Lecture 23 Long Term Complications of Diabetes Flashcards
When can complications of type 2 diabetes be present
At any time of diagnosis
When can complications of type 1 diabetes be present
As early as 5 years after diagnosis
Macrovascular complications of diabetes
Coronary vascular disease
Cerebrovascular disease
Peripheral vascular disease
Microvascular complications of diabetes
Retinopathy
Nephropathy
Neuropathy
Effects of atherosclerosis in diabetes
- Ischaemic cerebrovascular disease - strokes
- Ischaemic Heart Disease - angina, myocardial infarctions
- Heart Failure - related to coronary disease and abnormal cardiac myocyte glucose handling
- Peripheral vascular disease
- Causes lower limb ischaemia, leading to ulcers and poor healing of these ulcers. Amputations are a potential outcome.
How do you prevent microvascular disease
- Good diabetes control
- Blood pressure control
- Lipid control
- Smoking cessation, weight, exercise
What are the features of Non-Proliferative Diabetic Retinopathy
• Retinal capillary dysfunction, platelet dysfunction, blood viscosity abnormality
What are the features of proliferative diabetic retinopathy
• Retinal ischaemia, new blood vessel formation, vitreous haemorrhage, retinal tears/detachment.
How is retinopathy treated
Laser photocoagulation
Improve glycemic control
Features of Nephopathy
Microalbuminuria
Glomerular hypertension
Progressive renal failure
Prevention and treatment of nephropathy
Screening urine for albumin Diabetes control ACE inhibitor Angiotensin receptor blockade Renin inhibition For hypertension control
Sensory neuropathy can lead to
objective loss, particularly in feet & lower legs; subjective symptoms, especially paresthesia
Autonomic neuropathy can lead to
GI effects (stomach, intestines), or the cardiovascular system (tachycardia, blood pressure fluctuations). Watch out for silent myocardial infarction
What is Charcot Foot
a condition causing weakening of the bones in the foot that can occur in people who have significant nerve damage (neuropathy). The bones are weakened enough to fracture, and with continued walking, the foot eventually changes shape
