INTRODUCTION:Disease diagnosis isa very complex and challenging task. To identify the disease on correct timeand it helps to give the proper treatment. In earlier days disease are diagnoseby the symptoms. But now doctors are diagnose the disease by variousintelligent systems. Thyroid is the most common disease for human being; it isnot a deadly disease. Thyroid is a butterfly shaped gland that isplaced on the bottom of the neck. Thyroid glandproduces over or under production of thyroid hormones, triiodothyronine (T3) andlevothyroxine (T4).
T3 and T4 are controlled by thyroid stimulating hormone (TSH)which is produce from brain. Two types of thyroid disease are hypothyroidism andhyperthyroidism. Hypothyroidism is underactive thyroid it is the reason forthyroid gland can’t produce enough thyroid hormones and hyperthyroidism isoveractive thyroid it is the reason for thyroid gland can produce more thyroidhormone. Hypothyroid symptoms include weightgain, constipation, depression, slowed heart rate, fatigue, dry skin, puffface, muscle weakness, thinning hair and hyperthyroid symptoms include weightloss, irregular heartbeat, difficulty sleeping, nervousness, hair loss,shortness of breath. People taking the right doseof thyroid medication and have normal thyroid levels, but still suffering fromhypothyroidism.
Diagnose the subtypes of hypothyroidism is necessary togive the accurate result for the patients. TSH levels are high and T4 and T3 levels are low means overt (primary)hypothyroidism. Elevated TSH levels and normal T4 levels arecalled subclinical hypothyroidism. Normal TSH levels and low T4 levels arecalled central hypothyroidism. Data mining classification can beused to diagnose the subtype’s hypothyroid disease in an efficient way. Thispaper proposes to analyze the various classification algorithms which are usedto diagnose the accurate result of hypothyroid and to evaluate theirefficiency, Precision, and Error-Rate.
Reversetriiodothyronine (Rt3) is measured by blood test. Liver can constantly convertthe T4 hormone to RT3. It means 40% of T4 goes to T3 and 20% of T4 goes to RT3.
To calculate the RT3 ratio FT3 and RT3 levels are essential. If the ratio is greaterthan 20 means no problem, otherwise it makes RT3 problem.Basal body temperatureis used to diagnose the hypothyroid disease. Take the body temperature in fourconsecutive days using mercury thermometer. If the body temperature is lessthan 36.5 degree Celsius means it indicate hypothyroidism and TSH level is comeback as 2.
