Diabetes mellitus, a disorder where the body cannot properly regulate blood glucose, requires vigilant management to prevent serious complications like heart disease, kidney failure, and nerve damage. Early identification of symptoms is crucial, which for Type 1 diabetes can include sudden and severe thirst, frequent urination, extreme hunger, and rapid weight loss, while Type 2 diabetes often presents with more gradual versions of these symptoms, along with increased fatigue and blurred vision. The cornerstone of treatment involves rigorous blood sugar monitoring, dietary modifications, and physical activity, combined with medications—ranging from oral drugs like metformin for Type 2 to various forms of insulin for Type 1 and advanced Type 2. While not a cure, bariatric surgery is an increasingly recognized intervention for eligible patients with severe obesity and Type 2 diabetes, as it can often induce remission by altering gut hormones. The financial considerations for patients are substantial and lifelong, encompassing the costs of glucose test strips or continuous glucose monitors, medications, insulin pumps, syringes, and regular specialist visits, making access to affordable care and health insurance a critical concern for long-term health.
