Diabetes is a condition that affects the way the body regulates and uses blood sugar. When blood sugar levels remain too high for too long, people with diabetes can develop complications that contribute to feelings of fatigue. This is known as diabetes fatigue syndrome (DFS) or diabetes-related fatigue. While the exact mechanism behind DFS is not fully understood, it is thought to be related to biochemical and ionic changes in muscles, which impact their electrical and contractile properties. Additionally, high blood sugar can damage nerves and interfere with their ability to send signals, leading to a condition called diabetic neuropathy, which may also contribute to muscle fatigue.

Diabetes fatigue syndrome
Diabetes is a condition where the body either does not produce enough insulin or does not use insulin effectively. This results in excess glucose in the blood. Diabetes fatigue syndrome (DFS) is a term used to describe the occurrence of fatigue in persons with diabetes. It is a multifactorial syndrome that may be caused by a variety of lifestyle, nutritional, medical, psychological, and endocrine factors.
Fatigue is a common symptom of both type 1 and type 2 diabetes and can significantly impact a person's quality of life. High blood sugar levels, depression, obesity, and other related health conditions are some of the common causes of diabetes fatigue. Additionally, certain medications used to treat diabetes and other health issues can lead to fatigue as well. For example, long-term use of corticosteroids can cause fatigue if the dosage is reduced too quickly or if they affect blood sugar levels. Similarly, diuretics, which are used to treat high blood pressure, can also contribute to fatigue as they increase urine output.
Furthermore, there is a bidirectional relationship between diabetes distress and easy fatigability. Diabetes distress refers to the emotional and mental difficulties that a person with diabetes may experience. Feelings of frustration and worry can adversely affect a person's well-being and ability to manage their diabetes, leading to higher risks of complications and, consequently, increased fatigue.
Lack of physical conditioning, poor sleep hygiene, substance abuse, and unhealthy diets are also factors that can contribute to DFS. Additionally, DFS may be related to common medical conditions such as anemia, dyselectrolytemia, and multiple vitamin deficiencies.

High blood sugar and nerve damage
High blood sugar can cause nerve damage, a condition known as diabetic neuropathy. This is an often preventable complication of diabetes. Diabetic neuropathy can manifest in several types, depending on which nerves are affected. The symptoms of nerve damage include loss of feeling or numbness, a tingling or burning sensation, sharp pains or cramps, and muscle weakness.
The exact cause of each type of neuropathy is unknown, but researchers believe that persistently high blood sugar levels over time damage nerves and interfere with their ability to transmit signals, potentially leading to diabetic neuropathy. High blood sugar also weakens the capillaries, which are small blood vessels that supply nerves with oxygen and nutrients. This interference with nerve function can result in serious medical conditions.
People with autonomic neuropathy, for example, may not experience warning signs of low blood sugar, such as shakiness, sweating, or a fast heartbeat. Nerve damage can also cause a loss of feeling in the feet, allowing minor cuts to develop into sores or ulcers without being noticed. Infections in these cases can spread and lead to tissue death, possibly requiring amputation of the affected area. Additionally, if the nerves controlling the bladder are damaged, it may not empty fully when urinating.
Managing blood sugar levels and adopting a healthy lifestyle are crucial steps to prevent nerve damage and its associated complications. Maintaining blood sugar levels within a healthy range can reduce the risk of nerve damage and other medical issues related to diabetes.

Diabetes distress and mental health
High blood sugar levels can cause muscle fatigue. People with diabetes can develop complications that contribute to feelings of fatigue. This happens when blood sugar levels remain high for a long period. Diabetes medications can also cause low blood sugar, which can lead to fatigue.
Diabetes distress is a condition that can occur in people with diabetes, characterised by feelings of frustration and worry related to living with the disease. It shares some traits with stress, depression, and anxiety, and can be caused by fear of blood sugar fluctuations and the day-to-day responsibility of managing the condition. The CDC estimates that within an 18-month period, one-third to half of people with diabetes experience diabetes-related distress. Diabetes distress can be addressed by improving diabetes management to reduce stress, as well as through talk therapy and support groups.
Mental health issues are more common in people with diabetes, who are 2 to 3 times more likely to experience depression than those without the disease. Untreated mental health issues can negatively impact diabetes management and vice versa. Low rates of detection of mental health conditions in people with diabetes are a challenge, with only around one-third receiving a diagnosis and proper treatment. This may be due to the overlap in symptoms when blood sugar is too high or too low, as well as stigma and reluctance to discuss mental health.
To improve mental health and diabetes management, it is important to seek help from a mental health professional and to incorporate tools and tips to support well-being into your routine. Regular screenings for mental health conditions during office visits are recommended, as well as dialectical behavioural therapy (DBT) and, in some cases, medication. By prioritising mental health and diabetes management together, individuals can improve their overall health and well-being.

Poor lifestyle choices
Unhealthy lifestyle choices, such as inappropriate diets, can lead to DFS. Poor dietary choices can result in malnutrition or starvation ketosis, which can contribute to high blood sugar levels and fatigue. Additionally, substance abuse, including excessive alcohol and caffeine consumption, can be a factor in DFS. These substances can disrupt sleep patterns, leading to fatigue.
Lack of physical conditioning is another lifestyle factor that can contribute to DFS and high blood sugar levels. Engaging in physical activity helps manage blood sugar levels and reduces the risk of complications. However, fatigue can be a significant barrier to physical activity, creating a vicious cycle.
Furthermore, poor sleep hygiene is a lifestyle factor that can exacerbate DFS. Sleep disturbances are common in people with diabetes, as they may experience frequent nighttime awakenings and discomfort. Poor sleep quality can contribute to feelings of fatigue and exhaustion.
It is important to address these poor lifestyle choices through lifestyle modifications and nutritional interventions to help manage both diabetes and symptoms of fatigue.

Diabetes medication side effects
Diabetes is a condition that affects the body's ability to regulate blood sugar, which can lead to fatigue and other complications. While diabetes medications can help manage blood sugar levels, they may also have side effects that vary depending on the specific medication and the individual's response to it. Here are some common diabetes medication side effects:
- Metformin: This medication is commonly prescribed as a first-line treatment for type 2 diabetes. While it is generally well-tolerated, some people may experience gastrointestinal problems such as abdominal pain, nausea, bloating, and diarrhoea, especially when consuming high-carbohydrate meals. It can also cause a loss of appetite, a metallic taste in the mouth, and in rare cases, vitamin B12 deficiency. Hypoglycaemia (low blood sugar) is uncommon with metformin but more likely when combined with other diabetes medications or alcohol consumption.
- SGLT2 Inhibitors: These medications can be beneficial for people with Type 1 and Type 2 diabetes. However, they may lead to diabetic ketoacidosis (DKA), even if blood glucose levels are well-controlled. If symptoms of DKA occur, it is crucial to stop taking the medication and seek immediate medical attention.
- Prandial Glucose Regulators: While generally safe, these medications can also cause hypoglycaemia, especially when combined with sulfonylureas.
- Beta-Blockers: Recommended for individuals with high blood pressure and anxiety, beta-blockers can slow the heart rate, potentially leading to chronic fatigue.
- Corticosteroids: Used to treat inflammation, pain, and discomfort associated with other conditions, corticosteroids can cause fatigue if the dosage is reduced too quickly or if they affect blood sugar levels.
- Diuretics: Commonly used to treat high blood pressure, diuretics can increase urine output, which may contribute to fatigue in individuals with diabetes.
It is important to remember that not everyone will experience all or any of these side effects, and the benefits of medication often outweigh the risks. However, if you are experiencing any symptoms or side effects, it is crucial to consult your healthcare provider. They can work with you to adjust dosages, change medications, or add complementary treatments to optimise your diabetes management while minimising side effects.
