Anxiety can induce a decrease or increase in appetite. These effects are mostly caused by hormonal changes in the body, although some people may delay eating as a consequence of anxiety-related bodily symptoms. Individuals who suffer from persistent or severe anxiety should consult a doctor. There are several treatments available for anxiety disorders, including medication, cognitive behavioral therapy (CBT), and self-help techniques. When you're suffering from anxiety, it's difficult to sit down at the table and enjoy your meal. You might feel nauseous or anxious about eating in a new place or with new people. Anxiety can also cause you to eat too much or too little. If this problem is ongoing, then you should talk to your doctor about treating your condition. Sleep problems are very common among people who struggle with anxiety. About 80% of individuals who suffer from anxiety disorders experience insomnia at some point in their lives. This is because anxiety can be a factor in poor sleep patterns, such as having difficulty falling asleep or experiencing early morning awakenings. People who suffer from anxiety often have physical symptoms when they feel threatened or insecure. These symptoms include rapid heart rate, sweating, tremors, and nausea. For some people, these feelings are strong enough to cause them to avoid situations that could potentially trigger another attack.
