Introduction
In general, lower back pain upon waking during the second trimester of pregnancy may be related to prolonged maintenance of a single sleeping position, pressure from fetal growth, calcium deficiency, glomerulonephritis, or pelvic inflammatory disease, and requires symptomatic treatment. If a pregnant woman maintains the same sleeping posture for an extended period, it may lead to discomfort and pain in the muscles and joints of the lower back, potentially causing the aforementioned symptoms.
Generally, lower back pain upon waking during the second trimester of pregnancy may be related to prolonged maintenance of a single sleeping position, pressure from fetal growth, calcium deficiency, glomerulonephritis, or pelvic inflammatory disease, among other causes. Appropriate treatment based on the underlying cause is necessary. Specific details are as follows:
1. Prolonged maintenance of a single sleeping position
If a pregnant woman maintains the same sleeping posture for an extended period, it may lead to discomfort and pain in the muscles and joints of the lower back, resulting in the aforementioned symptoms. It is recommended that pregnant women change their sleeping positions appropriately, avoid postures that trigger back pain, and gently massage the lower back area. Symptoms usually gradually improve with these measures.
2. Pressure from fetal growth
As pregnancy progresses, the fetus grows larger and the uterus expands and protrudes forward, which may place pressure on the lower back and pelvic region, causing back pain and discomfort—leading to the symptoms described above. Pregnant women are advised to get adequate rest, maintain a light diet, and apply warm compresses using a heated towel to the painful area. These measures typically help alleviate symptoms over time.
3. Calcium deficiency
Pregnant women require additional calcium to support fetal skeletal development. Insufficient calcium intake may result in bone pain and general discomfort, manifesting as the symptoms mentioned. It is recommended that pregnant women take calcium supplements such as calcium lactate chewable tablets or compound calcium carbonate granules under medical guidance.
4. Glomerulonephritis
Glomerulonephritis is a kidney disorder that can cause abnormal kidney function and inflammatory responses, potentially leading to back pain and the symptoms described, especially when physiological changes and increased metabolic demands occur during pregnancy. Due to the special condition of pregnant women, medication is generally not recommended. Instead, a light diet, increased fluid intake, and moderate exercise are advised, which may help improve the condition.
5. Pelvic inflammatory disease (PID)
Pelvic inflammatory disease refers to infection and inflammation of organs within the pelvic cavity, which may cause pain in the lower back and pelvic region. This condition is more likely to occur when a pregnant woman's immune system is relatively weakened, potentially resulting in the symptoms described. Medication is typically not recommended during pregnancy; instead, maintaining good hygiene, including regular cleaning of the external genital area, is advised and may help improve the condition.
Pregnant women experiencing any discomfort should seek timely medical evaluation and receive standardized treatment under the guidance of a healthcare provider. Self-medication should be avoided to prevent potential risks to both maternal and fetal health.
