Stomach and back pain at the same time is often a coincidence of two separate problems, but the two can also share a single cause. Because organs in your abdomen sit close to the muscles and nerves of your spine, a problem in one area can refer pain to the other. Common culprits range from harmless ones like gas, constipation, or a pulled muscle to conditions that need prompt care, such as kidney stones, gallstones, or pancreatitis. When both pains are severe or will not let up, it is worth having them checked to rule out a serious cause.
Why Stomach and Back Pain Happen Together
Your abdominal organs and your spine share nerve pathways, so pain from an internal organ is often felt in the back, a phenomenon called referred pain. A kidney, the pancreas, or the gallbladder can send pain straight through to the back even though the organ itself sits toward the front. The reverse happens too: a spine or muscle problem can radiate discomfort around to the abdomen. This overlap is why the two pains so often show up together, and why pinpointing the source usually takes a proper exam and sometimes imaging.
Common Causes of Stomach and Back Pain at the Same Time
Some causes are minor and pass on their own, while others need treatment. These are the conditions most likely to produce both pains at once.
Gas, Bloating, and Constipation
The most common and least serious cause is trapped gas or constipation. A backed-up or gas-filled digestive tract can press outward and create pressure that is felt in both the lower abdomen and the lower back. This kind of pain usually eases once the gas or stool passes, and it often responds to hydration, movement, and fiber.
Muscle Strain
A pulled muscle in the core or back, from heavy lifting, a sudden movement, or poor posture, can produce pain that wraps around the torso and is felt in both the abdomen and the back at once. Strain-related pain typically worsens with movement and eases with rest.
Kidney Stones
Kidney stone pain usually begins in the back or side and travels around to the lower abdomen and groin, most often on one side. It can be severe and come in waves. Other signs include nausea, vomiting, or blood in the urine. Kidney stones warrant imaging to confirm the stone and plan treatment.
Kidney Infection
A urinary tract infection that reaches the kidney (pyelonephritis) can cause back or flank pain along with lower abdominal pain, usually with fever, chills, and painful or frequent urination. A kidney infection needs prompt medical treatment.
Pancreatitis
Inflammation of the pancreas causes upper abdominal pain that radiates to the back, often with nausea or vomiting. The pain tends to ease when you lean forward and worsen with sharp movements like coughing. Acute pancreatitis can stem from gallstones or heavy alcohol use; chronic pancreatitis brings intermittent pain in a pattern, often after meals, sometimes with weight loss, bloating, excess gas, or greasy stools.
Gallstones
Gallstones are hardened deposits in the gallbladder. They can cause pain in the upper right abdomen that extends to the back, often after a fatty meal. When a stone blocks a duct, the pain can be intense and steady and may need urgent care.
Peptic Ulcers
An ulcer, an erosion in the lining of the stomach or small intestine, can cause pain in the central or upper abdomen. When an ulcer is deep or perforates, that pain can travel to the back or shoulders as referred pain. Ulcer pain often changes with eating, either easing or worsening depending on the ulcer.
Appendicitis
Appendicitis usually starts as pain near the navel that settles in the lower right abdomen, and some people also feel it in the back. It tends to worsen steadily, often with fever, nausea, and loss of appetite. Appendicitis is a medical emergency; a suspected case needs care before the appendix can rupture.
Causes of Lower Abdomen and Back Pain in Females
Several causes of simultaneous stomach and back pain are specific to female anatomy, and they are a common reason women search for answers about lower abdomen and back pain together.
Menstrual Cramps and Endometriosis
Menstrual cramps commonly cause both lower abdominal and lower back pain. Endometriosis, where tissue like the uterine lining grows outside the uterus, can make that pain more severe and longer-lasting, and it deserves evaluation when cramps are disabling.
Ovarian Cysts
A fluid-filled cyst on an ovary can cause lower abdominal and back pain, especially if it grows large or ruptures, sending pain radiating through the pelvis and lower back.
Pregnancy
Pregnancy shifts posture and expands the uterus, which commonly brings on back pain and abdominal discomfort together as the body adapts. Sharp or severe pain during pregnancy should always be checked.
Pelvic Inflammatory Disease (PID)
PID, an infection of the reproductive organs, can cause severe lower abdominal pain that extends to the back, often with fever or unusual discharge. It needs prompt treatment to prevent complications.
Causes of Stomach and Back Pain in Males
Some causes are specific to male anatomy.
Prostatitis
Inflammation of the prostate gland can cause pain in the lower abdomen and back, sometimes with painful urination or pelvic discomfort.
Inguinal Hernia
An inguinal hernia, more common in men, happens when part of the intestine pushes through a weak spot in the abdominal wall, causing pain that can be felt in both the stomach and the back, often worse with lifting or straining.
Testicular Torsion
Testicular torsion, a twisting of the testicle that cuts off its blood supply, is a medical emergency. It causes sudden, severe pain in the scrotum and lower abdomen that can extend to the back and needs immediate care.
When to See a Doctor for Stomach and Back Pain
Occasional, mild stomach and back pain that passes on its own is rarely a concern. See a doctor, or visit an Atlanta imaging center for an ultrasound or MRI, if you notice:
- Nausea that lasts for days or steadily worsens
- Pain in the upper right abdomen
- Stomach pain that worsens with meals or follows a clear pattern
- Severe abdominal or back pain during pregnancy
- Pain that keeps returning or does not improve
Seek Emergency Care Right Away For:
- Intense stomach or back pain that feels unbearable
- Stomach pain with a fever, or pale-colored stool
- Intense back pain that radiates to the groin
- Sudden, severe pain in the scrotum or testicle
- Vomiting blood, or blood in the stool or urine
How Stomach and Back Pain Is Diagnosed and Treated
Because so many conditions can cause both pains, the right treatment starts with the right diagnosis. A doctor reviews your symptoms and history, then uses tests to narrow the cause, which may include blood or urine tests, an ultrasound, an endoscopy, an X-ray, or MRI imaging for a closer look. Treatment then targets the cause, whether that is passing a kidney stone, treating an infection, managing an ulcer, or addressing a musculoskeletal back problem.

Frequently Asked Questions
Why is my lower back and stomach hurting at the same time?
Most often it is something minor like gas, constipation, or a muscle strain, where pressure or tension is felt in both areas. It can also be referred pain from an organ such as a kidney, or, in women, a menstrual or ovarian cause. Pain that is severe, persistent, or paired with fever, vomiting, or blood should be checked promptly.
Can trapped gas cause lower back pain?
Yes, and it is one of the most common reasons for both pains at once. As pressure builds in a gas-filled or backed-up digestive tract, it can be felt in the lower back as well as the belly. It is usually harmless and passes on its own, so gas is worth ruling out before assuming something more serious.
When should I worry about stomach and back pain?
The warning signs are listed in the section above. In short, get care promptly for pain that is severe or unbearable, pain with a fever, or blood in your vomit, stool, or urine, and treat sudden, extreme pain as an emergency. Trust your instincts: if something feels seriously wrong, it is worth being seen.
What organ causes back and stomach pain together?
Several can. The kidneys, pancreas, gallbladder, and appendix all sit near the back or refer pain to it, so a problem in any of them can be felt in both the abdomen and the back. Imaging is often what tells them apart.
