The liver plays a crucial role in regulating blood sugar levels in the body.
Between meals:
- When blood sugar levels drop between meals, the liver releases stored glucose in the form of glycogen to help maintain a stable blood sugar level.
- The liver also produces glucose through a process called gluconeogenesis, where it converts non-carbohydrate sources such as amino acids and glycerol into glucose. This helps to ensure that the body has a constant supply of glucose for energy.
After meals:
- After a meal, when blood sugar levels rise, the liver helps to regulate this by storing excess glucose as glycogen for later use.
- The liver also plays a role in removing excess glucose from the bloodstream by converting it into fatty acids for storage as fat.
- Additionally, the liver produces and releases insulin-like growth factor 1 (IGF-1) in response to insulin, which helps to regulate blood sugar levels and promote cell growth and repair.
Overall, the liver acts as a central regulator of blood sugar levels in the body, ensuring that there is a constant supply of glucose for energy production and maintaining a stable blood sugar level throughout the day.

Regulation of Blood Sugar Level by the Liver
Between Meals:
- When blood sugar levels drop (fasting state), the liver releases glucose into the bloodstream.
- It does this through a process called gluconeogenesis, in which it converts non-carbohydrate substances, such as amino acids and fatty acids, into glucose.
- This process is stimulated by hormones, such as glucagon and epinephrine.
After Meals:
- When blood sugar levels rise after a meal, the liver takes up excess glucose and stores it as glycogen through a process called glycogenesis.
- Glycogen is a complex carbohydrate that serves as a reserve of glucose.
- Insulin, a hormone released by the pancreas, stimulates glycogenesis.
Specific Mechanisms Involved:
In the fasting state:
- Gluconeogenesis occurs in hepatocytes (liver cells) via enzymatic reactions that convert amino acids and fatty acids into glucose.
- Glycogenolysis, the breakdown of glycogen into glucose, is suppressed by low insulin levels.
After meals:
- Glycogenesis is activated by high insulin levels, promoting the formation of glycogen in the liver.
- Gluconeogenesis is inhibited by high insulin levels, preventing excessive glucose production.
- The liver also upregulates enzymes involved in glucose uptake, further aiding in the removal of glucose from the bloodstream.
Overall, the liver plays a crucial role in maintaining blood sugar homeostasis by:
- Releasing glucose during fasting to prevent hypoglycemia (low blood sugar).
- Storing excess glucose as glycogen after meals to prevent hyperglycemia (high blood sugar).
- Regulating the rate of glucose release and uptake to stabilize blood sugar levels.
