Anxiety is a feeling of the unpleasant state of internal unrest, often with neural behaviors such as back and forth, physical complaints, and rumors. These are the thematic unpleasant feelings of intimidation on anticipated events, such as the sense of impending death. Anxiety is not the same as fear, which is a reaction to real or perceived immediate hazards, while anxiety involves the expectation of future threat. Anxiety is a feeling of restlessness and anxiety, usually generalized and unforeseen as an exaggeration for a situation which is only seen as a menstrual cycle. It often happens with problems in muscular tension, discomfort, fatigue, and concentration. Anxiety may be appropriate, but when experienced regularly, a person may be suffering from anxiety disorders.
People experiencing anxiety can withdraw from those situations which have provoked anxiety in the past. There are different types of concerns. Existential anxiety may occur when someone encounters anger, an existential crisis or nihilistic feelings. People can also face mathematical anxiety, physical anxiety, stage fear or test anxiety. Social anxiety increases when people are unaware of there surroundings. The stress hormone released in the worrisome situation has an effect on bowel function and can reveal physical symptoms that can contribute or enhance IBS. Anxiety is often experienced by people with obsessive-compulsive disorder and there is a strong presence in panic disorder. The very first step in handling the person with anxiety involves evaluating the possible presence of an underlying medical reason, which is necessary to determine the correct treatment. Symptoms of anxiety can be masks of an organic disease or may appear as a result of a medical disorder or related to it.
Worry can be either a short-term "state" or long term "symptom". While the characteristic anxiety represents concern about future events, anxiety disorder is a group of mental disorders that are characterized by feelings of anxiety and fear. Anxiety disorder is partially genetic, twin studies suggest a 30-40% genetic effect on individual differences in anxiety. Environmental factors are also important. Twin studies show that individual-specific environments have a major impact on anxiety, whereas shared environmental effects (similarly the environment affecting twins) are operated during childhood but during adolescence falls. Exclusively measured 'environments' associated with anxiety include child abuse, family history of mental health disorders, and poverty. Anxiety is also associated with the use of drugs, including alcohol, caffeine, and benzodiazepines (which are often prescribed to treat anxiety).
Anxiety disorder often occurs with other mental health disorders, especially major depressive disorder, bipolar disorder, eating disorders or some personality disorders. It also usually occurs with personality traits like neuroticism. This co-occurrence is seen partly due to the shared genetic and environmental impact between these symptoms and anxiety.
