A PET scan (positron emission tomography) is a type of imaging test that uses a radioactive tracer to look for changes in the function of cells and tissues. A tracer is a substance that is introduced into the body to make it easier to see certain areas or organs. The radioactive tracer used in PET scans emits positrons, which are tiny particles that collide with electrons in the body. This creates gamma rays that can be detected by a scanner and used to create images of the inside of the body. PET scans are often used to diagnose cancer because tumor cells typically have higher levels of activity than normal cells. They can also be used to check for treatment response, measure tumor size, and identify new tumors.

PET Scan is a nuclear medicine imaging test that uses a small amount of radioactive material, called a tracer, to look for disease in the body. A PET Scan can show how well organs and tissues are working. It can help find cancer, heart problems, and other diseases. A Positron Emission Tomography (PET) scan is a medical imaging test that helps physicians diagnose and treat diseases. PET scans use a small amount of radioactive material, called a tracer, to help physicians see how organs and tissues are functioning. The radioactive tracer is injected into the patient's body and travels to the organ or tissue being studied. Physicians can then see where the tracer collects on an image of the organ or tissue.

A PET scan is helpful in diagnosing cancer, heart disease, brain disorders, and other diseases. It can also help determine how well treatment is working. PET Scan is an acronym for Positron Emission Tomography. It's a type of medical imaging that uses a small amount of radioactive material to help diagnose and treat medical conditions. A PET scanner creates 3D images of the inside of the body. PET (positron emission tomography) scans use a small amount of radioactive material called a tracer to help doctors see certain areas of the body. The tracer is injected into a vein, and images are taken as it moves through the body.

PET scans are often used to find cancer because tumors absorb more of the radioactive material than normal tissue does. PET scans can also be used to measure blood flow, check how well drugs work, and see how active the brain is. A PET scan is a type of imaging test that uses radioactive tracers to look at the function and structure of organs and tissues in your body. A small amount of radioactive material is injected into your bloodstream and then scanned by a special camera. The camera creates pictures that show where the material has collected. This can help doctors see how well an organ is working or find tumors or other problems.

PET scan is short for positron emission tomography. It's a type of medical imaging that uses a radioactive tracer to look at organ function or tissue metabolism. The tracer is a small amount of radioactive material that's injected into the patient's bloodstream. It collects in organs and tissues, and a scanner detects the radiation emitted as it decays. This information is used to create cross-sectional images of the body that show how the organs and tissues are working. PET scans are most often used to detect cancer because tumors consume more energy than normal tissue and therefore have a higher metabolic rate. But they can also be used to evaluate other problems, such as heart disease, brain function, and joint damage.

PET scanning is a type of nuclear medicine imaging. A small amount of radioactive glucose (FDG) is injected into a vein and images are taken as the glucose moves through the body. Cancer cells use more energy than normal cells and therefore absorb more of the radioactive glucose. This allows tumors to be visualized on the scan. PET stands for Positron Emission Tomography. A PET scan is a medical imaging test that uses a radioactive tracer to look at organs and tissues inside the body. The tracer is injected into a vein, and images are taken as it moves through the body.

Diabetes Symptoms in Men: Early Warning Signs You Should Not Ignore

Diabetes is one of the fastest-growing health challenges worldwide, and men are particularly vulnerable to its long-term complications. In India, the burden of diabetes has increased sharply over the past two decades, driven by lifestyle changes, sedentary habits and dietary patterns. Despite this, many men remain unaware of early diabetes symptoms or delay medical consultation until complications develop.

Understanding diabetes symptoms in men is essential for early diagnosis, effective management and prevention of serious health consequences.

 

What Is Diabetes?

Diabetes is a chronic metabolic disorder characterised by high blood sugar levels due to:

  • insufficient insulin production
     

  • ineffective insulin action
     

  • or both
     

The most common form affecting men is type 2 diabetes, which is strongly linked to lifestyle factors.

 

Why Men Are at Higher Risk

Several factors increase diabetes risk in men:

  • higher abdominal fat accumulation
     

  • smoking and alcohol consumption
     

  • irregular eating patterns
     

  • work-related stress
     

  • lower healthcare-seeking behaviour
     

According to Indian Council of Medical Research data, a significant proportion of men remain undiagnosed until advanced stages.

 

Early Diabetes Symptoms in Men

Frequent Urination

Excess sugar in the blood causes kidneys to work harder, leading to increased urination, especially at night.

 

Excessive Thirst

Frequent urination leads to dehydration, causing constant thirst.

 

Fatigue and Weakness

Cells cannot utilise glucose efficiently, resulting in low energy levels and persistent tiredness.

 

Unexplained Weight Changes

Men may experience unexplained weight loss despite normal or increased appetite.

 

Increased Hunger

Insulin resistance prevents glucose from entering cells, triggering frequent hunger.

 

Diabetes Symptoms Unique or Commonly Seen in Men

Erectile Dysfunction

Diabetes damages blood vessels and nerves, leading to erectile dysfunction.

Studies show a strong association between diabetes and male sexual health problems.

 

Reduced Testosterone Levels

Men with diabetes often have lower testosterone, affecting libido, muscle mass and mood.

 

Decreased Muscle Strength

Poor glucose utilisation affects muscle health and physical stamina.

 

Skin and Infection-Related Symptoms

Slow-Healing Wounds

High blood sugar impairs wound healing, increasing infection risk.

 

Frequent Infections

Men with diabetes are more prone to:

  • skin infections
     

  • urinary tract infections
     

  • fungal infections
     

 

Vision and Nerve Symptoms

Blurred Vision

Fluctuating blood sugar affects eye lenses, causing blurred vision.

 

Tingling or Numbness

Nerve damage, known as diabetic neuropathy, causes tingling or numbness in hands and feet.

 

Why Diabetes Symptoms Are Often Ignored by Men

Many men dismiss symptoms as:

  • work-related fatigue
     

  • ageing
     

  • stress
     

This delay increases the risk of complications.

 

Long-Term Complications of Untreated Diabetes

If untreated, diabetes can lead to:

  • heart disease
     

  • kidney failure
     

  • nerve damage
     

  • vision loss
     

  • sexual dysfunction
     

According to WHO and Lancet studies, early detection significantly reduces complication risk.

 

Importance of Early Diagnosis

Early diagnosis allows:

  • better blood sugar control
     

  • lifestyle modification
     

  • prevention of organ damage
     

Routine screening is crucial, even in the absence of symptoms.

 

When Should Men Get Tested?

Men should consider testing if they:

  • are over 30 years old
     

  • have a family history of diabetes
     

  • are overweight
     

  • have a sedentary lifestyle
     

  • experience any warning signs
     

Annual screening is recommended for at-risk individuals.

 

Managing Diabetes After Diagnosis

Effective management includes:

  • healthy diet
     

  • regular physical activity
     

  • weight control
     

  • stress management
     

  • medical treatment as advised
     

Early management improves quality of life.

 

Role of Preventive Healthcare

Preventive healthcare focuses on:

  • early screening
     

  • lifestyle intervention
     

  • regular follow-up
     

According to NITI Aayog, preventive strategies are essential to control India’s diabetes burden.

 

Mental Health and Diabetes in Men

Diabetes can affect mental wellbeing, leading to:

  • stress
     

  • anxiety
     

  • depression
     

Addressing emotional health improves diabetes outcomes.

 

Breaking the Stigma Around Men’s Health

Men often avoid seeking help due to stigma.

Promoting awareness helps:

  • normalise health conversations
     

  • encourage timely medical care
     

  • reduce preventable complications
     

 

Conclusion

Diabetes symptoms in men often develop gradually and may go unnoticed for years. Frequent urination, fatigue, unexplained weight changes and sexual health issues should never be ignored. Early diagnosis and timely management significantly reduce the risk of serious complications and improve long-term health outcomes. Awareness, routine screening and proactive healthcare are essential steps for men to protect their health and wellbeing in an era of rising lifestyle diseases.
