Can high blood sugar cause weakness and soreness in both legs?

Elevated blood sugar levels can generally cause weakness and soreness in both legs, usually due to poor blood glucose control, improper diet, or accompanying cerebrovascular diseases.

1. Poor Blood Glucose Control

Patients with high blood sugar need to promptly use antidiabetic medications under a doctor's guidance to control their glucose levels. If these medications are improperly used, resulting in inadequate glucose control and persistently high blood sugar, the body cannot effectively utilize glucose for energy. This leads to an energy deficit, commonly manifesting as weakness and soreness in both legs.

2. Improper Diet

In addition to using antidiabetic medications, patients with high blood sugar should also maintain a healthy diet. They should avoid foods high in sugar and sugary beverages. Poor dietary habits can easily lead to blood glucose fluctuations, causing weakness and soreness in both legs. Additionally, picky eating or unbalanced diets may result in electrolyte imbalances, such as hypokalemia (low potassium), which can also commonly lead to weakness and soreness in both legs.

3. Cerebrovascular Disease

If patients with high blood sugar also have cerebrovascular conditions such as cerebral embolism, the onset of such diseases often damages the central nervous system, leading to weakness and soreness in both legs.
