Diabetic Neuropathy and Foot Ulcer Pathophysiology in Type 2
Diabetes
1. What is a common complication of type 2 diabetes mellitus that can lead to
foot ulcers?: Peripheral neuropathy.
2. How does sensory neuropathy contribute to foot ulcers in diabetic patients?: It
exposes tissues to increased trauma and pressure due to decreased pain sensation and proprioception, leading to
unawareness of tissue injury.
3. What effect does autonomic neuropathy have on blood circulation in diabetic
patients?: It causes loss of autonomic tone, leading to shunting of blood from arterioles to veins and decreased
tissue perfusion.
4. What are the consequences of motor neuropathy in the context of diabetic
foot health?: It can cause atrophy of small intrinsic foot muscles, leading to toe clawing and abnormal pressure
redistribution to the metatarsal heads.

, 5. What are some essential measures to reduce the risk of foot ulcers in diabetic
patients?: Glycemic control and proper foot care, including regular inspection, moisturization, and well-fitting
shoes.
6. What distinguishes venous stasis ulcers from diabetic foot ulcers?: Venous stasis
ulcers are commonly located near the ankles and accompanied by brawny skin discoloration, while diabetic ulcers can
occur on the plantar foot without such discoloration.
7. How does diabetic autonomic neuropathy affect sweat glands?: It leads to loss of
sympathetic innervation to sweat glands, resulting in decreased sweating and dry skin that is more susceptible to
fissuring.
8. What is the effect of lack of weight bearing on the risk of ulceration in diabetic
patients?: It reduces pressure on the plantar foot surface, thereby decreasing the risk of ulceration.
9. What is the role of total contact casting in diabetic plantar foot ulcer manage-
ment?: It is a method of pressure offloading that can help manage diabetic plantar foot ulcers.
