Diabetes and Blood Sugar Control

Diabetes, a chronic metabolic condition, manifests as a disruption in the body’s ability to regulate blood sugar levels effectively. This imbalance primarily stems from either insufficient insulin production or the body’s resistance to the effects of insulin. Insulin, a hormone produced by the pancreas, facilitates the absorption of glucose (sugar) from the bloodstream into cells, where it’s used as an energy source.

Type 1 diabetes occurs when the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas, leading to a lack of insulin production. On the other hand, Type 2 diabetes, the more prevalent form, results from a combination of insulin resistance and inadequate insulin secretion.

Maintaining optimal blood sugar levels is pivotal in diabetes management to avert short-term complications such as hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar) and to mitigate the long-term risks associated with diabetes, including heart disease, kidney damage, nerve impairment, and vision problems.

Multi-faceted approach
