Diabetes is a chronic disease that affects approximately 589 million people worldwide. Type 2 diabetes is one of its main forms (~90%) and manifests as hyperglycemia due to the resistance of myocytes and adipocytes to insulin. These are unable to capture and use blood glucose. In the long term, T2D can lead to a reduced production of insulin by beta cells, leading to more complex complications. Metformin is the first-line treatment for this condition. However, it may not always be effective for regulating blood glucose levels. Some factors, such as genetics, may influence the drug efficacy for this disease. The aim of this review is to summarize the pharmacogenetic variants associated with response to metformin in T2D treatment.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
