Anxiety: Symptoms and Causes

Anxiety is a common and normal feeling, but when it becomes intense, chronic, and affects daily life, it can be classified as an anxiety disorder. Anxiety disorders are a group of mental health conditions that include Generalized Anxiety Disorder (GAD), Panic Disorder, Social Anxiety Disorder, and others. In this article, we will discuss the symptoms and causes of anxiety in more detail.

Anxiety Symptoms and Causes

Symptoms of Anxiety

Anxiety can present itself in various ways, and some common symptoms include:

  • Constant worry or fear: People with anxiety often experience excessive and persistent worry about everyday situations and events. This worry can be difficult to control and can interfere with daily activities.
  • Racing or repetitive thoughts: Some individuals with anxiety may experience repetitive thoughts, such as intrusive thoughts or worries, that they cannot stop or dismiss.
  • Physical symptoms: Anxiety can also cause physical symptoms such as sweating, shaking, heart palpitations, and digestive issues. These symptoms can be distressing and contribute to the overall feeling of anxiety.
  • Avoidance of certain situations or activities: People with anxiety may avoid certain situations or activities, such as public speaking or driving, due to fear or worry. This avoidance can limit their daily functioning and quality of life.
  • Difficulty sleeping or staying asleep: Anxiety can also affect sleep, causing difficulty falling or staying asleep, or waking up feeling exhausted.
  • Irritability or restlessness: Individuals with anxiety may also experience irritability or restlessness, making it difficult to relax or stay calm.

It is important to note that everyone experiences anxiety differently and some people may have unique symptoms. If anxiety is affecting daily life and causing distress, it is recommended to seek professional help.

Causes of Anxiety

Anxiety can be caused by a combination of factors, including:

  • Genetics: Anxiety can run in families and may be influenced by genes. Studies have shown that individuals with a family history of anxiety disorders are more likely to develop an anxiety disorder themselves.
  • Life experiences: Traumatic events, abuse, neglect, and other negative life experiences can increase the risk of developing anxiety. These experiences can affect the way the brain processes information and trigger anxiety symptoms.
  • Brain chemistry: Chemical imbalances in the brain can play a role in anxiety. Specifically, imbalances in neurotransmitters such as serotonin and GABA can contribute to anxiety.
  • Substance abuse: Substance abuse, particularly of stimulants, can lead to anxiety. Stimulants can cause an increase in heart rate, sweating, and other physical symptoms that can mimic anxiety.
  • Chronic medical conditions: Chronic illnesses, such as heart disease or diabetes, can increase the risk of anxiety. Chronic medical conditions can cause stress and worry, which can trigger or worsen anxiety symptoms.

Stress can also be a major contributor to anxiety. Stressful life events such as job loss, financial difficulties, relationship problems, and health issues can trigger or worsen anxiety symptoms. Chronic stress can lead to the development of an anxiety disorder.


Anxiety is a normal feeling that can become intense and affect daily life. The symptoms of anxiety can vary but include constant worry, physical symptoms, and avoidance of certain situations. Anxiety can be caused by a combination of factors including genetics, life experiences, brain chemistry, substance abuse, and chronic medical conditions. If anxiety is affecting daily life and causing distress, it is recommended to seek professional help. A mental health professional can help diagnose anxiety and develop a treatment plan, which may include therapy, medication, or a combination of both. With the right support and treatment, it is possible to manage anxiety and improve overall well-being.
