Hypothyroidism, underactive thyroid or slow thyroid is a hormonal problem in which the thyroid gland, which produces thyroid hormones, reduces its activity so it produces less of them. These hormones are mainly responsible for growth and regulate the body's metabolism. Therefore, one of the main symptoms and problems of this disease is weight gain and the difficulty of controlling it.

As we know how complicated it can be, in we give you a series of tips that will help you if you are wondering how to lose weight if I have hypothyroidism. Take note of them and talk to your doctor before putting them into practice
What is the relationship between hypothyroidism and weight gain
According to Mayo Clinic, the main symptoms of hypothyroidism are:
- Weight gain
- Dry skin
- Swollen face
- Fatigue
- Increased sensitivity to cold
- Muscle weakness
- Constipation
- Reduced heart rate
- Hoarseness
- High LDL cholesterol level

In addition, according to this same clinic, hypothyroidism also produces many more problems, such as enlargement of the heart, goiter problems and it has also been shown that hypothyroidism affects fertility, among many more aspects. However, in this article we focus on weight gain that is really difficult to control, since it is one of the main problems that affect those who suffer from this thyroid problem, both physically and psychologically.
Focusing now on the relationship between hypothyroidism and weight gain, according to the American Thyroid Association, this is that basal metabolism is decreased by the lack of thyroid hormone and the body works much slower when it comes to metabolizing or processing nutrients and other substances. This produces a clear tendency to weight gain, which can range from mild to severe depending on the type of hypothyroid, since the body begins to store fats, salts and liquids very easily.
That is why many people who suffer from this condition wonder how to lose weight having hypothyroidism and go to their doctors to look for the solution and seek additional advice to achieve it. For this reason, in the next few lines we will try to solve this doubt in the clearest possible way.
How much weight can I lose when I treat hypothyroidism
If you're wondering how much weight you can lose if you have hypothyroidism, you'll be interested to know that the American Thyroid Association actually has weight gain associated with an underactive thyroid is between 2.5 kg and 5 kg and that this condition actually affects salt and water retention more than fat retention. Therefore, when it is possible to regulate thyroid hormone levels and, especially if you take care of your diet, it is possible to recover the weight before the onset of hypothyroidism, losing a maximum of about 5 kg, generally. Keep in mind that it will cost you less to lose weight if you have subclinical hypothyroidism, the mildest, than if you have one of its most severe forms.
If there is still significant overweight or even obesity after this treatment, it is clear that the problem of increased volume and weight is not only due to this thyroid condition. So, the doctor will have to continue investigating in each case the possible causes, such as a sedentary lifestyle, an unbalanced diet or other diseases related to basal metabolism.

Is thyroid hormone treatment really effective for weight loss if I have hypothyroidism? This is what many people with this problem of slow or underactive thyroid wonder having ever heard that when treated directly with the thyroid hormone that they lack, the body can rebalance and lose weight.
According to the American Thyroid Association, doctors long ago recommended this type of treatment as effective. It was about giving a high dose of this hormone to be able to get the body to use it and as a result the levels were equalized and weight was lost. However, it is not a treatment that can be done for life, since it affects more aspects such as the loss of muscle mass, and it was shown that once this hormone was finished and stopped being used, the patient recovers the lost weight, which is known as the rebound effect. Thus, today it is not considered a good option to lose weight with hypothyroidism.
