Doctor's answer (1)
Dr. Zhang Lu
Leg cramps during pregnancy are quite common and may primarily be caused by the following factors:
1. Calcium deficiency: Imbalances in electrolytes such as calcium, magnesium, or potassium in the body can lead to muscle spasms. As the fetus develops, the demand for these minerals increases. Insufficient intake may result in leg cramps.
2. Fatigue: In the second half of pregnancy, the increasing body weight places extra strain on the legs. The leg muscles often remain in a fatigued state, leading to the accumulation of acidic metabolic byproducts, which may trigger leg cramps.
3. Dietary and nutritional imbalances: Long-term picky eating habits or insufficient food intake can lead to inadequate calcium consumption. Alternatively, excessive meat consumption in one meal may interfere with carbohydrate metabolism, causing an accumulation of acidic metabolic byproducts and resulting in electrolyte disturbances that can induce cramps.
4. Cold temperatures and improper sleeping positions: Low indoor temperatures at night during winter or improper sleeping postures, such as prolonged pressure on the calves while sleeping on one side, can also cause leg muscle spasms.
If cramps occur frequently, it is advisable to consult a doctor promptly to rule out other potential health issues.
