focus on weight control. Due to the higher nutritional requirements of twin pregnancy, pregnant women are prone to obesity, increasing the risk of complications during pregnancy. Obesity may lead to hypertension during pregnancy, diabetes, fatty liver during pregnancy and other problems.
In order to control weight, pregnant women can reduce calorie intake by limiting the intake of foods with high sugar, fat and salt. In addition, moderate exercise is also an important way to maintain a healthy weight. However, it should be noted that pregnant women should follow the doctor's advice when carrying out weight control, and should not blindly reduce calorie intake or excessive exercise to avoid adverse effects on the mother and fetus.
4、 Changes in reproductive organs
Twin pregnancy will make the uterus of a pregnant woman larger than that of a singleton pregnancy, which is to provide sufficient space for growth. The uterus of a pregnant woman may become more round and higher, and in the late pregnancy, the uterus may compress other organs of the mother, such as the bladder and stomach, causing frequent urination and indigestion.
In addition, the pelvis of pregnant women will also experience certain changes. The pelvis may become wider due to greater stress on twin pregnancies. These changes in reproductive organs are normal physiological phenomena, but sometimes may cause some discomfort to the mother.
To sum up, the twins of two test tube babies have certain physiological effects on maternal health. Pregnant women need to pay more attention to their own nutritional needs, strengthen weight control, and face the risk of complications during pregnancy. In addition, pregnant women also need to adapt to changes in reproductive organs. The guidance of doctors and regular prenatal examination are important measures to ensure the health of pregnant women and fetuses.
