Constipation and anxiety are two common health problems of modern life. Constipation is defined as a decrease in bowel movements and difficulty in defecation, while anxiety is characterised by a constant feeling of worry, fear and tension. These two conditions can seriously affect the quality of daily life of individuals. Constipation causes physical symptoms such as abdominal pain, bloating and general discomfort, while anxiety causes psychological effects such as sleep disturbances, concentration difficulties and difficulties in social relationships. The relationship between constipation and anxiety exhibits a complex interaction on both physiological and psychological levels, and these conditions can often trigger each other. Anxiety can slow down bowel movements, while constipation can exacerbate anxiety by increasing a person's level of stress and anxiety. 

Effects of anxiety on the digestive system

Anxiety triggers the body's ‘fight or flight’ response, leading to various physiological changes. These changes include increased heart rate, tense muscles and slowing of the digestive system. The digestive system is particularly sensitive to the effects of anxiety. Here are the main effects of anxiety on the digestive system:

Slowing of bowel movements: Anxiety can cause bowel movements to slow down. This causes food to stay in the digestive tract longer and leads to constipation.

Stress hormone cortisol: During anxiety, the body releases the hormone cortisol. Cortisol increases the pressure on the digestive system and negatively affects bowel movements.

Gut microbiome: Anxiety can also affect the gut microbiome. A healthy microbiome is critical for digestive health. Anxiety causes disruption of microbial balance and constipation.

The psychological link between anxiety and constipation

The link between anxiety and constipation is not only physiological, but also psychological. Anxiety creates a constant state of worry and fear that negatively affects the quality of life. This is also reflected in the individual's bowel health. 

Stress and anxiety cycle: Anxiety can lead to physical symptoms such as constipation. These physical symptoms can increase a person's stress level, which in turn can worsen the anxiety. Thus, a vicious circle is formed.

Eating habits: Anxiety can affect an individual's eating habits. People with anxiety may consume unhealthy foods or change the frequency of eating. These changes can negatively affect the digestive system and lead to constipation.

Muscle tension: Anxiety can cause muscles to be constantly tense. This tension can also affect the intestinal muscles and slow down bowel movements.

Research on the relationship between anxiety and constipation

Various studies have demonstrated the link between anxiety and constipation. 

The gut-brain axis The gut-brain axis is a system in which the gut and brain communicate with each other. Anxiety can affect this axis, leading to negative effects on the digestive system. A 2020 study proved that anxiety slows down bowel movements and causes constipation.

Psychological interventions: Another study in 2019 showed that psychological interventions (e.g. cognitive behavioural therapy) can be effective in treating constipation. This suggests that constipation can also be alleviated through the management of anxiety.

Nutrition and microbiome: A 2021 study examined how anxiety affects the gut microbiome and how this effect can lead to constipation. This study showed that a healthy diet and probiotics can alleviate symptoms of anxiety and constipation.

Treatment and Management Strategies

Understanding the link between anxiety and constipation allows us to develop more effective strategies in the treatment of these conditions. There are some practices that can be done against the combination of anxiety and constipation.

  1. Stress management: Managing anxiety will alleviate constipation symptoms. Stress management techniques such as meditation, yoga and deep breathing exercises help to reduce anxiety.
  2. Dietary adjustments: A fibre-rich diet increases bowel movements and prevents constipation. In addition, probiotics support digestive health by balancing the gut microbiome.
  3. Physical activity: Regular exercise can promote bowel movements and help prevent constipation. Exercise is also helpful in reducing anxiety.
  4. Psychotherapy: Psychotherapy methods such as cognitive behavioural therapy can be effective in treating anxiety. This treatment also helps to alleviate the physical symptoms caused by anxiety.
