3 Anxiety and Irritability
Increased levels of thyroid hormone in the blood causes anxiety and irritability. If you are feeling anxious without any reason, it could be due to your thyroid gland.
4 Heat Intolerance
This is another important symptom. Patients who suffer from Graves’ disease fail to tolerate heat or rise in temperature and usually demonstrate increased sweating and perspiration, often in the palms of the hand.
5 Diarrhea and Frequent Bowel Movements
Patients sometimes complain of long-standing diarrhea which has no obvious cause. If your dietary and hygiene habits are good and your diarrhea returns frequently, Graves’s disease could be the reason.
