If a patient develops atherosclerosis of the lower extremities, especially forming narrowing of the blood vessels, then intermittent claudication may occur. In addition, the patient may also feel pain in the lower limbs, and a feeling of weakness and lack of energy. For such patients, anti-atherosclerosis, lipid-lowering and plaque stabilizing drugs can be taken. In the clinic, such drugs as aspirin and atorvastatin can be taken to help prevent the progression of atherosclerosis, relatively speaking. In addition, it is recommended that patients should also combine lifestyle interventions and improvements, such as quitting smoking and drinking, low-salt and low-fat diets, regular work and rest, and weight loss exercises, in order to better prevent the progression of atherosclerosis. In addition, it is important to clarify whether the patient currently has diabetes, because if the blood sugar is abnormal, it will accelerate the progression of atherosclerosis.
