Why Do I Have Diarrhea Every Morning?

Medically reviewed by Dr. Ola Tarabzuni


Experiencing daily morning, diarrhea can be attributed to various factors. It could be triggered by dietary choices, such as consuming problematic foods, excessive caffeine, and artificial sweeteners. Medical conditions like IBS, IBD, or food intolerances may also contribute. Stress and anxiety can impact bowel movements as well.

This blog discusses the causes, symptoms, and management in detail. 

What Is Morning Diarrhea?

Morning diarrhea refers to loose or watery bowel movements, specifically in the morning, typically soon after waking up. It is characterized by the passage of frequent and urgent stools that are more liquid in consistency compared to regular bowel movements. Waking up with diarrhea can be frustrating and vary in severity, frequency, and duration depending on the underlying cause.

Why Causes Diarrhea Every Morning?

Experiencing diarrhea every morning can be concerning, and several potential reasons exist for this symptom. It’s important to note that a doctor should be consulted for an accurate diagnosis and appropriate treatment. Here are some possible causes for having diarrhea every morning:

Irritable Bowel Syndrome (IBS)

A typical chronic condition that affects the digestive system is IBS. It might result from constipation, persistent diarrhea, or a combination. Due to normal variations in bowel motility, some people with IBS have more frequent bowel movements in the morning.

Inflammatory Bowel Disease (IBD)

IBD encompasses diseases that cause persistent inflammation and ulceration in the digestive tract, including Crohn’s disease and ulcerative colitis. IBD frequently causes diarrhea, which might happen in the morning due to increased intestinal movement after waking up.

Food Intolerances or Sensitivities

Certain individuals may have difficulty digesting specific types of food, such as lactose or gluten. These intolerances can lead to digestive symptoms, including diarrhea, which may occur consistently in the morning if those foods are regularly consumed.

Caffeine and Morning Diarrhea

Experiencing diarrhea every morning after consuming coffee is a relatively common occurrence for some individuals. It is a stimulant to the digestive system and causes increased bowel movements. The caffeine content in coffee can have a laxative effect, leading to loose stools or diarrhea.

Additionally, coffee stimulates gastric acid production, which can further irritate the digestive system and contribute to diarrhea. Some individuals may also have a sensitivity or intolerance to components in coffee, such as certain oils or acids, which can trigger gastrointestinal distress and diarrhea.

If you consistently experience diarrhea after drinking coffee, reduce or eliminate your coffee intake to see if the symptoms improve. You could also switch to decaffeinated coffee or explore alternative beverages that are less likely to cause digestive issues.

Medications or Supplements

Antibiotics and specific dietary supplements, for example, can interfere with the digestive system’s regular operation and cause diarrhea. Medication used in the evening or right before bedtime may result in morning diarrhea.


Diarrhea can be brought on by gastrointestinal infections brought on by bacteria, viruses, or parasites. More frequent bowel motions, including in the morning, may indicate an infection.

Stress and Anxiety

Emotional stress and anxiety can impact the digestive system, leading to changes in bowel movements. Some individuals may experience increased bowel activity, including diarrhea, during heightened tension, which may be more prominent in the morning.

Diarrhea in the Morning in Females

Suppose you are a female experiencing diarrhea every morning. In that case, it is essential to consider potential causes for this recurring issue other than the usual, Including IBS, trigger foods, or food allergies. Several factors specific to females could contribute to morning diarrhea.

Hormonal changes during the menstrual cycle can affect bowel movements, resulting in looser stools. Additionally, pregnancy can lead to gastrointestinal changes and increased sensitivity, potentially causing diarrhea.

Treatments For Morning Diarrhea

Treatment for morning diarrhea must address the underlying cause. A combination of dietary modifications and medications may be used as treatment.

Dietary Changes

Keeping a food journal can help identify foods that cause IBS. Accordingly, Depending on the triggers, you might want to avoid things like:

  • Highly gas-producing foods and beverages, including carbonated drinks, raw fruit, and some vegetables, such as broccoli and cauliflower
  • Bread, cereals, pasta, and other foods containing gluten
  • Foods made with FODMAPs, which are any of several types of carbohydrates, including fructose and lactose


Biologic medications block the chemicals that cause intestinal inflammation. This more recent type of therapy has dramatically changed the treatment for IBS, according to a 2020 review trusted Source.

While some medications can be taken by self-injection, others must be given intravenously (IV) under a healthcare professional’s supervision. Adalimumab (Humira), infliximab (Remicade), and golimumab (Simponi) are a few of them.

Other medications sometimes prescribed for IBS include antidepressants. If diarrhea is the problem, but there’s no diagnosed depression, antidepressants, including imipramine (Tofranil) or desipramine (Norpramin), may help. Anticholinergic medications, such as dicyclomine (Bentyl), can help reduce bowel spasms that may cause diarrhea. Of course, antidiarrheal medications such as loperamide (Imodium) may be helpful.

Treating IBD means reducing the inflammation that’s causing your symptoms.

Some of the first anti-inflammatory drugs you may be prescribed include corticosteroids. Other IBD medications include aminosalicylates such as mesalamine (Asacol HD), balsalazide (Colazal), and olsalazine (Dipentum).

A doctor may also prescribe immunosuppressant drugs such as cyclosporine (Gengraf), mercaptopurine (Purixan), and methotrexate (Trexall) to help prevent the release of inflammatory chemicals in the wall of the intestine.

Antiviral or antibiotic medications can treat infections, but some medicines may cause diarrhea. 

Stress may be causing your morning diarrhea or is responsible for IBS flare-ups

How To Prevent Morning Diarrhea?

Finding and treating the root cause is necessary for preventing morning diarrhea. Here are some broad preventative measures for morning diarrhea:

Maintain a Healthy Diet

Pay close attention to your diet and look for foods that might cause diarrhea. Steer clear of oily or spicy foods, which are known to aggravate the digestive tract. Reduce your intake of alcohol and caffeine as well because they can cause bowel movements to become more active.

Stay Hydrated

To stay hydrated, sip on water frequently throughout the day. It’s crucial to replenish lost fluids after diarrhea to avoid becoming dehydrated. However, limit your coffee and sugary drinks intake as they can worsen diarrhea.

Manage Stress

Diarrhea and other gastrointestinal problems can be made worse by stress and worry. Hence, take part in stress-relieving activities, including relaxation hobbies, exercise, meditation, and deep breathing. To manage stress and anxiety, if necessary, seek out expert assistance.

Identify Food Intolerances

Keep a food diary to track symptoms and discover any food intolerances or sensitivities if you feel certain foods are causing your morning diarrhea. Problematic food identification may be facilitated by elimination diets or working with a trained dietitian.

Practice Good Hygiene

Preventing illnesses that can cause diarrhea depends heavily on good hand hygiene. Thoroughly wash your hands with soap and water before handling food, using the lavatory, and touching potentially contaminated surfaces.

Review Medications

Consult your doctor if your medicine is the root of your morning diarrhea. They can change your medicine, boost the dosage, or offer advice on handling the side effects.

Why Do I Have Diarrhea But Not Sick?

It might be perplexing to experience diarrhea without being ill with an infection or exhibiting other conventional disease symptoms. Several things can cause diarrhea without a visible illness or loose stools in the morning with no pain. Here are a few such justifications:

Certain Foods or Beverages

Diarrhea can be brought on by specific meals or drinks, especially if you are sensitive or intolerant to them. Diarrhea can be brought on by various conditions, such as lactose intolerance, gluten intolerance (celiac disease), or sensitivity to hot or oily foods.

Medications or Supplements

The equilibrium of microorganisms in the gut can be upset by some drugs, including antibiotics and some dietary supplements, which can cause diarrhea as a side effect. It might be the culprit if you just started using a new vitamin or prescription.

Food Poisoning

Diarrhea can be a symptom of foodborne infections or food poisoning. However, they may not manifest right away after eating contaminated food. Because symptoms may take many hours or even days, you might not link your diarrhea to a particular meal.

Stress and Anxiety

Emotional stress and anxiety can impact the digestive system and lead to changes in bowel movements. Diarrhea can be a physical manifestation of tension without being accompanied by other signs of illness.

Irritable bowel syndrome (IBS)

IBS is a long-term digestive tract disorder that, among other symptoms, can result in diarrhea. Changes in gut motility, specific meals, or stress are frequently its causes.

Other conditions

Various gastrointestinal disorders, such as functional diarrhea or microscopic colitis, can cause chronic diarrhea without an apparent illness.

IBS, foods, or medications may cause diarrhea. Your doctor can help determine the cause

What Foods Trigger Morning Diarrhea in IBS?

Irritable bowel syndrome (IBS) sufferers may experience a variety of symptom triggers, including particular meals. While individual triggers may differ, the following are some specific dietary categories that have been linked to the development of IBS symptoms:


FODMAPs, a class of carbohydrates that includes fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, can be challenging for some IBS sufferers to digest. Some fruits (including apples and cherries) and dairy products with lactose. Additionally, wheat and other grains, garlic, onions, and artificial sweeteners like sorbitol and mannitol are examples of foods rich in FODMAPs.

Gas-Producing Foods

Some foods can contribute to excessive gas production in the digestive system, leading to bloating and discomfort for individuals with IBS, e.g., beans, lentils, cabbage, broccoli, onions, carbonated beverages, and certain high-fiber foods.

Spicy or Fatty Foods

Spicy foods, greasy or fried foods, and heavily seasoned dishes can potentially trigger IBS symptoms, particularly in sensitive individuals. These foods can stimulate the digestive system or be harder to digest.

Caffeine and Alcohol

Beverages and drinks containing caffeine, like coffee, tea, and energy drinks, can irritate the digestive system and may trigger symptoms. Similarly, alcoholic beverages can contribute to IBS symptoms in some individuals.

Gluten-Containing Foods

While only a few percent of people with IBS have celiac disease (an autoimmune disorder triggered by gluten), some individuals may experience gastrointestinal symptoms when consuming gluten-containing foods like wheat, barley, and rye.

You can consult a doctor to discuss foods you should avoid with morning diarrhea.


Morning diarrhea, the unpleasant surprise that greets you with loose stools right after waking up, can have various causes. It’s not something to brush off as usual. Possible culprits include dietary triggers, stress, underlying conditions like IBS or infections, and certain medications. But fear not! There are ways to prevent it. From watching your diet and staying hydrated to managing stress and identifying food intolerances, you can take control. Speaking of diets, did you know certain foods can trigger IBS symptoms? Foods like FODMAPs, spicy dishes, and even that morning cup of joe could be the culprits.

So, consult a healthcare professional to discover what’s behind your morning discomfort and embark on a journey to better digestive health.
