will an underactive thyroid cause weight gain?

Since the BMR in the patient with hypothyroidism (see Hypothyroidism brochure) is decreased, an underactive thyroid is generally associated with some weight gain. The weight gain is often greater in those individuals with more severe hypothyroidism.

Hypothyroidism (underactive thyroid) is a condition in which your thyroid gland doesn't produce enough of certain crucial hormones. Hypothyroidism may not cause noticeable symptoms in the early stages.

Overview. Hypothyroidism (underactive thyroid) is a condition in which your thyroid gland doesn't produce enough of certain crucial hormones. Hypothyroidism may not cause noticeable symptoms in the early stages.

Only about 10% of your total weight gain is likely due to the water and salt that your body keeps because of hypothyroidism. If extra weight is the only symptom left after thyroid medication brings your hormone levels back to normal, hypothyroidism probably isn't directly to blame for it.

Following thyroid surgery, patients often complain of weight gain, even when they have achieved biochemical euthyroidism. Studies examining this issue have found mixed results. Many of these studies have unclear/incomplete follow-up and are at high risk of selection bias (6–9).

An unexplained change in weight is one of the most common signs of a thyroid disorder. Weight gain may signal low levels of thyroid hormones, a condition called hypothyroidism. In contrast, if the thyroid produces more hormones than the body needs, you may lose weight unexpectedly. This is known as hyperthyroidism.

While it's not as common as people may think (or hope), thyroid conditions can certainly be a factor in weight gain. Your thyroid controls your metabolism, so when it's working slower than normal (hypothyroidism), it will inevitably lead to weight gain. "Unexplained weight gain is one symptom of this condition," Dr.

This also means that not producing enough thyroid hormone is usually associated with a low basal metabolic rate. Therefore, hypothyroidism (underactive thyroid) can cause weight gain. Your body isn't burning as much energy, which can lead to a calorie surplus.

Symptom: Weight Gain or Loss An unexplained change in weight is one of the most common signs of a thyroid disorder. Weight gain may signal low levels of thyroid hormones, a condition called hypothyroidism. In contrast, if the thyroid produces more hormones than the body needs, you may lose weight unexpectedly.

The hormones your thyroid gland releases help regulate your metabolism, or how efficiently your body burns food for energy. When your thyroid makes less of its hormones — as it does in hypothyroidism — your metabolism slows down. So you won't burn off calories as quickly and you'll gain weight.

It's also possible for you to gain weight if your dose of Synthroid isn't high enough for your body's needs. This is because if your thyroid hormone levels aren't high enough, your metabolism* may be slowed. And this might make it easier for you to gain weight.

Summary: Contrary to popular belief, effective treatment with levothyroxine (LT4) to restore normal thyroid hormone levels is not associated with clinically significant weight loss in most people. Decreased thyroid function, or hypothyroidism, is commonly associated with weight gain.

If your thyroid is underactive, a lack of treatment, or insufficient treatment, may make weight loss almost impossible, despite diet and exercise. And the longer it takes you to get diagnosed, the more weight you could gain.

A daily dose of levothyroxine (Levothroid, Levoxyl, Synthroid) will rev up your thyroid hormone production again, and with it, your metabolism. Once you're on the right dose, your weight should stabilize, and you shouldn't have any more trouble losing weight than anyone else.

Even mild cases of hypothyroidism may increase the risk of weight gain and obesity. People with the condition often report having a puffy face as well as excess weight around the stomach or other areas of the body.

A high level of TSH and a low level of T4 in the blood could mean you have an underactive thyroid. If your test results show raised TSH but normal T4, you may be at risk of developing an underactive thyroid in the future.

Not for weight loss Synthroid has a strong warning against using the hormone for weight loss, but it happens anyway. In some cases, doctors write a prescription to appease overweight patients who blame their extra weight on low thyroid levels — even when blood tests show levels are normal.
