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.

Understanding Diabetes Type 2 Symptoms: A Simple Guide

Diabetes is a common health condition that affects millions of people around the world. Among its different types, Type 2 diabetes is the most widespread. It often develops slowly and can go unnoticed for years. That's why it’s important to understand the symptoms of diabetes type 2, so you can take timely action and protect your health.

In this blog, we will explain what Type 2 diabetes is, the signs to watch out for, and when to see a doctor.

 

What is Type 2 Diabetes?

Type 2 diabetes is a chronic condition where your body either doesn't produce enough insulin or can’t use it properly. Insulin is a hormone that helps your body control blood sugar (glucose) levels. Without enough insulin, sugar builds up in your bloodstream instead of being used for energy.

This buildup of sugar can damage your organs over time, including your heart, kidneys, eyes, and nerves. That’s why early detection and treatment are very important.

 

Who is at Risk?

Type 2 diabetes can affect anyone, but some people are more likely to get it. You may have a higher risk if you:

  • Are overweight or obese
     

  • Have a family history of diabetes
     

  • Are over the age of 45
     

  • Live a sedentary (inactive) lifestyle
     

  • Have high blood pressure or cholesterol
     

  • Had gestational diabetes during pregnancy
     

  • Belong to certain ethnic groups (such as South Asian, African-Caribbean, or Hispanic)
     

Knowing your risk factors can help you stay alert and get tested early.

 

Common Diabetes Type 2 Symptoms

The symptoms of Type 2 diabetes often develop slowly, and many people may not notice them right away. Some people don’t experience any symptoms at all until complications arise. That’s why it’s sometimes called a "silent" disease.

Here are the most common diabetes 2 symptoms to look out for:

1. Frequent Urination

If you find yourself needing to urinate more often than usual, especially at night, it could be a sign of high blood sugar. Your body tries to get rid of the excess glucose through urine.

2. Excessive Thirst

Frequent urination can make you lose a lot of water, leading to dehydration. This makes you feel unusually thirsty all the time.

3. Increased Hunger

Despite eating enough, people with Type 2 diabetes may feel hungry more often. This is because the body isn’t using the glucose in the blood properly for energy.

4. Fatigue and Tiredness

When your body can’t use sugar for fuel, it leads to low energy levels. This can make you feel tired, weak, or sluggish even after a good night's sleep.

5. Blurred Vision

High blood sugar levels can affect the tiny blood vessels in your eyes, leading to blurry vision. If untreated, it can even cause permanent eye damage.

6. Slow Healing Wounds

Cuts, bruises, or infections may take longer to heal if your blood sugar is high. This happens because diabetes affects blood circulation and the immune system.

7. Tingling or Numbness

Many people with diabetes experience tingling, pain, or numbness in their hands or feet. This is known as diabetic neuropathy and is caused by nerve damage due to high blood sugar.

8. Unexplained Weight Loss

If you're losing weight without trying, it could be a warning sign. When your body can’t use sugar properly, it starts burning fat and muscle for energy.

9. Skin Problems

Dark patches on the skin, especially around the neck or armpits (a condition called acanthosis nigricans), can be an early sign of insulin resistance.

 

When Should You See a Doctor?

If you notice any of the above symptoms, it’s important to see a healthcare provider for a simple blood sugar test. Early diagnosis can help you manage the condition better and prevent serious complications.

Even if you feel fine, it's a good idea to get regular health check-ups, especially if you’re at higher risk.

 

How is Type 2 Diabetes Diagnosed?

Doctors use the following tests to diagnose Type 2 diabetes:

  • Fasting blood sugar test: Measures blood sugar after not eating for 8 hours
     

  • HbA1c test: Shows your average blood sugar levels over the last 2-3 months
     

  • Oral glucose tolerance test: Measures how your body handles sugar after drinking a sweet drink
     

  • Random blood sugar test: Can be done at any time of the day
     

Your doctor may repeat tests or use more than one type to confirm the diagnosis.

 

Can Type 2 Diabetes be Managed?

Yes! Type 2 diabetes can be managed with lifestyle changes, medications, and regular monitoring. Some people are even able to reverse it through weight loss and healthy habits.

Here’s how you can manage it:

  • Eat a balanced diet: Include whole grains, vegetables, lean proteins, and fruits
     

  • Exercise regularly: Aim for at least 30 minutes of activity most days of the week
     

  • Lose excess weight: Even a small amount of weight loss can improve your blood sugar
     

  • Take medications if needed: Your doctor may prescribe tablets or insulin
     

  • Monitor blood sugar: Keep track of your glucose levels as advised by your doctor
     

  • Avoid smoking and alcohol: These can worsen diabetes and its complications
     

 

Final Thoughts

Type 2 diabetes is a serious condition, but it can be controlled and even reversed with the right steps. Understanding the early warning signs and diabetes 2 symptoms can make a big difference in your health journey.

If you or someone you love is experiencing these symptoms, don’t wait—talk to a doctor today and get tested. Early action can help you lead a healthier, longer life.
