Complications of Diabetes Mellitus (DM)
Macrovascular Complications: Cardiovascular Diseases
Cardiovascular Disease and Atherosclerosis
Diabetes mellitus (DM) significantly increases the risk of cardiovascular diseases, primarily due to the progression of atherosclerosis. This condition is characterized by the buildup of plaques in the arterial walls, leading to narrowed and hardened arteries. The toxic effects of hyperglycemia, including increased generation of reactive oxygen species (ROS) and pro-inflammatory cytokines, play a crucial role in this process . Consequently, patients with DM are at a higher risk of cardiovascular events such as stroke and myocardial infarction, with the risk being 2- to 4-fold higher compared to the general population.
Postoperative Complications
DM is also associated with an increased risk of postoperative complications following non-cardiac surgeries. These complications include infections, wound healing disorders, renal insufficiency, and myocardial infarction. The risk is particularly higher in patients with insulin-dependent DM compared to those with non-insulin-dependent DM. Additionally, DM patients have a higher likelihood of postoperative reoperation, readmission, and mortality.
Microvascular Complications: Retinopathy, Nephropathy, and Neuropathy
Diabetic Retinopathy
Diabetic retinopathy is a common microvascular complication of DM, affecting the eyes. It results from damage to the blood vessels in the retina due to prolonged hyperglycemia. This condition can lead to vision impairment and, in severe cases, blindness. The prevalence of diabetic retinopathy is increasing, particularly in lower and middle-income countries .
Diabetic Nephropathy
Diabetic nephropathy, another microvascular complication, involves damage to the kidneys' filtering units, leading to chronic kidney disease. This condition is a significant cause of morbidity and mortality among DM patients. The pathogenesis involves metabolic and hemodynamic disturbances, including hyperglycemia, insulin resistance, and hypertension, which initiate damaging processes such as inflammation and ischemia .
Diabetic Neuropathy
Diabetic neuropathy affects the peripheral and central nervous systems, leading to symptoms such as pain, tingling, and loss of sensation. This condition can severely impact the quality of life and increase the risk of foot ulcers and amputations. The underlying mechanisms include oxidative stress and inflammation, which damage nerve cells .
Sexual Dysfunction: Erectile Dysfunction
Erectile dysfunction (ED) is a prevalent complication in men with DM, with a prevalence approximately 3.5-fold higher than in men without DM. The risk factors for ED in DM patients include sedentary lifestyle, obesity, and increased caloric consumption. While lifestyle changes can improve sexual function, specific treatments are often necessary to manage ED in DM patients.
Oral Complications
DM is associated with several oral complications due to the high vascularization and innervation of the oral cavity. These complications include periodontitis, dental caries, dry mouth, oral mucosal lesions, and taste disturbances. The pathogenesis involves metabolic disturbances such as hyperglycemia and immune dysfunction, which promote inflammation and damage to oral tissues.
Surgical Complications: Head and Neck Free-Flap Reconstructions
Patients with DM undergoing head and neck free-flap reconstructions are at a higher risk of postoperative and surgical complications, including free-flap failure, necrosis, and surgical site infections. These complications necessitate cautious surgical planning and aggressive treatment strategies for high-risk patients.
Inflammatory Mechanisms and Oxidative Stress
Chronic low-grade inflammation and oxidative stress are central to the progression of DM and its complications. Inflammatory cytokines such as interleukin-1β (IL-1β) and IL-18, processed by inflammasomes, play a significant role in the development of cardiovascular, renal, and ocular complications. Targeting these inflammatory pathways may offer new therapeutic strategies to manage DM complications more effectively .
Conclusion
Diabetes mellitus is associated with a wide range of complications, both macrovascular and microvascular, that significantly impact patients' quality of life and increase morbidity and mortality. Effective management of DM and its complications requires a comprehensive approach, including lifestyle modifications, strict glycemic control, and targeted therapies to address specific complications. Continued research into the underlying mechanisms of DM complications will pave the way for novel therapeutic strategies and improved patient outcomes.
