High blood sugar, also known as hyperglycemia, happens when there is too much glucose in your blood. It is a common problem for people with diabetes, but it can also affect anyone due to poor diet, stress, or lack of exercise. Recognising the early warning signs can help you take control before it becomes serious.
Another common symptom is constant tiredness or fatigue. Even though your body has enough sugar, it cannot use it properly for energy. As a result, you may feel weak, sluggish, or sleepy most of the time.
Blurred vision is also an early warning sign. High sugar levels can cause the lens in your eyes to swell, making it hard to see clearly. Some people also experience headaches or dizziness.
Unexplained weight loss can occur even when you are eating normally. This happens because your body starts breaking down fat and muscle for energy when it cannot use glucose effectively.
You might also notice slow-healing wounds or frequent infections, especially in the gums, skin, or urinary tract. High sugar levels weaken your immune system and make it harder for your body to fight bacteria and repair itself.
If you experience any of these symptoms, it is important to check your blood sugar levels and seek medical advice. Early action, such as eating a balanced diet, exercising regularly, and reducing sugar intake, can help prevent complications and keep your blood sugar under control.
