Hypothyroidism is a condition in which the thyroid gland is not able to produce enough thyroid hormone. Since the main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. Diabetes Mellitus (DM) is a clinical syndrome characterize by high blood glucose concentration resulting from defects in insulin secretion, insulin action or both. The main objectives of this study are: To find out the association between Hypothyroidism & D.M., to find out the anthropometric assessment and physiological status of hypothyroidism and diabetic patient, to find out the nutritional status of hypothyroidism and diabetic patient, to find out the biochemical status of hypothyroidism and diabetic patient. A total of 30 subjects were studied for the study. 10 subjects with Thyroid (Hypothyroidism) patient with Diabetic patient (sample-1), 10 subjects with Thyroid (Hypothyroidism) patient (sample-2) and 10 subjects with Diabetic patient (sample-3) from local area (Tamluk) of West Bengal. It is living standards survey focuses on only urban and rural community when collecting data, data were collected at the study location via face to face questionnaire method. Here all the subject that has been taken have type-2 diabetes, & thyroid disease. Here it is make sure that these persons do not have any other complication like kidney disease, hematological abnormalities, liver disease, albuminuria (300 mg/24 h). after the study it was found that the patients who are suffering from diabetes (sample-1) & compare their health status with the patient of thyroid dysfunction(sample-2) & found that there is a significant difference in T3, T4&TSH level. In this study the samples are also significantly differ in both Systolic & diastolic blood pressure, at the level of 0.001 & 0.05 respectively. There is also significant difference of pulse rate at the level of 0.05 between the three samples. In the study of nutritional status, it was found that, Carbohydrate consumption is higher in sample -1 (thyroid patient with diabetes patient) than sample -2 (thyroid patient)& sample -3 (diabetes patient), protein consumption is higher in sample -1 (thyroid patient with diabetes) than sample -2 (thyroid patient) & sample -3 (diabetes patient) and fat consumption is higher in sample -3 (diabetes patient) than sample -2 (thyroid patient) & sample -1 (thyroid patient with diabetes patient). From this study it was concluded that Thus, thyroid dysfunction was found to be more prevalent in diabetic subject in comparison to controls. Subclinical hypothyroidism was significantly more common than overt hypothyroidism and both overt & subclinical hypothyroidism were more common in diabetic females. There were enough hypothyroid cases (both asymptomatic and symptomatic) even through the sample size was small, to warrant a conclusion that routine testing of thyroid functions in all diabetics will be beneficial and should be recommended.
