Abdominal Pain

Causes, Symptoms & When to Seek Care

Abdominal pain is one of the most common reasons adults visit an urgent care clinic. It can range from a mild, temporary discomfort to a signal of something that needs prompt medical attention. Understanding where the pain is located, how it feels, and what other symptoms accompany it helps determine the right level of care.

What is Abdominal Pain?

Abdominal pain refers to any discomfort felt between the chest and the pelvis. While we often call it a “stomachache,” the pain may actually be coming from any number of organs in the abdominal cavity — including the stomach, intestines, liver, gallbladder, pancreas, kidneys, bladder, or appendix. In some cases, pain felt in the abdomen originates from outside the digestive system entirely, such as from the lungs, heart, or abdominal wall muscles.

Most abdominal pain in adults is caused by benign, self-limiting conditions like gas, indigestion, or a mild viral infection. However, some causes are serious and require timely evaluation. The location, character, duration, and accompanying symptoms of the pain are key clues that help a provider identify what is going on.

Symptoms Associated With Abdominal Pain

Abdominal pain rarely occurs in isolation. The symptoms that accompany it provide important diagnostic information. Common associated symptoms include:

Nausea and vomiting — Often present with gastrointestinal infections, food poisoning, kidney stones, appendicitis, and gallbladder disease.

Diarrhea or loose stools — Common with viral gastroenteritis, food poisoning, irritable bowel syndrome, and inflammatory bowel conditions.

Constipation — Can cause significant abdominal cramping and bloating, and in severe cases may indicate a bowel obstruction.

Bloating and gas — Often associated with indigestion, irritable bowel syndrome, lactose intolerance, or swallowed air.

Fever — When present alongside abdominal pain, fever suggests an infectious or inflammatory cause such as appendicitis, diverticulitis, or a urinary tract infection.

Loss of appetite — A common accompaniment to many gastrointestinal conditions, particularly infections and inflammatory disease.

Painful or frequent urination — Suggests a urinary tract infection or kidney stone.

Blood in stool or urine — Requires prompt evaluation and should never be ignored.

Heartburn or acid reflux — A burning sensation rising from the stomach toward the chest, associated with GERD or gastritis.

Common Causes of Abdominal Pain in Adults

Abdominal pain has a wide range of causes. Understanding the most common ones helps patients recognize when home care is appropriate and when a visit is needed.

Indigestion (Dyspepsia) — A feeling of pain, fullness, or burning in the upper abdomen, often after eating. Usually caused by eating too quickly, fatty or spicy foods, alcohol, or stress. Typically resolves with antacids and dietary adjustment.

Gas and bloating — Trapped gas in the intestines causes cramping and discomfort that can be surprisingly intense. Usually temporary and relieved by passing gas or a bowel movement.

Gastroenteritis (Stomach flu) — A viral or bacterial infection of the stomach and intestines causing nausea, vomiting, diarrhea, cramping, and sometimes fever. Usually self-limiting but can cause dehydration requiring treatment.

Food poisoning — Caused by consuming contaminated food or drink. Symptoms typically begin within hours and include nausea, vomiting, diarrhea, and abdominal cramping. Most cases resolve within 24–48 hours.

Gastroesophageal Reflux Disease (GERD) — Chronic acid reflux causing burning pain in the upper abdomen and chest. Can mimic cardiac symptoms and often requires treatment.

Urinary Tract Infection (UTI) — Bacterial infection of the bladder or urinary tract causing lower abdominal pain or pelvic pressure, frequent urination, and burning. Very common in women. Treated with antibiotics.

Kidney Stones — Mineral deposits that form in the kidneys and can cause severe, cramping pain in the flank, side, or lower abdomen as they move through the urinary tract. Pain is often described as one of the most intense a person can experience.

Constipation — Difficulty passing stools or infrequent bowel movements, causing cramping, bloating, and lower abdominal pressure.

Irritable Bowel Syndrome (IBS) — A chronic functional disorder causing recurring abdominal pain, bloating, and alternating diarrhea and constipation. Symptoms are often triggered by stress or certain foods.

Appendicitis — Inflammation of the appendix, typically causing pain that begins around the navel and migrates to the lower right abdomen. Often accompanied by fever, nausea, and loss of appetite. Appendicitis is a medical emergency requiring surgical evaluation.

Gallstones / Gallbladder Disease — Hardened deposits in the gallbladder causing sharp, cramping pain in the upper right abdomen, often after eating fatty foods. Can escalate to acute cholecystitis, which requires urgent care.

Diverticulitis — Inflammation or infection of small pouches in the colon wall, causing lower left abdominal pain, fever, and change in bowel habits. More common in adults over 50.

Peptic Ulcer Disease — Open sores in the stomach lining or small intestine causing a burning or gnawing pain in the upper abdomen, often relieved temporarily by eating or antacids.

Pancreatitis — Inflammation of the pancreas causing severe upper abdominal pain that often radiates to the back. Associated with nausea, vomiting, and fever. Can be a serious condition requiring urgent evaluation.

Hernia — Occurs when an organ or tissue pushes through a weak spot in the abdominal wall. Can cause localized pain or bulging, particularly with exertion or straining.

Types of Abdominal Pain by Location

Where the pain is felt is one of the most important clues to its cause:

Upper right abdomen — Gallbladder disease, gallstones, liver conditions, or right-sided pneumonia.

Upper left abdomen — Gastritis, peptic ulcer, pancreatitis, or spleen-related conditions.

Upper center (epigastric) — GERD, indigestion, gastritis, peptic ulcer, or — importantly — referred pain from a cardiac event.

Lower right abdomen — Appendicitis, kidney stone, ovarian cyst, or groin hernia.

Lower left abdomen — Diverticulitis, kidney stone, constipation, or ovarian conditions in women.

Lower center (suprapubic) — Urinary tract infection, bladder conditions, or pelvic inflammatory disease.

Generalized / diffuse pain — Viral gastroenteritis, gas, IBS, early appendicitis, or in severe cases, peritonitis.

How is Abdominal Pain Treated?

Treatment depends entirely on the underlying cause. At Vitality Urgent Care, our providers assess your symptoms, perform a physical examination, and use on-site diagnostic tools to guide treatment decisions.

For mild to moderate causes:

Antacids or acid reducers for indigestion, GERD, and gastritis
Antibiotics for bacterial infections including UTIs and some gastrointestinal infections
Anti-nausea medications (antiemetics) for nausea and vomiting
IV fluids for dehydration caused by vomiting, diarrhea, or poor oral intake
Pain management guidance and medication as appropriate
Dietary recommendations and follow-up instructions

Diagnostic tools available on-site at Vitality:

Urinalysis — to evaluate for UTI, kidney stones, or blood in urine
Complete blood count (CBC) and metabolic panels — to assess for infection, inflammation, or organ function
Pregnancy testing — essential in women of reproductive age with lower abdominal pain
On-site laboratory testing to guide accurate diagnosis

When imaging is needed — Some conditions such as appendicitis, gallstones, and kidney stones require ultrasound or CT imaging for confirmation. If imaging is needed beyond our on-site capabilities, we will refer you promptly to the appropriate facility.

How Long Does Abdominal Pain Last?

Duration varies widely by cause. Gas and indigestion typically resolve within a few hours. Viral gastroenteritis usually improves within 1–3 days. Food poisoning generally resolves within 24–48 hours. UTIs begin improving within 1–2 days of starting antibiotics.

Pain that persists beyond 24–48 hours without improvement, or that is worsening rather than improving, always warrants a provider evaluation — even if it initially seemed mild.

Complications of Untreated Abdominal Pain

Ignoring persistent or worsening abdominal pain can allow underlying conditions to progress to serious complications:

Appendicitis left untreated can rupture, causing life-threatening peritonitis
Untreated UTIs can progress to kidney infections (pyelonephritis)
Unmanaged kidney stones can cause urinary obstruction and kidney damage
Untreated gallbladder disease can escalate to acute cholecystitis or gallbladder rupture
Dehydration from prolonged vomiting or diarrhea can become severe, particularly in older adults
Delayed diagnosis of diverticulitis can lead to abscess formation or bowel perforation

When in doubt, it is always safer to have abdominal pain evaluated by a provider than to wait and see.

How to Prevent Common Causes of Abdominal Pain

While not all causes can be prevented, many of the most common ones can be reduced with healthy habits:

Eat regular, balanced meals and avoid overeating or eating too quickly
Limit fatty, fried, and spicy foods if you are prone to indigestion or GERD
Stay well hydrated — adequate fluid intake supports digestion and urinary health
Wash hands thoroughly before eating and after using the restroom to reduce infection risk
Stay current on food safety practices — refrigerate leftovers promptly and avoid undercooked meats
Exercise regularly to support healthy bowel function and reduce constipation
Limit alcohol consumption, which irritates the stomach lining and can trigger gastritis
Manage stress — the gut and brain are closely connected, and chronic stress worsens IBS and GERD

How We Evaluate Abdominal Pain at Vitality Urgent Care

Abdominal pain is one of the most diagnostically complex complaints we see — the same symptom can have dozens of different causes ranging from benign to serious. Our evaluation is structured to identify the most likely cause efficiently and safely.

We begin with a detailed history. We ask about the location of the pain, how it started (sudden versus gradual), how long it has been present, its character (sharp, cramping, burning, dull), and whether it radiates to other areas such as the back, shoulder, or groin. We ask about associated symptoms — nausea, vomiting, fever, changes in bowel habits, urinary symptoms, and appetite. For women of reproductive age, menstrual history and the possibility of pregnancy are always part of the assessment.

The physical examination focuses on the abdomen. We assess all four quadrants for tenderness, rigidity, distension, and signs of peritoneal irritation such as guarding or rebound tenderness — findings that suggest a more serious underlying process. We listen to bowel sounds and check for organ enlargement.

We take vital signs including temperature, blood pressure, heart rate, and oxygen saturation. Abnormal vitals can signal infection, dehydration, or a more urgent condition. Based on the history and physical findings, we order targeted on-site laboratory tests — urinalysis, blood counts, metabolic panels, pregnancy test, or lipase — to narrow the diagnosis further.

If our evaluation suggests a condition that requires imaging or a higher level of care — such as suspected appendicitis, bowel obstruction, or aortic pathology — we will communicate that clearly, provide appropriate stabilization, and arrange prompt transfer or referral. Our goal is to give every patient a clear explanation of what we found, what it means, and what the next steps are.

Frequently Asked Questions

Can urgent care diagnose the cause of abdominal pain? Yes. We can evaluate your symptoms, perform a physical exam, and run on-site lab tests including urinalysis, blood counts, and pregnancy testing to identify the most likely cause. For conditions requiring imaging such as a CT scan or ultrasound, we will refer you promptly to the appropriate facility.

When is abdominal pain an emergency? Seek emergency care for sudden severe pain, pain with chest symptoms, a rigid abdomen, vomiting blood, bloody stools, or signs of shock. These may indicate appendicitis, a ruptured organ, a bowel obstruction, or a cardiac event. When in doubt, go to the ER.

What causes sharp stabbing pain in the abdomen? Sharp, localized pain can indicate appendicitis (lower right), gallstones (upper right), kidney stones (flank or lower abdomen), or a perforated ulcer (upper center). Sharp pain should be evaluated promptly, especially if it is worsening or accompanied by fever.

Can stress cause abdominal pain? Yes. The gut and brain are closely connected through the gut-brain axis. Stress and anxiety commonly trigger or worsen conditions like IBS, acid reflux, and functional abdominal pain. Managing stress is an important part of managing these conditions long-term.

How do I know if my abdominal pain is serious? Pain that is severe, sudden, worsening rather than improving, or accompanied by fever, vomiting, bloody stool, or changes in consciousness is more likely to be serious. Pain that has been mild and stable for several days with no new symptoms is less likely to represent an emergency — but still warrants evaluation if it has not resolved.

Can abdominal pain be caused by something other than a digestive problem? Yes. Kidney infections, kidney stones, UTIs, ovarian cysts, pelvic inflammatory disease, and even cardiac conditions can all present as abdominal pain. This is why a thorough clinical evaluation — not just self-diagnosis — is important for unexplained or persistent abdominal pain.

What is the most common cause of abdominal pain in adults? The most common causes seen in urgent care are gastroenteritis, nonspecific abdominal pain, UTIs, constipation, and indigestion. Gallstones, kidney stones, diverticulitis, and appendicitis are less common but frequently seen and require prompt evaluation.
