Stomach issues — Causes, quick fixes, and when to see a doctor

Stomach pain, bloating, nausea or diarrhea can wreck your day. Most mild stomach upsets clear in 48–72 hours, but some signs mean you need help fast. This page gives clear, practical steps you can try at home, simple over‑the‑counter options, and the exact warning signs that should send you to a clinician.

What usually causes stomach trouble

Common causes are food poisoning or a viral gastroenteritis, mild food intolerance (like lactose), stress or anxiety, side effects from medicines, acid reflux, and overeating. Chronic causes include IBS or inflammatory bowel disease — those usually come with repeated patterns, weight loss, or blood in stools. If a new medicine started right before your symptoms, that’s a big clue.

Quick fixes you can try at home

Start simple and sensible. First, hydrate — sip water, oral rehydration solution, or clear broth. If you’re vomiting, take small sips often. Stick to bland foods while symptoms ease: the BRAT approach (bananas, rice, applesauce, toast) can help for a day or two.

Avoid dairy, alcohol, caffeine, greasy or spicy meals and heavy fiber until you’re improving. For nausea, ginger tea or candied ginger often helps. Peppermint oil capsules can reduce bloating and cramping for some people, but avoid them if you have heartburn.

OTC meds: antacids or H2 blockers can ease heartburn; bismuth subsalicylate (Pepto) soothes upset stomach and mild diarrhea; loperamide (Imodium) controls non‑bloody, non‑fever diarrhea for short periods. Don’t take loperamide if you have a high fever or bloody stool — that’s a sign to see a doctor.

Probiotics may shorten diarrhea a bit and help recovery after antibiotics, but effects vary. Fiber helps overall gut health and can aid recovery from gastroenteritis when you’re ready — see our piece “Effective Fiber Use for Gastroenteritis Recovery and Prevention” for practical tips.

Rest, gentle walking, and small frequent meals work better than heavy meals when your stomach is upset.

When to seek medical care

Call a doctor or go to urgent care if you have: severe abdominal pain, fever over 102°F (39°C), repeated vomiting lasting more than 24 hours, bloody or black stools, signs of dehydration (dizziness, very low urine output), or unexplained weight loss. Also contact a provider if problems last more than two weeks or keep returning.

If you’re on blood thinners, immunosuppressants, or have a weakened immune system, get medical advice sooner — infections can be more dangerous for you. Bring a list of medicines and a short symptom timeline to your visit; that helps the clinician figure out the cause fast.
