Do you or your loved ones suffer from excessive thirst, frequent urination, or numbness in the feet? These might seem like minor, daily inconveniences, but they are actually your body’s way of communicating with you. Way too many people wait for a doctor’s visit to take action, yet millions are already living with prediabetes without even knowing it. Understanding these signs is crucial for taking control of your own health.
Diabetes is a condition in which the body’s blood sugar — also known as glucose — is too high. This happens when the pancreas does not make enough insulin, or does not make insulin at all, or when your body is unable to respond to insulin normally. Diabetes can happen at all ages. Most types of diabetes are chronic, meaning they are not curable but can be reversed with diet and exercise.
Types of Diabetes
There are three main types of diabetes. In Type 2 diabetes — the most common type — the body does not make enough insulin and/or the body’s cells do not respond normally to it, which is known as insulin resistance. This type is usually found in adults. Type 1 diabetes is an autoimmune disease in which the body’s own immune system destroys the insulin-producing cells in the pancreas. It usually occurs in children and is not preventable since it is genetic. Gestational diabetes develops in some pregnant women and is usually resolved after delivery — however, these women have a greater risk of developing Type 2 diabetes later in life.
Health Complications of Diabetes
Glucose is mainly obtained from carbohydrates in what we eat and drink. It is your body’s major source of energy. The blood carries glucose to all of our cells to be used for energy. Insulin can be thought of as a “key” that unlocks our cells. Without it, glucose just remains in the bloodstream. Over time, if glucose builds up, the result is high blood sugar — which can lead to serious health issues including heart problems, nerve damage, and eye and kidney problems.
Heart Disease and Stroke
When blood sugar stays high for too long, it damages the blood vessels and nerves that help your heart function normally, which can eventually lead to heart disease and stroke. Risk factors that compound with diabetes include smoking, high blood pressure, abnormal cholesterol levels, obesity, chronic kidney disease, and a family history of heart disease.
Nerve Damage
Long-term high blood sugar can damage your nerves — a condition called neuropathy. This can cause tingling, pain, and even complete numbness in your feet. Diabetes can also reduce blood flow to your feet, meaning even a small cut or infection takes much longer to heal. In severe cases, some people require amputation to prevent the spread of infection. Neuropathy can also affect internal organs, causing issues with heart rate, blood pressure, and the digestive system.
Eye and Kidney Problems
Long-term diabetes can severely impact your eyes, leading to issues ranging from minor vision loss to total blindness. Diabetic eye disease presents with symptoms such as blurry vision, poor colour vision, and flashes of light. Diabetes is also the leading cause of kidney disease. Your kidneys are your body’s natural filtration system — they clean your blood by removing toxins and excess water. When damaged, these toxins build up, leading to further health complications. Importantly, this damage develops gradually over several years, not overnight.
How Can Diabetes be Prevented and Managed?
Finding out you are at risk — or being diagnosed — can be a wake-up call. While you cannot change your DNA or medical history, knowing your risk factors allows you to make proactive choices today. There are three key lifestyle changes that can reduce your chances of developing Type 2 diabetes, or help manage it if already diagnosed.
Losing Weight
One of the most effective ways to prevent or manage diabetes is through sustainable weight loss. You don’t need a complete body transformation. Losing just 5–7% of your body weight can make a significant difference. For a person weighing 90 kg, that means a manageable goal of losing just 5 to 6 kg.
Physical Activity
Aim for at least 30 minutes of physical activity five days a week. Whether it’s a brisk walk, a swim, or a dance class, raising your heart rate is highly beneficial for blood sugar control. If you’re not used to being active, start small and build up gradually.
Balanced Diet
The most fundamental way to lower your risk is to eat well. Start by reducing portion sizes to lower your daily calorie intake. Cut back on hidden calories by choosing lower-fat options and swapping sugary sodas or juices for water. These small, daily adjustments add up to meaningful weight loss over time.
Your HbA1c is your three-month blood sugar average. When you improve insulin sensitivity, HbA1c levels can reverse from the prediabetes range back to normal. By controlling these levels in the early or middle stages of insulin resistance, you can often reverse negative effects through the lifestyle changes described above.
Your Health is in Your Hands
Diabetes may be a complex conversation your body is having with you, but the response is simple: small changes lead to significant results. Whether you have been diagnosed or are looking to lower your HbA1c back to a healthy range, the most important principle is consistency. By focusing on sustainable weight loss, regular movement, and a healthier diet, you can reset your insulin sensitivity and protect your heart, kidneys, and vision in the long term.
