Is there a gene related to anorexia?
448849
I have just recently heard that they have come across some evidence that there is a gene that has been attributed to possibly causing some to be more prone to anorexia. My sister was anorexic and it was a very hard time for our family. She battled this disease for 10 years. My mom and I were talking during the course of it and I reminded her that when my sister was 6 months old she would not eat. It was like she was not hungry. We had to give her medicine to stimulate her hunger. So I do tend to believe this new evidence is correct.

anorexia develops over a period of time, not just overnght.\n\nwhile anorexics get hungry in the beginning, eventually the hunger goes away as your body adjusts and goes into starvation mode. also, they typically deal with the hunger by ignoring it.\n\nit really depends from case to case, it's not a specific thing.\n\nanorexia does occur in adults, just google it.

when i was 15 i had anorexia.  you eventually dont realize that you need to eat.  i wont say you lose the hunger feeling because it is replaced by other pains, but you just forget.

I am seriously not going to sit here and tell you how to run your life but it is dangerous.  If being anorexic really makes you proud and happy then by all means, I am not the person to tell you any differently.  As far as finding a website to help you in your quest for self-destruction.  No I do not know of any.  I am sorry I cannot be more help in that department.  However what I can tell you is that my sister suffered from anorexia for a very long time.  She went through spells where she wouldnt eat and then she went through spells where she "purged."  She was extremely unhealthy looking and she was just unhappy all around.  I think that there's always a reason why people are anorexic and it's not always due to the fact that they think they are fat!  It's truly an obsessive thing.  There is a plethera of medications out now to help treat Obsessive disorders.  Maybe you should try one of those so you don't end up getting disgustingly skinny.  I wish you the best of luck in whichever route you choose!  If you ever need someone to talk to...I will listen!

some people are born with good genes and have been reared in an environment where food is a neccesity and not a crutch. they eat to live...not live to eat. there have been some recent studies showing a "fat gene" that links obesity to an addiction....and not just weak and lazy people who don't have the will power to diet and exercise.

NO bulimia is not inheritable, but lemme expand on chi_o_dawnie's answer.\n\nThere are some psychological tendencies that people have which are somewhat heritable. For example, some people have highly addictive personalities. They may have extensive histories of alcoholism. Is alcoholism it inherited? No, it's not. But that person whose from a family of alcoholics can inherit the tendency to become addicted to alcohol. But if and only they begin drinking a lot! If that person never drinks, then they can never be an alcoholic.\n\nSame with bulimia. If you inherit the kind of tendencies that compel you to exercise extreme control over things like your *weight* then you will have a much easier time becoming a bulimic than another person who doesn't have those innate, inherited psychological tendencies.\n\nBut let's not forget that ENVIRONMENT plays a big part. It certainly does not help that the media bombards us with images of extremely skinny people, and society pressures us to emulate them.\n\nSo if you add a high-pressure environment, plus an inherited tendecy to be a control freak, you have the perfect combination for a home-grown bulimic.

In some cases, obesity. Some cases it's just inherited. Depends on the type of Diabetes.

Few genes are known to influence both diabetes-related traits and birth weight. Positive associations with both phenotypes have been shown for the insulin gene (INS) variable number of tandem repeats (VNTR) locus [8-10], a microsatellite polymorphism in the insulin-like growth factor 1 gene (IGF1) [11,12] and the glucokinase gene GCK(-30) polymorphism [13]. There is evidence that a single nucleotide polymorphism in complete linkage disequilibrium with INS-VNTR classes I and III (rs689) is functional [14]. Despite this, studies attempting to replicate the INS-VNTR and IGF1 associations have produced inconsistent results [15-20]. Replication of any genetic association study is vital for determining whether the observed association is real, since it increases the cumulative sample size and helps to guard against the low a priori odds of a variant altering a phenotype, which may hinder any single study [21,22].\n\nRecently, Day et al. [23] reported that genetic variation in the GH/CSH gene cluster, which includes growth hormone (GH1; chromosome 17q23), is associated with altered 1-year weight and adult insulin resistance in UK Caucasian males aged 59–72 years. Variation in a highly polymorphic microsatellite marker, CSH1.01, was dichotomised into allele lineages based on possession of a dinucleotide repeat allele (D1; D2 (subset)) or a tetranucleotide repeat allele (T). In male subjects from north and east Hertfordshire, TT homozygotes had a 64.6 % (22.8 pmol/l) or 66.5 % (23.2 pmol/l) higher fasting insulin compared to D1D1 homozygotes (P = 0.001; n = 206) and D2D2 homozygotes (P = 0.009; n = 92), respectively. The TT genotype was also associated with a 5.3 % (547 g) reduction in weight at 1 year compared to the D2D2 genotype (P = 0.008; n = 270) but this difference was not observed when compared to the D1D1 genotype (P = 0.24; n = 593). There was no association of genotype with birth weight, and no association with any measured phenotype in females.\n\nStrong linkage disequilibrium occurs across the 66.5-kb GH/CSH gene cluster such that variation in two or more of the genes, inherited together, may reduce growth in early life while predisposing to disease later in life [23]. The gene cluster is an excellent candidate region for predisposing to restricted early growth and later insulin resistance. Placental growth hormone (GH2) and chorionic somatomammotropin (human placental lactogen) hormones 1 and 2 (CSH1 and CSH2), are expressed in the placenta and are involved in regulating fetal glucose supply and growth [24,25]. GH1, through transcriptional regulation of the gene for insulin-like growth factor-I (IGF1) and related genes, has a critical role in the regulation of postnatal growth [26]. Exogenous growth hormone administration alters glucose metabolism both in vitro and in vivo [27], whilst growth hormone deficiency and acromegaly are characterised respectively by sensitivity and resistance to insulin [28]. In addition, lower circulating IGF-I concentrations are associated with higher risk of impaired glucose tolerance or type 2 diabetes [29].\n\nWe sought replication of the associations reported by Day et al. [23]. We used healthy subjects (483 fathers, 479 mothers and 434 children) from a population-based consecutive birth study to assess the role of CSH1.01 variation in measures of fetal and postnatal growth and adult insulin resistance, as measured by fasting insulin concentrations and Homeostasis Model Assessment of Insulin Sensitivity (HOMA %S).\nCommon variants in the GH-CSH cluster are excellent candidates for contributing to common variation in fetal/infant growth and adult insulin resistance. The placentally-expressed CSH1, CSH2 and GH2 genes have key roles in the regulation of fetal glucose supply and growth [24,25], while GH1 has a critical role in postnatal growth and glucose metabolism [26-29]. A previous study reported that a microsatellite polymorphism in this cluster, CSH1.01, was associated with reduced wei

I'm sure it does.  Anorexia also causes problems with the rest of your body.  Hair becomes brittle and falls out, heart failure may occur and your body starts to shut down because there's no nourishment.

There is no such thing unless you are anorexic. You don't need to gain.  You want to gain.  If you are under 25 years old, do not try to gain weight.  You will dramatically gain weight once you hit 25 years and you will regret trying to gain it in your teens and early twenties.

anorexia you mean.. its an eating disorder where you dont let yourself eat much and have an extremely negative body image

it may be something other than anorexia. if you were anorexic you would be obssessed with being thin, and not eating on purpose. maybe you should talk to a doctor about it.

NO!\nThis is a common misconception, but in order to be classified as anorexic, you MUST be underweight.\nAnorexia is different from just self-starvation, and in order to be clinically diagnosed with anorexia, you MUST have the following symptoms.\n-low body weight (less than 85 percent of normal weight for height and age)\n-a distorted body image\n-an intense fear of gaining weight.\n\nIf you don't have all of those, then it is NOT anorexia nervosa.\nThere are other conditions that are commonly misinterpreted and referred to as anorexia, but these are not technically anorexia without the above symptoms.\nHopefully that cleared it up for you!

it may not be anorexia yet but it can lead to it with the behaviors she is exibiting. talk to her alone about it and see what her reaction is. let her know that you think she is fine the way she is. if that goes nowhere and you are still worried you may want to get her parents involved.

anorexia nervosa and bulimia nervosa.

She was in a British mag this week (Heat)admitting that she has an eating disorder and is really unhappy with her size. She would like to go back to the size she was a bout a year ago but became addicted to losing weight. Most eating disorders are neither anorexia or bulemia but a mix of both- I suspect that Nicole is suffering from a mix of both.
