Introduction

Anatomically, the fundus of the uterus refers to the uppermost portion of the uterine body, located near the top of the pelvic cavity. When the placenta attaches to the fundus, it mainly extends upward within the uterine body. The visibility of the pregnancy bump is more closely related to factors such as the placenta's attachment site on the anterior or posterior uterine wall, fetal size, and maternal abdominal fat thickness. Regular prenatal checkups should be conducted to monitor fetal development.

In general, when the placenta is attached to the fundus of the uterus, the abdomen may not show prominently, which is related to the anatomical position of the uterus and the physiological characteristics of the placental attachment area. The specific analysis is as follows:

Anatomically, the fundus is the uppermost part of the uterine body, located near the top of the pelvic cavity. When the placenta is attached to the fundus, it mainly extends upward within the uterine cavity. The visibility of the abdominal bulge is more closely associated with factors such as placental position on the anterior or posterior wall of the uterus, fetal size, and thickness of the abdominal fat in the pregnant woman. If the placenta is attached to the anterior wall of the uterus, fetal growth may exert direct pressure forward on the abdominal wall, resulting in earlier visibility of the pregnancy. In contrast, the fundal position is relatively higher and farther away from the superficial layer of the abdominal wall. Placental growth at the fundus tends to expand more into the upper space of the uterus, exerting less direct pressure on the front of the abdominal wall, so the visual appearance of abdominal protrusion may be relatively delayed.

In addition, whether the abdomen shows prominently also depends on the woman's body type. In tall women or those with tight abdominal muscles, the abdominal bulge might not be obvious even if the placenta is located at the fundus. Conversely, women with shorter stature or relaxed abdominal walls may show more obvious abdominal protrusion, although this is not directly related to placental position. It is important to note that placental positions, such as fundal, anterior, or posterior wall attachment, are all normal physiological conditions. As long as the placenta does not cover the internal cervical os, it generally does not affect the progress of pregnancy.

Regular prenatal checkups should be conducted to monitor fetal development. Maintaining a balanced diet is also important to support healthy fetal growth.

What does it mean when there is too little amniotic fluid at seven months of pregnancy, and what should be done?

Low amniotic fluid at seven months of pregnancy may be caused by insufficient water intake, mild placental insufficiency, fetal urinary system developmental abnormalities, gestational hypertension, or gestational diabetes. It can usually be managed through general measures, medication, or other treatments. If any abnormalities occur, prompt medical attention is recommended. In daily life, pregnant women should ensure adequate hydration, maintain a balanced diet, and avoid fatigue.

What can I eat in the late stages of pregnancy to relieve abdominal pain?

In general, the appropriate diet to relieve abdominal pain in late pregnancy depends on the specific underlying cause. Common causes include false labor contractions (Braxton Hicks contractions), fetal engagement (lightening), acute gastroenteritis, threatened uterine rupture, and placental abruption. If discomfort occurs, it is recommended to promptly seek treatment at a正规 hospital. A detailed analysis is as follows:

How to manage placental insufficiency

In general, placental insufficiency may be caused by factors such as post-term pregnancy, maternal malnutrition, gestational hypertension, gestational diabetes mellitus, fetal growth restriction, and others. It is recommended to seek timely medical attention, identify the underlying cause, and manage the condition under a doctor's guidance through general treatment, medication, or delivery interventions. Daily care should ensure adequate rest for the pregnant woman and avoid excessive fatigue.

Can placenta be eaten, and what are its functions and benefits?

Under normal circumstances, the placenta that has been professionally processed is edible. Its functions and effects generally include supplementing proteins, providing trace elements, improving immune function, and assisting in regulating endocrine function; however, individual responses may vary. When consuming placenta, it is important to choose a healthy placenta processed by a legitimate medical institution, ensuring it has been thoroughly cleaned, disinfected, dried, and made into powder or capsule form.
