Muscle spasms can be caused by various factors, from exhaustion and stress to certain medical conditions. While occasional muscle spasms are normal, they can sometimes indicate an underlying health issue. For instance, muscle spasms may be a symptom of multiple sclerosis, amyotrophic lateral sclerosis, or fibromyalgia. In addition, nutrient deficiencies, such as a lack of calcium, magnesium, or vitamin D, can lead to muscle spasms. Other potential causes include dehydration, injury, and certain medications. If muscle spasms are frequent or cause pain, it is recommended to consult a doctor for further assessment and treatment.

What You'll Learn
Exhaustion and stress can cause muscle spasms
Exhaustion and stress can indeed cause muscle spasms. Occasional muscle spasms are a normal part of life, but they can sometimes be indicative of an underlying issue. In many cases, they are nothing to be concerned about, but regular spasms or those causing pain may warrant a check-up with a doctor.
Causes of Muscle Spasms
Muscle spasms can be caused by a variety of factors, including exhaustion, stress, and certain medical conditions. They often happen after exercise, when muscles are tired and cramp up. This can be due to a lack of strength training, which can lead to muscles getting too tired. Dehydration, heavy sweating, and losing body fluids when sick can also cause muscle spasms.
Nutritional Factors
Nutritional deficiencies can also contribute to muscle spasms. For example, a lack of calcium, magnesium, potassium, or vitamin D can lead to spasms. Calcium is essential for proper muscle function, and magnesium helps transport calcium across cell membranes. Potassium and magnesium deficiencies can cause muscle cramps and spasms. Certain medications can also deplete these minerals.
Neurological Factors
In some cases, muscle spasms may be related to neurological conditions or nerve issues. For instance, multiple sclerosis, amyotrophic lateral sclerosis (ALS), and Tourette's syndrome can cause muscle twitches and spasms. Additionally, nerve damage or conditions affecting the nerves, such as neuropathy, can lead to spasms.
Treatment and Prevention
While most muscle spasms are harmless and temporary, it is important to seek medical advice if they persist or are accompanied by other symptoms. Doctors can work with individuals to develop treatment plans and manage symptoms. Relaxation techniques like massage or meditation can help relieve tension and pain in muscles caused by stress. Strength training and proper hydration can also help prevent muscle spasms.

Mineral deficiencies and dehydration
Dehydration can cause muscle spasms. Dehydration robs your muscles of the fluids they need to function properly, and the ability of nerves to signal muscles is compromised. This can result in miscommunication between nerves and muscles, causing cramps. Water intake after dehydration makes muscles more susceptible to cramping, but this can be reversed by consuming electrolytes. Oral rehydration solutions (ORS) or sports drinks can help maintain the proper electrolyte balance.
Mineral deficiencies can also cause muscle spasms. Calcium, magnesium, potassium, and phosphorus are some of the minerals that are necessary for proper muscle function. A calcium deficiency may cause muscle twitching or spasms. Magnesium helps to keep nerves and muscles healthy and also aids in transporting calcium across cell membranes. Vitamin D plays a role in muscle health, and a deficiency can cause chronic and nonspecific musculoskeletal pain, chronic pain, and muscle weakness.
Vitamin deficiencies can also be a factor in muscle spasms. Vitamin B 12 supports neurological health, and a deficiency can lead to cramps, spasms, tingling in the hands and feet, dizziness, and fatigue. Vitamin D is necessary for the body to absorb calcium, so a deficiency can indirectly cause muscle spasms.

Neurological conditions
While muscle spasms are usually not serious, they can sometimes indicate an underlying neurological condition. These conditions affect the brain, which helps the muscles move. When involuntary muscle movements result from a neurological issue, it is called dystonia.
Some people are born with neurological conditions that affect the nerves that control their muscles, but it can also happen due to injury, infection, disease, alcoholism, or certain medications. Diabetes is the leading cause of neuropathy, a condition where the nerves send signals that make the muscles move even though the brain or spinal cord isn't telling them to. This can cause muscle twitching, cramps, and stiffness, and the symptoms may continue during sleep or under general anaesthesia.
While exhaustion itself is not a neurological condition, it can be a factor contributing to muscle spasms. Intense physical activity, especially in hot environments, can lead to heat cramps, a type of muscle spasm caused by the body overheating. Heat cramps can turn into heat exhaustion or heatstroke if the person remains in a hot environment and does not replenish lost electrolytes. Therefore, it is important to cool down, stay hydrated, and replace lost electrolytes to prevent heat-related illnesses.

Medication and supplements
While muscle spasms are usually harmless and temporary, requiring little to no treatment, they can sometimes be indicative of an underlying health condition. In such cases, a doctor will work with the patient to develop a treatment plan to manage the symptoms.
If you experience muscle spasms, it is important to consult a doctor to determine the underlying cause and discuss treatment options. Some medications have been known to cause muscle spasms as a side effect. These include:
- Cholesterol-lowering drugs such as statins and fibrates
- Antiarrhythmic medicines used to treat heart rhythm problems
- Corticosteroids, such as prednisone
- Antidepressants
- Epilepsy and psychosis drugs
- Diuretics or water pills
- Labetalol
In some cases, muscle spasms may be caused by a vitamin or mineral deficiency. Common deficiencies that can lead to muscle spasms include:
- Magnesium
- Vitamin D
- Vitamin B12
If you suspect a nutrient deficiency, it is important to speak to a healthcare provider about supplements. They may recommend testing nutrient levels in the blood to determine if levels are within a healthy range before suggesting a course of action.
Some prescription medications that may help prevent muscle spasms include:
- Carisoprodol (Soma®): A muscle relaxant
- Diltiazem (Cartia XT®): A calcium-channel blocker
- Orphenadrine (Norflex®): Treats muscle spasms and relieves pain and stiffness in muscles
- Verapamil: A calcium-channel blocker
- Gabapentin (Neurontin): An anticonvulsant and nerve pain medication
It is important to note that supplements and vitamins may not be effective in preventing or treating muscle spasms in all cases. For example, while magnesium is often recommended for leg cramps, there is conflicting evidence regarding its effectiveness in treating muscle spasms.

Underlying health conditions
While occasional muscle spasms are normal, they can sometimes be indicative of underlying health conditions.
Neuromuscular disorders
Patients with neuromuscular disorders may experience chronic myofascial pain (e.g. fibromyalgia) or contraction-induced pain (e.g. metabolic myopathies). Transcranial magnetic brain stimulation has been used to investigate changes in the central motor pathway during fatiguing muscle activity, shedding light on the mechanisms of fatigue in individuals with chronic fatigue syndrome and multiple sclerosis. However, there is limited research on patients with neuromuscular disorders.
Degenerative neurological conditions
In rare cases, muscle twitching can indicate a degenerative neurological condition such as amyotrophic lateral sclerosis (ALS). ALS causes a gradual decline in nerve cell function, affecting voluntary muscle movements. Over time, individuals with ALS may lose the ability to control their movements.
Multiple sclerosis (MS)
Multiple sclerosis (MS) is a degenerative condition that affects the central nervous system. Muscle twitching in MS is referred to as spasticity.
Bell's palsy, Tourette's syndrome
Eye twitches can sometimes be a sign of brain or nerve disorders like Bell's palsy, multiple sclerosis, or Tourette's syndrome. However, these conditions typically present with additional symptoms.
Vitamin and mineral deficiencies
Vitamin and mineral deficiencies can contribute to muscle spasms. For example, a lack of calcium, magnesium, or vitamin D can impact muscle function and lead to spasms or twitches.
Kidney-related issues
Kidney problems, particularly in individuals with diabetes, high blood pressure, or other kidney-related issues, can lead to muscle cramps and spasms.
Diabetes
Diabetes is the leading cause of neuropathy, a condition where damaged nerve cells alter their communication with each other and the brain. Spasms and twitches can be warning signs of neuropathy, affecting the nerves that control muscles.
Medications
Certain medications can also cause muscle twitches and spasms. For example, some antidepressants, epilepsy drugs, and psychosis drugs may have these side effects. Additionally, water pills or diuretics prescribed for high blood pressure or heart disease can deplete potassium levels and trigger muscle spasms.
