Hello doctor,

Four months before I found that I have thyroid with high TSH 18. Then I put off some weight and did morning walk and running, then it decreases to 14. Now I left the exercise because I met with an accident. Now I have done my test again it was 18 again. Now I consulted the doctor but he said that I have to take medicines lifelong. It was really shocking for me and he prescribed me Thyrox 50 mg and Pure D3 60000 iu for four weeks and Rabeprazole 20 mg. But I am nervous and confused about taking this drug because I read somewhere that once you started taking this drug it will replace your thyroid hormones. Then you have to take the medicines life long.

My weight is 80 kg, BP 110/180 mmHg, T3-0.98, T4-7.62 and TSH 15.98. Now kindly suggest me what should I do? Is it necessary to take the drug or is there any alternative? Please help.

Welcome to

First of all, you must have to understand the problem. You are suffering from medical condition called hypothyroidism. In this condition, the thyroid hormone production decreases. Thyroid hormone is necessary for the metabolism of the body and in the absence of this hormone body metabolic rate reduces and the person starts gaining weight. When thyroxine hormone decreases, TSH (thyroid-stimulating hormone) increases which trigger the thyroid gland to produce more thyroid hormone (T3, T4), and raised TSH level in the blood is a diagnostic factor, this is raised in your case.

Management: We have to give thyroid hormone preparation in the form of thyroxine which comes under various brand names like Thyrox and this is necessary for body metabolism. Otherwise, you will have to suffer from some other medical problems, so it is advisable to continue this medicine as advised by your doctor until your TSH level become normal. Then you can again consult your treating doctor or us for further plans until then you must take it. Frankly speaking, there is no alternative to this.

Here I noticed that your BP (blood pressure) is 110/180 mmHg. It is surprising that the diastolic is more than systolic. I think there is some typing error so again check your BP and tell, as this is suggestive of that you are hypertensive too, so you must start some anti-hypertensive medications. Rabeprazole is medicine for hyper-acidity.
