The weight gain is often greater in those individuals with more severe hypothyroidism. However, the decrease in BMR due to hypothyroidism is usually much less dramatic than the marked increase seen in hyperthyroidism, leading to more modest alterations in weight due to the underactive thyroid. The cause of the weight gain in hypothyroid individuals is also complex, and not always related to excess fat accumulation. Most of the extra weight gained in hypothyroid individuals is due to excess accumulation of salt and water.
Massive weight gain is rarely associated with hypothyroidism. In general, pounds of body weight may be attributable to the thyroid, depending on the severity of the hypothyroidism.
Finally, if weight gain is the only symptom of hypothyroidism that is present, it is less likely that the weight gain is solely due to the thyroid. As in the treatment with hyperthyroidism, treatment of the abnormal state of hypothyroidism with thyroid hormone should result in a return of body weight to what it was before the hypothyroidism developed. However, since hypothyroidism usually develops over a long period of time, it is fairly common to find that there is no significant weight loss after successful treatment of hypothyroidism.
Again, if all of the other symptoms of hypothyroidism, with the exception of weight gain, are resolved with treatment with thyroid hormone, it is less likely that the weight gain is solely due to the thyroid. Once hypothyroidism has been treated and thyroid hormone levels have returned to the normal range of thyroid hormone, the ability to gain or lose weight is the same as in individuals who do not have thyroid problems.
Thyroid hormones have been used as a weight loss tool in the past. Many studies have shown that excess thyroid hormone treatment can help produce more weight loss than can be achieved by dieting alone.
However, once the excess thyroid hormone is stopped, the excess weight loss is usually regained. Furthermore, there may be significant negative consequences from the use of thyroid hormone to help with weight loss, such as the loss of muscle protein in addition to any loss of body fat.

It travels in the bloodstream in two types of packages, called lipoproteins: High-density lipoprotein HDL cholesterol is good for your heart. It helps remove cholesterol from your body and protects against heart disease.
Low-density lipoprotein LDL cholesterol is bad for your heart. If LDL cholesterol levels are too high, the cholesterol can clog arteries and contribute to heart disease, heart attacks, and strokes. Underactive or overactive thyroid The thyroid can produce too little or too many hormones sometimes.
A condition in which your thyroid is underactive is called hypothyroidism. You become tired, sluggish, cold, and achy.
Thyroid-Stimulating Hormone - elecciones2013.info
The production of T4 is regulated by thyroid stimulating hormone TSH which is secreted by the pituitary gland. T4 is measured in the blood as free T4 FT4. However, there is little information as to whether age or sex has any influence on this FT4: This is important, since management of the treatment of hypothyroidism or hyperthyroidism relies on getting both FT4 and TSH in the normal range.
The aim of this study was to examine the effect of age and sex on the relationship between blood measurements of FT4 and TSH. Hadlow NC et al.
