5. Increased appetite
If you notice that you have an insatiable hunger, that no matter how much you eat, you are still hungry, it could be because you are experiencing issues with your thyroid. Namely, you might be suffering from hyperthyroidism or an overactive thyroid. When the thyroid is overactive, it produces heightened levels of hormones, which could impact your metabolism.
It could speed up your metabolism, which would end up making you feel more hungry than you usually do. And, though you are more hungry than normal, you probably won’t notice your increased desire to eat affecting your waistline.
That’s because, as mentioned, an overproduction of thyroid hormones increases the metabolism, which means that your body breaks down the food that you are eating more rapidly. If you are eating more than usual and you aren’t gaining weight, there is a chance that you are suffering from an overactive thyroid.
