Yes, healthy diet and exercise. Living unhealthily causes excess hormones in your body which results in thyroid problems because you "metabolism" has to work hard. Eating a mainly vegetarian diet with meat infrequently is an excellent way to prevent thyroid problems. Also exercise is essential. Genetics is unfortunately a term used too often for issues that there isn't a clear answer form. You can be in control of your own health.
thats something you really need to consult your doctor about so they can make a medical plan that suits your specific thyroid problem.
prevention is not the same as medication....
