When to Go to an Emergency Room in Katy, TX?

Illnesses and injuries can strike unexpectedly, leaving us uncertain about where to seek care, especially when our
regular doctor's office is closed. While urgent care clinics in Katy, TX and the nearby West Houston area can fill a gap
for things like a cough or non-life-threatening illnesses such as colds, flu, or minor infections, they are often not equipped to handle more serious emergencies. Emergency rooms in Katy, TX like ER Katy are trained and prepared to handle severe situations that might require rapid or advanced treatments. Common reasons to go to an ER in Katy, TX, rather than an urgent care clinic, can include:

Severe chest pain or difficulty breathing

Signs of a stroke, such as sudden weakness or speech difficulty

Severe injuries, fractures, or severe bleeding

Seizures or loss of consciousness

Severe allergic reactions

Severe burns

Severe abdominal pain

Suicidal or homicidal thoughts

Severe head injuries

If you are experiencing an emergency, or are unsure where to go, don’t wait. ER Katy is open 24/7 and is ready to help you and your family, no matter the situation.
