High glucose tolerance with leg swelling and calcium deficiency: What is the cause?

High glucose tolerance, calcium deficiency, and leg swelling may result from the combined effects of multiple factors. 1. High glucose tolerance may indicate that the pregnant woman is at risk for gestational diabetes, which is caused by insufficient insulin secretion or reduced response of the body to insulin. This can subsequently affect calcium metabolism and absorption, exacerbating the calcium deficiency. 2. Calcium deficiency is another significant cause. Calcium is one of the essential minerals in the body and is vital for maintaining bone health, nerve conduction, muscle contraction, and other physiological functions. During pregnancy, the demand for calcium increases. If calcium intake is inadequate or absorption is impaired, symptoms of calcium deficiency such as leg cramps, low back pain, and muscle aches may occur. In severe cases, it may even lead to osteoporosis. 3. Leg swelling may be caused by edema during pregnancy, which is related to hormonal changes in the body and increased uterine size that compresses venous return. Additionally, calcium deficiency and high glucose tolerance may indirectly affect fluid balance and blood circulation, thereby worsening the symptom of leg swelling. Pregnant women are advised to seek timely medical evaluation and receive targeted treatment.
