Leg cramps during pregnancy: Why they occur and how to prevent them

A sudden, sharp, and painful spasm of the calf muscle that wakes you up in the middle of the night — this is a cramp, one of the most unpleasant "surprises" of the second and third trimesters. Although the exact causes of this phenomenon are not fully understood, several theories explain its occurrence.

Possible causes of night cramps

• Muscle fatigue. Your legs carry extra weight throughout the day, leading to accumulated fatigue in the muscles.
• Circulatory disturbances. The enlarged uterus presses on the veins, making blood return from the legs more difficult. This can lead to a buildup of lactic acid in the muscles, provoking spasms.
• Micronutrient deficiency. An imbalance of calcium, magnesium, and potassium in the body is considered one of the main causes of cramps. The need for these minerals increases significantly during pregnancy.
• Dehydration. Insufficient fluid intake can also contribute to muscle spasms.

Although cramps are very painful, they are usually not dangerous. However, if they occur very frequently, or the leg pain does not subside, it is advisable to discuss this with a doctor to rule out more serious problems such as thrombosis. For prevention, it is important to follow a balanced diet and perform gentle stretching exercises.
