Facing Diabetes? Your Doc Explains What’s Next

By Dr. Priya Sammani ( MBBS, DFM )

I remember a patient, let’s call him John, who came in a while back. He was just feeling… off. More tired than usual, always thirsty, and making extra trips to the bathroom, even at night. “Doc,” he said, “I just don’t feel like myself anymore.” Those subtle changes, the ones you might brush off? Sometimes they’re our body’s way of whispering that something needs a closer look. For John, it turned out to be diabetes.

Hearing that word can be a bit of a shock, I know. But understanding what’s going on is the first step, and honestly, we’ve got good ways to manage it.

So, What Exactly Is Diabetes?

At its heart, diabetes is a condition where your blood sugar, or glucose, is too high. Think of glucose as the fuel your body runs on. It mainly comes from the carbohydrates in your food and drinks. Now, for that fuel to get into your cells and do its job, it needs a key. That key is a hormone called insulin, which your pancreas makes.

If your pancreas doesn’t make enough insulin, or if your body’s cells stop responding to insulin properly (we call this insulin resistance), that glucose can’t get into your cells. Instead, it builds up in your bloodstream. Over time, this high blood sugar can cause various health problems.

It’s a lifelong condition for most, but totally manageable. And there’s another condition called diabetes insipidus – sounds similar, right? But it’s very different, mainly causing thirst and frequent urination without the blood sugar issues of diabetes mellitus (the one we’re talking about).

The Different Faces of Diabetes

Not all diabetes is the same. Here are the main types we see:

  • Type 2 Diabetes: This is the most common one. Your body either doesn’t make enough insulin, or your cells ignore the insulin (that insulin resistance I mentioned). It often shows up in adults, but we’re seeing it more in younger folks too.
  • Prediabetes: Think of this as a warning sign. Your blood sugar is higher than normal, but not quite in the Type 2 diabetes range yet. It’s a crucial time to make some lifestyle changes.
  • Type 1 Diabetes: This is an autoimmune condition. For reasons we don’t fully understand, the body’s immune system mistakenly attacks and destroys the insulin-making cells in the pancreas. It often starts in childhood or young adulthood, but can happen at any age. Only about 10% of people with diabetes have Type 1.
  • Gestational Diabetes: Some women develop this during pregnancy. It usually goes away after the baby is born, but it does mean there’s a higher chance of developing Type 2 diabetes later on.

There are other, less common types too, like LADA (Latent Autoimmune Diabetes in Adults), MODY (Maturity-Onset Diabetes of the Young), and diabetes caused by damage to the pancreas (Type 3c diabetes). Each has its own specific features, but the core issue remains problems with insulin and blood sugar.

It’s pretty common, actually. Millions of people are living with diabetes, and many more have prediabetes and don’t even know it.

What Signs Might You Notice?

Sometimes, especially with Type 2 diabetes or prediabetes, the signs are so subtle they creep up on you. Or you might not have any symptoms at all. But here are some common things to watch out for:

  • Feeling incredibly thirsty (the medical term is polydipsia) and having a dry mouth.
  • Needing to pee a lot more often, especially at night.
  • Feeling really tired all the time.
  • Blurred vision that comes and goes.
  • Losing weight without trying.
  • Numbness or tingling in your hands or feet.
  • Sores or cuts that are slow to heal.
  • Getting frequent skin infections or vaginal yeast infections.

With Type 1 diabetes, symptoms can come on quite quickly, sometimes over just a few weeks. You might also notice vomiting, stomach pains, or fruity-smelling breath, which can be signs of a serious condition called diabetes-related ketoacidosis (DKA). DKA is an emergency, so if you see these, get help right away.

With prediabetes, you might notice darkened skin in areas like your neck or armpits – we call this acanthosis nigricans.

If any of this sounds familiar for you or your child, it’s definitely worth a chat with us.

What’s Behind High Blood Sugar?

The “why” depends on the type of diabetes:

  • Insulin resistance is the main culprit in Type 2 diabetes. Things like being overweight, not getting enough exercise, your diet, hormonal changes, and even your genes can play a role.
  • Autoimmune reactions cause Type 1 diabetes and LADA, where the body attacks its own pancreas.
  • Hormonal changes during pregnancy can lead to gestational diabetes if the pancreas can’t keep up with the increased need for insulin.
  • Damage to the pancreas from illness, surgery, or conditions like pancreatitis can also lead to diabetes.
  • Sometimes, genetic mutations are responsible, as in MODY or neonatal diabetes.
  • Even some medications, like corticosteroids, can raise blood sugar if used long-term.

Why We Need to Manage Diabetes: Potential Complications

Keeping blood sugar levels in a healthy range is so important because consistently high levels can, over time, lead to serious problems.

Sudden (Acute) Complications:

These can be scary and need quick attention:

  • Diabetes-related Ketoacidosis (DKA): Mainly in Type 1. Your body, starved for glucose, breaks down fat too fast, making your blood acidic. It’s life-threatening.
  • Hyperosmolar Hyperglycemic State (HHS): Mostly in Type 2. Extremely high blood sugar leads to severe dehydration. Also needs immediate medical help.
  • Severe Low Blood Sugar (Hypoglycemia): If blood sugar drops too low, especially with insulin use, it can cause confusion, clumsiness, and even seizures.

Long-Term Complications:

These develop gradually if blood sugar isn’t well managed:

  • Heart and blood vessel disease: This is a big one. Think coronary artery disease, heart attack, and stroke.
  • Nerve damage (neuropathy): This can cause pain, tingling, or numbness, often in the feet and hands.
  • Kidney damage (nephropathy): Can lead to kidney failure.
  • Eye damage (retinopathy): Can affect vision and even lead to blindness.
  • Foot problems: Poor circulation and nerve damage can lead to serious infections and, sometimes, amputations.
  • Skin infections, sexual dysfunction, digestive issues (gastroparesis), and hearing loss.
  • Even your oral health can be affected.

Living with a chronic condition can also take a toll on your mental health. It’s not uncommon for people with diabetes to experience depression, so support is key.

How Do We Figure This Out? Diagnosis

Diagnosing diabetes usually involves simple blood tests. We’re looking at your glucose levels.

  • Fasting Blood Glucose Test: You’ll fast (no food or drink, except water) for at least 8 hours, then we’ll check your blood sugar. This gives us a baseline.
  • Random Blood Glucose Test: We can do this anytime, no fasting needed.
  • A1c Test (or HbA1c): This is a fantastic test. It gives us an average picture of your blood sugar levels over the past 2-3 months.

For pregnant women, we do an oral glucose tolerance test to check for gestational diabetes, usually between 24 and 28 weeks of pregnancy.

Here’s generally what the numbers mean (though slight variations can occur, and we often use more than one test):

  • A1c:
  • Normal: Below 5.7%
  • Prediabetes: 5.7% to 6.4%
  • Diabetes: 6.5% or higher
  • Fasting Plasma Glucose (FPG):
  • Normal: 99 mg/dL or below
  • Prediabetes: 100 to 125 mg/dL
  • Diabetes: 126 mg/dL or higher
  • Random Plasma Glucose (RPG):
  • Diabetes: 200 mg/dL or higher (with symptoms of high blood sugar)

Taking Control: Managing Diabetes

Okay, so if it is diabetes, what do we do? Managing it is a team effort – you, me, and sometimes other specialists like dietitians or endocrinologists (doctors who specialize in hormone problems). The plan is always personalized, because everyone’s different.

Here are the main pillars of diabetes management:

  1. Monitoring Your Blood Sugar: This is so important. It tells us how well your treatment is working. You might use a glucose meter with a finger prick, or a continuous glucose monitor (CGM). We’ll figure out a target range that’s right for you.
  2. Medications (If Needed):
  • Oral Medications: Many people with Type 2 diabetes or prediabetes benefit from pills that help their body use insulin better or make less glucose. Metformin is a very common one.
  • Insulin: Everyone with Type 1 diabetes needs to take insulin to live. Some people with Type 2 diabetes also need it. There are different types of insulin and ways to take it – injections, insulin pens, insulin pumps, or even inhaled insulin.
  1. Diet: What you eat has a huge impact on blood sugar. We’ll talk about healthy eating, meal planning, and if you’re on insulin, counting carbohydrates. It’s not about never eating your favorite foods, but about balance and understanding how food affects you.
  2. Exercise: Regular physical activity helps your body use insulin better and can lower blood sugar. Even a brisk walk most days makes a difference!

We also need to keep an eye on your blood pressure, cholesterol, and weight, as these are all linked to heart health, which is especially important when you have diabetes.

Can We Prevent Diabetes?

You can’t prevent Type 1 diabetes because it’s autoimmune. And some genetic forms are just that – genetic. But for prediabetes, Type 2 diabetes, and gestational diabetes, there’s a lot you can do to lower your risk:

  • Eat a balanced, healthy diet (think lots of fruits, veggies, whole grains, lean protein).
  • Get regular exercise – aim for about 30 minutes most days of the week.
  • Work towards a healthy weight for you.
  • Find ways to manage stress.
  • If you drink alcohol, do so in moderation.
  • Try to get enough sleep.
  • If you smoke, quitting is one of the best things you can do for your overall health.

Remember, some risk factors like your family history, age, or race can’t be changed. It’s not about blame; it’s about doing what we can.

Living Well with Diabetes: Key Takeaways

  • Diabetes means your blood sugar is too high, usually due to issues with insulin.
  • The main types are Type 1, Type 2, and gestational diabetes, each with different causes.
  • Common symptoms include increased thirst, frequent urination, fatigue, and blurred vision, but sometimes there are no symptoms.
  • Management involves monitoring blood sugar, healthy eating, exercise, and often medication or insulin.
  • While diabetes is serious, it is manageable, and you can live a long, healthy life. Keeping your A1c levels below 7% can significantly reduce the risk of complications.
  • Don’t hesitate to reach out if you have symptoms or concerns about diabetes.
