Whether a diabetic patient is experiencing leg cramps or a healthy person is experiencing leg cramps, most of them are triggered by blood circulation disorders. Blood circulation disorders can lead to muscle ischemia and hypoxia. Especially in diabetic patients, the blood vessels of the lower limbs will have decreased vascular elasticity due to the disease state. Once standing or sitting for a long time, blood circulation in the lower limbs will be obviously impaired. The veins with decreased elasticity cannot squeeze the blood back to the heart sufficiently, and the muscles of the legs are not supplied sufficiently, and the symptoms of cramps occur. In this case, in addition to actively treating and controlling the primary disease, it is important to avoid prolonged standing or sitting. You can often elevate your legs slightly above the heart, so that the blood circulation in the lower limbs is relatively smoother. Usually, you can use local physical therapy to promote blood circulation in the legs, which can prevent the occurrence of cramps.
