Everything You Need to Know About Diabetes

Diabetes is a condition that happens when your blood sugar (glucose) is too high. It develops when your pancreas doesn’t make enough insulin or any at all, or when your body isn’t responding to the effects of insulin properly. Insulin is a hormone that regulates blood glucose.

Hyperglycaemia, also called raised blood glucose or raised blood sugar, is a common effect of uncontrolled diabetes and over time leads to serious damage to many of the body's systems, especially the nerves and blood vessels. Over time, having consistently high blood glucose can cause health problems, such as heart disease, nerve damage and eye issues. Diabetes affects people of all ages. Most forms of diabetes are chronic (lifelong), and all forms are manageable with medications and/or lifestyle changes.

Chronic diabetes conditions include type 1 diabetes and type 2 diabetes. Potentially reversible diabetes conditions include prediabetes and gestational diabetes. Prediabetes happens when blood sugar levels are higher than normal. But the blood sugar levels aren't high enough to be called diabetes. And prediabetes can lead to diabetes unless steps are taken to prevent it. Gestational diabetes happens during pregnancy. But it may go away after the baby is born.

Symptoms of Diabetes: What are the symptoms of diabetes?

  • Feeling more thirsty than usual (polydipsia) and dry mouth.
  • Frequent urination.
  • Fatigue, Feeling tired and weak.
  • Blurred vision.
  • Unexplained weight loss.
  • Numbness or tingling in your hands or feet.
  • Getting frequent infections, such as gum, skin and vaginal infections.
  • sores that don’t heal

It’s important to talk to your healthcare provider if you or your child has these symptoms. Over time, diabetes can damage blood vessels in the heart, eyes, kidneys and nerves.People with diabetes have a higher risk of health problems including heart attack, stroke and kidney failure.

Diabetes can cause permanent vision loss by damaging blood vessels in the eyes. Many people with diabetes develop problems with their feet from nerve damage and poor blood flow. This can cause foot ulcers and may lead to amputation.

Types of diabetes:

The most common types of diabetes include type 1, type 2, and gestational diabetes. Less common types of diabetes include monogenic diabetes and cystic fibrosis-related diabetes.

Different kinds of diabetes can occur, and how people manage the condition depends on the type. Not all forms of diabetes stem from a person being overweight or leading an inactive lifestyle. Some are present from childhood.

Type 1 diabetes

Type 1 diabetes (previously known as insulin-dependent, juvenile or childhood-onset) is characterized by deficient insulin production and requires daily administration of insulin. In 2017 there were 9 million people with type 1 diabetes; the majority of them live in high-income countries. Neither its cause nor the means to prevent it are known.

Type 2 diabetes

Type 2 diabetes affects how your body uses sugar (glucose) for energy. It stops the body from using insulin properly, which can lead to high levels of blood sugar if not treated.

Over time, type 2 diabetes can cause serious damage to the body, especially nerves and blood vessels.

Type 2 diabetes is often preventable. Factors that contribute to developing type 2 diabetes include being overweight, not getting enough exercise, and genetics.

Early diagnosis is important to prevent the worst effects of type 2 diabetes. The best way to detect diabetes early is to get regular check-ups and blood tests with a healthcare provider.

Symptoms of type 2 diabetes can be mild. They may take several years to be noticed.? Symptoms may be similar to those of type 1 diabetes but are often less marked. As a result, the disease may be diagnosed several years after onset, after complications have already arisen.

More than 95% of people with diabetes have type 2 diabetes. Type 2 diabetes was formerly called non-insulin dependent, or adult onset. Until recently, this type of diabetes was seen only in adults but it is now also occurring increasingly frequently in children.

Gestational diabetes

Gestational diabetes is hyperglycaemia with blood glucose values above normal but below those diagnostic of diabetes. Gestational diabetes occurs during pregnancy.

Women with gestational diabetes are at an increased risk of complications during pregnancy and at delivery. These women and possibly their children are also at increased risk of type 2 diabetes in the future.

Gestational diabetes is diagnosed through prenatal screening, rather than through reported symptoms.

Diabetes risk factors

Certain factors increase your risk for diabetes.

Type 1 diabetes

You’re more likely to get type 1 diabetes if you’re a child or teenager, you have a parent or sibling with the condition, or you carry certain genes that are linked to the disease.

Type 2 diabetes

Your risk for type 2 diabetes increases if you:

  • are overweight
  • are age 45 or older
  • have a parent or sibling with the condition
  • aren’t physically active
  • have had gestational diabetes
  • have prediabetes
  • have high blood pressure, high cholesterol, or high triglycerides

Type 2 diabetes also disproportionately affects certain racial and ethnic populations.

Adults who have African American, Hispanic or Latino American, or Asian American ancestry are more likely to be diagnosed with type 2 diabetes than white adults, according to 2016 research. They’re also more likely to experience decreased quality of care and increased barriers to self-management.

Type 1.5 diabetes

Type 1.5 diabetes is found in adults over 30 and is often mistaken for type 2, but people with this condition are not necessarily overweight, and oral medications and lifestyle changes have no effect.

Gestational diabetes

Your risk for gestational diabetes increases if you:

  • Are overweight
  • Are over age 25
  • Had gestational diabetes during a past pregnancy
  • Have given birth to a baby weighing more than 9 pounds
  • Have a family history of type 2 diabetes
  • Have polycystic ovary syndrome (PCOS)

Diabetes prevention: How can I prevent diabetes?

You can’t prevent autoimmune and genetic forms of diabetes. But there are some steps you can take to lower your risk for developing prediabetes, Type 2 diabetes and gestational diabetes, including:

  • Eat a healthy diet, such as the Mediterranean diet.
  • Get physically active. Aim for 30 minutes a day at least five days a week.
  • Work to achieve a weight that’s healthy for you.
  • Manage your stress.
  • Limit carbonated drinks/ alcohol intake.
  • Get adequate sleep (typically 7 to 9 hours) and seek treatment for sleep disorders.
  • Quit smoking.
  • Take medications as directed by your healthcare provider to manage existing risk factors for heart disease.


It’s important to note that there are some diabetes risk factors you can’t change, such as your genetics/family history, age and race. Know that Type 2 diabetes is a complex condition that involves many contributing factors.

Sometimes drugs are an option. Oral diabetes drugs such as metformin (Glumetza, Fortamet, others) may lower the risk of type 2 diabetes. But healthy lifestyle choices are important. If you have prediabetes, have your blood sugar checked at least once a year to make sure you haven't developed type 2 diabetes.

Being diagnosed with diabetes is a life-changing event, but it doesn’t mean you can’t live a happy and healthy life. Managing diabetes involves consistent care and diligence. While it’ll likely be very overwhelming at first, over time you’ll get a better grasp on managing the condition and being in tune with your body.

Be sure to see your healthcare provider(s) regularly. Managing diabetes involves a team effort — you’ll want medical professionals, friends and family on your side. Don’t be afraid to reach out to them if you need help.
