What is anxiety?
Anxiety is a term that can refer to a symptom, a personality trait or a condition. Anxiety is an adaptative mechanism that the brain uses to alert us when facing problems or complicated events. It is a natural and adaptative response, as it is helpful to keep us alive in dangerous situations. Moderate levels of anxiety can keep us focused and ready to tackle any future challenge.
However, the anxiety sometimes exceeds the moderate level, even when there is no real risk or danger. If this happens, the person can feel overwhelmed, paralysed, tense, worried, and vulnerable, which leads to further physical and mental problems.
Anxiety is considered a mental health condition when it is present on inappropriate occasions, when there is no real reason behind it, and when it impacts the everyday life of the person affected.
Rethink Mental Illness explains that “your brain responds to a threat or danger by releasing stress hormones such as adrenaline and cortisol. Even if the danger is not real, these hormones cause the physical symptoms of anxiety. Once the threatening situation has stopped, your body will usually return to normal”.
It can be present in different types of anxiety, each of them showing different symptoms.
Types of anxiety
There are several disorders included within the anxiety disorder. The most common ones are:
The person suffers regular crises or panic attacks. Anxiety in this disorder is extremely high, and the symptoms are so intense that it is common to feel that you will die. There is no specific trigger, and the person can even develop a fear of having panic attacks in the future.
The NHS advises that if you suffer sudden, intense anxiety and fear, it might be the symptoms of a panic attack. It can also be symptoms of a racing heartbeat, feeling that you are losing control, shortness of breath or breathing very quickly, sweating, trembling or shaking, and feeling faint.
Phobias are irrational and persistent fear of a specific object, animal, situation, event, etc. The fear can be focused on anything, but it is common phobias to insects, blood, flying, or height.
Obsessive-compulsive disorder (OCD)
Obsessive-compulsive disorder (OCD) is characterised by intrusive and repetitive thoughts that generate high anxiety levels, followed by compulsions performed to reduce that anxiety. The thoughts and compulsions are irrational, and the person is aware; however, the brain is fixated and stuck in this circle of obsession-compulsion.
Traumas and Post-traumatic stress disorder (PTSD)
Post-traumatic stress disorder (PTSD) is caused by a traumatic event that has impacted the sufferer emotionally. The type of trauma responsible for PTSD can be anything, and wars or rapes cause some common traumas.
The symptoms include recurrent memories of the event, extreme vigilance, loss of interest in daily activities that once were pleasant.

The causes of the anxiety disorders are not clear, and in some patients, they will remain unknown. In some other cases, it is possible to spot the root of the problem and discover the anxiety triggers. Some causes of anxiety are:
- Genes: it is possible to inherit the predisposition to develop anxiety from our parents. However, this mechanism is unknown, and much more research is needed to clarify genetics’ impact on anxiety.
- Drugs: some illegal drugs such as LSD, ectasis, amphetamines, or coffee can prompt anxiety.
- Environment: some difficulties or situations in life and certain events can trigger anxiety. Some examples can be getting pregnant, career problems, relationship issues, the loss of someone, etc.
- Traumas: traumatic events like an accident or a terrorist attack can also be the cause of anxiety. The symptoms can resolve within time, or they can end up in post-traumatic stress disorder.
People with anxiety can develop a range of mental or physical problems. It is important to recognise them, as some of the symptoms can be signs of an illness.
The mental symptoms can include constant worries, tiredness, agitation, attention problems or altered sleep. Anxiety can also lead to physical issues such as breathing difficulties, excessive sweating, tachycardia, headache, indigestion, dizziness, trembling, etc.
In order to prevent anxiety, it Is helpful to have a healthy lifestyle, eating healthy, sleeping correctly, and working out regularly. It is also essential to avoid the known triggers of anxiety and reduce or eliminate illegal drugs or coffee consumption.
Additionally, relaxation techniques, such as mindfulness, can be beneficial to keep a quiet and peaceful mind.
To diagnose a patient, it is recommendable to rule out any systemic illness. For doing so, it is necessary to check the physical symptoms, the mental history, the medical history of the patient and family, and the use of drugs or caffeine.
It is also relevant to check any other illness that can cause an anxiety disorder as a consequence.

Anxiety is a treatable condition. It has been proven that medication and psychotherapy can help to reduce or recover from anxiety.
Medication doesn’t cure the condition, but it can help to manage some symptoms of anxiety. There are different options, and you can discuss with your GP what is the best for you.
Antidepressants: as the National Institute of Mental Health explains, the most common medication used for anxiety disorders are anti-anxiety drugs (such as benzodiazepines), antidepressants, and beta-blockers.
The other treatment that proved successful is therapy, more specifically cognitive-behavioural therapy (CBT). CBT works well because it focuses on making the person aware of the type of thoughts, usually irrational, of their fears, challenging those thoughts and substitute them for other more realistic.
