What are normal blood sugar levels?
The
body tightly regulates blood sugar levels to ensure they stay within a narrow
range. When you consume carbohydrates (found in foods like bread, rice, fruits,
and vegetables), they are broken down into glucose during digestion. The
glucose is then absorbed into the bloodstream, causing blood sugar levels to
rise.
In
response to rising blood sugar, the pancreas releases a hormone called insulin.
Insulin enables glucose to enter cells, where it can be used for energy
production or stored for later use. As a result, insulin helps lower blood
sugar levels.
Conversely,
when blood sugar levels are too low, the pancreas releases another hormone
called glucagon. Glucagon signals the liver to convert stored glycogen into
glucose, thereby raising blood sugar levels.
Maintaining
a balanced blood sugar level is crucial for the body's proper functioning.
Prolonged high blood sugar levels (hyperglycemia) can be a sign of diabetes or
other health conditions, while consistently low blood sugar levels
(hypoglycemia) can also be a concern.
People
with diabetes often monitor their blood sugar levels regularly, typically using
a glucose meter. They may need to take medications, such as insulin injections
or oral hypoglycemic drugs, to help manage their blood sugar levels
effectively. Lifestyle factors like diet, physical activity, and stress
management also play a significant role in maintaining optimal blood sugar
levels.
