The Human body requires sugar for growth and energy for its daily activities. The food we eat ultimately converts into glucose (a form of sugar) in the body.

Insulin is a hormone which is secreted by an organ known as Pancreas which helps our body to take up glucose and use it. It also keeps our glucose in check so the body doesn’t suffer due to excess of sugars. Diabetes occurs when the body cannot make use of the glucose in the blood for energy because either the pancreas is not able to make enough insulin or the insulin that is available is not effective in controlling the glucose.

Diabetes tend to run in families that is if any one or more of your family members have this disease then you have more chances of getting the disease. People who eat too much and put up a lot of weight and don’t exercise daily also have high chances.


  • Passes urine often because his kidneys are trying to remove the excess glucose from his body
  • Is hungry all the time
  • Keeps drinking a lot of water
  • Loses weight
  • His wounds take a long time to heal
  • Feels tired easily
  • Can have frequent infections


One of the most important complications of Diabetes which accounts for frequent visits to the doctor’s clinic is the development of Diabetic foot. Three main factors leading to this condition are:

  • Damage to our nerves makes us lose any feeling in our foot. Even if we get hurt and a small wound forms we may not know.
  • Damage to our blood vessels through which blood flows. We all know that nutrition get through all our body only through blood and oxygen. Diabetes makes sure the foot doesn’t get enough blood or oxygen so healing will take a long time.
  • Infection

A major disadvantage is that the patient will not know the discomfort his foot is suffering from. So he will continue to use his affected foot. Finally his skin will break down and leads to formation of an ulcer.


  • You feel Continuous pain in the foot.
  • There is a red area in your foot
  • Your foot has started to swell and there is Itching
  • You walk with a limp
  • Your feet feel numb with so sensation.

Many patients report to the doctor only after an ulcer develops. After this stage frequent cleaning with disinfectants and applying a dressing (a bandage wrapped around your foot) are required.


Extra care must be given to your feet. Ignorance may only lead to deeper damage and even your bone may get infected. So follow these important instructions

  • Examine your foot everyday for any wounds even if it’s very small. Report to the doctor immediately if you see a wound, if there is a red area anywhere in the foot or if you feel any pain.
  • Wash your feet every day with soap and water and a disinfectant. You can also apply a moisturizer everyday to prevent skin from drying up. It keeps the skin soft and smooth.
  • Wear shoes and socks at all the times. Always choose strong and comfortable shoes. Special slippers are now available that that designed especially for Diabetic patients.
  • Regular exercise will improve bone and joint health in your feet and legs, improve circulation to your legs, and will also help to stabilize your blood glucose levels.
  • Do not smoke or drink alcohol because both will slow down healing.
  • Protect your feet from hot and cold.
  • Keep the blood flowing to your feet.
  • Finally follow a healthy diet, take your medications regularly, check your blood sugar time to time, exercise everyday, and maintaining good communication with your doctor. These are essential in keeping your diabetes under control.
