DEHYDRATION WARNING SIGNS

When Should You Go to the ER for Vomiting or Dehydration?

Go to the ER if vomiting keeps you from holding down any fluids for several hours, or if it comes with dizziness, fainting, confusion, very little urine, blood in the vomit, or severe abdominal pain. Infants, older adults, pregnant women, and people with chronic illness can become dehydrated faster and should be seen sooner.
Most stomach bugs pass within a day or two. The danger is losing more fluid than you can replace, which can strain the kidneys and heart and throw off sodium and potassium levels.

YOUR ER VISIT

What Happens When You Visit the ER for Dehydration?

Your physician checks your vital signs, looks for signs of dehydration, and asks how long you’ve been sick and what you’ve been able to drink.

Lab Testing

Blood tests can measure sodium, potassium, kidney function, and blood sugar. Urinalysis helps gauge hydration and check for infection.

IV Fluids When Needed

Patients who can’t drink enough may receive IV fluids. Many people with milder dehydration do well with oral fluids once nausea is controlled.

Nausea Control

Anti-nausea medication may be given so you can start keeping fluids down. Imaging is used only if another cause is suspected.
Treatment depends on your evaluation. Not every patient needs IV therapy, lab work, or imaging.

What Can Cause Vomiting and Dehydration?

Possible causes can include:

Viral & Food-Related Illness

Viral gastroenteritis (“stomach flu”) and food poisoning are the most common causes of vomiting with diarrhea.

Heat & Exertion

Heavy sweating in hot weather, intense exercise, or outdoor work without enough fluid replacement.

Abdominal Conditions

Appendicitis, gallbladder disease, pancreatitis, bowel obstruction, or kidney stones can cause vomiting with pain.

Other Medical Causes

Kidney infection, pregnancy-related nausea, uncontrolled diabetes, migraine, and medication side effects.

QUICK ANSWERS

Vomiting & Dehydration Questions, Answered

When should I go to the ER for vomiting?

Go to the ER if you can’t keep down even small sips of fluid for several hours, or if vomiting comes with dizziness, fainting, confusion, very little urine, blood in the vomit, severe abdominal pain, or a severe headache. Vomiting after a head injury, during pregnancy, or in a young infant also deserves prompt evaluation.

What if I cannot keep water or fluids down?

Try small sips—a teaspoon or two every few minutes—of water or an oral rehydration solution. If you still can’t keep anything down after several hours, or you feel dizzy, weak, or are barely urinating, get evaluated. An emergency physician can treat the nausea and, when needed, give IV fluids.

Get evaluated promptly, especially if you also have a fever, a swollen belly, or green or bloody vomit.

Can an ER treat severe dehydration?

Yes. An emergency room can assess how dehydrated you are, check electrolytes and kidney function, control nausea with medication, and give IV fluids when appropriate. Many patients feel noticeably better within a few hours, though treatment depends on the cause and your overall health.

Vomiting & Dehydration ER — Frequently Asked Questions

Water and oral rehydration solutions are best. Sports drinks can help in mild cases but contain more sugar and less sodium than rehydration solutions. Avoid alcohol and large amounts of caffeine, and sip slowly if you are nauseated.

Mild dehydration often improves within hours of drinking enough fluids. More severe dehydration may take a day or more to correct, depending on the cause and whether vomiting or diarrhea continues.

Not always. Many people recover with oral fluids once nausea is controlled. Your physician may recommend IV fluids if you can’t keep fluids down, have signs of significant dehydration, or have abnormal lab results.

If you feel dizzy, weak, or lightheaded, have someone else drive you. If you have fainted, are confused, or have signs of heat stroke, call 911.

Seek emergency care if a child can’t keep fluids down, hasn’t urinated in 6 to 8 hours, is unusually sleepy or limp, has green or bloody vomit, or vomits after a head injury. A baby under 3 months with repeated vomiting should be seen promptly.
