a person with poorly controlled diabetes mellitus will develop

Individuals with diabetes who have poor blood sugar control are at risk of developing a range of complications. The severity and likelihood of these complications are correlated with both the degree of hyperglycemia and the duration of poor control. Typically, patients with inadequate blood sugar management may face health issues that escalate from mild to severe.

Initially, minor complications might manifest as sensory disturbances, such as tingling or numbness in the hands and feet, due to the neuropathic effects of elevated blood sugar. Additionally, vision issues, like blurred vision, are common early symptoms as fluctuations in blood glucose levels impact the eye's lens. As the condition worsens, more severe complications can arise, including cardiovascular diseases like heart disease and stroke, since chronic hyperglycemia can damage the blood vessels of the heart and brain. Diabetic nephropathy, a serious complication involving kidney damage, may lead to a decline in renal function or even renal failure. Prolonged poor blood sugar control can also result in impaired blood circulation in the lower limbs, increasing the risk of foot ulcers and infections, with the potential for amputation in extreme cases.

Hence, it is imperative for individuals with diabetes to regularly monitor their blood sugar levels and adhere to their physician's treatment recommendations. Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and abstaining from smoking, can aid in managing blood sugar levels and reducing the risk of complications. Should any diabetes-related symptoms or complications arise, prompt medical attention is advised, and treatment plans should be adjusted under a doctor's supervision.
