Symptoms of Diabetes

Diabetes is related to the increase or decrease in the level of blood sugar. Diabetes shows two types Type I and Type II. The symptoms shown by both types of diabetes are different.

Symptoms shown by Type 1 diabetes

This type of diabetes is caused by infection of virus, which damages the insulin producing cells of pancreas
In this type, less amount of insulin is produced. Insulin increases permeability of the tissue for absorbing glucose, but less availability of insulin reduces absorption of glucose in the tissue.
Glucose is necessary for production of energy in the form of ATP
The patient shows symptoms like vomiting and nausea in absence of energy
To get energy body utilizes fats of muscular tissue, which causes reduction in body weight and dehydration
Coma or sometimes death

Symptoms shown by Type 2 diabetes

Fatigue

Type 2 diabetes is caused by increase in blood sugar
To get energy body uses fats of the adipose tissue. More energy from fats is required to do physical activities as compared to the energy from glucose source.
Use of tissue fats for getting energy causes fatigue

Polydipsia

The level glucose in the blood increases, when it is not absorbed by the tissue
High level of glucose in the blood stimulates drinking of water for dilution

Frequent urination

Frequently person becomes thirsty and drinks lot of water, this leads to more formation of urine
To reduce level of blood glucose body excretes large amount of urine

Hunger

Body cells do not get glucose for production of energy, this stimulates the part of the brain which controls hunger of a person
The diabetic patient frequently becomes hungry and eats many times in a day

Changes in body weight

The patient loses body weight, due to utilization of tissue fats for production of energy, which is required for different physical activities
Sometime person consumes food many times leads to increase in body weight

Neuropathy

It is found that increase in level of sugar damages the neurons of nervous system
The limb extremities like hands, fingers and feet become senseless

Blurred vision

In diabetes fluid from cells of the eye lenses is pulled outside the lenses, which affects the ability of focusing leading to blurred vision

low healing of wounds

WBC's are involved in defense mechanism of immune system. High level of sugar in the blood affects the production of WBC.
Less amount WBC in blood slows down the wound healing
Blood vessels become thick resulting in disturbance in circulation of blood in different parts of the body

Other symptoms

Dry and itchy skin
Infection of virus, bacteria and fungus due to weak immune system
Less supply of glucose to the brain and other parts of the body leads to irritability, tiredness and discomfort
