How Do Stress and Digestion Go Together?

Stress and DigestionWe have all been stressed at one point in our life. It is a feeling we get of emotional or physical tension making us feel frustrated, angry, scared, or nervous. One of the most common ways we feel stressed is during our fight-flight response which is a common response in our body when facing adversity or an ultimatum. In brief spurts, stress can be a positive advantage, such as helping us avoid danger or meeting a deadline. However, chronic stress, which lasts a long time, has been harmful to your health. This article will highlight the link between stress and digestion and how that can affect your health.

Stress is a normal feeling. There are two main types of stress:

  • Acute stress – this is short-term stress that goes away quickly. You feel it when you get into an argument with someone, run late to an appointment, or go sky diving. It helps you manage dangerous situations. It also occurs when doing something new and adventurous. Everyone experiences the effect of acute stress at one time or another.
  • Chronic stress – this is a stress that lasts for a longer period of time. You may have chronic stress if you face financial burdens, are stuck in an unhappy relationship, or face a toxic work environment. Chronic stress is defined as a period of stress that is ongoing for weeks or months at a time. Chronic stress has been linked to many health problems, such as digestive issues.

Signs of Too Much Stress

Stress can cause many types of physical and emotional symptoms. Here are some signs that stress may be affecting you:

  • Diarrhea or constipation
  • Forgetfulness
  • Frequent aches and pains
  • Headaches
  • Lack of focus
  • Sexual problems
  • Stiffness in the jaw
  • Fatigue
  • Trouble sleeping or sleeping too much
  • Upset stomach
  • Weight loss or gain


The causes of stress differ from one person to another. You can have stress from good challenges as well as bad ones. Some common sources of stress include:

  • Getting married 
  • Starting a new job
  • The death of a spouse or close family member
  • Getting fired
  • Retiring
  • Having financial burdens
  • Moving
  • Having a health setback

Stress and the Body

When your body is in a state of stress, hormones are released to react to the feeling. These hormones have various effects on your body, causing your body to tense and increase your heart rate. The main hormones released in your body are:

  • Epinephrine
  • Norepinephrine
  • Cortisol

What is Epinephrine? 

Epinephrine, commonly known as adrenaline, is responsible for our fight or flight response. The adrenal glands produce it after receiving a brain message during high-stress situations. Epinephrine works by increasing blood flow to muscles, pupil dilation response, and blood sugar level.  

What is Norepinephrine? 

Norepinephrine is a home similar to adrenaline and is also released from the adrenal glands. One of the primary roles of norepinephrine is arousal. It allows individuals to become more aware, awake, and focused when stressed. It also acts in shifting blood flow away from certain areas such as skin and towards more essential areas such as muscles.

What is Cortisol? 

Cortisol is considered a steroid hormone and is often referred to as the stress hormone. The adrenal glands produce it. The body initially takes several minutes to release cortisol due to its multi-step process involving two additional minor hormones.

The amygdala, a part of the brain, has to recognize a threat. It then sends a message to the part of the brain known as the hypothalamus, which releases CRH, corticotropin-releasing hormone. CRH then tells the pituitary gland to release ACTH, adrenocorticotropic hormone, which tells the adrenal glands to produce cortisol. 

In survival mode, the optimal amounts of cortisol can be lifesaving. It helps maintain fluid balance and blood pressure while regulating body functions that are not crucial at the moment, like reproductive drive, immunity, digestion, and growth.

However, when you have a problem over a long period of time, the body continuously releases cortisol, and chronically elevated levels lead to health problems. High levels of cortisol in the body are linked to:

  • Weaker immune system
  • High blood pressure 
  • High blood sugar and Diabetes
  • Decrease libido
  • Weight gain and Obesity
  • Digestion problems
  • Heart Disease
  • Depression and Anxiety
  • Acne and Eczema
  • Menstrual Complications

Stress and Digestive Health


A neuron is a nerve cell that receives and sends electrical signals over long distances within the body. It receives electrical input signals from sensory neurons and other neurons. These neurons are what causes the commonly known feelings called “gut feeling” and “butterflies” in the gastrointestinal tract. When the body is stressed, it affects the brain and gut communication triggering pain, bloating, and other gut discomforts to be felt more easily. The gut is also occupied by millions of bacteria, which can influence the gut’s health and the brain’s health, impacting the ability to think and affect emotions.

Stress in the early life of an individual can change the development of the nervous system and how the body reacts to stress. These changes can increase the risk for later gut diseases or create dysfunction within the gut. This means that there is a great importance on stress and digestion. 


During periods of high stress, individuals react differently in food intake. Individuals may eat much more or much less than usual. Many also increase their use of alcohol or tobacco. This results in heartburn or acid reflux. Furthermore, the presence of stress on its own can also increase the severity of regularly occurring heartburn pain. Frequent or constant reflux can lead to gastroesophageal reflux disease, GERD. In rare cases, spasms occur in the esophagus, set off by intense stress, and can be easily mistaken for a heart attack. Stress also may make swallowing foods difficult or increase the amount of air swallowed, which increases burping, gassiness, and bloating. 


Chronic stress can cause aching, bloating, nausea, and other stomach discomfort sensed more easily. Furthermore, in severe cases of chronic stress, vomiting may occur. Additionally, stress may cause an unnecessary increase or decrease in appetite. This can cause individuals to turn to unhealthy diets to reduce their weight gain/loss and, in turn, deteriorate one’s mood.

Contrary to popular belief, stress does not increase acid production in the stomach nor causes stomach ulcers. A bacterial infection actually causes the latter. When stressed, ulcers may be more bothersome. 


Similar to how stress can cause aching, bloating, and nausea in the stomach, it can also have the same effects on the bowel. Thus this can have a detrimental effect on how quickly food moves through the body, causing either diarrhea or constipation. With stress impacting how quickly food is moved through the bowel, it, in turn, affects nutrient absorption. Certain nutrients require a longer period to have proper absorption. Lack of proper absorption has also been linked to increased gas production. Along with affecting the movement of food, it can induce muscle spasms in the bowel area, which can be extremely painful. Lastly, stress can make the intestinal barrier weaker and allow gut bacteria to enter the body. Although the intensities have a constricted barrier to protect from food-related bacteria, the constant short requirement for inflammatory action can lead to chronic mild symptoms.

As you can see, stress can have many detrimental effects on digestive health. Stress and digestive health are significant to people with chronic bowel disorders, such as inflammatory bowel disease or irritable bowel syndrome. This can be attributed to the gut nerves being more sensitive, the constant changes in gut microbiota, how quickly food moves through the gut, and/or changes in gut immune responses. In the next section, I will explain how stress affects individuals with digestive illnesses.

Stress and Inflammatory Bowel Diseases

Inflammatory bowel disease includes diseases such as Crohn’s Disease and Ulcerative Colitis. The study’s conclusion found that chronic stress, depression, and unfavorable life events can increase the risk of relapse in patients. This study recognized various mechanisms by which stress affects both the systemic and gastrointestinal immune and inflammatory responses. The study noted therapeutic interventions focused n stress reduction remains a challenge. Current clinical trials monitoring the effects of stress reduction techniques on IBD have not shown promise (R).

Stress and Gut HealthIrritable Bowel Syndrome

Irritable bowel syndrome, IBS, is a common condition that affects the digestive system. In a study looking at around 600 people with gastroenteritis, a condition in which a person experiences temporary inflammation of the stomach and/or intestines, researchers discovered that patient’s ability to handle stress is a crucial factor in whether they went on to develop IBS. Those with higher levels of stress, anxiety, and negative illness were at greater risk of developing IBS (R).

Gastroesophageal Reflux Disease

Researchers found no increase in acid reflux when patients were under acute stress (R). Conversely, when patients were chronically anxious, they were more likely to notice worsening of their symptoms. In summary, their attitudes affected their perception of the symptom severity. 

Peptic Ulcer Disease

Helicobacter pylori, H. pylori, is a type of bacteria that results in many ulcers found in humans. Although a popular belief is that eating spicy and having a stressful life can cause ulcers and impact our digestive health, that is not the case. H. pylori cause ulcers by weakening the protective mucous coating of the esophagus and stomach. This, in turn, causes acid to be able to get through the sensitive lining beneath. The combination of the acid and the bacteria irritate the lining, causing a sore or ulcer. Recently, some evidence suggests ongoing stress leads to mucosal lining inflammation, thus allowing gastric acid to irritate the sensitive stomach lining underneath (R).

All Digestive Conditions

Stress increases gut motility and fluid secretion. This is why you might get a bout of diarrhea or repeated urges to urinate during or following a stressful event. Stress can both delay emptying stomach contents and speed up material passage through the intestines. This combination of activity leads to abdominal pain and altered bowel habits. Additionally, acute psychological stress decreases a person’s pain threshold.
