What are the two types of Diabetes?

|
|
What causes Type I diabetes and when does it usually occur?
|
Type I diabetes usually occurs between 5 to 6 years of age. It is an autoimmune disease in which a pereson's immune system attacks the insulin and glucagon producing celss of the pancrease.
|
|
|
What causes Type II diabetes and when does it usually occur?
|
Type II usually appears after age 30. It is a milder form of the disease and found in 90% of all the people with diabetes. It results from an insulin resistance where the cells of the pancreas fail to make enough insulin or an insensitivity to insulin caused by a decrease in the number of insulin recepters.
|
|
|
Possible causes of diabetes
|
viral or bacterial infections, an overactive immune system, generic vulnerability, stress, poor nutrition
|
|
|
Treatment for Type II diabetes
|
Changing diet, regulating weight, and exercising.
|
|
|
Treatment for Type I
|
Insulinn management
|
|

|
What does HIV do to T-cells
|
HIV is a retro-virus that injects a copy of its own genetic material into the DNA of the t-cell. At some point, the t-cell will divide, replicating the HIV. The t-cell levels then begin to decline and the immune system becomes weaker.
|
|
|
How long is the first stage of HIV and what happens during it?
|
The first stage is typically 1 to 8 weeks, and the immune system destroys most HIV so people experience only mild symptoms that usually goes unnoticed.
|
|
|
How long is the second stage of HIV and what happens during it?
|
This may last for months or years--it appears to be a latent stage, but actually, HIV is constantly being replicated while t-cell concentration falls.
|
|
|
How long is the third stage of HIV and what happens during it?
|
Within 5 years, 30% of people move to stage 3 when t-cells are further reduced, immune function is impaired, and infections can occur.
|
|
|
How long is the fourth stage of HIV and what happens during it?
|
The number of t-cells drop from 1,000 to 200 or less per cubic milliliter. At this point, HIV has developed into AIDS. Without treatment, death would generally occur within a year or two.
|
|
|
Describe the neurological impact of age?
|
Some patients display signs of depression, paranoia, and hallucinations that signal the AIDS dementia complex.
|
|
|
What is immunocompetence?
|
Basically means the strength of the person's immune system--HIV progresses much more slowly in those whose immune system is stronger.
|
|
