6. Increased appetite
This is a recognized indicator of high blood sugar levels. Excessive hunger or increased appetite is called polyphagia. It’s been described as ‘starving in the land of plenty.’ No matter how much you eat or how frequently you eat, you never feel full. How can it be possible? Polyphagia is not unique to people with high blood sugar levels. It can also occur in people with eating disorders, stress, depression, anxiety, or hyperthyroidism (overactive thyroid gland).
If your blood sugar levels are high, the sugar is not absorbed into your system where the cells convert it to energy. Your body does not absorb the glucose either because it doesn’t produce insulin, or because it has developed insulin resistance. Whichever of these is the cause, the problem remains that your body is prevented from absorbing the glucose. The glucose is then expelled from the body.
Your cells are left with no glucose to help them produce energy. This will immediately make you feel hungry. Your cells are crying out for glucose. So, they’ll send messages to your brain to convince you that you’re hungry. But no matter how much you eat, it won’t help if your body can’t absorb the glucose. And if the glucose isn’t absorbed, your cells still can’t make energy.
In this situation, the best response is exercise. When you exercise, it reduces the glucose levels in the blood. This allows some to be absorbed into the cells to produce energy. In turn, this curbs your appetite. While it might not be the thing you want most at that moment, turning to exercise will help. If you experience an onset of what you believe may be polyphagia, you should see a doctor. It is vital that your blood sugar levels are tested.
