Anxiety, stress, and tension

Alternative names:

feeling uptight; jittery; stress; tension

Definition:

Stress is physical, mental, or emotional strain or tension. Tension is mental or emotional strain, suspense, anxiety, or excitement. Anxiety is a reaction to a real or imagined threat, a general feeling of uneasiness or dread.

Considerations:

Stress is not a disease and is a normal part of everyone's life. Stress is not necessarily good or bad; however, reactions to stress can vary considerably, and some of these reactions are undesirable. The most frequent undesirable reaction is anxiety.

Anxiety is often accompanied by twitching or trembling, muscle tension, headaches, sweating, irritability, fatigue, nightmares, memory problems, sexual impotence, sleeplessness, dry mouth, or difficulty swallowing.

The degree of anxiety is much more a function of the individual than the degree of stress. The risk of anxiety increases with stress, a family history of neurosis, fatigue or overwork, or the recurrence of situations that have been previously stressful or harmful.

Insomnia and an inability to concentrate are common symptoms of anxiety which can lead to a vicious cycle that makes the problem worse. The symptoms are effects, not causes. Focusing on the insomnia or on the lack of concentration as the problem is not the solution.

Common causes:

• actual danger
• physical and emotional stress
• grief (such as from death of a loved one or loss of a job)
• drugs including caffeine, cold remedies (Cough/Cold Combinations - oral), sympathomimetics, decongestants (Antihistamines and Decongestants - oral), bronchodilators, tricyclic antidepressants, and thyroid supplements
• withdrawal from drugs
• poor diet
• hyperventilation syndrome
• hyperthyroidism

Furthermore, the causes may vary based on age and gender of the affected person, as well as on the specific characteristics of the symptom such as location, quality, time course, aggravating factors, relieving factors, and associated complaints.
