Dr Ravi Gupta captioned, “Your blood sugar can stay high before you feel like anything is wrong. Constant thirst, frequent hunger, blurry vision, slow-healing cuts, or repeated infections can be clues. But the most important sign? Sometimes there is no sign at all. That’s why knowing your numbers matters. Dr Gupta highlighted that when blood glucose rises high enough, your kidneys try to remove more glucose through urine, and that pulls water with it. So you may notice that you feel constantly thirsty, which leads to more urination. So you may notice that you get hungry soon even after eating. Your cravings also tend to become stronger, and you feel low energy.
High blood sugar can mean glucose is in your bloodstream, but your cells aren’t using it efficiently, according to Dr Gupta.
Chronically high blood sugar can affect blood vessels, circulation, and immune function, which can make wound healing slower. If cuts and wounds are taking normal than expected to heal on its own, it’s time you get your blood sugar level tested. Dr Gupta highlighted that high glucose can temporarily change fluid levels inside the eye that can make vision fluctuate. If your eyesight suddenly changes, don’t assume it’s just screen time. Your body might be indicating high blood sugar. High blood glucose can make some infections more likely, especially urinary infections, fungal infections, and skin infections. Dr Gupta highlights that more abdominal fat is strongly linked with insulin resistance and, for South Asians, metabolic risk can appear at a lower BMI than many people expect. Your weight might remain the same, but your waist size starts to increase. The mirror may miss what your metabolism doesn’t.
