Diabetes alert: Early signs to watch for (before it’s too late)

Type 2 diabetes is one of the most feared diseases in the world, with nearly 600 million victims of it. It’s a chronic disease where the body either doesn't produce enough insulin, a hormone that helps glucose enter cells, or it doesn't use insulin effectively (insulin resistance). This leads to high blood sugar levels, as too much glucose stays in the blood and not enough reaches the cells for energy.

As of 2025, an estimated 589 million adults are living with diabetes worldwide, representing 1 in 9 adults aged 20-79 years, according to the 11th edition of the IDF Diabetes Atlas. What’s more worrisome? This number is projected to rise to 853 million by 2050.

What makes diabetes dangerous? It often develops silently, with symptoms so mild that they go unnoticed until complications arise. That’s why early detection is crucial to prevent serious health issues such as heart disease, kidney failure, and nerve damage.

Also, as the condition manifests in various ways, being aware of these signs can help individuals seek medical advice promptly. While some symptoms are common across both Type 1 and Type 2 diabetes, others may be more specific to each type.

Recognizing the red flags before they advance to a lethal stage can lead to timely intervention, lifestyle changes, and better management of the condition.

One of the earliest signs of diabetes is increased urination, known as polyuria. Elevated blood sugar levels cause the kidneys to filter out excess glucose, leading to more frequent urination, especially during the night. This condition often results in dehydration, prompting the body to signal increased thirst, a symptom termed polydipsia. If you find yourself drinking more fluids than usual without a clear reason, it could be an indication of high blood sugar levels.

Despite eating normally or even more than usual, individuals with diabetes may experience unexplained weight loss. This occurs because the body starts breaking down muscle and fat for energy due to the inability to utilize glucose effectively. If you're losing weight without trying, it's essential to consult a healthcare provider to rule out diabetes or other underlying conditions.

Feeling unusually tired or weak can be a sign of diabetes. When the body cannot use glucose properly, it lacks the energy needed for daily activities. This persistent fatigue, even after adequate rest, can affect both physical and mental well-being, making it difficult to perform routine tasks.

High blood sugar levels can lead to fluid being pulled from tissues, including the lenses of the eyes. This can affect the ability to focus, resulting in blurred vision. If you notice changes in your eyesight, it's important to get your blood sugar levels checked, as prolonged high blood sugar can lead to more serious eye problems.

Diabetes can impair the body's ability to heal and fight infections. High blood sugar levels can affect circulation and the immune system, leading to slow-healing wounds and increased susceptibility to infections, particularly of the skin, gums, and urinary tract.

Over time, high blood sugar can damage nerves, a condition known as diabetic neuropathy. This damage often leads to tingling, pain, or numbness in the hands or feet. If you experience these sensations, it's crucial to seek medical attention, as nerve damage can lead to more severe complications if left untreated.

Dry skin and itching can be signs of diabetes. High blood sugar levels can lead to dehydration, causing the skin to become dry and itchy. Additionally, poor circulation associated with diabetes can contribute to these skin issues. Keeping the skin moisturized and maintaining good blood sugar control can help alleviate these symptoms.

Known as polyphagia, increased hunger can occur when the body doesn't get enough energy from glucose. Despite eating more, individuals may still feel hungry, as the cells are not receiving the energy they need. This symptom, combined with other signs, should prompt a discussion with a healthcare provider.

Certain factors increase the risk of developing diabetes. These include:

Family History: Having a close relative with diabetes increases your risk.

Age: Individuals over 45 are at higher risk.

Obesity: Excess weight, especially around the abdomen, is a significant risk factor.

Physical Inactivity: Lack of regular physical activity can lead to weight gain and increased blood sugar levels.

Unhealthy Diet: Diets high in processed foods and low in fiber can contribute to the development of diabetes.

If you experience any of the aforementioned symptoms, it's important to consult a healthcare provider. Early detection and timely intervention can prevent or delay the onset of complications associated with the condition.
