Thyroid stimulating hormone, or TSH, is produced by the pituitary gland to stimulate the thyroid. The levels of TSH can indicate how well the thyroid is functioning. High levels of TSH can indicate an underactive thyroid, which needs more TSH to become properly stimulated. Low levels of TSH can indicate an overactive thyroid, called hyperthyroidism. While medications can treat a thyroid problem directly, you may prefer to take a holistic approach to naturally raise your TSH levels.
Talk to your doctor about decreasing or discontinuing any medications which may be affecting your thyroid. Medications for high TSH can cause artificially low TSH levels on blood tests; by adjusting the dose or stopping the medication, TSH levels will naturally rise.
Limit your intake of foods containing iodine and avoid supplements that contain this element. You may also add foods which are shown to suppress thyroid function and raise TSH. Cruciferous vegetables such as cabbage, broccoli, cauliflower and kale can decrease the effects of hyperthyroidism and elevate TSH levels.
Increase your oestrogen levels by taking a soy isoflavone supplement or increasing the number of soy-based foods in your diet. Elevated oestrogen levels, particularly during pregnancy, have been linked to elevated TSH levels.
