If an individual experiences an abrupt onset of intense fear or anxiety, he/she might be having a panic attack. The indications of a severe panic attack can somehow mimic a heart attack that can worsen anxiety or fear in some individuals. Recurring symptoms of a severe panic attack might indicate that the individual has a chronic anxiety disorder called as panic disorder. It is vital to discuss the symptoms of a severe panic attack with the doctor to ensure that proper treatment is provided.
Heart rate abnormalities
A panic attack can trigger the flight-or-fight response within the body, thus resulting to the release of various stimulatory chemicals in the bloodstream. Once this occurs, the heart muscle can be overstimulated which causes it to start beating abnormally fast. An increased heart rate can lead to the development of additional symptoms including dizziness or headache.
Headache or dizziness
Once an individual experiences a severe panic attack, the body perceives that it is under physical danger. The body releases chemicals that stimulate the central nervous system such as adrenaline which increases nerve signaling within the brain. These panic signals along with the changes in the heart and breathing rate can result to symptoms such as dizziness, headache or lightheadedness. It is important to note that these symptoms of a severe panic attack can cause the individual to feel unstable when attempting to stand or walk and can occur along with abnormal muscle shaking or trembling.
Breathing difficulty
The reaction triggered by a severe panic attack can result to an increase in the normal breathing rate. This occurs since the body perceives that it is in need of additional oxygen and energy to escape the physical threat. As a result, the individual starts to breathe faster than normal, resulting to a condition called hyperventilation. A severe panic attack can also result to breathing difficulty such as shortness of breath.
Chills or sweating
A severe panic attack can trigger the body to become abnormally cold or hot that can contribute to symptoms of excessive sweating or chills. The hands might feel clammy or damp and start to shake uncontrollably. Remember that these sensations usually occur along with heart or lung-related symptoms of a severe panic attack.
Changes in the mood or behavior
The individual can also experience a variety of changes in the mood or behavior. An individual feels irrationally anxious or might fear for his/her physical safety despite the lack of immediate danger.
A severe panic attack can trigger a sense of doom or detachment from the surroundings. The individual might also develop fear of impending death or start to feel as though he/she is losing complete control. These mood and behavioral changes during a severe panic attack can be frightening not only to the individual but also those around.
Stomach upset
If an individual experiences a severe panic attack, he/she can experience symptoms of stomach upset. Take note that these symptoms can include nausea or abdominal cramps and can be accompanied by the sensation of dryness or tightness inside the throat or mouth that can cause difficulty swallowing.
