Is diabetes hereditary?

i dunno i asked around and nobody else knows can anyone help me?

Type 2 definitely is partly hereditary - that doesn't mean you'll definitely get it, for most people it just means that if they have family members with diabetes then they will be more prone to it, but life style is still the over riding factor for most people.

Mody diabetes is definitely v strongly hereditary - infact I think it's part of its deffinition.

We don't know what causes type 1 diabetes - it's an auto immune disease possibly triggered by a virus. There is growing evidence that genetics makes you more prone to it. I have it and no one related to me does, but I know 2 families with mum and dad both type 1 and in both of them all their children have type 1 too. All v anecdotal but check out http://www.jdrf.org/index.cfm?page_id=10... for more scientific info.

Hope that helps! xx

Inasmuch as your likelihood of getting it increases if someone in your family has it, particularly a parent or sibling, yes it is.
to some extent
it depends on how many people in your family have it and then that shows your likeliness.
not really, but if u have a diabetic relative(parents) you are more likely to get it. just take care of your self, exercice, do not eat too much sugar
No but -
"You are at higher risk for developing type 2 diabetes if ... you have close relatives with diabetes, especially type 2 diabetes. "

Diabetes mellitus is a disorder of metabolism where either insulin is lacking(typeI) or it can't act(typeII)...resulting in high sugar level(insulin keeps it in control).

Diabetes mellitus also tends to run in families. This means that the child of a parent with diabetes has a higher chance of developing the same type of diabetes than a child whose parents do not have diabetes. However, only a small percent of people who inherit the genes for Type I diabetes (insulin-dependent) actually go on to develop the disease. Genes are units of material contained in a person's cells that contain coded instructions as for how certain bodily characteristics (such as eye color) will develop. All of a person's genes come from his/her parents. So why do some people who inherit the genes for Type I diabetes go on to develop the disease while others do not? The answer is that in many cases (but not all), Type I diabetes may occur because of having the genes for this disease as well as having a delayed reaction to a virus that damaged the pancreas several years earlier.

There is a subgroup of people with Type I diabetes in which the cause is not known. This is known as idiopathic diabetes. In these individuals, the need to take insulin injections can very from time to time. In other words, sometimes it will be necessary for them to take the insulin injections and other times it will not.

Unlike Type I diabetes, a greater percentage of people who inherit the genes for Type II diabetes (non-insulin-dependent) actually go on to develop the disease. Thus, there appears to be a strong genetic component to Type II diabetes. However, it is generally overweight people who go on to develop this form of diabetes. Obese (very overweight) people are particularly likely to develop the Type II form, rather than the Type I form. Such people tend to have very large bellies
