GAD can affect people both mentally and physically.1 The person’s worries seem out of proportion when compared with the actual likelihood of something bad happening, yet they find it difficult to control their feelings.2 If one worry is resolved, the person is likely to shift to worrying about something else.2
In addition to excessive worry, people with GAD may have symptoms such as difficulty concentrating, feeling on edge, becoming tired more easily, and feeling irritable.2 People with the disorder may also experience physical symptoms such as sweating, nausea, and shortness of breath.2
The severity of symptoms may fluctuate over time and are often worse during times of stress.3
