Causes for a high TSH level: 1 Hashimoto's thyroiditis: It is a condition where your body begins to attack its own thyroid gland, through an autoimmune process, which results in long-term and potentially permanent damage to your thyroid gland over time. 2 Iodine deficiency: Iodine is required for the production of the thyroid hormone in your body. Low iodine content in the diet will result in low circulating thyroid hormone in the serum. This may trigger a feedback loop that will result in an increase in the TSH level from your pituitary. 3 Obesity and metabolic damage: Obesity, weight gain, and metabolic damage may all potentially increase your TSH level and lead to hypothyroidism. Women with polycystic ovarian disease are at special risk. 4 Stress and increased cortisol: A high TSH level may also be due to stress and an increased cortisol level. A high cortisol level is positively correlated with TSH levels in the serum. Cortisol is considered our stress hormone that is released to help our body tolerate excessively stressful situations. 5 Thyroidectomy (partial or complete): Damage to or removal of your thyroid gland may increase TSH levels. 6 Drugs: Lithium, metformin, and other drugs are known to cause thyroid dysfunction.
