What is Diabetes

Diabetes mellitus, commonly called diabetes, is a chronic (long-term) medical condition that affects how your body turns food into energy.
It happens when your body either does not produce enough insulin or cannot use insulin effectively, leading to high levels of glucose (sugar) in the blood.

When you eat, your body breaks down most of your food into glucose, which is the main source of energy for your cells.
The hormone insulin, produced by the pancreas, helps glucose enter your body’s cells to be used as fuel.

If your body doesn’t make enough insulin or can’t use it properly, glucose stays in your blood instead of moving into cells — causing high blood sugar levels (hyperglycemia).

Types of Diabetes

1. Type 1 Diabetes

  • The body’s immune system attacks and destroys the insulin-producing cells in the pancreas.

  • Usually diagnosed in children or young adults, but can occur at any age.

  • People with Type 1 diabetes need daily insulin injections to survive.


2. Type 2 Diabetes

  • The body doesn’t use insulin effectively (insulin resistance), and over time may stop making enough insulin.

  • Most common type — often related to unhealthy lifestyle, overweight, and genetics.

  • Can often be managed or even delayed with healthy eating, exercise, and medication.


3. Gestational Diabetes

  • Occurs during pregnancy when hormones interfere with insulin function.

  • Usually goes away after childbirth, but increases the mother’s risk of developing Type 2 diabetes later in life.

Common Symptoms

  • Frequent urination (especially at night)

  • Excessive thirst or hunger

  • Unexplained weight loss

  • Fatigue or weakness

  • Blurred vision

  • Slow-healing wounds or frequent infections

  • Tingling or numbness in hands and feet

Many people with Type 2 diabetes don’t notice symptoms early — that’s why regular screening is crucial.


Why Diabetes Matters

If not managed properly, diabetes can lead to serious health problems such as:

  • Heart disease and stroke

  • Kidney failure

  • Vision loss (diabetic retinopathy)

  • Nerve damage (neuropathy)

  • Foot ulcers and amputations

But with early detection, lifestyle changes, and proper treatment, these complications can be prevented or delayed.


Prevention & Management Tips

  • Maintain a healthy weight

  • Eat a balanced diet rich in fiber, fruits, and vegetables

  • Limit sugar and processed foods

  • Exercise at least 30 minutes daily

  • Get regular check-ups and blood sugar tests

  • Manage stress and get enough sleep


In Simple Terms

Diabetes means your body has trouble using sugar the right way.
But with knowledge, awareness, and care — you can live a full, healthy life.
