Foot Swelling
Poor circulation and fluid retention — both linked to diabetes — can cause swelling in the feet and ankles.
9. Frequent Foot Cramps
Low circulation or nerve dysfunction due to high blood sugar can trigger cramps, especially at night.
10. Darkened Skin Around the Ankles
A condition called acanthosis nigricans, often linked to insulin resistance, can cause the skin to darken or thicken.
11. Changes in Nail Color
Yellowish or brittle toenails can indicate fungal infections, which are more common in people with elevated blood sugar.
