it typically involves excessive weight loss and is usually found to occur more in females than in males . an individual with anorexia nervosa may exhibit a number of signs and symptoms that may be present but not readily apparent .
clinically they may present with symptoms of 
 distorted body mass index range ; of less than 17.5.amenorrhea.fearful of even the slightest weight gain.cooking elaborate dinners for others , but not eat the food themselves.hypotension orthostatic hypotension , bradycardia , or tachycardia.may frequently be in a sad , lethargic state.swollen joints , hair loss or thinning.constipation , electrolyte imbalance.lanugo . 
 
the causes for anorexia nervosa have been attributed to risk factors such as , family history , obesity , weight concerns , psychiatric comorbidity , and substance abuse .
although anorexia nervosa is widely described in the western literature , it is rather rare in nonwestern cultures . in india ,
patients chiefly present with refusal to eat , persistent vomiting , marked weight loss , amenorrhea , and other somatic symptoms , but rarely show over activity or disturbances in body image .
however , the management of the disorder does not markedly vary irrespective of the cultural and ethnic variations in the clinical picture .
it calls for the involvement of a multidisciplinary approach . in this article , the authors report a case of atypical anorexia nervosa in an attempt to contribute to the indian literature of eating disorders that currently lacks clinical reports on the same .
case of mrs s , a 25-year - old female , married for 5 years , educated up to 10th standard , currently a homemaker , hailing from an upper social class hindu ( marvadi ) family , living with husband 's family in urban bangalore ; presented to our tertiary care center with complaints of gradual loss of weight , recurrent episodes of vomiting , from a period of 2 years , menstrual irregularities from 1 year and amenorrhea since 6 months , with a probable precipitating factor being husband 's critical comment about her weight .
patient was reported to be dull and inactive most of the times since her marriage able to carry out her activities of daily living adequately . with symptoms of weight loss and amenorrhea ,
a series of investigations were conducted in the background of suspected tuberculosis , anemia for evaluation and abdominal tumors .
she was further evaluated by a gastroenterologist ; an intestinal biopsy was done to rule out malabsorption syndrome .
gynecological opinion was taken in the background of amenorrhea and infertility , and was advised endometrial biopsy . endocrinologist was seen and investigations conducted were normal .
the patient was referred to psychiatric consultation by her treating physician as she appeared less cheerful , dull , and inactive and decreased interest in sex . during psychiatric interview
it was difficult to establish rapport and mrs s was uncooperative . with persistent probing , she expressed low mood , easy fatigability , apathy , decreased attention and concentration , bleak , and pessimistic ideas about future .
information was elicited by mrs s husband , revealed an incident during their early days of marriage when he had casually remarked of her being slightly heavy near her flanks and thighs and that she would look more beautiful if she reduced it . since then
she followed a change in the diet pattern with complete avoidance of all foods with high caloric value .
at times hide and eat , and/or would secretly go into the bathroom and induce vomiting . after repeated sessions , the patient opened up to the clinician . when questioned about her purging behavior , she reported of being unable to tolerate the guilt associated with eating excessively .
premorbid personality assessment revealed an over concern about physical appearance , inspired by skinny models .
she reported of wanting to impress her husband with her beauty as he was fond of thin looking girls .
she recalled that her husband would repeatedly compare her with thin looking girls on television and magazines .
she eventually developed a morbid fear of looking fat and ugly , began eating a handful of fennel seeds to facilitate digestion .
, her weight was 30 kg in relation to her height being 5.4 ft and a bmi of 15.6 .
her thyroid function was normal , serum electrolytes were normal , her hemoglobin was 8 gm / dl . clinical depression was ruled out and a diagnosis of atypical anorexia nervosa was made ( according to icd-10 ) . the general health questionnaire ( ghq ) and the eating disorder examination questionnaire ( ede - q ) were administered .
nutritional rehabilitation was planned , where she was asked to maintain a dairy about her intake of food .
post sessions with the family , husband was involved in the therapeutic process and was asked to keep a watch on her purging behavior .
techniques of insight - oriented psychotherapy and cognitive behavioral therapy were structured to address the cognitive distortions . she was subsequently discharged and
her weight gain at the end of 1 month was 4 kg . at the end of 6 months , there was a weight gain of 15 kg . at the end of 1 year
, there was a relapse in symptoms with patient reported of decreased intake of food and purging tendencies .
mrs s symptoms remitted . at the end of 2 years , her weight was 55 kg with no fresh complaints .
though the cases of anorexia nervosa are reported greatly in the grey literatures of the western countries , the number of clinical cases in india is on the rise .
most cases are brought to clinical attention only when there are severe somatic complaints . in this case ,
mrs s was taken to the physician by her husband with symptoms of weight loss and amenorrhea .
multiple specialist opinions were taken to ascertain the cause of symptomatology . with no clear cut causal factor , the case as referred for psychiatric evaluation .
there were no other potentially fatal medical consequences as the case was referred at the earliest by the physician . by reporting the particular case ,
the authors call for the attention of general practitioners and other medical practitioners to be aware of the symptomatology of eating disorders as most patients would overtly express somatic conditions similar to the reported case
. such awareness would have called for an earlier psychiatric intervention and curbed other unnecessary investigations . 

the confidentiality of the identity of the patient has been ensured.the patient has been informed of the publication of the case.the case report is in the best interest of the community and to create awareness among mental and general health professionals.a copy of the article has been submitted to the ethical committee for clearance .
