What causes leg cramps during pregnancy ?


It is not uncommon to experience leg cramps and restless legs during pregnancy, particularly in the 3rd trimester. Many pregnant women experience some form of muscle spasms in their legs, with cramping being more frequent whilst sleeping.


Leg cramps during pregnancy may be caused by the following :

  • Additional weight gain of pregnancy
  • Changes in your circulation with pressure from the growing baby on your nerves and blood vessels
  • Limited movement / if you are in active during pregnancy.
  • Postural alignment changes
  • Mineral /Electrolyte deficiency – particularly magnesium and potassium.


How do you treat and avoid leg cramps during pregnancy ?

  • Exercise regularly including safe and gentle stretches.
  • Improve your mobility and posture – correct alignment of your body can help take pressure of your legs and hips.
  • Rest with your legs elevated
  • Wear supportive compression stockings or leggings.
  • Have a regular massage – of legs / calves.
  • Potassium and magnesium are both considered key minerals that your body needs. These minerals are known as electrolytes and influence the volume of water in your body and your pH levels. Sweating and vomiting (hello morning sickness !!) causes your body to lose these valuable electrolytes, which may negatively affect your body and lead to painful muscle cramps. A natural way to improve these levels are to eat bananas – high in potassium and drink unsweetened coconut water naturally full of electrolytes. My nutrition guide should help.

Please contact your medical practitioner if leg cramps are severe or persistent.
