Feeling Tired? Check the Early Signs of Diabetes in Men

Are you feeling constantly tired and wondering what might be causing it? It could be crucial to recognize the early signs of diabetes in men. From persistent tiredness to increased thirst, understanding these symptoms can help you manage your health proactively. Explore the telltale signs and empower yourself to make informed choices for a healthier, more energized life.

Understanding Diabetes

Before we explore the signs and symptoms of diabetes, it's essential to understand the condition itself. Diabetes is a chronic metabolic disorder characterized by elevated blood sugar levels, primarily caused by insulin-related issues. Insulin, a hormone produced by the pancreas, helps regulate blood sugar (glucose) and allows it to enter cells to provide food and energy. In diabetes, there's either a lack of insulin production or resistance to insulin's effects, leading to an imbalance in blood sugar levels.

Diabetes is broadly categorized into two main types:

  1. Type 1 Diabetes: This form of diabetes is an autoimmune condition in which the body's immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. People with type 1 diabetes require lifelong insulin therapy.
  2. Type 2 Diabetes: Type 2 diabetes is more common and is characterized by insulin resistance, where the body's cells don't respond effectively to insulin. It often develops in adults but is also increasingly diagnosed in younger individuals.
  3. Gestational diabetes: It is a type of diabetes that develops during pregnancy when a woman's body cannot produce enough insulin to meet increased needs, leading to elevated blood sugar levels. It typically resolves after childbirth but requires careful monitoring and management to ensure a healthy pregnancy.

In all these types of diabetes, uncontrolled blood sugar levels can lead to various health complications, including cardiovascular disease, kidney problems, nerve damage, vision impairment, and more. Early detection and management of diabetes are critical in preventing these complications.

Risk Factors

Several factors can increase a person's risk of diabetes to increase, including:

Age: The risk of developing type 2 diabetes increases with age. Adults over the age of 45 are at an increased risk, and the risk rises further after age 65.

Family history: Having a family history of diabetes, especially a parent or sibling with type 2 diabetes, increases your risk factors for prediabetes.

Ethnicity: People of certain ethnicities, including African Americans, Pacific Islanders, Alaska Natives, Hispanics/Latinos, American Indians, and Asian Americans, are at an increased risk of developing type 2 diabetes.

Overweight or obesity: Being overweight or obese is a significant risk factor for type 2 diabetes. Having a body mass index (BMI) of 30 or higher significantly increases your risk.

Physical inactivity: Lack of physical activity increases your risk of developing type 2 diabetes. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.

Gestational diabetes: Women who have had gestational diabetes, a type of diabetes that develops during pregnancy, are at an increased risk of developing type 2 diabetes later in life.

Polycystic ovary syndrome (PCOS): Polycystic ovarian syndrome is a hormonal disorder that can cause insulin resistance and an increased risk of type 2 diabetes.

Mental health conditions: People with certain mental health conditions, such as schizophrenia and bipolar disorder, are at an increased risk of developing type 2 diabetes.

It is important to note that having one or more risk factors does not mean you will develop diabetes. However, it is essential to be aware of your risk factors so that you can take steps to reduce complications of diabetes and manage your health.

Fatigue as an Early Sign of Diabetes in Men

Fatigue, the overwhelming and persistent feeling of tiredness, is one of the earliest and most common symptoms of Type 2 diabetes, which is a chronic disease, particularly in men. While occasional fatigue is a part of everyday life, diabetes-related fatigue tends to differ. It can be chronic, unexplained, and often not relieved by rest or a good night's sleep. Here's why fatigue can be a telling sign of diabetes:

Energy Utilization

In diabetes, the body's inability to effectively use glucose for energy to do physical activity can lead to persistent tiredness. When blood sugar levels are high, this extra glucose or excess sugar isn't efficiently transported into cells, depriving the body's tissues of their primary energy source.


Frequent abnormal urination is another diabetes symptom. As excess glucose is expelled through urine, it can lead to dehydration, causing further fatigue. The body needs adequate hydration to function optimally. This can eventually lead to dehydrated and itchy skin.

Weight Loss

In some cases, individuals with diabetes may experience unexplained weight loss. This can be due to the body breaking down fat and muscle tissue for energy because it can't use glucose efficiently. Weight loss can contribute to a feeling of weakness and fatigue.

Sleep Disturbances

Diabetes can lead to sleep disturbances, such as frequent nighttime urination and sleep apnea. Poor-quality sleep can leave individuals feeling tired and groggy during the day.

Other Common Early Signs of Diabetes

While fatigue is a prominent early sign and symptom of diabetes in men, several other symptoms of prediabetes include:

Increased Thirst and Frequent Urination

One of the hallmark symptoms of diabetes is polydipsia, which is extreme thirst. It often accompanies polyuria or excessive urination. High blood sugar levels can lead to the kidneys' inability to reabsorb glucose effectively, causing more frequent urination. This excessive thirst, in turn, triggers thirst as the body attempts to compensate for fluid loss.

Unexplained Weight Loss

People with diabetes can experience unexplained loss of body weight, particularly in the context of increased thirst and frequent urination, which can be a sign of diabetes. When the body can't use glucose as fuel for energy, it resorts to breaking down fat and muscle, leading to unintended weight loss.

Increased Hunger

Despite feeling tired and losing weight, diabetes increases hunger. This paradoxical symptom occurs because the body's cells are not receiving the energy they need due to insulin resistance or insufficient insulin production.

Blurred Vision

High blood sugar levels can lead to changes in the shape of the eye's lens, causing temporary blurry vision. As blood sugar levels stabilize, vision usually returns to normal. However, uncontrolled diabetes over an extended time can lead to a more severe and permanent eye condition. 

Slow-Healing Wounds

Diabetes can affect the body's ability to heal wounds, making injuries, cuts, or sores take longer to mend. Poor blood circulation and compromised immune function are contributing factors.

Numbness and Tingling

Nerve damage, known as diabetic neuropathy, is a common side effect of uncontrolled diabetes. It can lead to numbness, tingling, or burning sensations, often in the feet and hands.

Erectile Dysfunction

Men with diabetes may experience adverse effects such as erectile dysfunction, as high blood sugar levels can damage blood vessels and nerves. This can affect sexual function and lead to impotence.

Acanthosis nigricans (AN)

Acanthosis nigricans (AN) is a skin condition that causes dark, velvety patches to form on the skin. These patches are commonly found in skin folds like the neck, armpits, and groin.

AN is not a disease but rather a symptom of an underlying condition. The most common cause of AN is insulin resistance, in which the body's cells do not respond normally to insulin. Insulin is a hormone that helps the body use glucose for energy. When the body is resistant to insulin, glucose levels in the blood can rise, leading to prediabetes or type 2 diabetes.

AN can also be caused by other conditions, such as obesity, polycystic ovary syndrome (PCOS), and certain medications. In rare cases, AN can be a sign of cancer.

The appearance of AN can be an early sign of prediabetes or type 2 diabetes. However, it is essential to note that not everyone with AN will develop diabetes. Many people with AN do not have diabetes or any other underlying health condition.

Increased Infections

People with diabetes are more susceptible to infections, such as skin allergies or skin infections, fungal infections in feet, urinary tract infections(yeast infection), and genital areas. High blood sugar levels create an environment where bacteria and fungi thrive.

When to See a Doctor

Suppose you or someone you know is experiencing persistent fatigue, increased thirst, frequent urination, unexplained weight loss, or any of the other symptoms mentioned. In that case, seeking medical attention from a healthcare provider is crucial. Early diagnosis and management of diabetes can significantly reduce the risk of complications.

Long-term Effects of Diabetes on Men

The long-term health conditions in men underscore the importance of proactive management and control of blood sugar levels through a healthy diet, healthy weight, lifestyle modifications, medications, and regular medical check-ups. Early detection and intervention are crucial in minimizing these risks of Type 2 diabetes and improving the overall quality of life.

  1. Cardiovascular Complications:
    • Heart Disease: Men with diabetes have a significantly increased risk of developing heart disease. High levels of blood glucose can damage blood vessels and blood flow, leading to atherosclerosis (hardening and narrowing of the arteries), which increases the likelihood of heart attacks and chest pain (angina).
    • Stroke: High levels of blood sugar can contribute to the development of blood clots or cause damage to blood vessels in the brain, increasing the risk of stroke.
    • Hypertension: High blood pressure is a common complication of diabetes, further straining the cardiovascular system.
  2. Nerve Damage (Neuropathy):
    • Peripheral Neuropathy: This condition affects the nerves in the extremities, particularly the feet and legs. It can result in pain, tingling, numbness, or loss of sensation. Foot ulcers, which are common in diabetic individuals, can go unnoticed due to neuropathy and may lead to infections and even amputations that need immediate medical care.
    • Autonomic Neuropathy: It can impact the nerves that control essential bodily functions, leading to digestive problems, issues with blood pressure regulation, and sexual dysfunction.
  3. Amputation:
    • Nerve damage and impaired blood circulation, often seen in diabetes, can lead to slow wound healing, particularly in the feet. If left untreated, minor foot injuries can get infected and develop into ulcers. In severe cases, when these ulcers don't heal with medical treatment, amputation may be necessary to prevent the spread of infection.
  4. Overall Reduced Quality of Life:
    • Managing diabetes can be physically and emotionally taxing, affecting an individual's overall quality of life. Constant monitoring of blood sugar levels, dietary restrictions, medications, and the risk of complications can lead to increased stress and anxiety.
    • The burden of managing the condition and its potential limitations on daily life, including dietary restrictions and lifestyle modifications, can impact a person's emotional well-being and overall satisfaction.
  5. Kidney Problems:
    • Diabetes is one of the leading causes of kidney damage. Over time, elevated blood sugar levels can damage the small blood vessels in the kidneys, affecting their ability to filter waste and excess fluids from the body. This can lead to a common type of chronic diabetic kidney disease, kidney failure, and the need for dialysis or transplantation. In some cases, a kidney transplant may be necessary.
  6. Vision Impairment:
    • Diabetic Retinopathy: High blood sugar levels can damage the blood vessels in the retina, leading to diabetic retinopathy. This condition can cause vision problems, including blurred or distorted vision. In advanced stages, it can lead to blindness.
    • Cataracts and Glaucoma: Individuals with diabetes have an increased risk of developing cataracts and glaucoma, further impacting vision.

Blood tests

Several detailed and routine blood tests can be used to diagnose diabetes in men that can be discussed with your healthcare team. These tests include:

  • Fasting plasma glucose (FPG) test: This test measures your proper blood glucose level after you have not eaten for at least 8 hours. A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher on two separate tests indicates diabetes.
  • Random plasma glucose (RPG) test: This test measures your blood sugar level at any time of day. A random blood sugar level of 200 mg/dL (11.1 mmol/L) or higher indicates diabetes.
  • Oral glucose tolerance test (OGTT): This test measures your blood sugar level before and after you drink a sugary drink. An OGTT blood sugar level of 140 mg/dL (7.8 mmol/L) or higher two hours after the sugary drink indicates diabetes.
  • Glycated haemoglobin (A1C) test: This test measures the average sugar levels in people attached to haemoglobin, the protein in red blood cells, over the past 2-3 months. An A1C level of 6.5% or higher indicates diabetes.

In addition to these blood tests, blood glucose meters, reagent strips, and urine glucose tests may also help to rule out other causes of your symptoms, such as thyroid problems or liver disease.

Treatment for Diabetes in Men

The goal of diabetes treatment is to control your blood sugar levels to prevent complications of Type 2 diabetes. Diabetes treatment may include lifestyle changes, medication, or both.

Lifestyle changes

The following lifestyle changes can help to control your blood sugar levels:

  • Eat a healthy diet. Choose meals for diabetes that are low in sugar and fat and high in fibre. You should get half of your daily calories from carbs or carbohydrate content. Drinking a sufficient amount of water prevents the onset of hyperglycemia. Avoid foods that have simple carbohydrates, such as white bread, pizza, pastries, and other fatty foods. These high glycemic index foods cause blood sugar spikes.
  •  Exercise regularly. Aim for at least 30 minutes of moderate-intensity regular exercise most days of the week. Pain management exercises can help relieve pains due to diabetic peripheral neuropathy.
  • Lose weight if you are overweight or obese. Maintain appropriate body weight by keeping track of food choices. Even losing a small amount of weight can help to improve your blood sugar control.
  • Monitor your blood sugar levels. Check your levels of sugar as often as your healthcare professional recommends to avoid blood sugar spikes and control in people with diabetes.
  • Quit smoking. Smoking can worsen diabetes control.


Several medications can be used to treat diabetes. The type of medication that is best for you will depend on your individual needs. Some common medications for diabetes include:

  • Insulin. Insulin is a hormone that helps your body use glucose for energy. Adults with type 1 diabetes need to take insulin to survive. Some people with type 2 diabetes may also need to take insulin to maintain blood glucose in the target range for patients.
  • Oral medications. Several different oral diabetes medications can be used and advised by the diabetes care team to treat type 2 diabetes. These medications work in different ways to lower blood sugar levels in the blood cells and must be used at any time of day.
  • Non-insulin injectable medications. There are a few different types of non-insulin injectable medications that can be used to treat type 2 diabetes. These medications work in different ways to lower blood sugar levels.

Other treatments

In addition to lifestyle changes and medication, other treatment options may be helpful for people with diabetes. These treatments may include:

  • Diabetes self-management education (DSME). DSME is an Adult Education Programme that can teach you how to manage your diabetes.
  • Support groups. Support groups can provide you with information and support from other people with diabetes.

Normal Range

The American Heart Association (AHA) is a leading organization for cardiovascular health and stroke research. They provide guidelines and recommendations for various topics, including blood sugar levels.

According to the AHA, the following are the healthy ranges for blood sugar levels:

For adults without diabetes:

  • Fasting blood glucose: 70 to 99 mg/dL (3.9 to 5.6 mmol/L)
  • Two hours after eating: Less than 140 mg/dL (7.8 mmol/L)
  • Glycated haemoglobin (A1C): Less than 5.7%

For adults with diabetes:

  • Fasting blood glucose: 90 to 130 mg/dL (5.0 to 7.2 mmol/L)
  • Two hours after eating: Less than 180 mg/dL (10.0 mmol/L)
  • Glycated haemoglobin (A1C): Less than 7.0%

These are just general guidelines, and your doctor may recommend different target blood sugar levels for you based on your individual circumstances.

According to the International Diabetes Federation (IDF), the global prevalence of diabetes in 2019 was 9.3%, representing 463 million adults aged 20-79 years. This number is expected to rise to 10.2% (578 million) by 2030 and 10.9% (700 million) by 2045.

The prevalence of diabetes is higher in urban (10.8%) than rural (7.2%) areas and in high-income (10.4%) than in low-income countries (4.0%). One in two (50.1%) people living with diabetes do not know that they have diabetes.

The IDF also estimates that there are 374 million people with impaired glucose tolerance (IGT), a condition that is a precursor to diabetes. IGT is estimated to affect 7.5% of adults aged 20-79 years worldwide.


Feeling tired all the time can be a sign of many health issues, and when it comes to diabetes, recognizing this early symptom is crucial. The early signs of diabetes in men, including fatigue, increased thirst, and frequent urination, can often be subtle and mistaken for other concerns. However, understanding these red flags and paying attention to your body's signals is the first step in taking control of your health. If you suspect you may have diabetes, don't delay—seek medical advice, get tested, and take proactive steps to manage this condition. With early intervention and proper care, individuals with diabetes can lead healthy and fulfilling lives while reducing the risk of complications.


What are the 3 early warning signs of kidney disease?

Changes in urination: Frequent urination, especially at night, or passing urine that is foamy, bloody, or dark in colour.
Fatigue and weakness: Feeling tired or weak, even after getting enough sleep.
Swelling in hands, feet, or ankles: Puffiness in the hands, feet, or ankles, especially in the morning.

What foods help repair kidneys?

Eating a healthy diet rich in fruits and vegetables, such as berries, apples, oranges, leafy greens, and vegetables, can help to repair kidneys. Fruits and vegetables are low in phosphorus, a mineral that can build up in the kidneys if a person has kidney disease.

What is acute kidney injury?

Acute kidney injury (AKI) is a sudden decrease in the kidney's ability to filter waste products from the blood. This can lead to a buildup of toxins in the blood and can cause serious complications. A variety of factors, including dehydration, infection, and certain medications, can cause AKI.

What are the foods that people with diabetes must avoid?

People with diabetes should avoid foods with unhealthy carbs that are high in sugar, fat, and sodium. This includes sugary drinks, processed foods, and fast food. Instead, they should focus on eating whole meal options, unprocessed foods, such as fruits, vegetables, and whole grains.
