Psychiatric Diseases - Anxiety
Anxiety is a feeling of nervousness, apprehension, fear, or worry. Some fears and worries are justified, such as worry about a loved one or in anticipation of taking a quiz, test, or other examination. Problem anxiety interferes with the sufferer's ability to sleep or otherwise function. It is noteworthy that teenagers are particularly susceptible to having irritability as a symptom of a number of emotional problems, including anxiety. Anxiety may occur without a cause, or it may occur based on a real situation but may be out of proportion to what would normally be expected. Severe anxiety can have a serious impact on daily life.
Anxiety can be accompanied by a variety of physical symptoms. Most commonly, these symptoms are related to the heart, lungs, nervous, and gastrointestinal systems. You may have upset stomach, diarrhea, trouble breathing, feel as if you may faint or are having a heart attack.
