Graves' disease Complications

Graves' disease Complications
Any time your body produces too much thyroid hormone, because of Graves' disease or another cause, it can lead to a number of complications:

Heart problems. Some of the most serious complications of hyperthyroidism involve the heart. These include a rapid heart rate, a heart rhythm disorder called atrial fibrillation and congestive heart failure — a condition in which your heart can't circulate enough blood to meet your body's needs. These complications are generally reversible with appropriate treatment.

Brittle bones. Untreated hyperthyroidism can also lead to weak, brittle bones (osteoporosis). The strength of your bones depends, in part, on the amount of calcium and other minerals they contain. Too much thyroid hormone interferes with your body's ability to incorporate calcium into your bones.

Thyrotoxic crisis. Hyperthyroidism also places you at risk of thyrotoxic crisis — a sudden intensification of your signs and symptoms, leading to a fever, a rapid pulse and even delirium. This complication is rare, but if it occurs, seek immediate medical care.
