If a diabetic patient walks unsteadily, it may be caused by a variety of reasons. Serious cardiovascular and cerebrovascular diseases, hypoglycemic reactions and other conditions may be life-threatening; diabetic foot, diabetic peripheral neuropathy and other diseases are relatively less likely to be life-threatening in the short term. Diabetic patients with unstable blood glucose control will develop atherosclerosis and related complications, and if the walking instability is caused by cerebrovascular accidents, it is possible to jeopardize the patient’s life. Unsteady walking in diabetic patients may also be caused by complications such as diabetic foot, diabetic peripheral neuropathy, and atherosclerotic occlusive disease of the lower extremities. Generally these complications do not cause life-threatening problems in the short term, but if they are not controlled for a long period of time, they may still endanger the patient’s life, such as sepsis and infectious shock. In addition, diabetic patients may suffer from hypoglycemic reaction, which causes dizziness, unsteady walking and other symptoms, and in serious cases, it may lead to coma, which may also be life-threatening. Therefore, diabetic patients who experience unsteady walking should go to the hospital as soon as possible.
