Your stomach can hurt for many different reasons, and some are minor while others are emergencies.

Quick Scoop: What might be going on?

Here are some common, often mild causes of stomach hurting (abdominal pain).

  • Indigestion or “overeating” discomfort, especially after a big, fatty, or spicy meal, can cause burning or fullness high in the belly.
  • Gas and bloating can cause crampy, shifting pain and lots of burping or farting.
  • Constipation often causes dull or crampy lower-belly pain and feeling like you cannot fully poop.
  • Diarrhea, stomach bugs, or food poisoning can cause cramping, nausea, vomiting, and urgent, watery stools.
  • Acid reflux or GERD can cause burning in the upper stomach or chest, sour taste, or pain after lying down.
  • Food allergies or intolerances (like lactose intolerance) can cause cramps, bloating, and diarrhea after certain foods.

There are also more serious causes.

  • Appendicitis: sudden pain that often starts near the belly button and moves to the lower right side, usually gets worse over hours, may come with fever or vomiting.
  • Gallstones: severe pain in the upper right or middle upper belly, may spread to the back or shoulder, sometimes after a fatty meal.
  • Pancreatitis: bad upper-belly pain that can go through to your back, often with nausea and vomiting.
  • Kidney stones or infection: strong side or back pain that may move toward the groin, pain when peeing, or blood in urine.
  • Chronic gut conditions like IBS or Crohn’s disease: ongoing cramps, bloating, diarrhea or constipation for weeks or months.
  • For people with periods: menstrual cramps, endometriosis, or ectopic pregnancy can cause significant lower-belly pain.

Because there are many possibilities, where the pain is, how it feels (sharp, dull, burning, crampy), what makes it better or worse, and what other symptoms you have all matter a lot.

Quick self-check (not a diagnosis)

If you want to think it through while you wait for proper medical advice, ask yourself:

  1. When did it start? Suddenly today, or has it been on and off for weeks?
  1. Where exactly does it hurt (upper, lower, left, right, middle)?
  1. What else is happening?
    • Fever, vomiting, blood in stool or vomit, yellow skin/eyes, chest pain, trouble breathing, or you feel very unwell are red flags.
 * Diarrhea, constipation, bloating, or heartburn point more toward digestion issues.

When to seek urgent help

You should get urgent in‑person medical care or call emergency services if:

  • The pain is sudden, severe, or worsening quickly.
  • You have chest pain, trouble breathing, or pain spreading to your jaw, arm, or back.
  • You have a rigid, very tender belly, or you cannot pass gas or stool at all.
  • You have fever with severe pain, repeated vomiting, or you are unable to keep fluids down.
  • You see blood in your stool or vomit, or your skin/eyes look yellow.
  • You are pregnant (or could be) and have new belly pain.

Simple at‑home steps (only if symptoms seem mild)

If your pain feels mild and you have no red-flag symptoms, some people get relief from:

  • Resting and avoiding heavy exertion.
  • Sipping water or oral rehydration solutions; avoiding alcohol and caffeine.
  • Eating bland foods (like toast, rice, bananas) and avoiding very fatty or spicy foods for a bit.
  • Using a warm (not hot) heat pack on the abdomen.
  • For constipation: more fluids, fiber, and gentle movement if you’re able.

But home measures are not a substitute for a proper medical evaluation, especially if the pain is new, severe, or different from your usual.

Because I don’t know your exact symptoms, history, or risk factors, I cannot tell you the exact reason your stomach is hurting, and this isn’t a diagnosis or a substitute for seeing a clinician. If your pain is strong, has lasted more than a few hours, keeps coming back, or you feel worried, it is safest to contact a doctor or urgent care today.
