Blood sugar is a type of sugar that circulates through the bloodstream. It comes from the foods you eat. Additionally, it's responsible for your energy levels.
The level of blood sugar control is directly related to how well your body responds to insulin. Insulin is the hormone that converts the food in your stomach and intestines into energy. The pancreas produces insulin when it detects high blood sugar levels while reducing its production of this hormone when it detects low blood sugar levels.
It also creates glucagon, which can raise your blood sugar levels when they're too low. Your blood sugar should be between 80 to 99mg/dl before eating and 80 to 140mg/dl after eating. People with diabetes have slightly higher numbers, even with medication.
If you control your blood sugar, it can help manage your weight. However, everyone is different. If you have questions about what your glucose levels should be, speak with your doctor.
Additionally, it also helps regulate your energy levels and hunger cravings. If you don't control your blood sugar, it can lead to a host of health problems, including diabetes, heart disease, stroke, and more.
