How does thyroid cancer cause weakness in the legs?

Thyroid cancer is a malignant tumor that originates from the thyroid follicular epithelium or parafollicular cells. There are many reasons for leg weakness, mainly surgical injury, hypothyroidism, cervical spondylosis, and thyroid cancer metastasis. It is recommended to seek medical attention in time and choose the appropriate treatment method according to the condition.

1. Surgical injury: Nerve damage during surgery may cause weakness in the legs. Functional exercises should be performed in time, and nerve nutrition drugs such as methylcobalamin tablets can also be used, which can generally recover gradually;

2. Hypothyroidism: After thyroid cancer surgery, due to surgical resection and postoperative medication, the patient may have insufficient thyroid hormone, hypothyroidism, and decreased metabolic rate, resulting in weakness in the legs. You can complete blood routine and thyroid function tests to clarify the condition, and take oral levothyroxine sodium tablets under the guidance of a doctor to supplement the lack of thyroid hormone;

3. Cervical spondylosis: After thyroid cancer surgery, bowing your head for a long time may lead to cervical spondylosis, with symptoms such as cervical pain and dizziness. If the nerves are compressed, it may cause weakness in the legs. You can complete a cervical MRI examination, and you can relieve it through physical therapy, acupuncture, etc. At the same time, pay attention to avoid bowing your head for a long time;

4. Metastasis of thyroid cancer: If thyroid cancer metastasizes and invades the bones or muscles of the human body, it will cause weakness in the legs. A detailed examination is needed to clarify the condition. The tumor can be removed surgically, and local radiotherapy and chemotherapy can be performed to inhibit the growth of cancer cells.

Patients are advised to take a rest and avoid staying up late or overwork. In terms of diet, they should eat more foods rich in vitamins and proteins, such as tomatoes, eggs, milk, etc. They can also eat some nuts such as walnuts and peanuts to supplement nutrition.
