Introduction
In the late stages of pregnancy, feelings of chest tightness and shortness of breath may be caused by physiological factors or pathological factors, such as pneumonia or patent ductus arteriosus. Specifically, during late pregnancy, the uterus gradually enlarges, elevating the diaphragm and reducing thoracic capacity, thereby impairing pulmonary gas exchange and leading to symptoms of chest tightness and shortness of breath.
Feeling chest tightness and shortness of breath during the late stages of pregnancy may be caused by physiological factors, or it could result from pathological conditions such as pneumonia or patent ductus arteriosus. The specific analysis is as follows:
I. Physiological Factors
During the late stages of pregnancy, the uterus gradually enlarges, elevating the diaphragm and reducing thoracic cavity capacity, thereby affecting gas exchange in the lungs and leading to sensations of chest tightness and shortness of breath. This condition is considered normal and generally does not require excessive concern. Pregnant women are advised to rest adequately and avoid overexertion.
II. Pathological Factors
1. Pneumonia
Inhaling large amounts of contaminated air during pregnancy may lead to pneumonia, reducing oxygen levels in the lungs and causing these symptoms. Under a doctor's guidance, pregnant women may take medications such as amoxicillin capsules or cefuroxime axetil tablets to improve their condition.
2. Patent Ductus Arteriosus (PDA)
If a pregnant woman already has patent ductus arteriosus, the condition may worsen during late pregnancy due to decreased immune resistance, resulting in insufficient blood supply to the heart and subsequently causing chest tightness and shortness of breath. It is recommended that the pregnant woman seek timely medical care for oxygen therapy to prevent adverse effects on the pregnancy.
Besides the above, tuberculosis can also cause chest tightness and shortness of breath during late pregnancy. Pregnant women are advised to undergo regular hospital check-ups to closely monitor both their own health and fetal development.
