Muscle cramps can be caused by a variety of factors, including injuries, conditions, and activities. One possible cause of muscle cramps is hypoglycemia, or low blood sugar. This is often associated with diabetes, a chronic disease that affects the body's ability to use sugar for energy. Diabetes can cause nerve damage and poor circulation, which are likely instigators of muscle spasms. Diabetic neuropathy, in particular, has been associated with higher rates of muscle cramps. Additionally, certain medications used to treat diabetes, such as insulin, lipid-lowering agents, and oral contraceptives, can also lead to muscle cramps. While muscle cramps may be infrequent for people with or without diabetes, it is important to seek medical advice to diagnose and treat the underlying cause to prevent potential complications and permanent damage.

What You'll Learn

Hypoglycemia and diabetes
Hypoglycemia, or low blood sugar, is a condition where plasma glucose concentration is low, which may expose patients to harm. Diabetic hypoglycemia refers to low blood sugar levels in a person with diabetes. Blood sugar, also called glucose, is the main source of fuel for the body and brain. You can't function well if your blood sugar drops below a healthy range. For many people, hypoglycemia is a blood sugar level below 70 milligrams per decilitre (mg/dL) or 3.9 millimoles per litre (mmol/L). However, it's important to note that these numbers may vary for different individuals.
Hypoglycemia is quite common among people with type 1 diabetes or those with type 2 diabetes who are taking insulin or similar medications. It is important to understand what causes your blood glucose to drop so that you can take preventive measures. Low blood sugar can be treated with fast-acting carbs to prevent a severe hypoglycemia incident. Glucose tablets can be taken, or you can consume a source of simple sugar such as hard candy, fruit juice, or regular soda.
If you experience hypoglycemic symptoms several times a week, it is important to consult a healthcare professional. They may suggest changes to your treatment plan. Additionally, it is beneficial to educate yourself on the risk factors, warning signs, and treatment options for hypoglycemia. This knowledge can empower you to set personalized goals for glycemic control and effectively manage your condition.
People with diabetes can take several preventive measures to reduce the risk of muscle cramps. These include staying up to date with the latest research and breakthroughs, as inflammation is often associated with long-term conditions like diabetes. Additionally, massaging the affected muscle while stretching it out can help relieve the pain of muscle cramps. However, if you experience regular muscle cramps, consulting your diabetes care team is advisable. They can help ascertain the cause and determine if further treatment is required.

Neuropathy and nephropathy
Muscle cramps can be caused by low blood sugar, or hypoglycemia. This is often associated with diabetes, which can lead to diabetic neuropathy and nephropathy. Diabetic neuropathy is characterised by pain, numbness, and tingling in the extremities with slow nerve conduction. Diabetic nephropathy is characterised by increased urinary protein, loss of renal function, and excessive deposition of extracellular matrix proteins in the mesangium.
Up to 50% of all patients with diabetes develop neuropathy, and the prevalence of painful neuropathy ranges from 10 to 20% of patients. Diabetic nephropathy and neuropathy are significant microvascular complications of diabetes mellitus, contributing to substantial morbidity and mortality worldwide. These complications often reflect systemic microvascular and macrovascular dysfunction.
People with peripheral vascular disease or diabetic neuropathy may suffer from muscle cramps, with poor circulation and nerve damage likely to instigate spasms. Side effects from certain medications used to treat diabetes can also result in muscle cramps. These include insulin, lipid (cholesterol) lowering agents, antihypertensives (blood pressure medications), oral contraceptives, or beta-agonists.
It is important to note that muscle cramps can result from various injuries, conditions, or activities. Therefore, if you are experiencing regular muscle cramps, it is recommended to consult a healthcare professional for a proper diagnosis and treatment plan.

Dehydration and loss of electrolytes
Several studies have examined the link between dehydration, electrolyte imbalance, and muscle cramps. Some studies have found that dehydration alone may not be the sole cause of muscle cramps, as some individuals experienced cramps even when they were adequately hydrated and supplemented with electrolytes. However, it has been observed that water intake after dehydration can make muscles more susceptible to cramps, possibly due to the dilution of electrolytes in the body.
To prevent and relieve muscle spasms caused by dehydration and electrolyte imbalance, it is crucial to maintain proper hydration and electrolyte balance. This can be achieved by drinking fluids before and during exercise, sipping electrolyte-enhanced water throughout physical activity, and replenishing lost electrolytes immediately after exercise. Additionally, limiting caffeine and alcohol intake can help reduce the risk of dehydration and subsequent muscle spasms.
It is important to note that while dehydration and electrolyte imbalance can contribute to muscle spasms, other factors, such as nerve damage, diabetes-related artery disease, and certain medications, may also play a role in muscle cramping. Seeking medical advice and designing a treatment plan with a healthcare professional is essential to address the underlying causes of muscle spasms and prevent potential complications.

Medication side effects
Hypoglycemia, or low blood sugar, is a condition that is most common in people with diabetes. It can be caused by insulin or other medications used to treat diabetes, such as sulfonylureas (glyburide, glipizide, and glimepiride). Hypoglycemia can also be caused by certain non-diabetes medications, including beta-blockers, antibiotics, pentamidine, and quinine. People with liver or kidney issues, older people, pregnant women, and children may be more susceptible to developing hypoglycemia from non-diabetes medications. Additionally, beta-blockers and selective serotonin reuptake inhibitors (SSRIs) may mask the symptoms of hypoglycemia, such as a rapid heart rate.
For people with diabetes, hypoglycemia can occur when there is an imbalance between insulin and food intake, physical activity levels, and blood glucose monitoring. Taking too much insulin, incorrect insulin, or injecting it into the muscle instead of fat tissue can lead to hypoglycemia. Not timing insulin and carbohydrate intake correctly, such as by waiting too long to eat after taking insulin, can also contribute. Additionally, taking too high of a dose of oral diabetes medications, increased physical activity, alcohol consumption without eating, irregular eating habits, and not balancing meals with fat, protein, and fiber can be factors.
Certain genetic conditions, such as congenital hyperinsulinism in children, can also lead to hypoglycemia. Anorexia, especially in individuals with a low BMI, can result in low blood sugar. In rare cases, tumors can cause hypoglycemia by releasing excess insulin or insulin-like growth factors.
The treatment for hypoglycemia involves raising blood glucose levels as soon as possible. Consuming carbohydrates or sugar in any form, such as candy, glucose tablets, or sweet drinks, can provide quick relief. For more severe cases, intravenous (IV) dextrose and glucose infusions may be administered. Oral medications, such as diazoxide, and fast-acting glucagon injections are other treatment options.

Musculoskeletal causes
Muscle cramps can result from a variety of injuries, conditions, or activities. They can be due to serious conditions, and failure to seek treatment can result in serious complications and permanent damage.
- Failure to stretch and warm up a muscle before exercising.
- Dehydration, which can be life-threatening when severe and untreated. Dehydration leads to a loss of body fluids and electrolytes.
- Diabetes, a chronic disease that affects the body's ability to use sugar for energy. Diabetes-related artery disease may reduce circulation to a muscle and cause cramping. Diabetes medications can also cause muscle cramps.
- Not moving a muscle for a long period, which may lead to reduced circulation or a compressed nerve.
- Peripheral vascular disease, which can cause poor circulation and nerve damage, leading to muscle spasms.
- Neuropathy, which has been associated with higher rates of muscle cramps.
