There’s no sugar-coating diabetes

Nov 23, 2025

You probably know someone with diabetes, but what might surprise you is that the condition is the number one cause of death in women, and second overall. That’s because too many South Africans are diagnosed late or not at all.

The good news? With treatment and healthy lifestyle management, diabetics can live long, happy lives. Understanding the condition is the first step.

Our bodies are powered by glucose, a sugar that comes from food. To use it, we need a hormone made in the pancreas – insulin. Think of it like ordering a meal: the delivery driver must bring it to you, otherwise it just sits at the shop. Insulin is the “driver” carrying glucose to our cells. If insulin isn’t produced or it can’t do its job, we can’t function.

Without insulin doing its job, glucose piles up in the blood (high blood sugar) and starts damaging blood vessels, nerves and organs.

Types of diabetes

Type 1

In this type, the immune system attacks insulin-producing cells, so the pancreas can’t make insulin – there’s no delivery driver. It usually starts in childhood or adolescence and is triggered by a combination of genetics and the environment, like a virus.

Type 1 is irreversible and life-threatening without insulin and strict lifestyle management.

Type 2

The most common type, in which there’s either not enough insulin or your body resists it – the driver is there but the door is stuck, so glucose builds up in the blood.

This type develops more slowly and usually occurs later in life. Risks include family history, poor diet, chronic stress, insufficient exercise and excess weight. Treatment requires lifestyle changes and medication. If caught early, Type 2 diabetes may be reversible.

Gestational (pregnancy)

Around 1 in 20 pregnancies leads to temporary insulin resistance, which could cause premature birth, large babies and other complications.

Gestational diabetes usually resolves after birth, but both mother and child now have a higher lifetime risk of Type 2.

Type 3C

Sometimes ill health, like cystic fibrosis, cancer or damage to the pancreas, can decrease or stop insulin production. Unlike Type 1, it’s not autoimmune, but it is usually permanent and insulin-dependent.

Know the signs

Warning signs include:

Increased thirst and urination
Extreme hunger
Rapid, unexplained weight loss (mainly in Type 1)
Blurry vision
Slow-healing wounds
Poor resistance to infections

But in the early stages, you might not notice the signs or put two and two together. Get your blood sugar level checked every year, so if you’re at risk for diabetes, you can put the brakes on it.

Myth-busting

Only obese people get diabetes. While being overweight increases your risk, anyone, from any walk of life and any size can develop it.
Only older people get Type 2 diabetes. There’s an alarming rise in young people developing Type 2, with children as young as three being diagnosed.
Diabetics can’t eat sugar. In moderation and as part of a balanced diet, sweet treats can be enjoyed. Don’t put off testing because you don’t want to give up sweet things.

5 surprising facts about ADHD

Think attention-deficit/hyperactivity disorder (ADHD) is shorthand for someone who can’t sit still and focus?
In fact, it’s not an inability to focus, it’s about regulating attention. Many people with ADHD describe becoming intensely focused on some tasks – known as ‘hyperfocus’ – while struggling to start or complete things that don’t grab their attention.

When children get cancer

No one wants to hear that a child has cancer. Fortunately, childhood cancer is rare and accounts for less than 1% of all cancers.
The danger is that many childhood cancers progress very quickly, so it’s important for caregivers to be aware of warning signs – and seek help.
With September being Childhood Cancer Awareness Month, now is the time to learn more.

When breastfeeding does not work for you

Breastfeeding is often portrayed as one of the most natural parts of motherhood – an instinctive, nurturing interaction between mother and child. But what if that image of effortless nursing doesn’t reflect your reality?
You’re not alone. In fact, 60-80% of new moms say they have difficulty breastfeeding. What’s more, in South Africa, the tally for infants under six months that are exclusively breastfed is less than one in three.

Why you should start building bone today

Over the years, your bones gradually break down – and for women after menopause, it’s a particularly big problem.
Your bones may seem solid, but they’re actually living tissue constantly renewing itself – like a well-maintained building. New parts replace old ones all the time, but if the building loses more bricks at a rate than they can be replaced, the structure becomes weaker.

South Africa’s colder months can bring a mixed bag of winter woes. More time indoors, closer contact with others, indoor heating – the perfect conditions for colds and flu. Shorter days also affect vitamin D levels and mood. It’s not surprising that many of us end up feeling less than sunny.
