Mr. Huo, a 45-year-old white-collar worker, was diagnosed with diabetes. He experienced symptoms such as excessive thirst, frequent urination, fatigue, and blurred vision. His doctor advised him to adjust his diet by reducing high sugar and high-fat foods and increasing the intake of vegetables, fruits, and whole grains. Exercise, such as brisk walking and swimming, was also recommended.

Medications, including glucose-lowering drugs and insulin, were prescribed. Despite his efforts to follow the doctor's advice, Mr. Huo's irregular lifestyle and work stress led to his condition worsening. He developed symptoms of blurred vision, weakness in his legs, and foot ulcers, eventually collapsing and being hospitalized. The doctor diagnosed him with diabetic ketoacidosis. It highlights the importance of managing diabetes and recognizing worsening symptoms. Blurred vision, leg weakness, and foot ulcers are three significant symptoms indicating the deterioration of diabetes. It is crucial to prevent and control diabetes through a healthy diet, regular exercise, and maintaining a healthy lifestyle.
