Do you gain weight after a thyroidectomy?

Patients with hyperthyroidism frequently gain weight following thyroidectomy. This is related to a decrease in circulating thyroid hormone, which improves the weight-loss effects of higher thyroid hormones (4,5). Weight gain also occurs in patients with hypothyroidism who are treated with thyroxine.

Following surgery, your body needs time to adjust to these new conditions. So, even if you have excess thyroid tissue remaining after surgery, it will take time for this tissue to influence your metabolism before you start gaining weight again.

In addition, there are other factors that can affect your post-operative weight gain including:

The type of surgery you undergo affects how quickly you will regain your pre-surgery weight. For example, if you lose weight due to hyperthyroidism and then have a thyroidectomy, you will likely put some of this weight back on because the gland is no longer producing hormones that control appetite. If you need replacement therapy because your thyroid was too large or you had radioactive iodine administered, then you will probably remain underweight until you start taking thyroxine or radiation treatment ends. These factors also determine how far beyond your original weight you will be after surgery.

Age plays a role in how fast you will regain your pre-surgery weight.

Does parathyroid cause weight gain?

Parathyroid opathy and hyperparathyroidism are linked to weight gain. Concerns regarding weight gain following parathyroid surgery are normal but unjustified. It is a common misconception that undergoing parathyroid surgery and removing a parathyroid tumor promotes weight gain. In fact, patients with hyperparathyroidism often have reduced body mass due to impaired bone metabolism. When parathyroid hormone (PTH) levels return to normal after surgery, the body's new balance of calcium vs. phosphate leads to changes in weight.

Here is how parathyroid disease affects weight: PTH plays an important role in regulating blood calcium levels. High levels of PTH can cause bones to lose calcium, which leaves them lighter. Low levels of PTH can lead to bones taking up too much calcium, which can also leave them lighter. Patients with hyperparathyroidism usually have lower-than-normal bone mineral density (BMD) because their bodies are trying to restore calcium levels by drawing on bone reserves.

Following surgery to remove a parathyroid tumor, healthy glands will be found in about 95% of cases. In these people, parathyroid cancer was not part of the diagnosis; therefore, no surgery was performed for it. Most authors agree that the prevalence of cancer among patients with primary hyperparathyroidism is less than 1%.

Do you gain weight after parathyroid surgery?

Patients who undergo parathyroidectomy for hyperparathyroidism experience weight loss before the operation as well as post-operatively. However, they often regain some of their pre-operative weight once their hormone levels return to normal. For example, a patient who is 180 cm tall and weighs 70 kg (154 lb) will lose about 3 kg (6.6 lb) due to disease-related hypercalcemia before undergoing parathyroidectomy. After the operation, this person's calcium level should be corrected to prevent further weight loss and ensure that vital organs such as the heart are not affected by elevated calcium levels.

Following parathyroid surgery, patients may experience weight gain because:

1. The procedure removes part of the parathyroid gland which regulates blood calcium levels. As such, patients require more calcium in their diets to maintain healthy levels. Since most people don't consume enough calcium per day, they may need to take supplements or eat more dairy products and other calcium-rich foods to meet their needs.

2. Some patients may also experience muscle atrophy due to increased levels of calcium in the body.
