Diagnostic Tests for Overeating
Diagnostic Test list for Overeating:
The list of diagnostic tests
mentioned in various sources as
used in the diagnosis of Overeating
- Physical examination
- Measure body mass index (BMI) - i.e. weight in kg/(height in meters) squared.
- Calculate Waist-Hip ratio. Obese people with a high waist-hip ratio (over 1.0 in men and over 0.9 in women) have a significantly greater risk of diabetes mellitus, stroke, heart attacks and early death than equally obese people with lower waist-hip ratio
- Determine the distribution of body fat. If the obesity is predominantly abdominal, especially with a moon-shaped face, must consider Cushing's syndrome. Type 2 diabetes is also associated with abdominal obesity
- Blood pressure - e.g. may be high in diabetes, Cushing's syndrome or obesity; low in Addison's disease.
- Examine for signs of bulimia nervosa - e.g. cardiac arrhythmia, dental decay and swollen salivary glands due to vomiting and dehydration due to diuretic abuse.
- Examine for visual field defects and papilledema that may be present with pituitary or hypothalamic tumors
- Examine for signs of Graves disease including look for proptosis (forward displacement of the eyeball), thyroid enlargement, fine tremor, rapid pulse
- Examine for signs of Cushing's syndrome - e.g. thin skin, bruising,high blood pressure, stretch marks, proximal muscle weakness, acne, pigmentation, excess hair on face, frontal balding in males,moon face, buffalo hump, truncal obesity, fluid retention.
- Examine for signs of hypothyroidism - e.g. slow heart rate, slowed reflexes, coarse dry brittle hair, dry cool skin, goiter.
- Mental state examination - including appearance, behavior, rate and continuity of speech, mood, affect, thought content, evidence of any hallucinations or abnormal beliefs, orientation to time, place and person, attention and concentration, short-term memory, insight and judgement. This will help detect depression, anxiety and bipolar affective disorder (overeating and excessive appetite when in the manic phase).
- Blood tests
- Full blood count and ESR
- Electrolytes and renal function tests
- Thyroid function tests
- Fasting blood sugar +/- glucose tolerance test, if suspect diabetes
- Free cortisol, if suspect Cushing's syndrome
- Cortisol suppression test, if suspect Cushing's syndrome
- Plasma insulin, C- peptide or 72 hour fast with frequent blood sugar determinations, if suspect insulinoma
- Pregnancy test to rule out pregnancy as cause of cravings
- Cortisol, ACTH assay, Synacthen stimulation test, adrenal antibodies if suspect Addison's disease
- Urine tests
- Urine analysis to test for sugar
- 24 hour free cortisol, if suspect Cushing's syndrome
- Stool sample for microscopy looking for ovum and parasites - may diagnose tapeworms.
- Radiological investigations
- Pituitary gland CT scan or MRI - may detect pituitary tumor that may cause 60% of cases of Cushing's syndrome and also diagnose other brain tumors that may cause excessive appetite.
- Adrenal gland CT scan may detect adrenal tumors that may cause 15% of cases of Cushing's syndrome
