Anxiety is a feeling of unease, such as worry or fear, that can be mild or severe. Anxiety disorders are psychological conditions that involve excessive anxiety and fear. These disorders can affect a person’s ability to function in daily life.
The most common types of anxiety disorders are: generalized anxiety disorder (GAD), panic disorder, agoraphobia, social anxiety disorder (SAD), and specific phobias. GAD is characterized by chronic and exaggerated worry about everyday things such as health, work, or money. Panic disorder is characterized by recurrent and unexpected panic attacks, which are sudden periods of intense fear that may include palpitations, sweating, shaking, shortness of breath, and dizziness. Agoraphobia is an intense fear of being in situations where escape might be difficult or help would not be available if needed (such as being in an airplane or mall). SAD is marked by a persistent fear of one or more social situations in which a person may feel embarrassed, judged, rejected or fearful of acting improperly. Specific phobias are intense fears about specific objects or situations (such as flying or heights).
Anxiety disorders can have physical symptoms including: rapid heart rate; sweating;.
Cardiovascular system. Anxiety disorders can cause rapid heart rate, palpitations, and chest pain
The cardiovascular system is the body system that supplies blood to the body tissues. It includes the heart, which is a muscle that pumps blood, and the blood vessels, which are tubes that carry blood to and from the heart.
Anxiety disorders can cause rapid heart rate, palpitations, and chest pain. These symptoms are caused by an increase in adrenaline in the body. Adrenaline is a hormone that is released by the adrenal glands in response to stress. It causes the heart to beat faster and increases blood flow to the muscles so that they can be ready for action.
In some people, anxiety can also cause dizziness, lightheadedness, or fainting due to a drop in blood pressure. This happens because adrenaline causes narrowing of the arteries (vasoconstriction), which decreases blood flow to the brain.
Excretory and digestive systems. Anxiety also affects your excretory and digestive systems
Anxiety can have a number of different effects on your excretory and digestive systems. For example, you may experience an increase in urinary frequency or urgency, or you may have difficulty having a bowel movement. Some people also report feeling nauseated or vomiting when they are anxious.
Your digestive system may also be affected by anxiety in other ways. You may find that you have trouble digesting food, or that you experience heartburn or indigestion more frequently when you are anxious. Some people also report feeling bloated or gassy when they are anxious.
If you are experiencing any of these symptoms, it is important to talk to your doctor about them. While they are usually not serious, they can be very uncomfortable and disruptive to your life.
Respiratory system
The nose is responsible for filtering air and providing moisture to the airways. The mouth provides a passageway for air to enter the lungs. The lungs are where gas exchange takes place. Oxygen enters the lungs and diffuses into the blood where it is then transported to all of the cells in the body. Carbon dioxide enters.
