What Causes Leg Cramps at Night?

"I wonder why I get leg cramps when I sleep." And sometimes there is no clear answer to the question, but there are many reasons for increased chances of getting leg cramps during the night.

1. Muscle Fatigue:
If you have overused your muscles while exercising or been standing up for a long enough amount of time, then you may get cramps at night.

2. Dehydration:
If you don't drink enough water, you can have a decrease in normal muscle function, which causes an increased likelihood of cramping.

3. Electrolyte Imbalance:
If you are lacking in potassium or magnesium or calcium, these minerals affect how your muscles contract and may contribute to having muscle contractions when you are sleeping.

4. Poor Blood Circulation:
Reduced blood flow to your legs can cause your muscles to be in pain and also produce muscle cramps.

5. Sitting or Standing for Long Periods of Time:
Staying in one position for a long period of time puts stress on your muscles.

6. Pregnancy:
Women who are pregnant are more likely to experience leg cramps during the second and third trimesters of their pregnancies.

7. Aging:
With aging, we naturally lose muscle, and we also become less flexible, thus increasing the chances of getting leg cramps at night as we age.

8. Medical Conditions:
Leg cramps during the night may be related to having one or more of the following medical conditions: diabetes; kidney disease; liver disease; peripheral artery disease; thyroid disorders; or nerve disorders.

10. Some Medications:
Certain medications may contribute towards having leg cramps during the night when you are sleeping. Some examples of some medications are diuretics; statins (cholesterol lowering); blood pressure medications; and some medications used for asthma.
