Ancient Civilizations
Diabetes mellitus is also known as "pissing disease" due to excessive urination. Early treatment includes changes in diet and herbal remedies.
Diabetes is a chronic metabolic disease characterized by high levels of blood glucose, resulting either from defective insulin production by the body or resistance to insulin. It is generally divided into two major types of diseases, namely: Type 1 diabetes-in which there is very little to no insulin production due to the autoimmune effects of the pancreas; and Type 2 diabetes-generally due to obesity and life factors or influences leading to insulin resistance. It is one of those diseases that hardly leaves some people in their respective parts of the world alone, with estimates by the World Health Organization suggesting over 422 million people live with diabetes-a number expected to continue growing.
In any case, the impacts of diabetes are many-sided, and among other health complications, it holds a position of importance, such as cardiovascular diseases, kidney failures, and neuropathy. The economic consequence is also high in that healthcare costs for the management of diabetes and complications arising strain the health systems. All these impacts, therefore, need to be put under effective management and treatment to improve the quality of life for those affected.
Diabetes mellitus is also known as "pissing disease" due to excessive urination. Early treatment includes changes in diet and herbal remedies.
Scientists successfully isolated insulin in 1921, revolutionizing the treatment of type 1 diabetes and offering renewed hope to countless patients.
The introduction of oral hypoglycemic agents extends the circle of treatment for type 2 diabetes. More focused management strategies are developed.
Novel therapeutic approaches represented:
Substantially improved the outlook for diabetes treatment.
Insulin and Insulin Analogs
Oral Hypoglycemic Agents (OHAs)
GLP-1 Receptor Agonists
Sodium-Glucose Cotransporter-2 (SGLT2) Inhibitors
Thiazolidinediones (TZDs)
Alpha-Glucosidase Inhibitors
Glucagon Receptor Antagonists
Bile Acid
Sequestrants
Insulin is vital for managing diabetes, particularly in type 1 and advanced type 2 patients. Traditional insulin and analogs like glargine, lispro, and aspart improve patient outcomes by closely mimicking physiological insulin profiles, activating insulin receptors to enhance glucose uptake and regulate blood glucose levels.
Metformin - As a widely used first-line treatment, metformin primarily works by reducing hepatic glucose production and enhancing insulin sensitivity. This dual action helps lower blood sugar levels effectively.
Sulfonylureas and Meglitinides - These medications stimulate pancreatic beta cells and promote the secretion of insulin. Increased insulin levels help lower the level of blood glucose.
DPP-4 Inhibitors - DPP-4 inhibitors are a class of oral hypoglycemic drugs that inhibit the enzyme dipeptidyl peptidase-4 (DPP-4). DPP-4 inhibitors enhance incretin hormone activity, which aids insulin secretion and reduces glucagon release.
Liraglutide and semaglutide, amongst others, have emerged as one of the most reviewed GLP-1 receptor agonists in both diabetes management and the treatment of obesity. These drugs act by mimicking the action of a naturally occurring hormone, GLP-1, which is secreted in response to nutrient intake. They thus bind to GLP-1 receptors, stimulating insulin secretion in a glucose-dependent manner and hence lower blood glucose.
These drugs include empagliflozin and canagliflozin, which are classified under a class of SGLT2 inhibitors. The mechanism of their action involves inhibiting the protein SGLT2 in the kidneys to reduce blood glucose levels. This inhibition reduced glucose reabsorption from the renal tubules and enhanced its excretion through the urine at higher rates.
Thiazolidinediones (such as pioglitazone and rosiglitazone) primarily lower blood glucose by enhancing insulin sensitivity in adipose tissue, muscle, and liver.
Acarbose and miglitol, along with other alpha-glucosidase inhibitors, can reduce post-meal blood sugar levels by stopping the absorption of carbohydrates in the intestine.
Glucagon receptor antagonists (such as monoclonal antibodies or small molecules targeting glucagon) aim to lower blood glucose levels by reducing hepatic glucose production and indirectly promoting insulin secretion through improved glucose homeostasis.
Medications like colesevelam are bile acid sequestrants that reduce the level of blood sugar by binding to bile acids, which inhibit their reabsorption. This in turn improves cholesterol levels.
Regenerative Medicine
Gene-based Therapy
Immunomodulatory Therapies
Targeted Therapeutics
Current research testifies to the effectiveness of islet transplantation regarding the restoration of endogenous insulin secretion, which improves glycemic control and further decreases the complications arising from diabetes. However, challenges in islet viability, functional integration, and immune rejection remain some of the critical areas of investigation.
Gene-based therapy is a new approach that involves the modification of genes either responsible directly for insulin production or responsible for the metabolism of glucose. In gene-based therapy, usually, the modified genes are introduced into the patient's cells to correct or replace faulty genes involved in insulin regulation.
Immune modulation in the treatment of type 1 diabetes is one of the major thrusts to prevent autoimmune beta-cell destruction. Many studies are conducted with the purpose of identifying and developing immunomodulatory compounds that could protect residual beta cells. Immunomodulatory therapies change the response of the immune system toward a tolerogenic immune response against beta cells, which prevents their destruction.
The concept of personalized medicine is thus trying to realign the therapeutic approaches according to genetic, environmental, and lifestyle factors of an individual in the treatment of diabetes, offering a new ray of hope in better management of the disease.
Closed-Loop Systems and Artificial
Pancreas
Gut Microbiota and Metabolic Health
Anti-inflammatory Approaches
Gene Editing Technologies
Biologics and Novel Drug Formulations
Emerging closed-loop systems and artificial pancreas technologies are at the core of the revolution in diabetes management, thus enabling a far more automatic and responsive insulin therapy compared to what has ever been possible. These systems integrate continuous glucose monitoring with automated insulin delivery through seamless feedback mechanisms that almost perfectly mimic the function of a healthy pancreas.

Gut microbiota has emerged as a very indispensable field in research with regard to the role it plays in glucose metabolism, regulation of insulin sensitivity, and generally in metabolic health. Evidence is emerging to show that gut microbiota variation and diversity can importantly cause changes in metabolic disorders such as type 2 diabetes.

Chronic inflammation is considered a critical contributor to the pathogenesis and development of diabetes, partly through the regulation of insulin resistance and metabolic changes. Thus, targeting inflammation with pharmacological interventions provides a promising approach for the management of metabolic health and treatment of diabetes.

Innovations in gene editing technologies, including CRISPR-Cas9, could offer potential to correct genetic defects driving diabetes.
Biologics, especially monoclonal antibodies and fusion proteins, are emerging as targeted therapies for diabetes. In addition, the development of novel drug formulations, such as liposomes, nanoparticles, depot formulations, and inhalable biologics, is playing a key role in improving the delivery, stability, and effectiveness of these biologic therapies.
