Understanding why your feet cramp.

If you’ve ever suffered from sudden, severe pain in your feet, particularly during nighttime or vigorous exercise, it’s likely that you have experienced a foot cramp.

Foot cramps are caused by involuntary spasms of the muscles and can be incredibly painful and unpleasant – even if they are relatively short-lived. While the exact cause remains unknown in some cases, there can often be an underlying medical condition to blame, and understanding these causes is the first step toward prevention. In this blog post, we’ll look at some potential reasons why you might suffer from foot cramps, as well as give advice on how best to manage them should they occur again.

Why Do We Get Foot Cramps?

Foot cramps, a sudden and involuntary contraction of the muscles, can be quite an unwelcome and painful experience. There are several factors that contribute to this distressing condition, some of which are rooted in our daily habits and health status.


Dehydration and electrolyte imbalances are primarily caused by a lack of proper hydration. When we don’t take in enough fluids, our bodies may struggle to regulate the electrolytes (minerals such as sodium and potassium). This can lead to an imbalance that affects muscles throughout the body, including those in the feet.

Lack of Vitamins & Minerals

Insufficient intake of key minerals like potassium, magnesium, and calcium, tends to be a significant contributor, as these minerals play a crucial role in ensuring normal muscle function.


Potassium is a mineral that helps to regulate the muscles, while magnesium plays an important role in nerve and muscle function.


Calcium is also known to be essential for muscle contractions – hence why cheese and milk are good sources of calcium!

Vitamin B6

Vitamin B6 is important in helping the body to make energy, and has also been found to help prevent cramps.

Vitamin D

Vitamin D is needed for the absorption of calcium and phosphorus, so if you’re deficient in this vitamin, you may be more prone to cramps.

Vitamin E

Vitamin E assists with the growth and repair of muscle tissue, and so a deficiency may lead to cramps.

Health Issues

Certain medical conditions, such as diabetes and kidney disease, can also lead to cramps. Kidney failure can cause an electrolyte imbalance which in turn leads to painful cramps, while those with diabetes might suffer from different types of neuropathy (nerve damage) that cause muscle spasms.


Medication can also be a factor. Many medications, such as statins, calcium channel blockers, and beta-blockers can cause cramps or reduce the body’s electrolyte levels which can lead to muscle spasms. Additionally, those who take diuretics (water pills) may experience cramps due to dehydration.

Reduced Circulation

Reduced circulation, especially when it affects the feet, can lead to cramping. The lack of oxygen-rich blood and nutrients being supplied to the area can cause muscle spasms.

Overly Vigorous Exercise

Vigorous exercise puts a great strain on the muscles and may cause them to spasm or cramp as a result.


Fatigue can cause the muscles to become weak and tired, making them more prone to cramping.


Pregnant women may experience cramps more often due to the physical strain on their bodies and the additional weight they are carrying.

Footwear That Doesn’t Fit Right

Ill-fitting shoes can affect the normal positioning and movement of the foot, leading to cramps.

How to Stop Foot Cramps?

The best way to manage cramps is to be proactive. Make sure you’re adequately hydrated, eat a balanced diet with plenty of minerals and vitamins, exercise regularly but not excessively, and take steps to improve circulation in your feet (such as wearing supportive shoes).

Increase Water Intake

Drink plenty of water throughout the day, as dehydration is a major cause of cramping. Consume between 3-4 liters of fluids daily, or around 6 to 8 cups for optimal hydration.


Potassium, magnesium, calcium and vitamin B6 can all help to prevent muscle cramps. Taking supplements is an easy way to ensure that you’re getting the right balance of minerals and vitamins in your diet.

Stretch & Massage

Stretching before exercise helps to warm up the muscles and reduce the risk of them cramping. After exercise, gently massage the affected area to help reduce tension and relax the muscles.

Heat or Cold Therapy

Applying either heat or cold to the affected area can help reduce pain and ease muscle spasms. However, make sure to test both methods before applying them on your feet as some people find that one works better than the other.


Wearing properly fitted shoes can help to reduce the risk of cramping. Look for shoes that are supportive and comfortable, as these will help to protect your feet from injury and strain.

Elevate Your Feet

If you’re experiencing cramps in your feet, try elevating them above your head while lying down. This can help to reduce tension and improve circulation in the area.

Keep Moving

Try to keep your feet moving whenever possible. Sitting or standing for too long increases your risk of cramping, so take regular breaks and move around frequently.

Can Leg Cramps Be A Sign Of Something Serious?

Question Mark white (1)

In most cases, leg cramps are not a sign of something serious and can be managed with simple lifestyle changes. However, if the cramps persist or become more frequent over time, it’s important to speak to your doctor in order to rule out any underlying medical conditions. Severe cramping that is accompanied by other symptoms such as numbness, tingling, or weakness can be a sign of nerve damage or an underlying medical condition and should be checked out by a doctor. Additionally, if the cramping occurs at night while sleeping, this may indicate an electrolyte imbalance which should also be evaluated by a healthcare professional.
