Deep Core Burning? Why Your Pancreas Is Under Fire & Medical Next Steps

A deep, burning pain in your upper abdomen that seems to go straight through to your back can be frightening. Many people describe it as a "core fire" that won't ease up. One possible cause of this kind of pain is inflammation of the pancreas, a small but powerful organ that plays a major role in digestion and blood sugar control.

If you're feeling this kind of discomfort, it's important to understand what your pancreas does, why it may be "under fire," and what medical steps you should take next.

What Is the Pancreas and Why Does It Matter?

The pancreas is a gland located deep in your upper abdomen, behind your stomach. It has two critical jobs:

• Digestive support: It makes enzymes that help break down fats, proteins, and carbohydrates in your small intestine.
• Blood sugar control: It produces hormones like insulin and glucagon that regulate blood sugar levels.

When the pancreas becomes inflamed or damaged, these functions can be disrupted. That can lead to pain, digestive issues, unstable blood sugar, and potentially serious complications.

What Does "Deep Core Burning" Feel Like?

Pancreas-related pain often has specific features:

• Pain in the upper abdomen, often in the center or left side
• Pain that radiates to the back
• A burning, gnawing, or stabbing sensation
• Pain that may worsen after eating, especially fatty meals
• Nausea or vomiting
• Fever (in some cases)

This type of pain should not be ignored. While not all abdominal pain is serious, persistent or severe upper abdominal pain needs medical evaluation.

Acute Pancreatitis: When the Pancreas Is Inflamed

One of the most common causes of sudden pancreas pain is acute pancreatitis. This is a condition where the pancreas becomes inflamed over a short period of time.

Common Causes

According to established medical research and clinical guidelines, the most frequent causes of acute pancreatitis include:

• Gallstones (block the pancreatic duct)
• Heavy alcohol use
• Certain medications
• High triglyceride levels
• Abdominal trauma
• Infections
• Rare genetic conditions

Sometimes, no clear cause is found.

What Happens in Acute Pancreatitis?

Normally, digestive enzymes made by the pancreas activate after they reach the small intestine. In acute pancreatitis, these enzymes can activate too early—inside the pancreas itself. That causes the pancreas to start digesting its own tissue.

This leads to:

• Swelling
• Tissue damage
• Inflammation
• Severe pain

Most cases are mild and improve with proper treatment. However, some cases can become severe and lead to life-threatening complications, including infection, organ failure, or systemic inflammation.

Chronic Pancreatitis: Long-Term Damage

If inflammation keeps coming back or lasts a long time, it can turn into chronic pancreatitis.

Chronic inflammation can cause:

• Permanent damage to the pancreas
• Scarring
• Digestive enzyme deficiency
• Diabetes (due to insulin-producing cell damage)

Symptoms may include:

• Ongoing upper abdominal pain
• Unintended weight loss
• Greasy or oily stools (due to poor fat digestion)
• Blood sugar problems

Chronic pancreatitis is often linked to long-term alcohol use, genetic factors, or autoimmune disease.

When Is Pancreas Pain an Emergency?

Some symptoms suggest that pancreas inflammation may be severe and require urgent medical care.

Seek immediate medical attention if you have:

• Severe, persistent abdominal pain
• Pain that spreads to your back
• Fever with abdominal pain
• Rapid heart rate
• Persistent vomiting
• Yellowing of the skin or eyes (jaundice)
• Confusion or lightheadedness

These may signal complications such as infection, bile duct blockage, or systemic inflammation.

Do not wait this out at home if the pain is intense or worsening.

What to Do Next: Medical Evaluation

If you suspect your pancreas may be involved, your next step should be a medical evaluation.

A doctor may:

• Review your symptoms and medical history
• Perform a physical exam
• Order blood tests (including pancreatic enzyme levels like amylase and lipase)
• Use imaging tests such as:
  • Ultrasound
  • CT scan
  • MRI

These tests help confirm whether the pancreas is inflamed and identify the cause.

If you are experiencing upper abdominal pain that radiates to your back and want to understand whether your symptoms align with Acute Pancreatitis, a free AI-powered symptom checker can help you assess your risk level and determine how urgently you should seek medical care.

Treatment for Pancreatitis

Treatment depends on the severity and cause.

Mild Acute Pancreatitis

Most mild cases are treated in the hospital with:

• IV fluids
• Pain control
• Temporary fasting (to rest the pancreas)
• Gradual reintroduction of food

Many people recover within several days.

Severe Acute Pancreatitis

Severe cases may require:

• Intensive care monitoring
• Nutritional support through feeding tubes
• Antibiotics (if infection develops)
• Procedures to remove gallstones
• Surgery (in rare cases)

Chronic Pancreatitis Management

Chronic cases may involve:

• Pancreatic enzyme supplements
• Pain management strategies
• Diabetes management
• Dietary changes
• Alcohol cessation (if relevant)

How to Protect Your Pancreas

While not all causes of pancreas inflammation are preventable, there are steps that lower your risk:

• Limit or avoid alcohol
• Maintain healthy triglyceride levels
• Follow up on gallbladder symptoms
• Maintain a healthy weight
• Avoid smoking
• Take medications only as prescribed

If you have had pancreatitis before, careful follow-up with your doctor is essential.

Could It Be Something Else?

Not all upper abdominal pain is from the pancreas. Other conditions that can cause similar symptoms include:

• Acid reflux (GERD)
• Peptic ulcers
• Gallbladder disease
• Gastritis
• Kidney stones
• Heart conditions (especially in older adults)

This is why proper diagnosis matters. Guessing can delay appropriate treatment.

Don't Ignore Persistent Core Pain

A "deep core burning" sensation is your body signaling that something is wrong. The pancreas is a small organ, but when it becomes inflamed, the pain can be intense and the complications serious.

At the same time, most cases of mild acute pancreatitis improve with timely medical care. Early evaluation reduces risks and improves outcomes.

If you are experiencing:

• Severe abdominal pain
• Pain radiating to the back
• Nausea and vomiting with pain
• Fever or jaundice

You should speak to a doctor immediately. If symptoms feel life-threatening or rapidly worsening, seek emergency care.

The Bottom Line

Your pancreas plays a vital role in digestion and blood sugar control. When it becomes inflamed, it can feel like a deep internal burn that won't go away. Acute pancreatitis can range from mild to life-threatening, but early medical attention significantly improves outcomes.

Do not ignore persistent upper abdominal pain. Consider using a free, online symptom check for Acute Pancreatitis to better understand your symptoms, and most importantly, speak to a doctor about anything that could be serious or life threatening.

Listening to your body—and acting promptly—can protect your pancreas and your overall health.
