Experiencing diarrhea intermittently can be both frustrating and concerning. This condition, often described as having loose or watery stools that come and go, can disrupt daily life and indicate an underlying health issue. If you find yourself frequently asking, “Why do I keep getting diarrhea on and off?” it might be time to consult top gastroenterologists in Bangalore. These specialists are equipped to diagnose and treat the various gastrointestinal conditions that may cause recurrent diarrhea, helping you find relief and improve your quality of life.
Understanding Intermittent Diarrhea
Intermittent diarrhea refers to episodes of loose or watery stools that occur sporadically. This pattern can result from a wide range of factors, including diet, stress, infections, and chronic gastrointestinal disorders. Unlike acute diarrhea, which is typically short-lived and linked to infections or food poisoning, intermittent diarrhea can persist over weeks or even months, often with symptom-free intervals in between.
Common Causes of Recurrent Diarrhea
-
Irritable Bowel Syndrome (IBS):
- IBS is one of the most common causes of chronic, recurrent diarrhea. It’s a functional gastrointestinal disorder characterized by a group of symptoms that affect the large intestine, including abdominal pain, bloating, and changes in bowel habits.
- IBS can cause both diarrhea-predominant (IBS-D) and mixed-type IBS, where individuals experience alternating episodes of diarrhea and constipation. The exact cause of IBS is unknown, but it is often linked to factors like stress, hormonal changes, and certain foods.
-
Food Intolerances and Sensitivities:
- Certain foods can trigger diarrhea in people with food intolerances or sensitivities. Common culprits include lactose (found in dairy products), gluten (found in wheat, barley, and rye), and artificial sweeteners like sorbitol and mannitol.
- For those with lactose intolerance or celiac disease (gluten sensitivity), consuming these substances can lead to recurring episodes of diarrhea.
-
Inflammatory Bowel Disease (IBD):
- IBD encompasses chronic inflammatory conditions like Crohn’s disease and ulcerative colitis, which cause inflammation of the digestive tract. Unlike IBS, which affects bowel function, IBD leads to structural damage in the intestines.
- Symptoms of IBD include persistent diarrhea, abdominal pain, fatigue, and weight loss. Diarrhea in IBD patients may come and go depending on the level of inflammation and disease activity.
-
Infections:
- Recurrent gastrointestinal infections, such as those caused by parasites (e.g., Giardia lamblia) or bacteria (e.g., Clostridium difficile), can lead to bouts of diarrhea that appear to come and go.
- Chronic infections may arise from contaminated food or water and can persist if not properly treated. In some cases, post-infectious IBS can develop after an initial gastrointestinal infection, resulting in recurrent diarrhea.
-
Medications:
- Certain medications, such as antibiotics, laxatives, and nonsteroidal anti-inflammatory drugs (NSAIDs), can cause diarrhea as a side effect. Antibiotics, in particular, can disrupt the natural balance of gut bacteria, leading to antibiotic-associated diarrhea.
- If you are on medication and experiencing intermittent diarrhea, it is important to discuss this with your doctor to explore alternative treatments or adjustments.
-
Stress and Anxiety:
- Stress and anxiety have a well-documented impact on the gut-brain axis, which can influence bowel habits. Stress can trigger or worsen conditions like IBS, leading to episodes of diarrhea.
- Emotional factors can stimulate the gut, causing increased bowel motility and leading to diarrhea, especially in individuals with sensitive digestive systems.
-
Hormonal Changes:
- Hormonal fluctuations, such as those experienced during menstruation, pregnancy, or menopause, can affect bowel habits. Some women report experiencing diarrhea around their menstrual cycle due to hormonal changes.
- Conditions like hyperthyroidism (an overactive thyroid) can also cause frequent, loose stools.
-
Small Intestinal Bacterial Overgrowth (SIBO):
- SIBO occurs when there is an abnormal increase in the number of bacteria in the small intestine. This can interfere with the digestion and absorption of nutrients, leading to symptoms like bloating, abdominal pain, and diarrhea.
- SIBO can be caused by a variety of factors, including previous gastrointestinal surgery, motility disorders, or conditions that slow the movement of food and waste products through the digestive system.
Diagnosing the Cause of Intermittent Diarrhea
Given the wide range of potential causes, it’s crucial to seek a proper diagnosis if you experience recurrent diarrhea. A gastroenterologist in Bangalore can help identify the root cause of your symptoms through a comprehensive evaluation, which may include:
-
Medical History and Physical Examination: The doctor will take a detailed history of your symptoms, dietary habits, medication use, and any associated factors like stress or recent travel. A physical examination can also help identify signs of dehydration, abdominal tenderness, or other abnormalities.
-
Stool Tests: Stool analysis can detect the presence of infections, parasites, blood, or markers of inflammation. This test can help identify infections like Giardia or C. difficile, as well as rule out other conditions.
-
Blood Tests: Blood tests can help assess for signs of infection, inflammation, or other underlying conditions such as celiac disease or thyroid dysfunction.
-
Endoscopy or Colonoscopy: For persistent or unexplained diarrhea, a gastroenterologist may recommend an endoscopy or colonoscopy. These procedures allow direct visualization of the digestive tract and can help diagnose conditions like IBD, celiac disease, or other structural abnormalities.
-
Lactose Intolerance or Celiac Disease Tests: Specific tests can determine whether food intolerances, such as lactose intolerance or celiac disease, are contributing to your symptoms.
Managing and Preventing Recurrent Diarrhea
Once the underlying cause of intermittent diarrhea is identified, a tailored treatment plan can be developed. Management strategies may include:
-
Dietary Modifications:
- Identifying and avoiding trigger foods is crucial for managing conditions like IBS or food intolerances. A low-FODMAP diet, which restricts certain fermentable carbohydrates, may benefit those with IBS.
- For individuals with lactose intolerance or celiac disease, eliminating lactose or gluten from the diet can significantly reduce symptoms.
-
Medications:
- Depending on the diagnosis, medications such as antispasmodics, anti-diarrheal agents, or antibiotics may be prescribed. For example, antispasmodics can help manage IBS symptoms, while antibiotics like rifaximin are used to treat SIBO.
- In cases of IBD, treatment may involve anti-inflammatory drugs, immunosuppressants, or biologic therapies to control inflammation and reduce diarrhea.
-
Probiotics:
- Probiotics can help restore the natural balance of gut bacteria, especially after antibiotic use. They may also alleviate symptoms of IBS and other digestive disorders.
-
Stress Management:
- Techniques such as mindfulness, relaxation exercises, and cognitive-behavioral therapy can help manage stress and reduce its impact on gastrointestinal symptoms.
- Managing stress is particularly important for individuals with IBS, as stress can exacerbate symptoms.
-
Lifestyle Adjustments:
- Regular exercise, adequate hydration, and getting enough sleep are important for overall digestive health. Maintaining a healthy lifestyle can help manage and prevent episodes of diarrhea.
When to See a Gastroenterologist
While occasional diarrhea is common, recurrent or chronic diarrhea warrants medical evaluation. Seek the advice of top gastroenterologist in Bangalore if you experience:
- Diarrhea that persists for more than a few weeks.
- Unexplained weight loss, blood in the stool, or severe abdominal pain.
- Signs of dehydration, such as excessive thirst, dry mouth, or decreased urine output.
- Symptoms that interfere with daily activities and quality of life.

Understanding why you keep getting diarrhea on and off requires a thorough evaluation by a healthcare professional. Consulting best gastroenterologist in Bangalore can help you get to the root of the problem and develop an effective management plan.
