When your magnesium levels are low, you may experience a variety of symptoms. And not all symptoms of magnesium deficiency are normal.

Read along as we discover the signs and symptoms of low magnesium levels, as well as its causes and treatments.

Low Magnesium Symptoms: What is Magnesium Deficiency?

Magnesium is vital for human health, and yet it’s estimated that up to 80% of Americans are deficient in this important nutrient. It plays a role in over 300 biochemical reactions in the body, including energy production, muscle contractions, and blood sugar control.

Magnesium also helps to keep bones strong and promotes healthy skin and hair. A lack of magnesium can lead to a number of health problems, including fatigue, muscle cramps, anxiety, and migraines.

It helps the body process and use other important vitamins and minerals, such as calcium, phosphorus, and sodium. While magnesium is found in many foods, including dark leafy greens, nuts, seeds, and whole grains, most people do not get enough of this essential nutrient through diet alone.

Most people are not at risk for magnesium deficiency because it is found in a variety of foods. However, certain groups of people may be more likely to experience low magnesium levels, including those with gastrointestinal disorders, type 2 diabetes, and chronic kidney disease. Symptoms of magnesium deficiency can include:

#1 Muscle cramps or spasms

Muscle cramps or spasms are one of the most common symptoms of low magnesium. Magnesium is required for muscle contraction and relaxation, so when levels are low, muscles may contract involuntarily or spasm. This can cause pain, stiffness, and difficulty moving the affected muscle. In severe cases, low magnesium may cause muscle weakness and paralysis.

#2 Tiredness and Persistent fatigue

When you don’t have enough magnesium in your body, it causes fatigue. Magnesium is important for the proper functioning of muscles, including the heart. It helps to convert blood sugar into energy and regulates blood pressure. A lack of magnesium can also lead to anxiety, depression, and trouble sleeping. The recommended daily allowance for magnesium is 400 mg for adults.

#3 Osteoporosis

Low magnesium levels can contribute to osteoporosis in a number of ways. First, magnesium is necessary for the absorption and utilization of calcium. Without adequate magnesium, calcium cannot be properly utilized by the body and may instead contribute to the calcification of soft tissues.

Additionally, magnesium is necessary for the proper formation and maintenance of bone. Low magnesium levels can therefore lead to a decrease in bone density and an increased risk for fractures.

Besides this, magnesium plays a role in the regulation of hormone levels, including estrogen. Estrogen is important for the health of bones, and subclinical magnesium deficiency can lead to a decrease in estrogen levels, which can further contribute to osteoporosis.

#4 High blood pressure

Magnesium is an important mineral for the proper functioning of the body. It helps to maintain normal blood pressure and reduces the chance of cardiovascular disease. Low magnesium levels can cause high blood pressure leading to heart disease. Magnesium supplements can help to lower blood pressure.

#5 An irregular heartbeat (Arrhythmia)

Now that we know how magnesium affects the heart, let’s take a look at how low magnesium can cause an irregular heartbeat.

Magnesium is responsible for keeping the heart’s electrical system functioning properly. When magnesium levels are low, this can cause the electrical system to become unbalanced, which can lead to an irregular heartbeat.

Firstly, low magnesium can cause the heart to beat too fast (tachycardia). Secondly, low magnesium can cause the heart to beat too slowly (bradycardia).

#6 Asthma

Magnesium deficiency can cause asthma. One is by causing the smooth muscle in the airways to constrict, which makes it difficult to breathe. Moreover, it can cause inflammation in the airways, making it even more difficult to breathe. Asthma is a chronic condition that can be serious, so it is important to make sure that you are getting enough magnesium in your diet.

Causes of Low Magnesium

There are a variety of things that can lead to low magnesium levels. Some causes are more common than others.

One potential cause is poor diet. If you don’t consume enough magnesium rich foods, it can lead to deficiencies. This is especially true if you eat a lot of processed foods, as they often lack magnesium.

Certain medical conditions can also lead to low magnesium levels. For example, gastrointestinal disorders like Crohn’s disease can interfere with the absorption of magnesium from food. Kidney problems can also cause magnesium levels to drop, as the kidneys play a role in excreting excess magnesium from the body.

Besides this, certain medications can also cause magnesium levels to decline. Diuretics, for example, can lead to magnesium loss through increased urination. Some antibiotics can also cause problems, as they can kill the helpful gut bacteria that help with magnesium absorption.

Finally, certain lifestyle factors can also contribute to magnesium deficiency symptoms. Excessive alcohol consumption, for example, can lead to magnesium deficiencies.

Diagnosing Low Magnesium Levels

When it comes to diagnosing magnesium deficiency, it can be tricky because the symptoms are often nonspecific, which means they can mimic other disorders. A blood test is the most reliable way to diagnose a magnesium deficiency. However, blood tests may not be able to tell you how severe the deficiency is or what’s causing it.

Treatment for Magnesium Deficiency
