Hello,
Welcome to Health Care Magic. I read carefully your query and I understand your concern.
I see the description of your weight problem and I understand the suspicion on having thyroid problem correlated with history family, the under function of thyroid gland begin with fatigue and unexplained weight gain and go on with constipation, dry skin and elevated lipid blood profile. If you have these symptom you should do thyroid hormonal blood test to determine if you have hypothyroidism, the hormonal blood test needed for that are TSH, T3 and T4. If you will have TSH high from the normal range and T4, T3 at low level from the normal range these is the prove that you have hypothyroidism and you need to treat it and monitor the treatment in good way by an endocrinologist.
I recommend you to have thyroid blood tests hormone and blood lipid profile and take an appointment with the endocrinologist of your town.
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Kind regard,

Hello,

Thank you for your question and welcome to Health Care Magic. I understand your concern.

First of all I would like to ask you if you have any other sign or symptom beside difficulty in loosing weight, such as dry skin, your hands and feet cold all the time, thinning hair, fatigue, trouble losing weight, mild depression, poor concentration and memory, constipation, and more? The above mentioned symptoms may be triggered by subclinical hypothyroidism.
It is true that weight problems could be related with thyroid hormone deficiency. Hypothyroidism slows down the metabolism and consequently may cause weight gain.
With such a presentation on my clinic, in addition to your family history of having thyroid disorders, I would like to perform some blood tests in order to determine if you have thyroid hormone deficiency and its etiology.
The blood tests should include Total Thyroxine (T4), Thyroid Stimulating Hormone (TSH), Free Thyroxine Index, Free T3, Thyroglobulin Antibody and Thyroid Peroxidase Antibodies (anti TPO).
Beside thyroid function tests, I would like to perform also a lipid profile test, and blood sugar.
After evaluating these blood tests, I would be more helpful in giving you a hand on solving your problem.

Hope I answered to your question. For further concerns or follow up questions feel free to ask again.

Kind Regards,
Dr. Ina
