why do i keep getting diarrhea

Frequent or ongoing diarrhea can come from a lot of different causes, ranging from simple infections or foods that irritate your gut to more serious conditions like inflammatory bowel disease or celiac disease. Because it can lead to dehydration and sometimes signal something significant, persistent diarrhea should always be discussed with a doctor, especially if it’s been going on for more than a few days or keeps coming back.

Common short‑term causes

These are reasons you might have diarrhea for a few days at a time:

• Infections : “Stomach flu” (viral gastroenteritis), food poisoning from bacteria like E. coli, or parasites from contaminated food or water can all cause sudden, watery stools, cramping, nausea, and sometimes fever.

• Medications: Antibiotics, some antacids with magnesium, certain cancer drugs, and other medicines can upset the gut and trigger diarrhea while you are taking them.

• Foodborne triggers: Eating undercooked meat, food that has sat out too long, or unpasteurized dairy/juices can cause acute diarrhea episodes.

Causes of recurring diarrhea

If you “keep getting” diarrhea—episodes that repeat or last weeks—doctors think about:

• Food intolerances: Lactose intolerance (dairy), fructose intolerance, and sensitivity to sugar alcohols in sugar‑free gum/candy often cause repeated loose stools, gas, and bloating after certain foods.

• Irritable bowel syndrome (IBS): IBS with diarrhea involves frequent loose stools along with cramping that often improves after a bowel movement and tends to flare with stress or specific foods.

• Inflammatory bowel disease (IBD): Crohn’s disease and ulcerative colitis can cause ongoing diarrhea, abdominal pain, blood or mucus in the stool, weight loss, and fatigue.

• Celiac disease and malabsorption: Damage to the small intestine from celiac disease or other conditions can make you poorly absorb nutrients and fats, leading to chronic diarrhea, weight loss, and sometimes pale, greasy stools.

• Hormonal or systemic issues: Overactive thyroid, diabetes‑related nerve problems in the gut, and other endocrine conditions can present with long‑term diarrhea.

When it’s an emergency

See urgent or emergency care right away if you have diarrhea plus:

• Signs of dehydration (thirst, dry mouth, little or no urine, dizziness, confusion).

• High fever, severe abdominal pain, or repeated vomiting.

• Blood or black, tar‑like stools, or pus/mucus in the stool.

• Diarrhea lasting more than 2–3 days in adults or any persistent diarrhea in very young children or frail adults.

What you can do now

While waiting to see a clinician:

• Focus on fluids: Take small, frequent sips of water or oral rehydration solutions; avoid a lot of caffeine and alcohol, which can worsen diarrhea.

• Gentle foods: Many people tolerate plain rice, toast, bananas, and boiled potatoes better until things settle; limit very fatty, spicy, or highly processed foods.

• Track patterns: Note when diarrhea happens, what you ate, medications, and other symptoms (like weight loss or blood) to share with a doctor.

Because ongoing diarrhea has many possible explanations and some are serious, the safest next step is to contact a healthcare professional or urgent care, describe how long this has been happening, and ask how soon you should be seen.
