Age may also be a factor. Though those of any age can develop this condition, it’s most often seen in those under 40.

Stress, pregnancy and smoking can also increase the risk of developing Graves’ disease. And if you have another autoimmune disorder, your chances of developing this condition are also elevated. For example, the Mayo Clinic says that those with type 1 diabetes and rheumatoid arthritis have a greater chance of developing Graves’ disease than those who don’t.

Symptoms and Risk Factors

There are a number of symptoms often associated with Graves’ disease. One well-known symptom is general mood instability. Because the thyroid hormone affects moods, those with Graves’ disease can become irritable and anxious. This can be frustrating for both the person affected and family members.

The thyroid is also a temperature regulator. As a result, those with Graves’ disease may become warm and sweat often. Their hands may shake, and they may experience an irregular heartbeat.  

Nearly one-third of those with Graves’ disease have Graves’ ophthalmopathy. According to the Mayo Clinic, “in Graves' ophthalmopathy, inflammation and other immune system events affect muscles and other tissues around your eyes.”  

This may cause the eyes to bulge out, almost with a bug-like look. Other ocular symptoms may include double vision or vision loss, eye puffiness, sensitivity to light and a feeling of pressure in the eyes.
