It is common for most of us to get anxious, nervous, or restless about an event or activity. However, if this happens on a regular basis, it could be possible that one is suffering from an anxiety disorder. An anxiety disorder involves more than just a few worries or fears about something. The nervousness and anxiety will be frequent and last longer. In an anxiety disorder, the anxiousness does not go away in a few minutes, it stays as well as keeps coming back. Some of the examples of an anxiety disorder include agoraphobia, generalized anxiety disorder, panic disorder, separation anxiety disorder, substance induced anxiety disorder, and social anxiety disorder.

Heart-related problems
If you have seen someone have a panic attack or have had one yourself, you will be aware that the hands get clammy, you start breaking out cold sweats, and your heart starts to pound loudly. However, in some cases, a heart problem can also be the reasons for your anxiety or panic attacks. A person with a general anxiety disorder and a cardiovascular problem has higher chances of having an anxiety attack.

Abuse of alcohol and narcotic substances
Alcohol and substance abuse is strongly associated with anxiety and panic. An anxiety attack can easily be triggered if you are consuming large amounts of alcohol or narcotic substances. Research has shown that people who have anxiety try to indulge in alcohol and narcotic substances to calm themselves. This provides them temporary relief but can be harmful for them in the long run. The chances of a person with anxiety indulging in alcohol and narcotic substances is two to three times higher than that of a person without it. A person with social anxiety can face deeper symptoms if they indulge in alcohol or narcotic substances. No matter what the causing factor is, a combination of anxiety, alcohol, and narcotic substances can be fatal.

Caffeine
A caffeine intoxication is not a direct cause of an anxiety disorder, but it is one that dwells into anxiety over time. A caffeinated drink has the ability to stimulate anxious behavior in a person, if consumed on a regular basis the drink can also cause an anxiety disorder. Caffeine usually has a jittery effect on your body, which is similar to the feelings you have while witnessing a frightening event. Caffeine is known to trigger a “fight or flight” response, which is why you are reminded of a frightening event. Most studies have shown that consuming a heavily caffeinated drink can not only worsen the anxiety but also trigger an anxiety attack. Too many cups of strong coffee also hold the potential to make you nervous, moody, and restless—all triggers of anxiety.

Medications and supplements
There are a few medications that have anxiety, panic as their side effects. An overdose of such medications can cause an anxiety disorder. The prescribed medications that you must be careful about are thyroid and asthma medication as well as over the counter decongestants and cold medications. Discontinuing a certain anxiety medication all of a sudden can also be a reason for the anxiety to come back twice as strong. Supplements are also a type of medication that are known to cause anxiety in people. Weight-loss supplements are at the top of the pile of anxiety-causing supplements. The main side effect of these supplements includes insomnia, which is one of the primary triggers for anxiety and panic. Similarly, green tea is known to reduce weight but has high amounts of caffeine. Guarana, which a prominent ingredient in weight loss supplements, has twice as much caffeine as a regular cup of coffee. You must also be aware of products that contain ephedra, as it can lead to anxiety and an increased heart rate.

Thyroid gland problems
The thyroid gland, which is a butterfly-shaped gland located in the front portion of the neck, produces thyroid hormones. The main function of these hormones is to regulate the metabolism and energy levels. A dysfunction can lead to abnormalities in the metabolism and result in unusual weight gain or loss. If the thyroid gland produces an excess of thyroid hormones, then it can also cause anxiety symptoms like nervousness, irritability, sleeplessness, and heart palpitations. If you are encountering anxiety symptoms along with a swelling in your neck, fatigue, heat intolerance, or weakness, you must consult your doctor.
