Nerves in the legs and feet are often most affected by neuropathy. This can cause you to lose sensation to your feet and legs. Sores and cuts can go unnoticed and lead to infections. In some extreme cases, infections can become severe and lead to ulcers. Over time, this can cause irreparable damage to the soft tissue and lead to the loss of toes or even your foot.

The main symptoms of diabetes are three – polydipsia, polyphagia and polyuria. These mean increased thirst, increased hunger and increased frequency of urination. In addition patients complain of feeling very tired and weight loss and loss of muscle bulk. Type 1 diabetes can develop quickly, over weeks or even days whereas type 2 diabetes may develop gradually.
Type I diabetes usually occurs in people who are below the age 20 and that is why it is also called as juvenile diabetes. In this type, the body becomes partially or completely unable to produce insulin. Type I diabetes is an autoimmune disease. In this, your immune system attacks the pancreas from where the insulin is produced, thereby making the pancreas inefficient or unable to produce insulin. Type I diabetes cannot be prevented, it can only be controlled with healthy lifestyle changes.
Nerve damage from diabetes is called diabetic neuropathy and is also caused by disease of small blood vessels. In essence, the blood flow to the nerves is limited, leaving the nerves without blood flow, and they get damaged or die as a result (a term known as ischemia). Symptoms of diabetic nerve damage include numbness, burning, and aching of the feet and lower extremities. When the nerve disease causes a complete loss of sensation in the feet, patients may not be aware of injuries to the feet, and fail to properly protect them. Shoes or other protection should be worn as much as possible. Seemingly minor skin injuries should be attended to promptly to avoid serious infections. Because of poor blood circulation, diabetic foot injuries may not heal. Sometimes, minor foot injuries can lead to serious infection, ulcers, and even gangrene, necessitating surgical amputation of toes, feet, and other infected parts.

Diabetes is a number of diseases that involve problems with the hormone insulin. Normally, the pancreas (an organ behind the stomach) releases insulin to help your body store and use the sugar and fat from the food you eat. Diabetes can occur when the pancreas produces very little or no insulin, or when the body does not respond appropriately to insulin. As yet, there is no cure. People with diabetes need to manage their disease to stay healthy.
