Ever wondered why you were trembling before your exam, or why your palms got sweaty before that job interview? These anxious feelings are a natural way for the body to prepare itself for an important event. You would have also noticed how you started to calm down once the event was under way; you started to breathe easier and your heart stopped thumping. Such an anxiety actually helps us perform better as it makes us more alert.

However, some people experience anxiety or anxiety attacks for no apparent reason. If you find it hard to control your worries and if these constant feelings of anxiety affect your ability to go about your daily activities, then it might be a case of an anxiety disorder. 

Here is a quick checklist that you could use to see if your anxiety is a disorder:

Everyone experiences feelings of anxiety, so it is difficult to say when it can be diagnosed as an anxiety disorder. If your feelings of worry and dread have a disabling effect on you over a period of time, you should seek advice from a mental health professional. There are many types of anxiety disorders but their most common symptoms are:

• Increased heart rate and heavy breathing
• Increased muscle tension
• Tightening sensation in the chest
• Unsubstantiated and growing worries, and restlessness
• Obsessing over needless things leading to compulsive behavior

If you have noticed these signs in a friend or family member, you should talk to them about their possible condition and advise them to meet a mental health professional.

The most common factors that cause anxiety disorders are:

• Family history: People who have a history of mental health issues in the family may usually have problems with anxiety. For instance, OCD can be passed down in a family.
• Stressful events: Stress at the workplace, loss of a loved one, or troubled relationships, can also trigger symptoms of anxiety.
• Health issues: Ailments such as thyroid problems, asthma, diabetes or a heart disease can also cause anxiety. People suffering from depression can also develop symptoms of anxiety disorders. For instance, someone who has been suffering from depression for a long period, may start to underperform at work. This can then lead to work-related stress which could trigger anxiety.
• Substance use: People who are heavy users of drugs, alcohol and other substances, develop anxiety problems when the effects of the substance begin to wear off (in withdrawal).
• Personality factors: Sometimes, people with certain personality traits such as perfectionists or people who like to be in control, develop anxiety-related issues.

Anxiety affects people in different ways leading to a variety of disorders. The most common forms of anxiety disorders are:

• Generalized Anxiety Disorder (GAD) 
  People suffering from GAD experience excessive anxiety and worry about various events and situations. They have difficulty in controlling anxiety and worry, along with restlessness and 'feeling keyed up or on edge' all the time. Such people are not worried about anything in particular and there is no specific trigger.
• Obsessive Compulsive Disorder (OCD)
  People with OCD have constant thoughts and fears that trigger anxiety. They relieve this anxiety by performing certain actions repetitively. For instance, a person with a fear of germs and contamination will repetitively wash his or her hands, and the vessels at home.
• Social phobia/Social anxiety disorder (SAD)
  People with social anxiety disorder fear social and performance-related situations where they may be subject to the scrutiny of others. They have an intense fear that something they do or say will lead to their humiliation or embarrassment. These people are unable to handle everyday situations such as making small talk or even eating in public.
• Specific phobias
  Phobias are unsubstantiated fears and people with phobias go to great lengths to avoid the object or situation that triggers their anxiety. Their fears could range from flying in airplanes, being in crowded places, to harmless things such as spiders and high-rise buildings.
• Post-Traumatic Stress Disorder (PTSD)
  Being part of or witnessing an extremely traumatic event such as accidents or an assault can later lead to PTSD. The person will have difficulty sleeping or relaxing due to constant flashbacks of the event.
• Panic disorder
  People with panic disorder suffer from panic attacks that are uncontrollable and include a range of physical symptoms such as dizziness, shortness of breath and excessive perspiration. During these episodes, they also report psychological symptoms (thoughts) like experiencing a sense of impending doom and feelings such as ‘I am going to die’ or ‘I will go crazy’. These attacks happen for no apparent reason, and the person then lives in constant fear of suffering another such episode.

Anxiety disorders can be overcome but one must not underestimate the seriousness of the problem. If you suffer from any of the above symptoms, it is best you seek professional advice and treatment. Anxiety disorders are treated through anxiety medication, counseling or a combination of the two.

If you have a family member or a friend who is suffering from anxiety disorders, your support can go a long way in reducing their distress. As with any sort of illness, the first thing you should do is to learn about the sufferer’s problem so that you can empathize with their condition. Dealing with people suffering from anxiety disorders requires a lot of patience, but they also need to be pushed and encouraged from time to time to face their stressors or fears so that they may overcome these fears. It is essential that you find the right balance for this.

There are many skills which you can learn in order to manage your anxiety. Positive thinking, stress management, leading a healthy lifestyle and relaxation are some of the common techniques that people use. Trying to manage anxiety by yourself can be challenging, especially if you are experiencing a lot of discomfort and unease. It’s always a good idea to reach out for professional advice in such cases.
