Diabetes affects how the body uses blood glucose, also known as blood sugar. This condition, characterized by an overabundance of blood sugar in the body, comes in permanent and reversible varieties. Complications from uncontrolled diabetes or poorly monitored diabetes can include a variety of conditions impacting the legs. According to MayoClinic.com, these complications include various types of neuropathy, restless leg syndrome and leg ulcers.
Diabetic Neuropathy
Diabetic neuropathies refer to a group of nerve disorders caused by diabetes. The National Diabetes Information Clearinghouse notes that approximately 60 to 70 percent of diabetics develop neuropathy of some form, many of which impact the legs. Peripheral neuropathy--nerve damage to the legs--can cause tingling, numbness and pain in the legs, while autonomic neuropathy--damage to nerves controlling the heart, blood pressure and glucose levels--may interfere with circulation, including circulation of the legs. Proximal neuropathy causes weakness in the legs. While neuropathy may come from other diseases, the presence of these symptoms may warrant medical attention to check for diabetes.
Restless Leg Syndome
Restless legs syndrome, or RLS, presents as an unpleasant feeling in the legs and an uncontrollable need to move in order to stop the sensation, which can range from annoying to painful. Because RLS activates when the sufferer reclines, those with RLS find it difficult to sleep or rest. The National Institute of Neurological Disorders and Stroke reveals that chronic diseases, including diabetes, may cause RLS. As a possible symptom of diabetes, treatment to regulate blood sugar may help relieve irritation and pain from RLS.
Leg Ulcers
Leg ulcers, or recurring wounds that won't heal, may indicate diabetes, according to the Cleveland Clinic. Neurotrophic ulcers, most often associated with diabetes, occur at increased pressure points on the bottom of the feet, and generally present as pinkish-red or brownish-black sores surrounded by calloused skin. Nerve damage that causes loss of sensation in the foot, combined with circulatory damage common in diabetics, creates a higher risk of leg ulcers. This symptom can become more serious, so if unexplained leg ulcers occur, patients should see a physician.
