Anxiety is a common mental health issue that affects millions of people around the world. It can manifest in different ways, including physical symptoms, emotional distress, and a decrease in appetite.

While some people may experience an increase in appetite as a result of anxiety, others may find that their appetite is suppressed. In this article, we will explore the reasons why anxiety can suppress our appetite.

What is Anxiety?

Anxiety is a feeling of unease, such as worry or fear, that can be mild or severe. It is a natural response to stress or danger and can help us to stay alert and focused.

However, when anxiety becomes overwhelming and interferes with our daily life, it can be a sign of an anxiety disorder.

How Does Anxiety Affect Our Appetite?

When we experience anxiety, our body produces stress hormones such as cortisol, adrenaline, and norepinephrine. These hormones can affect our appetite in different ways:.

1. Cortisol

Cortisol is known as the stress hormone and is produced by the adrenal glands in response to stress. It can increase blood sugar levels and suppress appetite.

This is because cortisol prepares the body for a fight or flight response by redirecting energy from non-essential functions such as digestion to essential functions such as breathing and circulation. In this way, cortisol can cause a decrease in appetite and a feeling of fullness even if we haven’t eaten enough.

2. Adrenaline

Adrenaline is another stress hormone that is produced by the adrenal glands. It is responsible for the physical symptoms of anxiety, such as a racing heart, sweating, and trembling.

Adrenaline can also suppress appetite by diverting blood flow away from the digestive system and towards the muscles and brain. This can cause digestive discomfort and a decrease in hunger.

3. Norepinephrine

Norepinephrine is a hormone and neurotransmitter that is released by the sympathetic nervous system in response to stress. It can increase heart rate, blood pressure, and respiration.

Norepinephrine can also suppress appetite by decreasing blood flow to the digestive system and increasing blood flow to the muscles and brain. This can cause a decrease in hunger and an increase in feelings of fullness.

4. Mental Health Effects

Aside from the physical effects, anxiety can also have a significant impact on our mental health. Anxiety can cause feelings of worry, fear, and hopelessness, which can lead to a decrease in appetite.

In severe cases, anxiety can lead to depression, which can cause a loss of appetite as well as other symptoms such as fatigue, insomnia, and feelings of worthlessness.

5. Medications

Some medications used to treat anxiety can also cause a decrease in appetite. For example, selective serotonin reuptake inhibitors (SSRIs) can cause nausea, which can lead to a loss of appetite.

Benzodiazepines can also cause a decrease in appetite as a side effect.

Conclusion

Anxiety can have a significant impact on our appetite, causing a decrease in hunger and a feeling of fullness even if we haven’t eaten enough.

This is due to the effect of stress hormones such as cortisol, adrenaline, and norepinephrine, which can redirect energy away from digestion and towards essential functions such as breathing and circulation. Mental health effects and medications can also contribute to a decreased appetite. If you are struggling with anxiety and a loss of appetite, it is important to seek help from a qualified healthcare professional.
