Contrary to popular belief, fatigue, and tiredness do not mean the same. Tiredness can be alleviated by rest, but fatigue often continues regardless of rest and can lead to long-term feelings of lethargy and exhaustion. Fatigue is a common symptom that can significantly impact an individual’s quality of life. It is advisable to consult with your doctor to determine the underlying cause of your fatigue and explore appropriate solutions.

Fatigue Signs

Fatigue goes beyond mere sleepiness, occasional energy depletion, or an irresistible urge to sleep. It presents as a pervasive lack of both emotional and physical energy, which can significantly impact one's ability to perform daily activities. Typical symptoms of fatigue include:

• Weakness
• Exhaustion
• Lack of energy
• Tiredness
• Difficulty concentrating
• Lack of motivation

In some cases, fatigue can also manifest as changes in mood, a decrease in physical and mental responsiveness, or headaches.

Why Does Diabetes Cause Fatigue?

There can be various reasons behind diabetes resulting in fatigue. These include:

1. Blood Sugar Fluctuations

• Diabetes affects the body's ability to regulate and utilize blood sugar effectively. After a meal, food is broken down into glucose, a simple sugar. With the help of insulin, glucose is absorbed by the cells to produce energy. However, in diabetics, either the pancreas doesn't produce sufficient insulin or the body is unable to use it efficiently, resulting in excess glucose in their bloodstream. Insufficient glucose in the cells can lead to fatigue and weakness.
• Similarly, diabetes medications, like metformin or insulin, help enhance the movement of sugar into cells, preventing its accumulation to harmful levels. However, a possible side effect of these medications is low blood sugar, also known as hypoglycemia. Hypoglycaemia can contribute to fatigue, particularly in individuals who experience frequent episodes and may not receive sufficient warning signs of dropping blood sugar levels. Even after receiving treatment for hypoglycemia, a person may continue to experience fatigue.

2. Other Symptoms of Diabetes 

Other symptoms of diabetes can contribute to a person's overall feeling of being unwell, causing them to experience fatigue. These symptoms include:

• Frequent urination
• Extreme hunger even after eating
• Excessive thirst
• Blurred vision
• Unexplained weight loss

While not all of these symptoms directly cause fatigue, they can contribute to a sense of discomfort and unease, which may lead to the development of fatigue. 

Furthermore, some symptoms of diabetes can disrupt an individual’s sleep pattern. For instance, individuals with diabetes may wake up multiple times during the night to urinate or quench their thirst. Discomfort in the limbs, feet, and hands can also make it difficult for people with diabetes to fall asleep and remain asleep. These sleep disturbances can further contribute to feelings of fatigue.

3. Complications of Diabetes 

People with diabetes may experience complications that can result in feelings of fatigue and persistent exhaustion. These complications often arise when blood sugar levels remain elevated for an extended period. Some potential complications include that can cause fatigue include:

• Frequent infections
• Kidney problems, such as kidney failure
• Blindness
• Nerve damage (diabetic neuropathy)
• Heart disease

4. Side Effects of Diabetes Medications

Certain medications, which are used to treat diabetes complications and the condition itself, can have side effects that lead to fatigue. Here are some examples of medications that may cause fatigue:

• Corticosteroids: These medications are commonly prescribed to manage pain and inflammation. Abrupt reduction of corticosteroid dose after prolonged use or the impact of these medications on sugar levels can lead to fatigue.
• Statins: Statins are prescribed to lower levels of LDL cholesterol (bad cholesterol). While statins are generally well-tolerated, some people may experience fatigue.
• Diuretics: Diuretics are commonly used to treat high blood pressure by promoting increased urine production. However, the frequent urination caused by diuretics can lead to disruption of sleep and dehydration, resulting in fatigue.
• Beta-blockers: Beta-blockers are prescribed to manage anxiety and high blood pressure by slowing down the heart rate and reducing the force of contractions. These medications can sometimes cause chronic fatigue as a side effect due to their impact on heart rate.

5. Mental Health

Studies have shown that diabetics are more likely to experience depression compared to those without the condition. A study involving 90,686 participants revealed that people with diabetes may be approximately 2-3 times more likely to suffer from depression. Depression can contribute to feelings of fatigue, as many of its symptoms can cause a lack of energy. Some of these symptoms include:

• Changes in sleep patterns
• Changes in diet that impact glucose levels
• Being unable to go back to sleep or waking too early 

6. Having Higher Than Normal Body Fat

A significant proportion of individuals diagnosed with type 2 diabetes are obese or overweight. People who have obesity may face challenges when it comes to participating in physical activities. They may also experience disruptions in their sleep patterns and have an unbalanced diet. These factors can contribute to feelings of fatigue and tiredness.

How to Deal with Diabetes Fatigue?

Here are some measures you can take to manage fatigue caused by diabetes:

1. Make Healthy Lifestyle Changes

Making positive lifestyle changes is crucial for overall well-being as it can help combat fatigue associated with diabetes. These changes encompass various aspects, including regular exercise, nutritious eating, and weight management, which can enhance energy levels and help regulate blood sugar. Implementing effective lifestyle adjustments may involve:

• Engaging in regular exercise
• Maintaining a healthy weight
• Following a nutritious diet
• Managing stress
• Practising good sleep hygiene by establishing consistent bedtimes
• Ensuring proper hydration

2. Properly Manage Your Diabetes 

To effectively combat fatigue associated with diabetes, it is crucial for individuals to actively manage their condition and any related complications. This involves implementing the following measures:

• Regularly monitor blood sugar levels to ensure they remain within the target range.
• Follow a balanced diet that restricts simple sugars and refined carbohydrates, focusing on nutritious food choices.
• Adhere to the prescribed diabetes medications and closely follow the instructions provided by the doctor.
• Seek appropriate treatment for related complications, such as kidney disease, depression, or cardiovascular disease, by consulting with healthcare professionals.

3. Seek Social Support

A study involving adults suffering from type 2 diabetes revealed that receiving support from family and other sources can alleviate fatigue associated with diabetes. It is important to have open conversations with your family to ensure they are supportive of your diabetes management and overall care. Whenever possible, make an effort to spend time with friends and engage in activities that bring you joy and energy. 

4. Focus on Mental Health

Diabetics are at increased risk of developing mental health disorders such as depression. If you are currently undergoing treatment for depression, it is possible that your antidepressant medication could affect your sleep patterns. Discuss the possibility of switching medications with your doctor to see if it improves your sleep quality. Regular exercise has been shown to boost serotonin levels, which can help alleviate symptoms of depression and anxiety. Additionally, seeking to counsel from a therapist, either in a group setting or through one-on-one sessions, may provide further support and benefit your overall well-being.
