Anxiety is a normal reaction to stress and can be beneficial in some situations. It can alert us to dangers and help us prepare and pay attention. Anxiety disorders differ from normal feelings of nervousness or anxiousness and involve excessive fear or anxiety.
It forms a category of mental health diagnoses that lead to excessive nervousness, fear, apprehension, and worry
These disorders alter how a person processes emotions and behaves, also causing physical symptoms. Mild anxiety might be vague and unsettling, while severe anxiety may seriously affect day-to-day living.
It disorders affect 40 million people in the United States. It is the most common group of mental illnesses in the country. However, only 36.9 percent of people with an anxiety disorder receive treatment.
A mental health disorder characterised by feelings of worry, anxiety or fear that are strong enough to interfere with one’s daily activities.
When does anxiety need treatment?
While it can cause distress, it is not always a medical condition.
Treatment includes counselling or medication, including antidepressants.
When an individual faces potentially harmful or worrying triggers, feelings of anxiety are not only normal but necessary for survival.
Since the earliest days of humanity, the approach of predators and incoming danger sets off alarms in the body and allows evasive action. These alarms become noticeable in the form of a raised heartbeat, sweating, and increased sensitivity to surroundings.
The danger causes a rush of adrenalin, a hormone and chemical messenger in the brain, which in turn triggers these anxious reactions in a process called the “fight-or-flight response. This prepares humans to physically confront or flee any potential threats to safety.
For many people, running from larger animals and imminent danger is a less pressing concern than it would have been for early humans. Anxieties now revolve around work, money, family life, health, and other crucial issues that demand a person’s attention without necessarily requiring the ‘fight-or-flight’ reaction.
The nervous feeling before an important life event or during a difficult situation is a natural echo of the original ‘fight-or-flight’ reaction. It can still be essential to survival – anxiety about being hit by a car when crossing the street, for example, means that a person will instinctively look both ways to avoid danger.
The duration or severity of an anxious feeling can sometimes be out of proportion to the original trigger, or stressor. Physical symptoms, such as increased blood pressure and nausea, may also develop. These responses move beyond It into an anxiety disorder.
While a number of different diagnoses constitute anxiety disorders, the symptoms of a generalized anxiety disorder (GAD) will often include the following:
- restlessness, and a feeling of being “on-edge”
- uncontrollable feelings of worry
- increased irritability
- concentration difficulties
- sleep difficulties, such as problems in falling or staying asleep
While these symptoms might be normal to experience in daily life, people with GAD will experience them to persistent or extreme levels. GAD may present as vague, unsettling worry or more severe that disrupts day-to-day living.
