Abdominal Emergency Care Houston

When Stomach Pain May Be More Serious

The abdomen contains the stomach, intestines, appendix, liver, gallbladder, pancreas, kidneys, bladder and reproductive organs. Pain may also originate from the chest, back or blood vessels, so identifying the source often requires an examination and diagnostic testing.

NorthStar provides around-the-clock emergency evaluation for adults and children. Walk in at any hour for unusual, persistent or worsening symptoms. Call 911 when symptoms are life-threatening or safe transport is not possible.

Important: Mild pain does not always mean the condition is minor. Treatment and testing are selected after an individual medical assessment.

Abdominal and Stomach Pain Evaluation

Pain location, timing, movement and associated symptoms provide clues, but they cannot confirm the cause without medical evaluation.

Emergency physician examining a patient with abdominal pain
CAUSE

Possible Causes of Abdominal Pain

Many digestive, urinary, reproductive and non-abdominal conditions can feel similar.

Conditions physicians may consider
  • Appendicitis, gallstones or gallbladder inflammation
  • Kidney stones or urinary infection
  • Gastroenteritis, gastritis or peptic ulcer disease
  • Pancreatitis, constipation or bowel obstruction
  • Diverticulitis or inflammatory bowel disease
  • Foodborne illness or liver-related conditions
  • Ovarian, pelvic or pregnancy-related emergencies
  • Internal injury, heart or lung conditions

Only an examination and appropriate testing can identify the likely cause.

MAP

What Pain Location May Suggest

Upper, lower, side, back or generalized pain can guide the initial evaluation.

Location and symptom pattern
  • Upper abdomen: stomach, gallbladder, pancreas, liver, heart or lungs
  • Lower right: appendix, bowel, urinary or reproductive causes
  • Lower left: colon, urinary tract or reproductive organs
  • Side or back: kidney stones, kidney infection or muscle injury
  • General cramping: infection, diarrhea, gas or bowel concerns

Tell the physician whether pain began suddenly, moves, comes in waves, worsens with movement or eating, or occurs with fever, vomiting, urinary symptoms, bleeding or stool changes.

MVC

Abdominal Pain After an Accident

Prompt evaluation after a collision, fall or direct blow to the abdomen.

Trauma warning signs

Seek care for new or worsening pain, swelling, firmness, marked tenderness, seat-belt bruising, dizziness, fainting, clammy skin, shoulder pain, vomiting, blood in urine or stool, chest symptoms or possible pregnancy.

Internal injury can occur without dramatic external marks. Call 911 after major trauma or when symptoms suggest internal bleeding or shock.

PREG

Abdominal Pain During Pregnancy

Assessment of severe, persistent or one-sided pain during pregnancy or postpartum.

Pregnancy warning signs

Prompt evaluation is important when pain occurs with vaginal bleeding, fainting, shoulder pain, fever, severe vomiting, fluid leakage, contractions, reduced fetal movement or breathing difficulty.

Tell the team immediately if you are pregnant, recently gave birth or could be pregnant. Pregnancy testing, ultrasound, laboratory work and other imaging may be considered.

ULCER

Ulcer & Upper Abdominal Symptoms

Emergency evaluation of severe pain, bleeding signs and acute complications.

Emergency versus ongoing care

Ulcers may cause burning or aching upper abdominal pain, nausea, bloating or discomfort related to meals. Severe pain, vomiting blood, black stool, fainting or weakness may indicate bleeding or another complication.

NorthStar can evaluate emergency symptoms and acute complications. Ongoing ulcer diagnosis, endoscopy and long-term treatment may require primary or gastroenterology care.

KIDS

Pediatric Abdominal Pain

Age-appropriate evaluation for infants, children and teenagers.

When children need prompt care

Seek prompt assessment for severe or localized pain, a swollen or rigid abdomen, repeated vomiting, blood in vomit or stool, high fever, unusual sleepiness, dehydration, pain after injury or a child who cannot walk comfortably because of pain.

Children may not describe symptoms clearly, and appendicitis can present differently by age.

Digestive Symptom Care

Nausea, Vomiting and Diarrhea

Stomach viruses are common, but repeated fluid loss, severe pain, bleeding or high-risk medical conditions can make digestive symptoms an emergency.

Nausea and Vomiting Evaluation

The physician considers when symptoms began, vomiting frequency, pain, fever, recent food and travel, medication use, pregnancy possibility and health conditions. Testing may include blood work, urinalysis, pregnancy testing, CT or ultrasound.

  • Medication for nausea and vomiting when appropriate
  • Oral rehydration when tolerated
  • IV fluids for clinically significant dehydration
  • Electrolyte replacement when needed
  • Treatment directed at an identified cause
  • Monitoring or transfer for hospital-level conditions

Medication choice depends on age, pregnancy status, heart rhythm, other medicines and the suspected diagnosis. A specific medication is not promised before evaluation.

Diarrhea Evaluation

The care team assesses frequency, duration, blood or mucus, fever, abdominal pain, hydration and relevant exposures. Seek prompt care for black or bloody stool, severe pain, high fever, confusion, fainting, little urination, frequent vomiting or six or more loose stools in a day.

Not every case needs testing. When clinically appropriate, a physician may order blood, urine or selected stool studies. Treatment focuses on the cause and hydration needs.

Do not automatically use anti-diarrheal medicine when fever, bloody stool or suspected infection is present without medical guidance.

Infants and children: Seek prompt care for fewer wet diapers, dry mouth, no tears, sunken eyes or soft spot, unusual sleepiness, irritability, reduced interaction, inability to drink, frequent vomiting or diarrhea, blood in vomit or stool, or severe pain. Any fever in a baby younger than 12 weeks needs prompt medical attention.
ER for Dehydration

Dehydration Evaluation and IV Fluids

Vomiting and diarrhea are common causes of dehydration, but fever, heat, heavy sweating, medication, uncontrolled diabetes and difficulty drinking can also contribute.

Adult Warning Signs

  • Extreme thirst or dry mouth
  • Dark urine or urinating less often
  • Fatigue, weakness or dizziness
  • Rapid heartbeat
  • Headache or muscle cramps
  • Confusion or fainting when severe

Infant & Child Signs

  • Dry mouth or tongue
  • Fewer wet diapers or reduced urination
  • No tears when crying
  • Sunken eyes, cheeks or soft spot
  • Unusual sleepiness or low energy
  • Difficulty drinking or keeping fluids down

Physician-Directed Treatment

The team assesses vital signs, fluid loss, urine output and ability to drink. Blood and urine tests may identify electrolyte imbalance, kidney stress, infection or another cause.

Care may include oral rehydration, IV fluids, electrolyte replacement, nausea medication and treatment of the underlying illness.

Individualized care: Not every patient needs an IV. Oral rehydration may be appropriate when drinking is safe and effective. Severe dehydration can require close monitoring or hospital transfer.
Appendicitis ER Houston

Suspected Appendicitis Evaluation

Appendicitis is inflammation of the appendix and is a medical emergency. Without timely treatment, the appendix may rupture and spread infection within the abdomen.

Emergency physicians reviewing abdominal imaging for suspected appendicitis
SIGNS

Possible Appendicitis Symptoms

Symptoms can vary, especially in children, older adults and pregnant patients.

Common symptom pattern
  • Pain beginning near the belly button and moving lower right
  • Pain that starts suddenly or wakes a person
  • Symptoms worsening over several hours
  • Pain with walking, coughing, deep breathing or movement
  • Loss of appetite, nausea, vomiting or fever
  • Swelling, constipation, diarrhea or difficulty passing gas

Not everyone has a typical pattern. Seek emergency evaluation for severe, localized or worsening pain.

TEST

How Appendicitis Is Evaluated

Clinical examination and on-site testing help assess the appendix and other causes.

Testing may include
  • Blood tests for infection, inflammation and dehydration
  • Urinalysis for urinary infection or kidney stones
  • Pregnancy testing when relevant
  • Abdominal ultrasound
  • CT scanning

Test selection depends on age, pregnancy status, examination findings and clinical judgment.

Emergency evaluation and transfer: NorthStar can evaluate and stabilize suspected appendicitis and arrange transfer when surgical care is required. This page does not claim an on-site appendix operation, abdominal surgeon or operating room.

Helpful Answers

Abdominal & Digestive Emergency FAQs

Can NorthStar diagnose the cause of abdominal pain?

NorthStar can perform an emergency assessment and order appropriate on-site laboratory and imaging tests. Some conditions still require specialist consultation, additional testing or hospital transfer.

Should I go to urgent care or the ER for appendicitis symptoms?

Appendicitis is a medical emergency. An ER is appropriate because diagnosis may require blood work, urinalysis and advanced imaging, followed by rapid surgical referral or transfer.

Seek prompt care for bloody or black stool, severe pain, frequent vomiting, dehydration, confusion, high fever, six or more loose stools in a day or symptoms in a high-risk patient.

Can I receive an IV for dehydration?

IV fluids are available when the physician determines they are medically appropriate. Some patients can rehydrate orally, while severe dehydration may require IV treatment and closer monitoring.

Can a child receive treatment for dehydration?

Yes. NorthStar provides pediatric emergency care. Infants and children with reduced urination, no tears, dry mouth, unusual sleepiness or inability to drink should receive prompt medical assessment.

Do you have an abdominal pain specialist or gastroenterologist on site?

NorthStar provides physician-led emergency evaluation and confirmed diagnostic services. This page does not claim a dedicated on-site gastroenterologist or digestive specialty clinic.
