What You'll Learn
Diabetes and low blood sugar
Diabetes is a chronic disease that affects the body's ability to use blood sugar (glucose) for energy. Blood sugar is the main source of fuel for the body and brain. When blood sugar levels drop below a healthy range, it can lead to a condition called hypoglycemia, or low blood sugar. This can occur when the body produces too much insulin, which is a hormone that regulates blood sugar levels. For many people, hypoglycemia is defined as a blood sugar level below 70 milligrams per deciliter (mg/dL) or 3.9 millimoles per liter (mmol/L). However, it's important to discuss your target range with your healthcare professional, as these numbers may vary for different individuals.
People with diabetes can experience low blood sugar as often as once or twice a week, even when they closely manage their blood sugar levels. Low blood sugar can be caused by various factors, including taking too much insulin or other diabetes medications, not eating enough carbohydrates, skipping meals, increased physical activity without adjusting medication or food intake, and drinking alcohol. It is important to understand the causes of low blood sugar to take preventive measures.
Symptoms of hypoglycemia can vary depending on the time of day and how long an individual has been experiencing low blood sugar. Early symptoms include hunger, upset stomach, a fast or irregular heartbeat, trouble concentrating, weakness and fatigue, irritability or anxiety, and tingling or loss of feeling in the lips, tongue, or cheeks. If hypoglycemia occurs during sleep, it can cause nightmares, sweating, and tiredness, irritability, or confusion upon waking up. Left untreated, hypoglycemia can lead to more severe symptoms, including confusion, unusual behavior, seizures, and loss of consciousness.
Low blood sugar can also cause muscle cramps, which are a relatively common manifestation in people with diabetes. These cramps tend to occur more frequently in the lower extremities and at night. Muscle cramps can result from glucose being required for muscles to properly contract and relax, as well as imbalances in electrolytes such as calcium, magnesium, and potassium. In addition, diabetes-related complications such as artery disease, peripheral vascular disease, and nerve damage can contribute to muscle cramps by reducing circulation to the muscles.
It is important to consult a healthcare professional if you are experiencing regular muscle cramps or other symptoms of hypoglycemia. Treatment for severe hypoglycemia may require the administration of glucagon, a hormone that causes the liver to release sugar into the blood. Maintaining a healthy diet, taking dietary supplements as advised by a doctor, and engaging in physical therapy or gentle exercises like walking can help prevent muscle cramps in people with diabetes.

Electrolyte imbalances
Electrolytes are minerals that carry an electric charge when dissolved in fluids like blood and urine. Electrolytes like sodium, potassium, magnesium, calcium, chloride, phosphate, and bicarbonate play a crucial role in maintaining nerve and muscle function, regulating fluids, and supporting metabolism.
An electrolyte imbalance occurs when the levels of these minerals in the body are either too high or too low. This can be caused by various factors, including excessive sweating, dehydration, prolonged vomiting or diarrhea, certain medications, and inadequate electrolyte intake, especially during exercise.
The symptoms of an electrolyte imbalance can vary depending on its severity and the type of electrolyte involved. In general, electrolyte imbalances can cause muscle cramps, weakness, and spasms. Specifically, a deficiency in calcium, known as hypocalcemia, can lead to muscle cramps as calcium is essential for nerve function and muscle contraction. Similarly, low levels of magnesium, or hypomagnesemia, can also contribute to muscle cramps as magnesium supports nerve and muscle function. Potassium is another critical electrolyte for nerve and muscle function, and imbalances can lead to muscle issues.
To prevent and manage muscle cramps caused by electrolyte imbalances, it is essential to maintain proper hydration and a balanced intake of electrolytes. This can be achieved through a diet rich in fruits, vegetables, nuts, seeds, and dairy products. In certain cases, such as for individuals engaging in intense exercise or those with specific health conditions like diabetes, additional supplementation may be recommended.

Dehydration
The dehydration theory suggests that decreases in body mass, blood volume, and plasma volume contribute to exercise-associated muscle cramps (EAMCs). Dehydration can occur for many reasons, including perspiration, caffeine consumption, and aging. Caffeine is a diuretic, which means that any fluids containing caffeine are likely to be excreted through urine. As we age, there is a tendency to become less well-hydrated.
The serum electrolyte theory suggests that decreases in the concentration of sodium, potassium, magnesium, chloride, and/or calcium in the blood can lead to EAMCs. This can occur due to sweating or overconsumption of water during exercise, causing an electrolyte imbalance in the body. Electrolytes are essential for the proper functioning of muscles, and when there is an imbalance, muscle cramping can occur.
To prevent muscle cramps caused by dehydration, it is important to stay well-hydrated, especially before, during, and after exercise. It is also beneficial to consume fluids containing electrolytes, such as Gatorade or pickle juice, to maintain proper electrolyte balance in the body.
In addition to hydration and electrolyte balance, other factors can contribute to muscle cramps. These include muscle fatigue, improper conditioning, prolonged exercise, sitting in one place for too long, and vascular disorders, all of which can decrease blood circulation to the muscles.

Nerve damage
Muscle cramps caused by nerve damage are often referred to as "secondary" leg cramps, indicating that they are a symptom or complication of a more serious health condition. In the case of diabetes, this can include peripheral vascular disease or diabetic neuropathy. Diabetic neuropathy can cause nerve damage, leading to muscle spasms and pain. It is crucial for individuals with diabetes to control their blood sugar levels to reduce the risk of further nerve damage and associated muscle cramps.
Cancer treatments, such as chemotherapy, can also cause nerve damage and subsequent leg cramps. Certain medications used to treat diabetes, such as insulin, lipid-lowering agents, and oral contraceptives, may further contribute to muscle cramps as a side effect. Additionally, conditions like amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease, which affect the nerves and muscles, can lead to muscle cramps as well.
While muscle cramps are typically not a cause for serious concern, chronic muscle cramps accompanied by symptoms like pain, muscle weakness, or poor coordination could indicate an underlying neurological issue. In such cases, it is recommended to consult a healthcare provider for evaluation and guidance. They may prescribe medications or suggest alternative treatments, such as physical therapy, to help manage the cramps and any associated symptoms.
To alleviate muscle cramps in the moment, gentle stretching, massage, and applying heat or ice to the affected area can provide relief. While there are no medications that can prevent muscle cramps 100% of the time, muscle relaxants and certain prescription drugs may help reduce their occurrence. Maintaining proper hydration, electrolyte balance, and adequate vitamin and nutrient intake are also important for preventing muscle cramps associated with nerve damage.

Medication
While low blood sugar can cause muscle cramps, this answer will focus on medication as a cause of muscle cramps, specifically in relation to diabetes.
Diabetes patients who experience muscle cramps may do so as a side effect of medication used to treat the disease. These medications include insulin, lipid (cholesterol) lowering agents, antihypertensives (blood pressure medications), oral contraceptives, and beta-agonists.
In addition, medication can be used to treat muscle cramps and pain caused by diabetic neuropathy, a serious but common complication of type 1 and type 2 diabetes. Doctors may prescribe pain medication, and dietary supplements such as vitamin B-12 and vitamin D, which may help support healthy nerve function. However, it is important to discuss supplements with your doctor before taking them, especially if you are already taking other medications.
Conservative treatment for diabetic neuropathy may involve the use of volar wrist splints, particularly at night, with or without non-steroidal anti-inflammatory drugs (NSAIDs). ALC (alpha-lipoic acid) may also help produce healthy nerve cells and reduce pain, but it can interact with blood-thinning medications.
Prevention
There are several ways to prevent muscle cramps caused by diabetes, including:
- Managing blood sugar levels
- Taking prescription or over-the-counter medications
- Taking dietary supplements
- Making lifestyle changes, such as adopting a healthy diet and increasing physical activity
