What are the causes of high thyroid-stimulating hormone (TSH)?
Elevated thyroid-stimulating hormone (TSH) levels are generally caused by factors such as improper diet, unhealthy lifestyle habits, stress, hypothyroidism, or pituitary adenoma. It is recommended to seek timely medical attention and receive symptomatic treatment under the guidance of a qualified physician. Specific causes are analyzed as follows:
1. Improper Diet
Long-term dietary imbalance leading to insufficient or excessive iodine intake may affect thyroid function and result in elevated TSH levels. Maintaining a balanced diet with scientifically appropriate food combinations is essential.
2. Unhealthy Lifestyle Habits
Poor lifestyle habits such as chronic sleep deprivation, overexertion, and high mental stress may lead to endocrine disorders, affecting thyroid function and causing increased TSH levels. It is important to maintain regular sleep patterns, get adequate rest, and avoid excessive fatigue.
3. Stress State
Remaining in prolonged states of psychological tension or exposed to external stressors may disrupt the balance of the endocrine system, resulting in elevated TSH levels. Appropriate stress management is necessary to minimize the physical impact of chronic stress.
4. Hypothyroidism
Hypothyroidism may be caused by poor dietary habits, medication effects, bacterial infections, or other factors. Decreased thyroid hormone levels reduce the inhibitory feedback on the pituitary gland, leading to elevated TSH levels. This condition is often accompanied by symptoms such as fatigue and cold intolerance. Treatment may include medications such as levothyroxine sodium tablets, hydrocortisone tablets, or thyroid extract tablets, as prescribed by a doctor.
5. Pituitary Adenoma
Pituitary adenomas are usually associated with genetic factors, exposure to chemical irritants, or bacterial infections. These tumors may oversecrete TSH, causing abnormally high TSH levels, often accompanied by symptoms such as headaches and blurred vision. Treatment may include medications such as octreotide acetate injection, mifepristone capsules, or cyproheptadine hydrochloride tablets, as directed by a physician.
Maintaining healthy eating habits, optimizing dietary structure, appropriately managing psychological stress, and ensuring sufficient rest are important for overall thyroid health.
