Fatigue
Severe fatigue or burnout occurs when the body cannot use glucose from food for energy. When the body lacks insulin, glucose is not taken into cells but instead stored in the blood. Due to improper use of glucose, the body does not have enough energy, causing burnout and sleepiness.
Excessive thirst and frequent urination
Feeling unable to quench your thirst despite drinking a lot of water is one of the common symptoms of high blood sugar. When blood sugar levels increase, excess glucose is excreted in the urine. Glucose tends to attract water into the urine, causing the body to lose more fluid. Excessive urination is often accompanied by high thirst. This condition is called polyuria. Frequent thirst can increase the risk of dehydration, leading to nausea, dizziness, headaches, and fainting.
Unexplained weight loss
This is a sign of many diseases, including high blood sugar. Uncontrolled blood sugar levels make it impossible for glucose to be used for energy. The body takes energy from muscles and fat to maintain activity, affecting weight.
Frequent infections and skin problems
High blood sugar can weaken the immune system, bacteria tend to grow more strongly in sugary environments, thereby increasing the risk of recurring infections. People with hyperglycaemia are at higher risk of respiratory and urinary tract infections. High blood sugar causes a number of changes in the skin, including dry or itchy skin, frequent skin infections, and slow wound healing.
Numbness or tingling in the hands and feet, blurred vision
These symptoms can occur when there is poor blood circulation due to glucose accumulation. This is a more common symptom in people with long-term diabetes. High blood sugar can increase fluid levels in the eyes, making the lens unable to change shape, leading to blurred vision, swelling of tissue in the eyes, affecting vision.
