Low thyroid stimulating hormone levels are usually caused by hyperthyroidism, so if you have low thyroid stimulating hormone levels, you need to treat them promptly to avoid more severe symptoms of hyperthyroidism. At this stage, medication, surgery, iodine 131 and diet can be used. Low thyroid hormone levels can be treated with medications under the guidance of a clinician, such as methimazole and propylthiouracil. The liver and kidney functions should be checked regularly while taking the drugs. For younger patients with more severe symptoms, surgery can be performed, which is very effective. However, there is a risk of hypothyroidism after surgery, so it is also important to choose carefully. Iodine 131 treatment is one of the more effective methods of treating low thyroid hormone levels at this stage, but it requires a certain amount of financial resources and a certain level of physical fitness to be treated with this method. Low thyroid hormone levels consume a lot of energy, so it is important to get more protein and calories. It is important to eat more eggs, milk, lean meat, fresh vegetables and fruits, and not to eat stimulating foods such as strong tea and coffee that may increase the symptoms and are not conducive to recovery from the disease.
