Generalized Anxiety Disorder | Symptoms


How do I know if I have GAD?

Most people worry from time to time, and these occasional worries are normal. They don't mean that you have GAD. If you have GAD, you worry so much that it interferes with your day-to-day life, and you feel tense and worried more days than not. Other signs of GAD include the following:

  • Trouble falling or staying asleep
  • Muscle tension
  • Irritability
  • Trouble concentrating
  • Getting tired easily
  • Restlessness, or feeling "keyed up" or on edge
  • Trembling
  • Shortness of breath
  • Fast heartbeat
  • Dry mouth
  • Dizziness
  • Nausea

If you feel tense most of the time and have some of these symptoms, talk to your doctor. Your doctor will probably examine you and ask some questions to make sure that something else isn't causing your symptoms. Sometimes certain kinds of medicine may cause GAD. You could also have these symptoms if your thyroid gland is too active, or if you are depressed. However, if your doctor doesn't find any other reason for your symptoms, you may need to be treated for GAD.
