These are the classic symptoms of diabetes. In diabetes excess sugar builds up in blood and kidneys are forced to work more to filter and absorb that excess sugar. When kidneys are not able to keep up, the excess sugar gets excreted into urine. This triggers frequent urination and in turn more thirst as well.
Fatigue or Tiredness
Dehydration due to increased urination and body's inability to function properly as it is less able to use sugar for energy needs lead to constant tiredness in the body.
On losing sugar through frequent urination, a lot of calories are also lost. Also, diabetes keep the sugar from food to reach cells resulting in potentially rapid weight loss.
Increased levels of blood sugar bring out fluid from tissues, including the lenses of eyes. This affects ability to focus and vision.
Slow Healing Sores and Recurrent Infections
In diabetics infections are seen more commonly. High levels of blood sugar impair body's natural healing process and ability to fight infections. In diabetic women, bladder and vaginal infections become more common.
Tingling in Hands & Feet
Overload of sugar in blood can lead to nerve damage. Tingling and loss of sensation in hands and feet and burning pain in arms, hands, legs and feet is experienced in diabetics.
Red, Swollen and Tender Gums
Diabetes increases the risk of infection in gums. The gums may pull away from teeth making them loose. There is also a possibility of developing sores or pockets of pus in gums.
