FAINTING WARNING SIGNS
When Is Fainting an Emergency?
Fainting is an emergency when it happens during exercise, while lying down, or without warning, or comes with chest pain, palpitations, shortness of breath, a head injury, or confusion that doesn’t clear. It also needs urgent evaluation if you have heart disease, a family history of sudden cardiac death, or repeated episodes.
Fainting, or syncope, happens when blood flow to the brain briefly drops. It is often caused by something benign, like standing too quickly or dehydration, but it can also be the first sign of a dangerous heart rhythm or other serious condition. The cause can’t be known from the faint itself.
Get emergency care after fainting with:
- Chest pain or pressure
- A racing, pounding, or irregular heartbeat
- Shortness of breath
- Fainting during exercise or while lying down
- A head injury or serious fall
- Confusion that lasts or trouble speaking
- Heart disease or a family history of sudden death
- More than one faint in a short time

Signs You May Be About to Faint
Many people feel it coming.
Common warning signs
- Lightheadedness or dizziness
- Tunnel vision or spots in your vision
- Sweating, nausea, or feeling warm
- Ringing in your ears
- Sudden weakness or pale skin
If you feel faint, sit or lie down right away with your legs raised to help blood flow to the brain.
What to Do if Someone Faints
Simple steps can prevent injury.
Lay the person flat on their back and raise their legs about 12 inches if there is no injury. Check that they are breathing, loosen tight clothing, and don’t give food or drink until they are fully awake. Stay with them.
Call 911 if they don’t wake within a minute, aren’t breathing normally, or are hurt. If there is no normal breathing, call 911 and start CPR if you are trained.
Fainting With Chest Pain or Palpitations
A heart rhythm cause needs to be ruled out.
Fainting with a racing, pounding, or irregular heartbeat, chest discomfort, or shortness of breath can signal a heart problem, such as an abnormal rhythm. Get emergency care promptly and call 911 for severe symptoms.
Learn more on our chest pain ER and heart palpitations pages.
Fainting With a Head Injury
A fall can cause injuries beyond the faint itself.
If you hit your head when you fainted, or you take blood thinners, you need evaluation for bleeding in the brain and for a concussion, even if you feel fine afterward. Watch for headache, repeated vomiting, confusion, or drowsiness.
See our head injury and concussion page for warning signs.
HIGHER-RISK PATIENTS
Fainting in Older Adults, Pregnancy, and Young People
The reasons for fainting, and the urgency, can differ by age and situation.
In older adults, fainting is more likely to involve the heart or medication effects, and falls can cause fractures or head injuries. A first faint at an older age deserves evaluation rather than reassurance.
Fainting during pregnancy, or fainting with lower abdominal pain or vaginal bleeding when pregnancy is possible, needs prompt emergency evaluation. In children and teens, fainting during exercise or without a clear trigger should also be checked.
YOUR ER VISIT
What Happens When You Visit the ER After Fainting?
The team starts with your vital signs and blood sugar and asks what happened before, during, and after the faint. A witness account can be very helpful.
History & Vital Signs
Blood pressure, heart rate, oxygen level, and blood sugar are checked, along with your medical history and medications.
EKG
An EKG looks for abnormal heart rhythms and other signs of a heart cause.
Lab Tests & Imaging
Blood tests can find anemia, low sugar, or electrolyte problems, and a head CT can check for injury when needed.
If dehydration is found, IV fluids may be given. Patients who need hospital admission or specialist care are transferred.
What Can Cause Fainting?
A physician may consider:
Reflex (Vasovagal) Faints
Triggered by pain, standing too long, heat, stress, or the sight of blood.
Low Blood Pressure & Dehydration
Standing up quickly, fluid loss, or blood pressure medications.
Heart Problems
Abnormal rhythms, valve disease, or weakened heart muscle.
Other Causes
Low blood sugar, anemia, bleeding, a seizure, or a blood clot in the lungs.
This list is general information, not a diagnosis. A single faint can have many possible causes.
QUICK ANSWERS
Fainting Questions, Answered
When should I go to the ER after fainting?
Go if the faint came with chest pain, a racing or irregular heartbeat, shortness of breath, a head injury, or confusion, or if it happened during exercise or without warning. Also go if you have heart disease, are pregnant, or have fainted more than once. Call 911 if someone doesn’t wake up quickly.
Should I go to the ER if I fainted but feel fine now?
It is wise to be checked, especially if you have heart disease, are older, hit your head, or the faint had no clear trigger. Feeling well afterward doesn’t rule out a rhythm problem. An EKG and basic tests can often be done quickly and may offer answers.
Can dehydration make you faint?
Yes. Dehydration lowers blood volume and blood pressure, which can cause lightheadedness and fainting, especially in Houston’s heat or after vomiting or diarrhea. Dehydration can also hide other problems, so repeated or unexplained fainting should still be evaluated.
Where should I go in Houston after passing out?
Go to an emergency room, or call 911 if the person is hurt or not waking up. The Heights Emergency Room at 101 N Loop W #300, Houston, TX 77018, is open 24/7 with EKG, lab testing, and CT imaging. No appointment is needed.
What should I do if someone faints and doesn’t wake up?
Call 911 immediately. Check whether they are breathing normally, and if they aren’t, start CPR if you are trained and follow the dispatcher’s instructions. Don’t move them if you suspect a neck injury, and don’t give anything by mouth.
EMERGENCY SAFETY
When Should You Call 911 After Fainting?
Call 911 if the person is hard to wake, isn’t breathing normally, or shows signs of a heart emergency or serious injury.
Call 911 for:
- Not waking up within about a minute
- Not breathing normally
- Chest pain or pressure
- A seizure
- A serious fall or head injury
- Fainting while pregnant
- Confusion, weakness, or trouble speaking
- Another faint soon after the first
Paramedics can check the heart rhythm, blood sugar, and blood pressure on scene and on the way.
Never drive yourself after fainting; it can happen again without warning.

FAQ
Fainting ER — Frequently Asked Questions
Fainting is a brief loss of consciousness with quick recovery, sometimes with a few muscle jerks. A seizure usually lasts longer and is followed by confusion or drowsiness. A physician can help tell them apart.
Anxiety can cause fast breathing and lightheadedness, and occasionally a faint. But a first-time or unexplained faint shouldn’t be assumed to be anxiety until other causes are checked.
Most people regain consciousness within a minute. If someone stays unresponsive longer, or is confused or not breathing normally, call 911.
Not until a physician has evaluated you. Fainting can recur without warning, which makes driving unsafe until the cause is known.
Yes. Blood pressure medications, diuretics, and some other drugs can lower blood pressure or affect heart rhythm. Bring a list of your medications to the ER.
No. The Heights Emergency Room is a walk-in emergency room open 24/7. If someone isn’t waking up, call 911.
