* Increased fatigue : Due to inefficiency of cell to metabolise glucose, reserve fat of body is metabolised to gain energy. When fat is broken down in the body, it uses more energy as compared to glucose, hence body goes in negative calorie effect, which results in fatigue.
* Polydipsia : As the concentration of glucose increases in the blood, brain receives signal for diluting it and in its counteraction we feel thirsty.
* Polyuria: Increase in urine production is the result seen when excess of glucose is present in body. Body tries to get rid of the extra sugar in the blood by excreting it through the urine. This can also lead to dehydration because excreting the sugar which carries a large amount of water out of the body along with it.
* Polyphegia : The hormone insulin is also responsible for stimulating hunger. In order to cope up with high sugar levels in blood, body produces insulin which leads to increased hunger.
* Weight flactuation : Factors like loss of water (polyuria), glucosuria , metabolism of body fat and protein may lead to loss of weight. Few cases may show weight gain due to increased appetite.
* Blurry vision : Hyperosmolar hyperglycemia nonketotic syndrome is the condition when body fluid is pulled out of tissues including lenses of eye, which affects the ability of lenses to focus resulting in blurry vision.
* Irritability : It is one of the sign of high blood sugar because of the inefficient supply of glucose to brain and other body organs, which makes us feel tired and uneasy.
* Infections : Certain signals from the body is given whenever there is fluctuation of blood sugar (due to suppression of immune system) by frequent infections of fungal or bacterial like skin infection or UTI (urinary tract infection).
* Poor wound healing : High blood sugar resists the flourishing of WBC, (white blood cell) which are responsible for body immune system. When these cells do not function accordingly, wound healing is not at good pace. Secondly, long standing diabetes leads to thickening of blood vessels which may affect proper circulation of blood in different body parts.

Symptoms of type 1 diabetes are often dramatic and come on very suddenly.

Type 1 diabetes symptoms –

•constant thirst
•severe fatigue
•increased urination
•increased appetite
•weight loss
•blurred vision
•vomiting

Hypoglycemia Symptoms
Because epinephrine, one of the hormones that is activated by hypoglycemia, comes from the central nervous system, the majority of early symptoms of hypoglycemia are related to the nervous system.
Common symptoms of hypoglycemia include the following:
Trembling
Clamminess
Palpitations
Anxiety
Sweating
Hunger

Because the brain is deprived of glucose, a second set of symptoms follows:
Difficulty in thinking
Confusion
Headache
Seizures
Coma
Ultimately, death

Mild to moderate dehydration is likely to cause:

?Dry, sticky mouth
?Sleepiness or tiredness — children are likely to be less active than usual
?Thirst
?Decreased urine output — fewer than six wet diapers a day for infants and eight hours or more without urination for older children and teens
?Few or no tears when crying
?Muscle weakness
?Headache
?Dizziness or lightheadedness
Severe dehydration, a medical emergency, can cause:

?Extreme thirst
?Extreme fussiness or sleepiness in infants and children; irritability and confusion in adults
?Very dry mouth, skin and mucous membranes
?Lack of sweating
?Little or no urination — any urine that is produced will be dark yellow or amber
?Sunken eyes
?Shriveled and dry skin that lacks elasticity and doesn’t "bounce back" when pinched into a fold
?In infants, sunken fontanels — the soft spots on the top of a baby’s head
?Low blood pressure
?Rapid heartbeat
?Fever
?In the most serious cases, delirium or unconsciousness
Unfortunately, thirst isn’t always a reliable gauge of the body’s need for water, especially in children and older adults. A better barometer is the color of your urine: clear or light-colored urine means you’re well hydrated, whereas a dark yellow or amber color usually signals dehydration.

Take your pick.
